Zabbix

Zabbix监控环境安装

准备两台VM，server端：192.168.56.144/24（zabbix） agent端：192.168.56.135/24（mysql）

依照官方文档安装zabbix
[root@zabbix zabbix]# yum install -y zabbix-server zabbix-web-2.4.7-1.el6.noarch.rpm zabbix-server-mysql-2.4.7-1.el6.x86_64.rpm zabbix-web-mysql zabbix-agent ^C
[root@zabbix zabbix]# yum install -y mysql-server mysql^C
[root@zabbix zabbix]#

修改MySQL配置文件
[mysqld]
character-set-server = utf8
init-connect = 'SET NAMES utf8'
collation-server = utf8_general_ci

创建MySQL数据库（for zabbix）
shell> mysql -uroot -p<password>
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> grant all privileges on zabbix.* to zabbix@localhost identified by '<password>';
mysql> quit;
shell> mysql -uzabbix -p<password> zabbix < database/mysql/schema.sql
# stop here if you are creating database for Zabbix proxy
shell> mysql -uzabbix -p<password> zabbix < database/mysql/images.sql
shell> mysql -uzabbix -p<password> zabbix < database/mysql/data.sql

创建表结构
cd /usr/share/doc/zabbix-server-mysql-2.4.7/create/
[root@zabbix create]# mysql -uroot -p zabbix < schema.sql
Enter password:
[root@zabbix create]# mysql -uroot -p zabbix < images.sql
Enter password:
[root@zabbix create]# mysql -uroot -p zabbix < data.sql
Enter password:

默认安装好的zabbix.conf文件
[root@zabbix conf.d]# cat /etc/httpd/conf.d/zabbix.conf
#

启动Apache

连接数据库配置
vim /etc/zabbix/zabbix_server.conf 修改DB

启动zabbix-server /etc/init.d/zabbix-server start

最终创建成功
Configuration file
"/etc/zabbix/web/zabbix.conf.php"
created: OK

Congratulations on successful installation of Zabbix frontend.

When done, press the "Finish" button

 

默认登录用户名密码Admin/zabbix（修改Admin密码，profile---->User---->change password）

修改zabbix_agent配置文件：（/etc/zabbix/zabbix_agentd.conf）Server地址

启动zabbix-agent /etc/init.d/zabbix-agent start

host指代监控的主机
item指代监控项，如CPU使用率、磁盘使用率等
trigger指代触发器，如CPU使用率超过设定值，即出发相应的操作

 

agent端（MySQL）设置：
[root@mysql zabbix]# vim /etc/zabbix/zabbix_agentd.conf
[root@mysql zabbix]# /etc/init.d/zabbix-agent start
Starting Zabbix agent: [ OK ]

设置DNS域名解析（/etc/hosts）
192.168.56.144 zabbix-server.liyang.me zabbix-server (linux-node1.example.com)
192.168.56.135 mysql.liyang.me mysql (linux-node2.example.com)

自定义监控和图表
1、修改配置文件，添加自定义的监控项
获取已登录的用户（通过uptime获取）
vim /etc/zabbix/zabbix_agentd.conf
### Option: UserParameter
# User-defined parameter to monitor. There can be several user-defined parameters.
# Format: UserParameter=<key>,<shell command>
# See 'zabbix_agentd' directory for examples.
#
# Mandatory: no
# Default:
UserParameter=login-user,uptime |awk -F ' ' '{print $4}'
[root@mysql ~]# /etc/init.d/zabbix-agent restart
Shutting down Zabbix agent: [ OK ]
Starting Zabbix agent: [ OK ]

测试：
[root@zabbix ~]# zabbix_get --host mysql --key login-user
3

2、在WEB界面上，添加自定义的监控项
Configuration--->Hosts--->select mysql(linux-node2)--->items--->create items

3、图表
Configuration--->Hosts--->select mysql(linux-node2)--->Graphics--->create graphics
