系统和需要手动安装的软件包，其它需要的软件包以YUM方式安装

CentOS5.5

rrdtool-1.4.4.tar.gz

cacti-spine-0.8.7g.tar.gz

cacti-0.8.7g.tar.gz

net-snmp-5.6.tar.gz

1.安装LMAP环境
#yum install httpd mysql-server php php-devel php-mysql

2.下载cacti,Spine,rrdtool,net-snmp 到如下目录
#mkdir cacti-install

3.安装Spine所需要的包（包括net-snmp-devel ，后续手动安装）

#yum install mysql mysql-devel openssl-devel

4.安装RRDTool所需要的包
#yum install cairo-devel libxml2-devel pango-devel pango libpng-devel freetype freetype-devel libart_lgpl-devel

5.安装cacti所需要的包(net-snmp)

# tar -zxvf net-snmp-5.6.tar.gz
# cd net-snmp-5.6
# ./configure --prefix=/usr/local/net-snmp --enable-developer(--enable-developer 是spine所需要的）
# make && make install
#/usr/local/net-snmp/sbin/snmpd （启动）

#vi /etc/rc.d/rc.local加入自启动
/usr/local/net-snmp/sbin/snmpd

6.安装rrdtool
#tar -zxvf rrdtool-1.4.4.tar.gz
# cd rrdtool-1.4.4
# ./configure --prefix=/usr/local/rrdtool
# make && make install

7.安装cacti
# groupadd cacti
# useradd -g cacti cacti
# tar -zxvf cacti-0.8.7g.tar.gz
# mv cacti-0.8.7g /var/www/html/cacti

8.配置数据库
# mysqladmin -u root password mingdaoit
# mysql -u root -p
输入密码
mysql> create database cacti;
mysql> grant all on cacti.* to cacti@localhost identified by 'abc123';
mysql> flush privileges;
mysql> /q
# cd /var/www/html/cacti/
# mysql -ucacti -pabc123 cacti<cacti.sql

# vi /var/www/html/cacti/include/config.php

/* make sure these values refect your actual database/host/user/password */
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cacti";
$database_password = "abc123";
$database_port = "3306";

9.配置cacti

http://192.168.15.125/cacti
注意rrdtool路径,修改为实际路径
#rpm -ql rrdtool

cacti默认是使用cmd.php采集数据，如果不使用spine,这样也就基本上可以了

手工为监控对象生产文件
# /usr/bin/php /var/www/html/cacti/poller.php

[root@nagios etc]# cd /var/www/html/cacti/rra
[root@nagios rra]# ls
localhost_load_1min_5.rrd localhost_mem_swap_4.rrd localhost_users_6.rrd
localhost_mem_buffers_3.rrd localhost_proc_7.rrd

# vi /etc/crontab加入如下，每五分钟更新一次

*/5 * * * * cacti /usr/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&1

10.安装cacti-spine
# tar -zxvf cacti-spine-0.8.7g.tar.gz
# cd cacti-spine-0.8.7g
# ./configure --prefix=/usr/local/cacti-spine --wiht-snmp=/usr/local/net-snmp
# make && make install
# cd /usr/local/cacti-spine/etc
# cp spine.conf.dist spine.conf
# vi spine.conf

DB_Host         localhost
DB_Database     cacti
DB_User         cacti
DB_Pass         abc123
DB_Port         3306
DB_PreG         0

在Console----setting---paths 下设置spine的路径

在Console----setting---general 下选择所安装的rrdtool的版本

在Console----setting---poller 下选择poller type为spine

11.安装cacti-plugin

# tar -zxvf cacti-plugin-0.8.7g-PA-v2.8.tar.gz
# cd cacti-plugin-arch/
# cp cacti-plugin-0.8.7g-PA-v2.8.diff /var/www/html/cacti/
# cp pa.sql /var/www/html/cacti/
# cd /var/www/html/cacti
# patch -p1 -N < cacti-plugin-0.8.7g-PA-v2.8.diff (这个必须是在cacti目录下执行)
# mysql -ucacti -pabc123 cacti < pa.sql

#vi include/global.php

/* Default database settings*/
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cacti";
$database_password = "abc123";
$database_port = "3306";

#vi include/config.php
$url_path="/cacti/"

12.安装相关插件

解压相关你要安装的插件然后mv到/var/www/html/cacti/plugins目录下。

修改user managemnet下admin的相关权限，及把未打钩的钩上
