在开始操作之前,先简单介绍几个概念
*SNMP :简单网络管理协议
它主要是根据用户的需求获取远程被监控主机的一些信息而已,
*RRDTOOL : 是一个强大的绘图工具
它主要是根据用户的需求将从SNMP协议(当然也可以是其他的方式,比如说sheel脚本等,)获取到信息,绘制成图像,
是一个基于PHP开发的强大的检测分析工具而已,cacti主要是通过SNMP或sheel脚本等方式获取到被监控主机的数据, 然后通过rrdtool存储更新数据,当用户需要查看数据的时候,使用rrdtool生成图表通过cacai展示给用户,
****************************************************************************************
下面将在一台默认安装有rhel5.8的系统上安装配置cacti
****************************************************************************************
上面说过cacit是一个php语言开发的网页工具,那么我们需要安装LAMP平台,还要生成图像展示给用户,需要安装rrdtool,如果要使用snmp协议监控其他主机或本机,需要安装snmp
****************************************************************************************
准备以下软件包,存放至/usr/src目录下
****************************************************************************************
apr-1.4.6.tar.bz2apr-util-1.4.1.tar.bz2
cmake-2.8.8.tar.gz 这些包主要是LAMP环境所用到的软件包
httpd-2.4.2.tar.bz2
mysql-5.5.25a.tar.gz
php-5.4.4.tar.bz2
****************************************************************************************
rrdtool-1.4.7.tar.gz
cacti-spine-0.8.8a.tar.gz
cacti-0.8.8a.tar.gz
****************************************************************************************
准备完成好,下面来安装配置了,需要注意的是软件包一定要放到/usr/src目录,而且要配置好yum源,
一, 构建LAMP环境,这里使用脚本自动化编译安装并配置,(当然也可以使用yum安装,)
1. 构建LAMP平台,脚本内容如下#!/bin/bash # andy_f # 编译安装LAMP平台 local_ip=`ifconfig eth0 | grep "inet addr" | awk -F: '{print $2}' | awk '{print $1}'` # install path http_path=/usr/local/apache apr_path=/usr/local/apr apr_util_path=/usr/local/apr-util php_path=/usr/local/php mysql_path=/usr/local/mysql re=0 # install package name apr="apr-1.4.6.tar.bz2" apr_util="apr-util-1.4.1.tar.bz2" http="httpd-2.4.2.tar.bz2" php="php-5.4.4.tar.bz2" cmake="cmake-2.8.8.tar.gz" mysql="mysql-5.5.25a.tar.gz"

执行此脚本即可, 如果不想使用脚本安装的话,可以参考 不过需要注意的是在编译安装php的时候需要加 --enable-sockets 参数,
