好了，到此lamp就安装完成了
3、安装net-snmp
[root@cacti ~]# yum install -y net-snmp net-snmp-utils 4、修改snmp的配置文件
[root@cacti ~]# cd /etc/snmp/
[root@cacti snmp]# cp snmpd.conf snmpd.conf.bak
[root@cacti snmp]# vim snmpd.conf
去掉末尾.1
#view systemview included .1.3.6.1.2.1.1
view systemview included .1.3.6.1.2.1
启动net-snmp，并测试net-snmp能够正常工作
[root@cacti ~]# service snmpd start
Starting snmpd: [ OK ]
[root@cacti ~]# snmpnetstat -v 2c -c public -Ca -Cp tcp localhost
Active Internet (tcp) Connections (including servers)
Proto Local Address Remote Address (state)
tcp *.ssh *.* LISTEN
tcp *.mysql *.* LISTEN
tcp localhost.smtp *.* LISTEN
tcp localhost.smux *.* LISTEN
tcp localhost.ssh localhost.53011 ESTABLISHED 5、安装RRDTool
[root@cacti ~]# yum install -y rrdtool
测试RRDTool能够正常工作
[root@cacti ~]# rrdtool -v

[root@cacti src]# tar xf cacti-0.8.8b.tar.gz -C /var/www/html/
[root@cacti src]# cd /var/www/html/
[root@cacti html]# ll
total 8
drwxr-xr-x. 13 1000 users 4096 Aug 6 2013 cacti-0.8.8b
[root@cacti html]# mv cacti-0.8.8b cacti
#创建cacti数据库，并导入cacti.sql到数据库中
[root@cacti ~]# cd /var/www/html/cacti/
[root@cacti cacti]# mysqladmin create cactidb
[root@cacti cacti]# ll cacti.sql #cacti源码包中自带的cacti数据库
-rw-r--r--. 1 1000 users 178349 Aug 6 2013 cacti.sql
[root@cacti cacti]# mysql cactidb < cacti.sql #导入自带的cacti数据库
#创建授权用户
[root@cacti ~]# mysql -e "GRANT ALL ON cactidb.* TO cactiuser@localhost IDENTIFIED BY 'cactiuser'"
[root@cacti ~]# mysqladmin flush-privileges
[root@cacti ~]# mysql -ucactiuser -pcactiuser

//$url_path = "/cacti/";
#下面我们来创建一个cacti用户（安装初始化cacti）并修改相关目录权限，
[root@cacti ~]# cd /var/www/html/cacti/
[root@cacti cacti]# useradd cactiuser
[root@cacti cacti]# chown -R cactiuser:cactiuser log/ rra/ 7、浏览器访问cacti
输入cacti服务器的地址http://192.168.0.104/cacti http://s3.运维网.com/wyfs02/M02/2F/4E/wKiom1OfDBaDglOAAAO6gB3cRlE242.jpg
点击【Next】 进行下一步安装 http://s3.运维网.com/wyfs02/M01/2F/4E/wKioL1OfDCuQ-10HAAHMUUCurS4194.jpg
选择【New Install】,点击【Next】进行下一步安装 http://s3.运维网.com/wyfs02/M01/2F/4E/wKiom1OfDIjAfgQOAATVFgK8s2A738.jpg
监测是否有权限错误，如果有，请修改对应目录的权限，然后点击【Finsh】，进行下一步 http://s3.运维网.com/wyfs02/M00/2F/4E/wKiom1OfDRaB-LhMAAF1mkalPkc890.jpg
输入账户和密码，默认都是admin，点击【Login】，进行下一步 http://s3.运维网.com/wyfs02/M00/2F/4E/wKioL1OfDRXiJBjkAAG0wZOkqGM922.jpg
系统提示：强制修改密码，然后平【Save】，进行下一步安装；进入cacti的首页面 http://s3.运维网.com/wyfs02/M02/2F/4E/wKiom1OfDcHxbI9MAAOxrLYeoZM809.jpg好了，到这里我们已经可以看cacti的配置界面了，下面我们就来详细的看一下。从上图中我们可以看到最上面有两个标签一个是红颜色的“console”控制台标签，另一个是“graphs”图像标签，下面我们点击一下“graphs”标签，如下图：
大家可以从图上看到，由于我们还没做任何配置，所以这里没有任何图像。好了，下面我们就来详细说一说这两个标签中内容。先说，console 标签。
大家先看左边这一栏，从图中我们可以看出，大致分为七个大项和多个项目。下面我们来的罗列一下，分别讲解。
(1).Create 创建
注，脚本只需要指定如何获取数据，并且获取到的数据经过处理后要按元宝输出。案例，
TAG：data TAG：data
input：30 output：40 好了，我们用脚本定义了收集数据方法，也指定了数据输出，那脚本多长时间执行一次呢？执行的时间是cacti程序设置的，下面我们来配置cacti安装的最重要的一步也是最后一步，设置cacti收集数据的默认的任务计划。这里任务计划是由poller.php程序执行的，需要说明的是poller.php是由php写的，单线程的功能相对较弱，为此cacti官方单独开发了一个多线程Spine工具，适合大规模监控应用。好了下面我们就来配置一下任务计划并查看。
[root@cacti ~]# echo '*/5 * * * * /usr/bin/php /var/www/html/cacti/poller.php &>/dev/null' > /var/spool/cron/cactiuser
[root@cacti ~]# crontab -u cactiuser -l
*/5 * * * * /usr/bin/php /var/www/html/cacti/poller.php &>/dev/null 为了防止这个任务计划不执行，我们最好手动验证一下
[root@cacti ~]# su cactiuser
[cactiuser@cacti root]$ /usr/bin/php /var/www/html/cacti/poller.php

[root@cacti ~]# vim /etc/php.ini
[Date]
; Defines the default timezone used by the date functions
; http://www.php.net/manual/en/datetime.configuration.php#ini.date.timezone
;date.timezone =
date.timezone = Asia/Shanghai
[root@cacti ~]# service httpd restart
Stopping httpd: [ OK ]
Starting httpd: [ OK ] 接下来我们再来测试一下
[cactiuser@cacti root]$ /usr/bin/php /var/www/html/cacti/poller.php
#查看一下cacti输出日志
[cactiuser@cacti root]$ cd /var/www/html/cacti/log

首先我们点击一下“Devices”标签，出下以下界面，大家从图中可以看出，默认的主机就是Localhost。 http://s3.运维网.com/wyfs02/M01/2F/4E/wKiom1OfFLSAzPQuAALzofzW608100.jpg http://s3.运维网.com/wyfs02/M00/2F/4E/wKioL1OfFJfx7peIAAQP2AKp9N8529.jpg
接下来我们点击一下“Localhost”主机，出现以下界面。 http://s3.运维网.com/wyfs02/M02/2F/4E/wKiom1OfFOGT-C5yAAUm27XnNwg456.jpg
上图是默认的配置，我们只要修改一处即可，便是“SNMP Options”。如下图http://s3.运维网.com/wyfs02/M01/2F/4E/wKioL1OfFL3jBscmAAYkABNW3Mc425.jpg
接下来我们选择右上脚的“Create Graphs for this Host”（为这个主机增加监控图形）， http://s3.运维网.com/wyfs02/M00/2F/4E/wKiom1OfFTqw1DNdAAVI5tZQmAE872.jpg
我们选择监控本地主机的磁盘空间，点击“Create”即可。下面我们来点击最上面的“Graph”标签 。如下图，
