centos6.5系统cacti监控部署文档

系统要求:本文中的Linux操作系统为CentOS 6.5,以下操作均以root执行.

环境描述:

操作系统            ip                      监控类别         软件

CentOs 6.5      监控ip      监控端     lnmp环境,cactisnmp服务,rrdtool

CentOs 6.5      *                         被监控端   snmp服务

注:lnmp环境和snmp服务安装不再赘述,按照要求主要是为监控流量,未安装其他插件

  • 监控端操作

1.首先用系统自带的yum命令安装、升级所需的程序库

yum install rrdtool rrdtool-develnet-snmp-devel net-snmp-utils net-snmp-python net-snmp-perl lm_sensors-develfile-devel rpm-devel intltool libart_lgpl elfutils  mysql-devel Mod_auth_mysql php-mysql cairodejavu-fonts-common.noarch dejavu-lgc-sans-mono-fonts.noarchdejavu-sans-mono-fonts.noarch fontpackages-filesystem.noarch libXft libXrenderlibthai pango  perl-rrdtooltcp_wrappers-devel

2.将snmp服务加入启动项,并开启snmp服务

chkconfig snmpd on

sed -i "41s#default#监控ip#g" /etc/snmp/snmpd.conf

sed -i "62s#systemview#all#g" /etc/snmp/snmpd.conf

sed -i "85s/#//g" /etc/snmp/snmpd.conf

service snmpd start

3.防火墙设置

-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT

-A INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT

-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT

-A INPUT -m state --state NEW -m udp -p udp --dport 161 -j ACCEPT

-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT

-A INPUT -m state --state NEW -m udp -p udp --dport 514 -j ACCEPT

service iptables restart(重启防火墙服务)

4.cacti软件包下载:(路径:/usr/local/src

wget  http://www.cacti.net/downloads/cacti-0.8.8c.tar.gz

解压cacti-0.8.8c.tar.gz并放到nginx默认目录

tar zxvf cacti-0.8.8c.tar.gz

mv cacti-0.8.8c cacti

cp -r cacti /usr/local/nginx/html/

chown -R www:www/usr/local/nginx/html/cacti/

chmod 777 /usr/local/nginx/html/cacti/

useradd cactiuser

chown -R cactiuser:cactiuser/usr/local/nginx/html/cacti/rra

chown -R cactiuser:cactiuser/usr/local/nginx/html/cacti/log

5.Mysql设置

mysql �Cu root �Cp输入密码

mysql> create database cacti defaultcharacter set utf8;

mysql> grant all on cacti.* tocactiuser@localhost identified by 'cactiuser';

mysql> use cacti;

mysql> source/usr/local/nginx/html/cacti/cacti.sql;

mysql> flush privileges;

mysql> quit

备注:为了不修改配置文件,因此使用cactiuser用户,cactiuser密码

6.访问地址,浏览器中输入:http://监控ip/cacti/install

默认密码为admin:admin

首次登陆修改密码

7.加入开机启动项:

crontab -e

*/5 * * * * /usr/local/php/bin/php   /usr/local/nginx/html/cacti/poller.php  &> /dev/null

service crond restart #启动crond

/usr/local/php/bin/php   /usr/local/nginx/html/cacti/poller.php   #手动刷新数据

  • 被监控端操作

安装snmp服务

yum -y install net-snmp*

设置防火墙通过snmp服务161端口

sed -i '10 i\-A INPUT -m state --state NEW-m udp -p udp --dport 161 -j ACCEPT' /etc/sysconfig/iptables

service iptables restart(重启防火墙服务)

sed -i "41s#default#监控ip#g" /etc/snmp/snmpd.conf

sed -i "62s#systemview#all#g" /etc/snmp/snmpd.conf

sed -i "85s/#//g" /etc/snmp/snmpd.conf

service snmpd restart(重启snmp服务)
