所需的包:cacti-0.8.7h.tar.gz cacti-spine-0.8.7h.tar.gz cacti-plugin-0.8.7h-PA-v3.0.tar.gz settings-v0.71-1.tgz monitor-v1.3-1.tgz nagios-cn-3.2.3.tar.bz2 nagios-plugins-1.4.16.tar.gz gd-devel-2.0.35-10.el6.x86_64.rpm FCGI-0.74.tar.gz FCsettings-v0.71-1.tgzGI-ProcManager-0.24.tar.gz ExtUtils-Constant-0.23.tar.gz Socket-2.001.tar.gz fastcgi-wrapper.pl rrdtool-perl-1.3.8-6.el6.x86_64.rpm fetion linuxso_20101113.tar.gz nrpe-2.14.tar.gz ganglia-3.4.0.tar.gz ganglia-web-3.5.2.tar.gz libconfuse-2.6-3.el6.x86_64.rpm libconfuse-devel-2.6-3.el6.x86_64.rpm rrdtool-devel-1.3.8-6.el6.x86_64.rpm npc-2.0.4.tar.gz ndoutils-1.4b9.tar.gz PDO_MYSQL-1.0.2.tgz
1.安装与配置cacti
[root@server17 kernel]# tar zxf cacti-0.8.7h.tar.gz -C /usr/local/lnmp/nginx/html/
[root@server17 kernel]# cd /usr/local/lnmp/nginx/html/
[root@server17 html]# mv cacti-0.8.7h/ cacti
[root@server17 cacti]# yum install rrdtool -y
[root@server17 cacti]# vim /usr/local/lnmp/nginx/conf/nginx.conf
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
include fastcgi.conf;
}
[root@server17 cacti]# nginx -s reload
[root@server17 cacti]# /etc/init.d/mysqld start
[root@server17 cacti]# /etc/init.d/php-fpm start
[root@server17 cacti]# mysql
mysql> create database cacti;
mysql> quit
[root@server17 cacti]# mysql cacti < cacti.sql
[root@server17 cacti]# mysql
mysql> grant all on cacti.* to cacti@localhost identified by 'cacti';
mysql> flush privileges;
mysql> quit
[root@server17 cacti]# cd /usr/local/lnmp/nginx/html/cacti/include/
[root@server17 include]# vim config.php
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cacti";
$database_password = "cacti";
$database_port = "3306";
$database_ssl = false;
[root@server17 include]# nginx -s reload
访问server17.example.com/cacti出现如下页面：
解决方法如下：
[root@server17 include]# yum list net-snmp*
[root@server17 include]# yum install net-snmp.x86_64 net-snmp-utils.x86_64 net-snmp-perl.x86_64 net-snmp-python.x86_64 -y
按下一步会出现白屏,解决方法如下:
[root@server17 include]# vim /usr/local/lnmp/nginx/html/cacti/lib/functions.php
function kill_session_var($var_name) {
/* register_global = off: reset local settings cache so the user sees the new settings */
unset($_session_unregister[$var_name]);
/* register_global = on: reset local settings cache so the user sees the new settings */
unset($_SESSION[$var_name]);
}
[root@server17 include]# useradd cacti
[root@server17 include]# chown cacti /usr/local/lnmp/nginx/html/cacti/rra/ -R
[root@server17 include]# chown cacti /usr/local/lnmp/nginx/html/cacti/log/ -R
[root@server17 include]# su - cacti
[cacti@server17 ~]$ crontab -e
*/5 * * * * /usr/local/lnmp/php/bin/php /usr/local/lnmp/nginx/html/cacti/poller.php
[cacti@server17 etc]$ logout
[root@server17 include]# /etc/init.d/crond start
[root@server17 include]# vim /etc/snmp/snmpd.conf
(注:以下配置可在http://www.cyberciti.biz/nixcraft/linux/docs/uniqlinuxfeatures/mrtg/上查看)

[root@server17 include]# /etc/init.d/snmpd start
[root@server17 include]# snmpwalk -v 1 -c public localhost IP-MIB::ipAdEntIfIndex (此命令可在http://www.cyberciti.biz/nixcraft/linux/docs/uniqlinuxfeatures/mrtg/上查看)
IP-MIB::ipAdEntIfIndex.127.0.0.1 = INTEGER: 1
IP-MIB::ipAdEntIfIndex.192.168.122.117 = INTEGER: 2
(出现类似上面的输出为正常)
访问server17.example.com/cacti出现如下页面:
注:第一次登录会强制要求更改密码(初始用户名:admin,密码:admin)
出现类似上面图形说明可以正常采集到数据.
#安装插件
[root@server17 kernel]# tar zxf cacti-plugin-0.8.7h-PA-v3.0.tar.gz
[root@server17 kernel]# cd cacti-plugin-arch/
[root@server17 cacti-plugin-arch]# mysql cacti < pa.sql
[root@server17 cacti-plugin-arch]# cp cacti-plugin-0.8.7h-PA-v3.0.diff /usr/local/lnmp/nginx/html/cacti/
[root@server17 cacti]# yum install patch -y
[root@server17 cacti]# patch -p1 -N < cacti-plugin-0.8.7h-PA-v3.0.diff
[root@server17 cacti]# cd include/
[root@server17 include]# vim config.php
$cacti_session_name = "Cacti";
$url_path = "/cacti/";
[root@server17 kernel]# tar zxf settings-v0.71-1.tgz -C /usr/local/lnmp/nginx/html/cacti/plugins
[root@server17 kernel]# tar zxf monitor-v1.3-1.tgz -C /usr/local/lnmp/nginx/html/cacti/plugins
选择User Management
将Plugin Management打上对勾,按save保存.
在Configuration中就会出现Plugin Management这个选项,启动插件.
注：在新版的cacti中已经集成了Plugin Management这个功能，只需将要安装的插件包加压到cacti目录下的plugins目录中，然后在Plugin Management中安装激活即可使用
#安装并配置spine
[root@server17 ~]# yum install net-snmp-devel mysql-devel openssl-devel dos2unix autoconf automake binutils libtool gcc cpp glibc-headers kernel-headers glibc-devel -y
[root@server17 kernel]# tar zxf cacti-spine-0.8.7h.tar.gz
[root@server17 kernel]# cd cacti-spine-0.8.7h
[root@server17 cacti-spine-0.8.7h]# ./bootstrap
[root@server17 cacti-spine-0.8.7h]# ./configure --with-snmp=/usr/ --with-mysql=/usr/local/lnmp/mysql/
[root@server17 cacti-spine-0.8.7h]# make && make install
[root@server17 cacti-spine-0.8.7h]# cd /usr/local/spine/etc/
[root@server17 etc]# cp spine.conf.dist /etc/spine.conf
[root@server17 etc]# vim /etc/spine.conf
DB_Host localhost
DB_Database cacti
DB_User cacti
DB_Pass cacti
DB_Port 3306
DB_PreG 1
(注:如果你用的是cacti087g,将DB_PreG配置为0,否则将 DB_PreG配置为1.)
[root@server17 etc]# /usr/local/spine/bin/spine
此时会出现以下错误:
/usr/local/spine/bin/spine: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No such file or directory
解决方法如下:
[root@server17 etc]# vim /etc/ld.so.conf
include ld.so.conf.d/*.conf
/usr/local/lnmp/mysql/lib
[root@server17 etc]# ldconfig
执行/usr/local/spine/bin/spine出现类似如下结果为正确：
SPINE: Using spine config file [/etc/spine.conf]
SPINE: Version 0.8.7h starting
SPINE: Time: 0.1010 s, Threads: 5, Hosts: 2
选择Settings选项.
选择Paths选项.
如图填写并保存,然后选择Poller选项.
如图选择并保存.
注：观察图像，如果没有出现中断说明spine配置成功.
#监控远程主机(server85.example.com)
以下步骤在server85上实施：
[root@server85 ~]# yum install net-snmp-5.5-41.el6.x86_64 -y
[root@server85 ~]# yum install net-snmp-utils-5.5-41.el6.x86_64 -y
[root@server85 ~]# vim /etc/snmp/snmpd.conf
(注:以下配置可在http://www.cyberciti.biz/nixcraft/linux/docs/uniqlinuxfeatures/mrtg/上查看)
#com2sec notConfigUser default public
com2sec local localhost public
com2sec mynetwork 192.168.122.0/24 public

[root@server85 ~]# /etc/init.d/snmpd start
[root@server85 ~]# snmpwalk -v 1 -c public localhost IP-MIB::ipAdEntIfIndex(此命令可在http://www.cyberciti.biz/nixcraft/linux/docs/uniqlinuxfeatures/mrtg/上查看)
IP-MIB::ipAdEntIfIndex.127.0.0.1 = INTEGER: 1
IP-MIB::ipAdEntIfIndex.192.168.122.185 = INTEGER: 2
注：出现类似上面输出,说明配置完成.
以下步骤在server17上实施：
[root@server17 ~]# yum install net-snmp-5.5-41.el6.x86_64 -y
[root@server17 ~]# yum install net-snmp-utils-5.5-41.el6.x86_64 -y
[root@server17 ~]# vim /etc/snmp/snmpd.conf
(注:以下配置可在http://www.cyberciti.biz/nixcraft/linux/docs/uniqlinuxfeatures/mrtg/上查看)
#com2sec notConfigUser default public
com2sec local localhost public
com2sec mynetwork 192.168.122.0/24 public
#group notConfigGroup v1 notConfigUser
#group notConfigGroup v2c notConfigUser
group MyRWGroup v1 local
group MyRWGroup v2c local
group MyRWGroup usm local

[root@server17 ~]# /etc/init.d/snmpd start
[root@server17 ~]# snmpwalk -v 1 -c public 192.168.122.185 IP-MIB::ipAdEntIfIndex(此命令可在http://www.cyberciti.biz/nixcraft/linux/docs/uniqlinuxfeatures/mrtg/上查看)
IP-MIB::ipAdEntIfIndex.127.0.0.1 = INTEGER: 1
IP-MIB::ipAdEntIfIndex.192.168.122.185 = INTEGER: 2
选择Devices选项，并选择add设备.
如上图填写并保存.
注：如果需要监控root分区的剩余空间，需要将/etc/snmp/snmpd.conf中的disk / 1000这一行的注释去掉，这样在创建图时才有相应的选项，否则无法监控。
选择所要创建的图.
将新添加的设备加入到树中.
至此cacti的安装及配置完毕！！！
2.安装与配置nagios
[root@server17 kernel]# useradd nagios
[root@server17 kernel]# usermod -G nagios nginx(注：通过web更改nagios设置时，需要考虑此权限问题，例如：启动服务通知时)
[root@server17 kernel]# yum localinstall gd-devel-2.0.35-10.el6.x86_64.rpm -y
[root@server17 kernel]# tar jxf nagios-cn-3.2.3.tar.bz2
[root@server17 kernel]# cd nagios-cn-3.2.3
[root@server17 nagios-cn-3.2.3]# ./configure –enable-embedded-perl
此时会出现如下提示:
Can't locate ExtUtils/Embed.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .).

[root@server17 kernel]# nginx -s reload
访问nagios.westos.org并登录（用户名为nagiosadmin）,出现如下页面为成功.（注:记得IP和域名的解析）
此时如果访问拓扑图在终端中会出现以下报错:
