介绍php

Cacti是一套基于PHP,MySQL,SNMP及RRDTool开发的网络流量监测图形分析工具。Cacti是经过 snmpget来获取数据，使用 RRDtool绘画图形。它提供了很是强大的数据和用户管理功能，能够指定每个用户能查看树状结构、host以及任何一张图，还能够与LDAP结合进行用户验证，同时也能本身增长模板，功能很是强大完善。界面友好。软件 Cacti 的发展是基于让 RRDTool 使用者更方便使用该软件，除了基本的 Snmp 流量跟系统资讯监控外，Cacti 也可外挂 Scripts 及加上 Templates 来做出各式各样的监控图。

snmp关系着数据的收集，rrdtool关系着数据存储和图表的生成，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），它可以存储的数据笔数在建立时就已经定义mysql

安装rrdtoolnginx

getconf LONG_BIT
rpm -ivh http://apt.sw.be/redhat/el6/en/i386/rpmforge/RPMS/rpmforge-release-0.5.2-2.el6.rf.i686.rpm
rpm -ivh http://apt.sw.be/redhat/el6/en/x86_64/rpmforge/RPMS/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm

yum install rrdtool -y

安装配置snmpc++

yum install net-snmp net-snmp-libs net-snmp-utils -y
chkconfig snmpd on

加入防火墙数据库

/sbin/iptables -I INPUT -p udp -m udp -s 101.199.100.150  --dport 161 -jACCEPT
/sbin/iptables -I INPUT -p udp -m udp -s 220.181.150.98  --dport 161 -jACCEPT
/sbin/iptables -I INPUT -p udp -m udp -s 180.153.229.230  --dport 161 -jACCEPT

/sbin/iptables -I INPUT -p udp -m udp -s 103.28.10.245   --dport 161 -jACCEPT

删除vim

iptables -D  INPUT  1

查看防火墙api

iptables -L -n  --line-number

结果网络

安装cacti

cd /usr/loca/src
wget http://www.cacti.net/downloads/cacti-0.8.8b.tar.gz
tar xzf cacti-0.8.8b.tar.gz
mv cacti-0.8.8b /data/www/cacti
cd !$
mysql -urott -p  -e 'create database cacti'
mysql -uroot -p cacti < cacti.sql

受权

GRANT ALL ON cacti.* TO cactiuser@localhost IDENTIFIED BY 'cactipassword';

修改配置文件 include/config.php

加入cron

echo "*/5 * * * * cactiuser php /data/www/cacti/poller.php > /dev/null 2>&1">>/etc/crontab

访问后台

出现以上则说明成功

过5分钟过，不出意外的话则能够看到监控的图片了
