Ubuntu下Cacti安装配置图文详解

没有评论

共计 14926 个字符,预计需要花费 38 分钟才能阅读完成。

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

参考:http://www.linuxidc.com/Linux/2014-10/107924.htm

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

iso.3.6.1.2.1.1.1.0 = STRING: “Linux ubuntu-server 3.5.0-23-generic #35~precise1-Ubuntu SMP Fri Jan 25 17:13:26 UTC 2013 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:
