选择new install
安装spine
tar xzvf cacti-spine-0.8.7a.tar.gz cd cacti-spine-0.8.7a
编译需要libtool
rpm -ivh imake-1.0.2-3.i386.rpm rpm -ivh autoconf-2.59-12.noarch.rpm rpm -ivh automake-1.9.6-2.1.noarch.rpm rpm -ivh libtool-1.5.22-6.1.i386.rpm rpm -ivh libtool-ltdl-1.5.22-6.1.i386.rpm rpm -ivh libtool-ltdl-devel-1.5.22-6.1.i386.rpm ./configure make
把spine 和spine.conf copy到/usr/local/spine
mkdir /usr/local/spine cp spine spine.conf /usr/local/spine
编辑 spine.conf 文件，输入数据库名、数据库用户名和密码等信息.
指定spine的物理路径
Console -> Configuration -> Settings -> Paths -> Alternate Poller Path -> Spine Poller File Path
路径为/usr/local/spine/spine
Cacti Plugins
Cacti插件是对cacti的扩展。
要使用cacti插件必须先扩展cacti架构，来支持插件。
安装cacti插件架构扩展
下载地址：http://cactiusers.org/downloads/
1）.解压下载的tar包，你会得到一个cacti-plugin-arch目录
# tar –zxvf cacti-plugin-arch.tar.gz # cd cacti-plugin-arch # ls
2）.安装插件扩展
cp cacti-plugin-0.8.7b-PA-v2.1.diff /usr/local/cacti
//备份cacti目录，以备插件扩展安装失败后能恢复到原状态
cd /usr/local cp –r cacti ./cacti.bak cd ./cacti
//首先使用以下命令进行测试
# patch -p1 -N --dry-run < cacti-plugin-0.8.7b-PA-v2.1.diff
//以上命令成功后，使用以下命令进行安装
# patch -p1 -N < cacti-plugin-0.8.7b-PA-v2.1.diff
将pa.sql导入数据库，支持Plugin Management
mysql --user=root --password=123456 cacti < pa.sql
3）.安装后配置，首先查看你的cacti配置文件，看cacti相关的数据库信息是否被覆盖，如果被覆盖请直接从备份中拷贝一份到配置文件目录。
# cp ../include/config.php ./include/config.php
4）.修改global.php以正常访问cacti
vi /usr/local/cacti/include/global.php
将$config['url_path'] = “/”;修改为$config['url_path'] = “/cacti/”;
注：如果cacti安装在 /var/www/html下则不用修改global.php
安装插件 下载地址为：http://cactiusers.org/downloads/
安装Monitor
tar xzvf monitor-0.8.2.tar.gz mv monitor /usr/local/cacti/plugins/
安装插件，只需要将插件目录拷贝到cacti/plugins/目录下即可。如果是升级安装，只需要完全覆盖原插件目录即可。
vi /usr/local/cacti/include/global.php
在配置中查找$plugins = array();行，在此行下面加入：
$plugins[] = 'monitor';
注意：上面monitor的名字必须与cacti/plugins/目录下插件目录的名字相同。
在console选项卡下，点击左侧菜单中的Settings链接，在右侧出现的web页中点击Misc选项卡来配置Monitor插件。
在console - User Management – admin – 在View Monitoring前打勾
安装thold
tar xzvf thold-0.3.9.tar.gz mv thold /usr/local/cacti/plugins/ tar xzvf settings-0.5.tar.gz mv settings /usr/local/cacti/plugins/ vi /usr/local/cacti/include/global.php $plugins[] = ' thold '; $plugins[] = ' settings ';
在console – settings里修改thold相关属性
注：thold要和settings一起安装才能使用
用thold插件监控硬盘实现报警功能
适用版本cacti 0.8.7b
在cacti目录下，vi global_arrays.php
搜索custom_data_source_types，修改这一段如下：
$custom_data_source_types = array( "CURRENT_DATA_SOURCE" => "Current Graph Item Data Source", "ALL_DATA_SOURCES_NODUPS" => "All Data Sources (Don't Include Duplicates)", "ALL_DATA_SOURCES_DUPS" => "All Data Sources (Include Duplicates)", "SIMILAR_DATA_SOURCES_NODUPS" => "All Similar Data Sources (Don't Include Duplicates)", "SIMILAR_DATA_SOURCES_DUPS" => "All Similar Data Sources (Include Duplicates)", "CURRENT_DS_MINIMUM_VALUE" => "Current Data Source Item: Minimum Value", "CURRENT_DS_MAXIMUM_VALUE" => "Current Data Source Item: Maximum Value", "CURRENT_GRAPH_MINIMUM_VALUE" => "Graph: Lower Limit", "CURRENT_GRAPH_MAXIMUM_VALUE" => "Graph: Upper Limit", "VALUE_OF_HDD_TOTAL" => "Value of hdd_total data source");
在cacti界面的Graph Management-cdefs新建cdef模块，名字自己起，添加字段如下：
Item #1 Special Data Source: CURRENT_DATA_SOURCE Item #2 Custom String: 100 Item #3 Operator: * Item #4 Special Data Source: VALUE_OF_HDD_TOTAL Item #5 Operator: /
这样就可以在Threshold Templates里面添加监控硬盘的模块了，我添加的是Host MIB - Hard Drive Space ，最后在Threshold CDEF里面选择刚自定义的cdef，这样就可以正常监控硬盘使用率了。
安装realtime
tar xzvf realtime-0.32.tar.gz mv realtime /usr/local/cacti/plugins/ vi /usr/local/cacti/include/global.php $plugins[] = ' realtime '; mkdir /usr/local/cacti/rcache chmod a+wx /usr/local/cacti/rcache
在console – settings – Misc 里修改Cache Directory的路径为/usr/local/cacti/rcache
如果安装0.34版则需要修改
1. poller_rt.php #if (file_exists("./include/global.php")) { # include("./include/global.php"); #} else { # include("./include/config.php"); #} include(dirname(__FILE__) . "/../../include/global.php"); #include_once($config["base_path"] . "/lib/poller.php"); #include_once($config["base_path"] . "/lib/data_query.php"); #include_once($config["base_path"] . "/lib/graph_export.php"); #include_once($config["base_path"] . "/lib/rrd.php"); include_once($config["library_path"] . "/poller.php"); include_once($config["library_path"] . "/data_query.php"); include_once($config["library_path"] . "/graph_export.php"); include_once($config["library_path"] . "/rrd.php");
2. cmd_rt.php
# include("./include/global.php"); #} else { # include("./include/config.php"); #} include(dirname(__FILE__) . "/../../include/global.php"); #include_once($config["base_path"] . "/lib/snmp.php"); #include_once($config["base_path"] . "/lib/poller.php"); #include_once($config["base_path"] . "/lib/rrd.php"); #include_once($config["base_path"] . "/lib/ping.php"); include_once($config["library_path"] . "/snmp.php"); include_once($config["library_path"] . "/poller.php"); include_once($config["library_path"] . "/rrd.php"); include_once($config["library_path"] . "/ping.php");
安装syslog
需要的软件syslog-ng 、eventlog 、libol
1. 安装syslog-ng
tar xzvf eventlog-0.2.7.tar.gz cd eventlog-0.2.7 ./configure --prefix=/usr/local/eventlog make make install cd .. tar xzvf libol-0.3.18.tar.gz cd libol-0.3.18 ./configure --prefix=/usr/local/eventlog/libol make make install cd .. tar xzvf syslog-ng-2.0.9.tar.gz cd syslog-ng-2.0.9 export PKG_CONFIG_PATH=/usr/local/eventlog/lib/pkgconfig/ ./configure --prefix=/usr/local/syslog-ng make make install mkdir /usr/local/syslog-ng/etc/ cp doc/examples/syslog-ng.conf.sample /usr/local/syslog-ng/etc/syslog-ng.conf
修改syslog-ng.conf文件如下：
需要执行的bash文件如下：（脚本文件放在/usr/local/syslog-ng/sbin下）
安装cacti插件syslog
tar xzvf syslog-0.5.2.tar.gz mv syslog-0.5.2 /usr/local/cacti/plugins/syslog vi /usr/local/cacti/include/global.php $plugins[] = ' syslog ';
将syslog的表导入数据库
mysql –u root –p use cacti; source /usr/local/cacti/plugins/syslog/syslog.sql
停止系统自带的syslog
pkill -9 syslog
启动syslog-ng
/usr/local/syslog-ng/sbin/syslog-ng
启动bash脚本
nohup /usr/local/syslog-ng/sbin/syslog2mysql.sh
安装advanced ping
0.8.7b本身带有ss_fping.php，需要加入一行
vi /usr/local/cacti/scripts/ss_fping.php include_once(dirname(__FILE__) . "/../include/global_settings.php");
然后将xml模板导入到Graph Templates即可使用
NTOP
rpm -ivh libpcap-devel-0.9.4-11.el5.i386.rpm tar xzvf ntop-3.3.6.tar.gz cd ntop ./autogen.sh ./configure --prefix=/usr/local/ntop --with-rrd-home=/ make make install useradd ntop passwd ntop chown -R ntop.ntop /usr/local/ntop/share/ntop/ cp packages/RedHat/ntop.conf.sample /usr/local/ntop/etc/ntop/ntop.conf /usr/local/ntop/bin/ntop -P /usr/local/ntop/share/ntop -u ntop –A vi /usr/local/ntop/etc/ntop/ntop.conf
#程序运行用户

#监控的网卡
–interface eth0
–trace-level 3
#web访问的端口
–http-server 3000
–disable-schedyield
启动ntop服务，指定读取的配置文件，只监控192.168.1.0/24网段
/usr/local/ntop/bin/ntop @/usr/local/ntop/etc/ntop/ntop.conf -m 192.168.1.0/24
设置开机自启动
vi /etc/rc.local /usr/local/ntop/bin/ntop @/usr/local/ntop/etc/ntop/ntop.conf –m 192.168.1.0/24
Nagios
useradd nagios passwd nagios groupadd nagcmd usermod -G nagcmd nagios usermod -G nagcmd apache cd /home/test/ tar xzvf nagios-3.0b6.tar.gz cd nagios-3.0b6 ./configure --prefix=/usr/local/nagios --with-gd-lib=/usr/lib --with-gd-inc=/usr/include make all make install make install-init make install-config make install-commandmode make install-webconf htpasswd -c /usr/local/nagios/etc/htpasswd.users nagios service httpd restart cd .. tar xzvf nagios-plugins-1.4.12.tar.gz cd nagios-plugins-1.4.12 ./configure --with-nagios-user=nagios --with-nagios-group=nagios make make install chkconfig --add nagios chkconfig nagios on /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg If there are no errors, start Nagios. service nagios start vi /usr/local/nagios/etc/cgi.cfg
将默认的nagiosadmin修改为nagios
一开始会提示“HTTP WARNING: HTTP/1.1 403 Forbidden ”是因为nagios监控/var/www/html/下面的index.html文件，若没有就会提示错误，创建一个文件即可！
vi /var/www/html/index.html
