• 安装LAMP    参考：lamp的安装及安全设置
  • 安装并配置net-snmp  参考:  centos配置net-snmp 
  • 下载CACTI源文件  Cacti for Linux/Unix
  • 解开源包、改权限，打补丁
  • 设置数据库，并导入数据
  • 设置crontab
  • 通过ui 进行必要的安装后设置

 

1、解开源包并打补丁

wget -P /root/tools/cacti/ http://www.cacti.net/downloads/cacti-0.8.7e.tar.gz
cd /usr/local/apache2/htdocs
tar zxvf /root/tools/cacti/cacti-0.8.7e.tar.gz
cd cacti-0.8.7e/
useradd cactiuser -s /sbin/nologin
chown -R cactiuser ./rra ./log
wget http://www.cacti.net/downloads/patches/0.8.7e/cli_add_graph.patch
wget http://www.cacti.net/downloads/patches/0.8.7e/snmp_invalid_response.patch
wget http://www.cacti.net/downloads/patches/0.8.7e/template_duplication.patch
patch -p1 -N < cli_add_graph.patch
patch -p1 -N < snmp_invalid_response.patch
patch -p1 -N < template_duplication.patch

2、创建并导入cacti的数据库

mysql -e 'create database cacti7e' -p
mysql cacti7e < /usr/local/apache2/htdocs/cacti-0.8.7e/cacti.sql  -p
mysql -e "grant all on cacti7e.* to cactiuser@localhost identified by 'cactiuser';" -p

3、更改 cacti-0.8.7e/include/config.php 相关数据库连接参数

$database_type = "mysql";
$database_default = "cacti7e";
$database_hostname = "localhost";
$database_username = "cactiuser";
$database_password = "cactiuser";

4、添加crontab 

echo  "*/1  * * * *  /usr/local/php/bin/php  /usr/local/apache2/htdocs/cacti-0.8.7e/poller.php" >/tmp/cron.tmp

crontab  -u cactiuser  /tmp/cron.tmp

5、用ie打开http://server ip/cacti-0.8.7e进入cacti的web安装界面

     1、用admin admin 登入后，修改ADMIN为你自己密码

    2、进入settings ->gernerl -web-Events 勾选所有项，如下：  

 

Web Events

  3、进入settings ->Poller ->Poller Interval 设置为一分钟，如下：

   4、进入settings ->visual ->Default RRDtool 1.2 Fonts 设置如下
