前言：

原本是想源码安装的，但是现在发现还是太麻烦了，就直接通过apt-get install安装了。

一、cacti概述

1. cacti是用php语言实现的一个软件，它的主要功能是用snmp服务获取数据，然后用rrdtool储存和更新数据，当用户需要查看数据的时候用rrdtool生成图表呈现给用户。因此，snmp和rrdtool是cacti的关键。Snmp关系着数据的收集，rrdtool关系着数据存储和图表的生成。

2. Mysql配合PHP程序存储一些变量数据并对变量数据进行调用，如：主机名、主机ip、snmp团体名、端口号、模板信息等变量。

3. snmp抓到数据不是存储在mysql中，而是存在rrdtool生成的rrd文件中（在cacti根目录的rra文件夹下）。rrdtool对数据的更新和存储就是对rrd文件的处理，rrd文件是大小固定的档案文件（Round Robin Archive），它能够存储的数据笔数在创建时就已经定义。

二、系统环境

1、Linux ubuntu-server 3.5.0-23-generic x86_64

三、apache、mysql、php安装

四、cacti安装

enadmin@ubuntu-server:~$ apt-get update

enadmin@ubuntu-server:~$ sudo apt-get install cacti

通过这种方式安装会显示依赖包
