安装各种依赖包和环境所需包 ...
https://lug.ustc.edu.cn/wiki/mirrors/help/centos
可以把yum源改成上面这个
yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers php以及连接mysql的组件 yum -y install httpd php php-mysql apache依赖 yum -y install httpd-manual mod_ssl mod_perl mod_auth_mysql php依赖 yum -y install php-gd php-xml php-mbstring php-ldap php-pear php-xmlrpc php-bcmath php-snmp lm_sensors lm_sensors-devel perl-DBD-MySQL yum -y install mysql-connector-odbc mysql-devel libdbi-dbd-mysql mysql mysql-server yum -y install net-snmp net-snmp-utils net-snmp-perl net-snmp-devel beecrypt-devel yum -y install php-gd php-bcmath elfutils beecrypt php-snmp lm_sensors yum -y install net-snmp net-snmp-devel net-snmp-utils yum -y install curl curl-devel yum -y install fping ##zabbix 使用 fping 替代了 ping 作为 icmp 的工具
mysql修改配置文件，因为yum源安装的是5.1版本，给一个配置模板...模板好像是5.5的
[mysqld] user = mysql datadir = /export/zabbix/mysql_data socket = /export/zabbix/mysql_socket/mysql.sock port = 3306 default-character-set = utf8 [client] port = 3306 socket = /export/zabbix/mysql_socket/mysql.sock [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid #--- GLOBAL ---# character-set-server = utf8 log-error = /export/zabbix/mysql_log/error.log pid-file = /export/zabbix/mysql_data/mysql.pid slow-query-log slow_query_log_file = /export/zabbix/mysql_log/slow.log tmpdir = /export/zabbix/mysql_tmp/ long_query_time = 1 #--------------# thread_concurrency = 16 thread_cache_size = 512 table_open_cache = 16384 table_definition_cache = 16384 sort_buffer_size = 2M join_buffer_size = 2M read_buffer_size = 4M read_rnd_buffer_size = 4M key_buffer_size = 64M myisam_sort_buffer_size = 64M tmp_table_size = 256M max_heap_table_size = 256M open_files_limit = 65535 #query_cache_size = 2G #--- NETWORK ---# back_log = 1024 max_allowed_packet = 16M interactive_timeout = 300 wait_timeout = 300 skip-external-locking max-connections = 1000 skip-name-resolve #--- REPL ---# server-id = 1073306 log-bin = mysql-bin binlog_format = mixed expire_logs_days = 7 relay-log = relay-log replicate-ignore-db = test log_slave_updates skip-slave-start #--- INNODB ---# default-storage-engine = INNODB innodb_data_home_dir = /export/zabbix/mysql_data innodb_data_file_path = ibdata1:256M:autoextend innodb_file_per_table innodb_log_group_home_dir = /export/zabbix/mysql_log innodb_buffer_pool_size = 10G innodb_additional_mem_pool_size = 128M innodb_log_files_in_group = 3 innodb_log_file_size = 1024M innodb_log_buffer_size = 16M innodb_flush_log_at_trx_commit = 1 innodb_lock_wait_timeout = 120 innodb_flush_method = O_DIRECT innodb_max_dirty_pages_pct = 75 innodb_io_capacity = 1000 innodb_thread_concurrency = 32 innodb_open_files = 65535 innodb_write_io_threads = 8 innodb_read_io_threads = 8 [mysqldump] quick max_allowed_packet = 128M [mysql] no-auto-rehash default-character-set=utf8 [myisamchk] key_buffer_size = 128M sort_buffer_size = 128M read_buffer = 2M write_buffer = 2M [mysqlhotcopy] interactive-timeout
不细说MySQL的部署过程了，大致过程
1、建数据目录、日志目录、tmp目录
2、chown -R mysql.mysql 数据目录、日志目录、tmp目录
3、初始化mysql_install_db --defaults-file=/etc/my.cnf &
4、启动mysqld_safe --defaults-file=/etc/my.cnf &
5、系统建zabbix组合用户groupadd zabbix;useradd -g zabbix -d /home/zabbix -s /sbin/nologin zabbix
6、解压zabbix，编译配置参数说明：
--enable-server 安装 Zabbix Server
--enable-proxy 安装 Zabbix Proxy
--enable-agent 安装 Zabbix Agent
--with-mysql 使用 mysql 做数据库服务器
--with-net-snmp 支持 SNMP
--with-libcurl 支持 curl，用于 web 监控
我不需要网络设备监控，监控机器比较少，所以不用proxy和snmp，编译后的路径按照自己喜好放置吧
./configure --prefix=/usr/local/zabbix --with-mysql --enable-server --enable-agent --with-libcurl
编译完会显示以下信息
Configuration: Detected OS: linux-gnu Install path: /usr/local/zabbix Compilation arch: linux Compiler: gcc Compiler flags: -g -O2 -I/usr/include/mysql -g -pipe -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -fno-strict-aliasing -fwrapv -fPIC -DUNIV_LINUX -DUNIV_LINUX Enable server: yes Server details: With database: MySQL WEB Monitoring: cURL Native Jabber: no SNMP: no IPMI: no SSH: no ODBC: no Linker flags: -rdynamic -L/usr/lib64/mysql Libraries: -lm -ldl -lrt -lresolv -lmysqlclient -lcurl Enable proxy: no Enable agent: yes Agent details: Linker flags: -rdynamic Libraries: -lm -ldl -lrt -lresolv -lcurl Enable Java gateway: no LDAP support: no IPv6 support: no *********************************************************** * Now run 'make install' * * * * Thank you for using Zabbix! * * <http://www.zabbix.com> * ***********************************************************
继续make install
7、MySQL建zabbix库、用户
insert into mysql.user(User,Host,Password) values ('zabbix','%',password('zabbix'));
flush privileges;grant all privileges on zabbix.* to 'zabbix'@'%';
show grants for zabbix; ##yum装的mysql5.1比较操蛋
create database zabbix
mysql> show grants for zabbix; +-------------------------------------------------------------------------------------------------------+ | Grants for zabbix@% | +-------------------------------------------------------------------------------------------------------+ | GRANT USAGE ON *.* TO 'zabbix'@'%' IDENTIFIED BY PASSWORD '*DEEF4D7D88CD046ECA02A80393B7780A63E7E789' | | GRANT ALL PRIVILEGES ON `zabbix`.* TO 'zabbix'@'%' | +-------------------------------------------------------------------------------------------------------+ 2 rows in set (0.00 sec) mysql> GRANT ALL PRIVILEGES ON `zabbix`.* TO 'zabbix'@'%' IDENTIFIED BY PASSWORD '*DEEF4D7D88CD046ECA02A80393B7780A63E7E789' -> ; Query OK, 0 rows affected (0.00 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec)
8、注意依次导入./database/mysql/schema.sql ./database/mysql/images.sql ./database/mysql/data.sql
mysql -uzabbix -pzabbix zabbix <./database/mysql/schema.sql
mysql -uzabbix -pzabbix zabbix <./database/mysql/images.sql
mysql -uzabbix -pzabbix zabbix <./database/mysql/data.sql
9、检查一下/etc/services里面是否有以下四行，如果没有就加上
zabbix-agent 10050/tcp # Zabbix Agent zabbix-agent 10050/udp # Zabbix Agent zabbix-trapper 10051/tcp # Zabbix Trapper zabbix-trapper 10051/udp # Zabbix Trapper
10、拷贝zabbix目录下的frontend/php内容到http server的主目录下：
cp -r frontends/php/* /var/www/html/zabbix/
11、启动Apache
service httpd start
将 Apache 设置为开机自动启动
chkconfig --add httpd
chkconfig --level 345 httpd on
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
vim /etc/httpd/conf/httpd.conf
找到#ServerName www.example.com:80 把#去掉，再重启apache即可，浏览器访问一下试试
12、修改zabbix_server配置文件
参考博文修改的内容
[root@localhost zabbix-2.0.2]# sed -i 's/^DBUser=.*$/DBUser=zabbix/g' /usr/local/zabbix/etc/zabbix_server.conf [root@localhost zabbix-2.0.2]# sed -i 's/^.*DBPassword=.*$/DBPassword=111111/g' /usr/local/zabbix/etc/zabbix_server.conf [root@localhost zabbix-2.0.2]# cp -r frontends/php /var/www/html/zabbix [root@localhost zabbix-2.0.2]# cp misc/init.d/fedora/core/zabbix_server /etc/init.d/ [root@localhost zabbix-2.0.2]# cp misc/init.d/fedora/core/zabbix_agentd /etc/init.d/ [root@localhost zabbix-2.0.2]#sed -i 's/BASEDIR=\/usr\/local/BASEDIR=\/usr\/local\/zabbix/g' /etc/init.d/zabbix_server [root@localhost zabbix-2.0.2]#sed -i 's/BASEDIR=\/usr\/local/BASEDIR=\/usr\/local\/zabbix/g' /etc/init.d/zabbix_agentd
我修改的内容
LogFile=/tmp/zabbix_server.log
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix
DBSocket=/export/zabbix/mysql_socket/mysql.sock
FpingLocation=/usr/sbin/fping
要安装fping 下载地址：http://fping.org/ 安装： tar -zxvf fping.tar.gz cd fping/ ./configure make && make install which fping <- FpingLocation的配置安装这个修改 fping failed: "(null): can't create socket (must run as root?) : Protocol not supported" /usr/local/sbin/fping: can't create raw socket (must run as root?) : Operation not permitted 登录zabbix用户验证确实zabbix用户无法使用fping，权限问题，修改权限 chown root:root /usr/local/sbin/fping chmod u+s /usr/local/sbin/fping
如果启动的时候提示pid找不到，那就改一下pid的相关项
然后做一下软连或者加上环境变量
[root@zabbixserver mpm]# cd /bin/ [root@zabbixserver bin]# ln -s /usr/local/zabbix/bin/zabbix_sender zabbix_sender [root@zabbixserver bin]# ln -s /usr/local/zabbix/bin/zabbix_get zabbix_get
13、修改php.ini配置文件
参考博文修改的内容
[root@localhost ~]#sed -i 's/^\(.*\)date.timezone =.*$/date.timezone = Asia\/Shanghai/g' /etc/php.ini [root@localhost ~]#sed -i 's/^\(.*\)post_max_size =.*$/post_max_size = 16M/g' /etc/php.ini [root@localhost ~]#sed -i 's/^\(.*\)max_execution_time =.*$/max_execution_time = 300/g' /etc/php.ini [root@localhost ~]#sed -i 's/^\(.*\)max_input_time =.*$/max_input_time = 300/g' /etc/php.ini [root@localhost ~]# /etc/init.d/zabbix_server start [root@localhost ~]# /etc/init.d/zabbix_agentd start [root@localhost ~]# /etc/init.d/httpd start
修改完php配置需要重启zabbix_server和apache
可以访问zabbix页面进行配置，下面提示连接不到MySQL
function DBconnect(&$error) {}代码段，代码里面没有指定socket，所以一般不是这块问题。
function DBconnect(&$error) { global $DB; if (isset($DB['DB'])) { $error = _('Cannot create another database connection.'); return false; } $result = true; $DB['DB'] = null; // global db handler $DB['TRANSACTIONS'] = 0; // level of a nested transation $DB['TRANSACTION_NO_FAILED_SQLS'] = true; // true - if no statements failed in transaction, false - there are failed statements $DB['SELECT_COUNT'] = 0; // stats $DB['EXECUTE_COUNT'] = 0; if (!isset($DB['TYPE'])) { $error = 'Unknown database type.'; $result = false; } else { $DB['TYPE'] = zbx_strtoupper($DB['TYPE']); switch ($DB['TYPE']) { case ZBX_DB_MYSQL: $DB['DB'] = @mysqli_connect($DB['SERVER'], $DB['USER'], $DB['PASSWORD'], $DB['DATABASE'], $DB['PORT']); if (!$DB['DB']) { $error = 'Error connecting to database ['.trim(mysqli_connect_error()).']'; $result = false; } else { DBexecute('SET NAMES utf8'); } if ($result) { $dbBackend = new MysqlDbBackend(); } break; case ZBX_DB_POSTGRESQL: $pg_connection_string = (!empty($DB['SERVER']) ? 'host=\''.pg_connect_escape($DB['SERVER']).'\' ' : ''). 'dbname=\''.pg_connect_escape($DB['DATABASE']).'\' '. (!empty($DB['USER']) ? 'user=\''.pg_connect_escape($DB['USER']).'\' ' : ''). (!empty($DB['PASSWORD']) ? 'password=\''.pg_connect_escape($DB['PASSWORD']).'\' ' : ''). (!empty($DB['PORT']) ? 'port='.pg_connect_escape($DB['PORT']) : ''); $DB['DB']= @pg_connect($pg_connection_string); if (!$DB['DB']) { $error = 'Error connecting to database'; $result = false; } elseif (false !== ($pgsql_version = pg_parameter_status('server_version'))) { if ((int) $pgsql_version >= 9) { // change the output format for values of type bytea from hex (the default) to escape DBexecute('SET bytea_output = escape'); } } if ($result) { $dbBackend = new PostgresqlDbBackend(); } break; case ZBX_DB_ORACLE: $connect = ''; if (!empty($DB['SERVER'])) { $connect = '//'.$DB['SERVER']; if ($DB['PORT'] != '0') { $connect .= ':'.$DB['PORT']; } if ($DB['DATABASE']) { $connect .= '/'.$DB['DATABASE']; } } $DB['DB'] = @oci_connect($DB['USER'], $DB['PASSWORD'], $connect); if ($DB['DB']) { DBexecute('ALTER SESSION SET NLS_NUMERIC_CHARACTERS='.zbx_dbstr('. ')); } else { $error = 'Error connecting to database'; $result = false; } if ($result) { $dbBackend = new OracleDbBackend(); } break; case ZBX_DB_DB2: $connect = ''; $connect .= 'DATABASE='.$DB['DATABASE'].';'; $connect .= 'HOSTNAME='.$DB['SERVER'].';'; $connect .= 'PORT='.$DB['PORT'].';'; $connect .= 'PROTOCOL=TCPIP;'; $connect .= 'UID='.$DB['USER'].';'; $connect .= 'PWD='.$DB['PASSWORD'].';'; $DB['DB'] = @db2_connect($connect, $DB['USER'], $DB['PASSWORD']); if (!$DB['DB']) { $error = 'Error connecting to database'; $result = false; } else { $options = array( 'db2_attr_case' => DB2_CASE_LOWER, ); db2_set_option($DB['DB'], $options, 1); if (isset($DB['SCHEMA']) && $DB['SCHEMA'] != '') { DBexecute('SET CURRENT SCHEMA='.zbx_dbstr($DB['SCHEMA'])); } } if ($result) { $dbBackend = new Db2DbBackend(); } break; case ZBX_DB_SQLITE3: if (file_exists($DB['DATABASE'])) { init_sqlite3_access(); lock_sqlite3_access(); try{ $DB['DB'] = @new SQLite3($DB['DATABASE'], SQLITE3_OPEN_READWRITE); } catch (Exception $e) { $error = 'Error connecting to database'; $result = false; } unlock_sqlite3_access(); } else { $error = 'Missing database'; $result = false; } if ($result) { $dbBackend = new SqliteDbBackend(); } break; default: $error = 'Unsupported database'; $result = false; } } if ($result && !$dbBackend->checkDbVersion()) { $error = $dbBackend->getError(); $result = false; } if (false == $result) { $DB['DB'] = null; } return $result; }
1、mysql.sock文件位置问题
因为MySQL配置的路径各异，sock做个软连过去（上一步自检php环境，按照上面修改php.ini即可，别忘重启apach和zabbix）
cd /var/lib/mysql/ ;ln -s /export/zabbix/mysql_socket/mysql.sock mysql.sock
2、SELinux和iptables影响
service iptables stop
/usr/sbin/sestatus -v ##如果SELinux status参数为enabled即为开启状态
修改/etc/selinux/config 文件将SELINUX=enforcing改为SELINUX=disabled，然后reboot，注意最好先停掉mysql进程
3、测试
ie访问部署的这台机器比如192.168.1.2/zabbix，ie字体小，遨游和chrome好点
然后特么进不去页面，各种检查
zabbix log 有/tmp/zabbix_server.log 和 zabbix_agentd.log
httpd log /var/log/httpd/errlog。。。
然后想起来IE代理这个情况...买了个表
其他页面设置可以参考文章首的第一个链接
问题1：字体问题参考链接
http://blog.chinaunix.net/uid-11121450-id-3296646.html
问题2：页面的历史记录（history）乱码变成???>???>???
安装时在导入三个sql文件时，zabbix数据库中创建的表的字符集是latin1，修改为utf8，如果Zabbix里面没有建主机和监控项就drop databases，配置文件修改如下：
[mysqld] ##这个节点下面增加
default-character-set = utf8
http://www.haogongju.net/art/2418891
问题3：启动zabbix_server提示缺失lib模块
[root@zabbixserver lib]# service zabbix_server start zabbix_server: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No such file or directory [root@zabbixserver lib]# ln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib64/
下面的可以忽略
Zabbix自带的mysql监控的配置
因为Zabbix自带的监控脚本取的数据较少，还需要自己改一些东西，所以最后用的mysql_performance_monitor，所以带删除线的这块可以忽略
http://os.51cto.com/art/201104/253006.htm
http://my.oschina.net/zhongjuan/blog/89412
http://www.it165.net/os/html/201210/3677.html
上文中提到的xml和php获取地址
https://www.zabbix.com/wiki/howto/monitor/db/mysql/extensive_mysql_monitoring_including_replication
拿到xml以后，在zabbix中文界面里面的【组态】-【模板】的右边有一个【汇入】，把xml模板导入
php脚本需要放到监控机，配置文件目录/usr/local/zabbix/etc/
根据本机环境。 第一行加入：#!/usr/bin/php 在最后一行加入：?> 关闭调试：define('DEBUG',true); 为 define('DEBUG',False); 修改日志、数据文件路径： define('LOG',"/tmp/zabbix_".SYSTEM.".log"); define('DAT',"/tmp/zabbix_".SYSTEM.".dat"); define('UTIME',"/tmp/.zabbix_".SYSTEM.".utime"); define('DTIME',"/tmp/.zabbix_".SYSTEM.".dtime"); 修改：define('SYSTEM','mysql'.(DEBUG ? "-debug" : "")); 为：define('SYSTEM','mysql'); 打开系统日志功能：//system("zabbix_sender -z $server -i ".DAT." >> ".LOG); 为：system("zabbix_sender -z $server -i ".DAT." >> ".LOG);
注释file_put_contents(DAT,"$server $host 10051 ".SYSTEM.".$var $val\n",FILE_APPEND);且 下面增加以下文字： $cmd = "zabbix_sender -c $config_path -k ".SYSTEM.".$var -o $val -vv"; file_put_contents(DAT,"$cmd\n",FILE_APPEND); exec($cmd);
在zabbix_agentd.conf配置文件中加入
这个php报错还是需要注意的
UserParameter=mysql.daily,php /etc/zabbix/mysql.php daily 用户名 密码 UserParameter=mysql.live,php /etc/zabbix/mysql.php live 用户名 密码 daily:每天执行一次。【由zabbix_server轮询发起，默认86640秒即一天 zabbix agent类型 UDP协议】 live:按指定时间执行一次。【由zabbix_server轮询发起，默认120秒 zabbix agent类型 UDP协议】 php :执行php文件 /etc/zabbix/mysql.php:mysql.php文件所在的文件路径 用户名 密码：登录mysql数据库的账户与密码 重启zabbix_agentd
mysql.php里面还需要zabbix/bin下的部分执行文件的环境变量，否则会报一些错误，具体问题具体分析，修改mysql.php或者php.ini
sh: zabbix_sender: command not found
cd /usr/bin/ ;ln -s /usr/local/zabbix/bin/zabbix_sender zabbix_sender
ln -s /usr/local/zabbix/bin/zabbix_get zabbix_get
报错：
PHP Warning: Division by zero in /usr/local/zabbix/etc/mysql.php on line 470 PHP Warning: Division by zero in /usr/local/zabbix/etc/mysql.php on line 471 PHP Warning: Division by zero in /usr/local/zabbix/etc/mysql.php on line 472
chown zabbix.zabbix /tmp/zabbix_*
mysql.php 监控文件里面的命令执行失败大部分由于授权或者环境变量影响，/tmp下的日志文件属主权限、用户的.bash_profile是否导入，检查php zabbix_sender mysql的环境变量
因为Zabbix提供的监控脚本和监控项不太好用，所以决定使用第三方的一个插件mysql_performance_monitor！！！
【MPM】
1、安装环境
yum install -y perl-libwww-perl perl-File-Which perl-DBD-MySQL perl-Digest-SHA1 perl-Digest-SHA perl-Crypt-SSLeay perl-Time-HiRes
参考地址
http://blog.chinaunix.net/uid-451-id-3338674.html
http://www.fromdual.com/download#mpm
2、安装mpm
[root@zabbixserver package]# tar -zxvf mysql_performance_monitor-0.9.2.tar.gz [root@zabbixserver package]# mv mysql_performance_monitor_agent mpm [root@zabbixserver package]# mv mpm /usr/local/ #配置文件，配置详细看下面 [root@zabbixserver package]# vim /etc/zabbix_mpm.conf [root@zabbixserver package]# chown zabbix /etc/zabbix_mpm.conf [root@zabbixserver package]# mkdir /var/log/zabbix [root@zabbixserver package]# touch /var/log/zabbix/FromDualMySQLagent.log [root@zabbixserver package]# chown -R zabbix:zabbix /var/log/zabbix #UserParameter的值修改为：注意mpm配置位置 [root@zabbixserver mpm]# vim /usr/local/zabbix/etc/zabbix_agentd.conf UserParameter=FromDual.MySQL.check,/usr/local/mpm/FromDualMySQLagent.pl /usr/local/mpm/zabbix_mpm.conf
[root@zabbixserver bin]# usermod -G mysql zabbix
3、导入xml模板
修改主机系统名、Zabbix_server/agentd配置文件的必须一致，与zabbix web新建的主机名必须一致
xml模板没必要都导入，可以先将MySQL.mpm（前缀删了），对应agent配置也先加这一个，后期需要可以逐步加模板及监控项
MPM Server的配置（MPM Server监控自己zabbix server的MySQL）
[default] Type = mysqld Debug = 2 LogFile = /var/log/zabbix/FromDualMySQLagent.log CacheFileBase = /var/log/zabbix/cache/FromDualAgentCache Username = zabbix Password = zabbix MysqlHost = 127.0.0.1 MysqlPort = 3306 ZabbixServer = localhost Disabled = false [zabbixserver] Type = mysqld MysqlPort = 3306 Modules = mpm innodb mysql process server PidFile = /export/zabbix/mysql_data/mysql.pid
MPM Agent的配置
Type = mysqld Debug = 2 LogFile = /var/log/zabbix/FromDualMySQLagent.log CacheFileBase = /var/log/zabbix/cache/FromDualAgentCache Username = zabbix Password = zabbix MysqlHost = localhost MysqlPort = 3358 ZabbixServer = 192.168.201.107 Disabled = false [cobbler] Type = mysqld MysqlPort = 3306 Modules = mpm innodb mysql process server PidFile = /export/data/mysql/data/mysql.pid
4、报错及分析
（1）、MPM报找不到mysql.pid
#FromDualMySQLagent.log报找不到mysql.pid 15454:2014-06-27 10:28:33.222 - ERR : Cannot read PID file /export/zabbix/mysql_data/mysql.pid. Either file does not exist or I have no read permissions. Are you sure the process is running? #修改一下权限 [root@zabbixserver bin]# usermod -G mysql zabbix
（2）、MPM说某个模块不存在，分析
#报FromDualMySQLinnodb模块不存在 15454:2014-06-27 10:28:33.146 - ERR : Module FromDualMySQLinnodb does not exist. ERR : Can't locate Digest/SHA.pm in @INC (@INC contains: /usr/local/mpm/lib /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /usr/local/mpm/lib/InnoDbStatus.pm line 9. BEGIN failed--compilation aborted at /usr/local/mpm/lib/InnoDbStatus.pm line 9. Compilation failed in require at /usr/local/mpm/lib/FromDualMySQLinnodb.pm line 26. BEGIN failed--compilation aborted at /usr/local/mpm/lib/FromDualMySQLinnodb.pm line 26. Compilation failed in require at (eval 15) line 3. #先把mpm配置文件中的对应模块删除，zabbix web中主机关联的模板删除，然后重启agentd，看看是否还继续报错，如果不报了找对应模块的问题
#这个问题是因为perl少安装一个perl-Digest-SHA依赖包
下面的斜体部分都属于报错、排错部分，是针对某些非MPM官网包出现的问题，如果是官网下的MPM可以直接忽略...还是踏踏实实官网下载，别论坛或者扒别人的

扒了mpm代码
FromDualMySQLagent.pm的checkConnectionToZabbixServer
sub checkConnectionToZabbixServer { my $pServer = $_[0]; my $pPort = $_[1]; my $pHost = $_[2]; my $rc = 0; if ( $main::gParameter{'Debug'} >= INFO ) { &FromDualMySQLagent::mylog($main::gParameter{'LogFile'}, INFO, ' ' .

sendData.pm的sendData
sub sendData { my $values_ref = shift; my $list_ref = shift; my $rc = 0; if ( $main::gParameter{'Debug'} >= INFO ) { &FromDualMySQLagent::mylog($main::gParameter{'LogFile'}, INFO, ' ' .

sendCachedData.pm的sendCachedData
sub sendCachedData { my $pServer = $_[0]; my $pPort = $_[1]; my $rc = 0; if ( $main::gParameter{'Debug'} >= INFO ) { &FromDualMySQLagent::mylog($main::gParameter{'LogFile'}, INFO, ' ' .

做了个测试脚本
#!/usr/bin/perl my $cmd = "zabbix_sender --zabbix-server 127.0.0.1 --port 10051 --host 'zabbix_server' --key FromDual.server.check --value '1'"; system("$cmd >/dev/null 2>&1"); my $ret = $?; my $code = $ret >> 8; if ( ($ret >> 8) == 0 ) { printf "code 0" } else { printf "code is $code" }
[root@localhost cache]# zabbix_sender --zabbix-server 127.0.0.1 --port 10051 --host 'zabbixserver' --key FromDual.server.check --value '1' ;echo $? info from server: "processed: 0; failed: 1; total: 1; seconds spent: 0.000028" sent: 1; skipped: 0; total: 1
2
说明还是有问题，继续排查中...
返回值2是shell内建命令使用错误(Bash文档上有说明)
https://www.zabbix.com/documentation/2.0/manpages/zabbix_sender zabbix_sender的说明
因为在zabbix web页面中，没有模板是符合 FromDual.server.check的，所以他会报错
一定注意模板的重要性，会遇到两个比较常见的问题
1、就是上面的check失败，/var/log/zabbix/FromDualMySQLagent.log 报：
3348:2014-05-09 14:25:19.099 - INFO: FromDual Performance Monitor for MySQL (0.9.1) run started. 3348:2014-05-09 14:25:19.130 - WARN: localhost, 10051, zabbixserver 3348:2014-05-09 14:25:19.130 - WARN: Connection to zabbix server failed (rc=1305)! 3348:2014-05-09 14:25:19.130 - INFO: FromDual Performance Monitor for MySQL run finshed (rc=0).
2、zabbix web页面主机监控状态会显示为红色的Z，并提示：
Received empty response from Zabbix Agent at [192.168.10.217]. Assuming that agent dropped connection because of access permission
这就是Server自己的模板确实造成，模板要和agent监控的模块匹配
决定改下FromDualMySQLagent.pm的checkConnectionToZabbixServer模块默认的$key值
# This tag does NOT exist in templates!!! my $lKey = 'FromDual.server.check'; 改为 # This tag does NOT exist in templates!!! my $lKey = 'FromDual.MySQL.mpm.mpm_version'; 但是必须在/etc/zabbix_mpm.cnf的Modules中加入mpm
执行zabbix_sender测试
[root@zabbixserver cache]# zabbix_sender --zabbix-server 127.0.0.1 --port 10051 --host 'zabbixserver' --key FromDual.MySQL.mpm.mpm_version --value '1' ;echo $? info from server: "processed: 1; failed: 0; total: 1; seconds spent: 0.000042" sent: 1; skipped: 0; total: 1 0
但是！FromDualMySQLagent.log 然后开始报：
3801:2014-05-09 14:53:26.283 - INFO: FromDual Performance Monitor for MySQL (0.9.1) run started. 3801:2014-05-09 14:53:26.301 - ERR : Load of cache file failed. rc=1301 3801:2014-05-09 14:53:26.301 - INFO: FromDual Performance Monitor for MySQL run finshed (rc=0).
what the fuck...
sendCachedData.pm的sendCachedData的
my $cmd = "$exe --zabbix-server $pServer --port $pPort --input-file $main::gParameter{'CacheFile'} --with-timestamps"; my $ret = $?; $rc = 1301; if ( $main::gParameter{'Debug'} == DBG ) { &FromDualMySQLagent::mylog($main::gParameter{'LogFile'}, DBG, " (ret=$ret / rc=$rc)."); } if ( $ret == 0 ) { # Do not delete Cache File but just set it back to zero again &FromDualMySQLagent::clearCacheFile($main::gParameter{'CacheFile'}); } else { &FromDualMySQLagent::mylog($main::gParameter{'LogFile'}, ERR, " Load of cache file failed. rc=$rc"); }
测试：
[root@zabbixserver cache]# zabbix_sender --zabbix-server 127.0.0.1 --port 10051 --input-file /var/log/zabbix/cache/FromDualAgentCache.zabbixserver.cache --with-timestamps ;echo $? Sending failed. Use option -vv for more detailed output. 1
发现个问题，每次监控的mpm模块会把FromDualAgentCache.zabbixserver.cache文件中最后写入个空行，导致zabbix_sender读取失败
用其他模板中的模块去让他check即可解决
/usr/local/mpm/FromDualMySQLagent.pl /etc/zabbix_mpm.conf
在部署zabbix_agentd的时候报以下错误：
6274:2014-05-13 23:37:11.745 - INFO: FromDual Performance Monitor for MySQL (0.9.2) run started. 6274:2014-05-13 23:37:11.957 - ERR : Cannot read PID file /export/data/mysql/data/mysql.pid. Either file does not exist or I have no read permissions. Are you sure the process is running? 6274:2014-05-13 23:37:11.958 - INFO: FromDual Performance Monitor for MySQL run finshed (rc=0).
解决方法usermod -G mysql zabbix
以下错误可以使用软连
5941:2014-05-13 19:25:50.366 - INFO: FromDual Performance Monitor for MySQL (0.9.1) run started. 5941:2014-05-13 19:25:50.404 - ERR : DBI connect with database=mysql, host=localhost, port=3358 and user=zabbix failed: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) 5941:2014-05-13 19:25:50.404 - DBG : Database connection failed (rc=2400). 5941:2014-05-13 19:25:50.414 - ERR : DBI connect with database=mysql, host=localhost, port=3358 and user=zabbix failed: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) 5941:2014-05-13 19:25:50.414 - DBG : Database connection failed (rc=2600). 5941:2014-05-13 19:25:50.414 - INFO: FromDual Performance Monitor for MySQL run finshed (rc=0). mkdir -p /var/lib/mysql/ ;ln -s /export/data/mysql/tmp/mysql.sock mysql.sock
例如mkdir -p /var/lib/mysql/;cd /var/lib/mysql/ ;ln -s /export/data/mysql/tmp/mysql.sock mysql.sock
4、总结
上面基本上能遇到的问题都遇到了，总结一下：
1、Zabbix部署没什么难度，注意MySQL和php配置与Zabbix的一致即可，注意环境变量，若报找不到sock或者pid文件，但是找不到相关配置，最后办法可以ln做软连
2、mysql.php作为Zabbix自己的MySQL监控插件和Zabbix官网的监控模板不是很好用，推荐用MPM。MPM的原理就是通过/usr/local/mpm/FromDualMySQLagent.pl读取配置文件/etc/zabbix_mpm.conf中所需要的模块，然后调用/usr/local/mpm/lib下的各个模块读MySQL运行参数
3、别TM从什么网盘或者什么参考论坛下插件，一定要从第三方软件官网！查了一圈结果是MPM包的问题，官网的配上就好使
4、MPM不好使可以用zabbix_sender在agentd机器测试是否可以成功，MPM脚本中很多环节是依靠zabbix_sender的检查
5、在zabbix_server端可以用zabbix_get检查是否可以连通agentd端
6、MPM配置中的Modules中加上MPM他就会自动刷新，否则只能把脚本加到crontab中一分钟取一次数（http://blog.chinaunix.net/uid-451-id-3338674.html中最后“关于mpm的刷新频率”）
7、主机名、MPM和zabbix配置中的与zabbix web界面的要一致
8、MPM中Modules的模块一定要在zabbix web中导入相对应模板，否则会出现（下面仅实例，记得这个返回码是1）
[root@zabbixserver cache]# zabbix_sender --zabbix-server 127.0.0.1 --port 10051 --input-file /var/log/zabbix/cache/FromDualAgentCache.zabbixserver.cache --with-timestamps ;echo $? info from server: "processed: 123; failed: 234; total: 357; seconds spent: 0.000042" sent: 1; skipped: 0; total: 1 1
【Zabbix监控项目触发的动作，调用msmtp发邮件比较麻烦，使用msmtp配合mutt十分方便】
Zabbix监控动作传出的数据定义
$1 收件人 recipient=[email protected]
$2 标题 subject='服务器cobbler-MySQL server is down on cobbler的故障'
$3 邮件内容 message='MYSQL down'
【msmtp】
1、msmtp邮件插件下载地址：
http://sourceforge.net/projects/msmtp/files/msmtp/1.4.32/
[root@zabbixserver ~]# tar jxvf msmtp-1.4.32.tar.bz2 [root@zabbixserver ~]# cd ./msmtp-1.4.32 [root@zabbixserver msmtp-1.4.32]# ./configure --prefix=/usr/local/bin/msmtp ;make && make install ; [root@zabbixserver etc]# cd /usr/local/etc/ [root@zabbixserver etc]# ln -s /export/zabbix/msmtprc msmtprc [root@zabbixserver etc]# msmtp -P
2、msmtp配置参考：
http://www.docin.com/p-471069369.html
配置示例（使用时把配置文件的所有注释删掉）
[root@zabbixserver ~]# vim /usr/local/etc/msmtprc
account [email protected] host smtp.explain.com port 25 #特殊需修改，默认25 from [email protected] auth login tls off user username password passwd_user account default:[email protected] logfile /var/log/zabbix/zabbix_msmtp.log
touch /var/log/zabbix/zabbix_msmtp.log
chmod 600 .msmtprc
msmtp -P 命令测试msmtp配置是否正确
loaded system configuration file /usr/local/etc/msmtprc loaded user configuration file /root/.msmtprc falling back to default account using account default from /root/.msmtprc host = smtp.explain.com port = 25 timeout = off protocol = smtp domain = localhost auth = LOGIN user = username password = * passwordeval = (not set) ntlmdomain = (not set) tls = off tls_starttls = on tls_trust_file = (not set) tls_crl_file = (not set) tls_fingerprint = (not set) tls_key_file = (not set) tls_cert_file = (not set) tls_certcheck = on tls_force_sslv3 = off tls_min_dh_prime_bits = (not set) tls_priorities = (not set) auto_from = off maildomain = (not set) from = 605441885@qq.com dsn_notify = (not set) dsn_return = (not set) keepbcc = off logfile = /var/log/zabbix/zabbix_msmtp.log syslog = (not set) aliases = (not set) reading recipients from the command line
上面说明检查配置成功，如果有报错，对应报错修改配置内容或者配置文件所在位置
3、测试
一般telnet不通的，比如telnet smtp.sina.com 25失败的，那先看看端口是不是受限了
msmtp [email protected] 回车后输入内容，然后Ctrl+d尝试发送邮件，观察/var/log/zabbix/zabbix_msmtp.log
4、脚本
#! /bin/sh DEBUG=1 if [ $DEBUG -gt 0 ] then exec 2>>/export/zabbix/cache/zabbix_msmtp.log set -x fi FROM='[email protected]' MSMTP_ACCOUNT='[email protected]' # Parameters (as passed by Zabbix): # $1 : Recipient # $2 : Subject # $3 : Message recipient=$1 subject=$2 message=$3 date=`date --rfc-2822` sed 's/$/\r/' <<EOF | /usr/local/msmtp/bin/msmtp -C /usr/local/etc/msmtprc --account $MSMTP_ACCOUNT $recipient From: <$FROM> To: <$recipient> Subject: $subject Date: $date $message EOF
报警邮件有中文的话，foxmail收到邮件标题和内容都会是乱码，foxmail自动识别不好用，outlook比较好，但是太占用内存，网易的邮箱也还好，内容可以自己匹配字符集，但是标题也还是乱码。
可能遇到的报错
msmtp: /usr/local/etc/msmtprc: must have no more than user read/write permissions
把配置文件的权限修改一下
[root@zabbixserver etc]# chown zabbix,zabbix msmtprc [root@zabbixserver etc]# chmod og-rwx msmtprc [root@zabbixserver etc]# chmod u-wx msmtprc
建议把脚本放在zabbix_server.cnf默认的路径下
编译的path: zabbix/share/zabbix/alertscripts
然后授权zabbix
[root@zabbixserver alertscripts]# chown zabbix,zabbix msmtp.sh
5、测试
进入zabbix用户下，调用上述脚本测试，如果进不去zabbix用户，执行
[root@zabbixserver /]# usermod -s /bin/bash zabbix
【mutt】（mutt没有试用成功）
mutt邮件处理框图
http://blog.chinaunix.net/uid-20543672-id-3349607.html
我用的yum安装mutt
参考msmtp这里面的改配置文件
http://www.docin.com/p-471069369.html
[root@zabbixserver /]# vim muttrc [root@zabbixserver /]# cd /root/ [root@zabbixserver ~]# ln -s /export/zabbix/muttrc .muttrc
1、mutt配置muttrc内容
set use_from=yes
set realname="[email protected]" set sendmail="/path/msmtp" set editor="vi" set from="[email protected]"
如果不加set from="[email protected]" 会报下面的错误
[root@localhost export]# echo "hahahaha" | mutt -s "MySQL down" [email protected]
msmtp: the server did not accept the mail
msmtp: server message: 550 5.7.1 Client does not have permissions to send as this sender msmtp: could not send mail (account default from /root/.msmtprc) Error sending message, child exited 69 (Service unavailable.). Could not send the message.
2、脚本配置
脚本路径是zabbix_server配置文件控制的，如下，所以需要把脚本放到这个目录下
AlertScriptsPath=/usr/bin/
3、脚本
#!/bin/bash
echo "$3" | mutt -s "$2" $1
【Zabbix邮件报警设置】
邮件报警，参考：
报警脚本 -> http://waringid.blog.51cto.com/65148/1142579/ <- 不太好用，用mutt自己写个简单的
配置 ->http://www.centoscn.com/CentosServer/log/2013/0807/1168.html
MPM对于MySQL实例是否存活的alive的监控是基于自己MPM脚本的，但是如果MySQL已经down了，MPM采集不到数据，MPM脚本会报错而sender不出来数据，导致拿不到实际MySQL状态
自己建模板、项目、触发器，利用zabbix的net模块的端口监控MySQL是否存活（存活状态是否健康还需要其他类型监控），参考链接：
http://www.linuxidc.com/Linux/2013-05/83780.htm
选择一个用户组（可以先新建一个组，并把用户加到这个组）
用户的邮箱地址可以在点击在用户-示警媒介中添加和配置
新建示警媒介类型（管理-示警媒介类型-创建媒体类型）
在动作中添加群组以及动作行为（组态-动作-操作）切记配置完点击更新，再点击存档
【部署客户端】
客户端部署比较简单，因为在server这边编译时候已经带了客户端，可以直接把server这边的客户端打个包，复制到监控机。上面示例中的mpm配置是用zabbixserver自己mysql做的一个配置，可以参考上面的配置。
##最好先检查一下server与agent间网络是否通 ##server这边打好包，做分发 [root@zabbixserver ~]# cd /usr/local/ [root@zabbixserver local]# cp /path/zabbix-2.2.2/misc/init.d/fedora/core/zabbix_* zabbix/ [root@zabbixserver local]# tar -zcvf ./zabbix.tar.gz zabbix/ [root@zabbixserver local]# tar -zcvf ./mpm.tar.gz mpm/ [root@zabbixserver local]# scp ./zabbix.tar.gz root@ip:/usr/local/ [root@zabbixserver local]# scp ./mpm.tar.gz root@ip:/usr/local/ ##Agent监控机 [root@ip local]# tar -zxvf zabbix.tar.gz [root@ip local]# tar -zxvf mpm.tar.gz [root@ip local]# chown -R zabbix.zabbix zabbix [root@ip local]# chown -R zabbix.zabbix mpm [root@ip local]# groupadd zabbix;useradd -g zabbix -d /home/zabbix -s /sbin/nologin zabbix [root@ip local]# usermod -G mysql zabbix [root@ip local]# cd path/zabbix/;mkdir cache zabbix_tmp;chown -R zabbix.zabbix cache/ zabbix_tmp/ [root@ip etc]# vim /usr/local/mpm/zabbix_mpm.conf [default] Type = mysqld Debug = 2 LogFile = /export/zabbix/cache/FromDualMySQLagent.log CacheFileBase = /export/zabbix/cache/FromDualAgentCache Username = zabbix Password = zabbix MysqlHost = 127.0.0.1 MysqlPort = 3358 ZabbixServer = 172.22.209.54 Disabled = false [DB22484] Type = mysqld MysqlPort = 3358 Modules = mpm mysql process server innodb PidFile = /export/zabbix/mysql_data/mysql.pid [root@ip etc]# vim zabbix_agentd.conf Server=172.22.209.54 ServerActive=172.22.209.54 Hostname=DB22484 UserParameter=FromDual.MySQL.check,/usr/local/mpm/FromDualMySQLagent.pl /usr/local/mpm/zabbix_mpm.conf [root@ip bin]# cd /usr/bin/;ln -s /usr/local/zabbix/bin/zabbix_sender zabbix_sender [root@ip init.d]# service zabbix_agentd start Starting zabbix_agentd: /etc/init.d/functions: line 536: /usr/local/sbin/zabbix_agentd: 没有那个文件或目录 ##/path/zabbix-2.2.2/misc/init.d/fedora/core/zabbix_* 这个里面的zabbix_agentd别忘该路径 [root@ip path]# touch /path/FromDualMySQLagent.log [root@ip path]# chown -R zabbix:zabbix /path/zabbix/ ##zabbix_agentd启了以后看看日志，是否有报错，只要rc不等于0就是有问题
【定制监控项目】
触发器语法：http://www.cnblogs.com/jiangxu67/p/3990372.html
MySQL主从关系的结构中，从库每天有备份计划，添加一个备份计划结果和备份文件大小的监控
先创建一个模板，例如名称：MySQL.backup_status。把一台测试机加入到模板里面
建一个应用集：MySQL Backup
建一个监控项：MySQL Backup Status
存档以后，在已经添加该模板的主机上给zabbix_server发送测试数据：
[root@cobbler dumps]# zabbix_sender --zabbix-server 192.168.201.107 --port 10051 --host 'cobbler' --key MySQL.backup_status --value '1' ;echo $? info from server: "processed: 1; failed: 0; total: 1; seconds spent: 0.000034" sent: 1; skipped: 0; total: 1 0
从监控界面查看效果
添加触发器：
给zabbix_server发送测试数据：
[root@cobbler dumps]# zabbix_sender --zabbix-server 192.168.201.107 --port 10051 --host 'cobbler' --key MySQL.backup_status --value '0' ;echo $? info from server: "processed: 1; failed: 0; total: 1; seconds spent: 0.000027" sent: 1; skipped: 0; total: 1 0
查看效果，此时“类型”选项中选触发器也可以，如图2：
触发器的报警状态是闪烁的，在Zabbix WEB首页显示会更明显：
...弱弱的表示死锁的报警忽略，原因是那篇“MySQL锁和隔离级别浅析分析”测试时候导致的，显示绿色表示死锁问题已恢复。
回来继续说自制这个监控项，可以在主机MySQL定时备份计划部分脚本中多加一个备份结果判断，正常就执行上面zabbix_sender的命令把--value '1' 的状态发给zabbix_server反之发送个0，具体发什么定义什么自己定吧...上面例子和系统定义的返回码弄反了。
后期维护：
1、zabbix数据会慢慢增长，history和history_uint表的数据会很大，尤其是history_uint，可以根据下面网址的方法清理数据，也可以根据自身需要truncate这张表。
