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

enadmin@ubuntu-server:~$
查看 localhost 的监控画面
在配置完毕上述内容以后，正常情况下应该可以看到 cacti 对于自身 localhost 的的默认监控了。我们进入到 Graphs->Tree Mode->Default Tree->Host:Localhost 当中查看对于 localhost 的监控，如下图所示。
常见问题解决
问题 1：cacti 无法正常生成图片
在 cacti 当中看不到图片，通过 Turn Off Graph Debug Mode. 提示报错如下：
‘/var/lib/cacti/rra/localhost_users_6.rrd’: No such file or directory
解决方法：
这是因为权限问题原因导致的，系统无法生成相应的 rrd 文件，需要我们人工手动生成，具体操作方法如下：
Console->System Utilities->Rebuild Poller Cache
