Cacti工具是一套开源的基于Web的网络监控和系统监控的图形解决方案。Cacti通过SNMP服务获取数据，并使用RRDtool绘制图形，提供非常直观的数据和用户管理功能。Cacti需要Web、MySQL和PHP的支持。Cacti一般用于监控网络流量、CPU负载、磁盘空间等。

4、导入Cacti数据库文件
[root@sh ~]# mysql -uroot -p cacti < /var/www/html/cacti/cacti.sql
5、修改Cacti相关的MySQL数据库配置文件

|
[root@sh ~]
# vim /var/www/html/cacti/include/config.php

/*
make
sure these values refect your actual database

*/
$database_type =
"mysql"
;
$database_default =
"cacti"
;
$database_hostname =
"localhost"
;
$database_username =
"cacti"
;
$database_password =
"cactipass"
;
$database_port =
"3306"
;
$database_ssl =
false
;
|
6、添加防火墙规则允许外部访问80端口

[root@sh ~]
# iptables -A INPUT -p udp --dport 80 -j ACCEPT
[root@sh ~]
# iptables -A INPUT -p tcp --dport 80 -j ACCEPT
[root@sh ~]
# service iptables save
|
7、配置Cacti虚拟主机文件，创建/etc/httpd/conf.d/cacti.conf，允许192.168.1.0的网段访问

[root@sh ~]
# vim /etc/httpd/conf.d/cacti.conf
Alias

/var/www/html/cacti/
>
Order Deny,Allow
Deny from all
Allow from 192.168.1.0
/24
<
/Directory

|
8、调整系统时间，并且修改php.ini对应的时区为'Asia/Shanghai'
|

[root@sh ~]
# ntpdate time.nist.gov
[root@sh ~]
# hwclock ；写入BIOS
#添加时间自动同步计划任务

/usr/sbin/ntpdate
time
.nist.gov;hwclock -w
|
|

|
[root@sh ~]
# vim /etc/php.ini
date
.timezone =
'Asia/Shanghai'
|
9、配置cacti轮询php脚本，添加cron计划任务，让它每五分钟执行一次以生成图像显示
|

11、浏览器登录http://IP/cacti/install/完成安装向导
Cacti默认登录用户和密码都是admin，根据提示修改，进入Cacti的Web界面
安装完成
三、安装Cacti加速轮询器Spine
1、下载spine-0.8.8f，版本对应cacti的版本
[root@sh ~]# wget http://www.cacti.net/downloads/spine/cacti-spine-0.8.8f.tar.gz
2、安装Spine依赖的包
[root@sh ~]# yum -y install libtool net-snmp-devel mysql-devel
3、编译安装Spine

.8.8f'
|
|

|
[root@sh cacti-spine-0.8.8f]
# ls /usr/local/spine/
bin etc
|
4、配置spine.conf文件，指定cacti数据库、用户和密码
[root@sh ~]# cp /usr/local/spine/etc/spine.conf.dist /etc/spine.conf
[root@sh ~]# vim /etc/spine.conf
5、执行Spine轮询脚本获取监测主机信息
|

|
[root@sh ~]
# /usr/local/spine/bin/spine
SPINE: Using spine config
file
[
/etc/spine
.conf]
SPINE: Version 0.8.8f starting
SPINE: Time: 0.2636 s, Threads: 5, Hosts: 2
|
6、在Cacti页面选择Spine为默认轮询方式
console--->Settings--->Paths--->Spine Poller File Path--->/usr/local/spine/bin/spine--->save
Poller--->Poller Type--->spine--->save
Cacti配置完成
