【Cacti】Linux监控软件安装与配置（一）

一、安装epel-release扩展源

[[email protected] ~]# rpm -ivh epel-release-6-8_32.noarch.rpm

二、安装lamp环境

[[email protected] ~]# yum -y install httpd php php-mysql mysql mysql-server mysql-devel php-gd libjpeg libjpeg-devel libpng libpng-devel

三、安装cacti、net-snmp、rrdtool、php-snmp

[[email protected] ~]# yum -y install cacti net-snmp net-snmp-utils rrdtool php-snmp

四、启动服务

[[email protected] ~]# /etc/init.d/mysqld start

[[email protected] ~]# /etc/init.d/httpd start

[[email protected] ~]# /etc/init.d/snmpd start

五、配置cacti

1、初始化数据库

[[email protected] ~]# mysql_secure_installation

[[email protected] ~]# mysql -uroot -p

2、配置httpd

19         <IfModule !mod_authz_core.c>

20                 # httpd 2.2

21                 Order deny,allow

22                 Allow from all

23                 Allow from localhost

24         </IfModule>

[[email protected] ~]# /etc/init.d/httpd restart

Stopping httpd:                                            [  OK  ]

Starting httpd:                                            [  OK  ]

3、创建cacti数据库

[[email protected] ~]# mysql -uroot -p -e "create database cacti"

4、创建cacti数据库用户

[[email protected] ~]# mysql -uroot -p -e "grant all on cacti.* to ‘cacti‘@‘127.0.0.1‘ identified by ‘cacti‘;"

5、导入数据库文件

[[email protected] ~]# mysql -uroot -p cacti < /usr/share/doc/cacti-0.8.8b/cacti.sql

6、配置cacti配置文件

[[email protected] ~]# vim /usr/share/cacti/include/config.php

$database_type = "mysql";

$database_default = "cacti";

$database_hostname = "127.0.0.1";

$database_username = "cacti";

$database_password = "cacti";

$database_port = "3306";

$database_ssl = false;

7、访问cacti并安装

（1）http://192.168.1.21/cacti/install，Next---->New Install---->Next

（2）保持默认<Finish>，转到登录页面，默认登录名和密码都是admin，输入会提示修改密码

（3）执行poller.php, 生成图形， 并加入计划任务

[[email protected] ~]# /usr/bin/php /usr/share/cacti/poller.php

date.timezone报错，修改php.ini相关配置

[[email protected] ~]# vim /etc/php.ini

947 date.timezone = ‘Asia/Chongqing‘

[[email protected] ~]# /usr/bin/php /usr/share/cacti/poller.php

[[email protected] ~]# crontab -e

*/5 * * * *  /usr/bin/php /usr/share/cacti/poller.php  //每5分钟执行一次

（4）查看cacti生成图形信息

八、cacti添加客户端监控

1、安装net-snmp

[[email protected] ~]# yum -y install net-snmp

2、修改snmp-conf

[[email protected] ~]# vim /etc/snmp/snmpd.conf

162 syslocation 192.168.1.251

163 syscontact Root [email protected]

55 view    systemview    included   .1.3.6.1.2.1

56 view    systemview    included   .1.3.6.1.2.1.25.1.1

[[email protected] ~]# /etc/init.d/snmpd start

3、在服务端添加配置
