使用zabbix监控mysql

系统版本: centos6 x86_64

mysql版本: mysql5.6

实施目的: 监控mysql

客户端配置:

1、准备工作:搭建zabbix服务，使服务端客户端连接成功，并有基础监控项

2、使用percona监控服务，因为percona是监控项更全面，原本支持cacti 目前支持zabbix

yum install http://www.percona.com/downloads/percona-release/redhat/0.1-3/percona-release-0.1-3.noarch.rpm -y

#安装percona源（agent安装）

yum install percona-zabbix-templates php php-mysql

#安装监控脚本，因为要调用php发送给服务器端所以需安装php组件(agent安装)

3、复制配置文件到agent配置目录

[root@fmysql1 ~]# rpm -ql percona-zabbix-templates

/var/lib/zabbix/percona

/var/lib/zabbix/percona/scripts

/var/lib/zabbix/percona/scripts/get_mysql_stats_wrapper.sh

/var/lib/zabbix/percona/scripts/ss_get_mysql_stats.php

/var/lib/zabbix/percona/templates

/var/lib/zabbix/percona/templates/userparameter_percona_mysql.conf

/var/lib/zabbix/percona/templates/zabbix_agent_template_percona_mysql_server_ht_2.0.9-sver1.1.8.xml

[root@fmysql1 ~]# cp /var/lib/zabbix/percona/templates/userparameter_percona_mysql.conf /etc/zabbix/zabbix_agentd.d/

4、进入mysql配置zabbix专用监控账户

mysql> GRANT SELECT, PROCESS, SUPER, REPLICATION CLIENT ON *.* TO 'zabbix'@'localhost' IDENTIFIED BY "wxgdwxwx2323";

5、配置mysql登录

[root@bmysql1 ~]# cat /var/lib/zabbix/percona/scripts/ss_get_mysql_stats.php.cnf

<?php

$mysql_user = 'zabbix';

$mysql_pass = 'wxgdwxwx2323';
$mysql_port = 3306;
#后期发现监控无法取值原因.cnf文件没有加入执行权限
[root@bmysql2 dev]# cd /var/lib/zabbix/percona/script

[root@bmysql2 scripts]# chmod +x ss_get_mysql_stats.php.cnf
[root@bmysql2 scripts]# ll
total 68
-rwxr-xr-x 1 root root 1251 Jan 10 2018 get_mysql_stats_wrapper.sh
-rwxr-xr-x 1 root root 60681 Jan 25 11:32 ss_get_mysql_stats.php
-rwxr-xr-x 1 root root 60 Jan 25 14:22 ss_get_mysql_stats.php.cnf

6、测试

[root@fmysql1 ~]# /etc/init.d/zabbix-agent restart

Shutting down Zabbix agent:                                [  OK  ]

Starting Zabbix agent:                                     [  OK  ]

#重启服务

[root@fmysql1 ~]# cd /var/lib/zabbix/percona/scripts/

[root@fmysql1 scripts]# /usr/bin/php -q ./ss_get_mysql_stats.php --host 'localhost' --items gg

ERROR: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)[root@fmysql1 scripts]#

#提示获取不到无法连接sock接口文件,可能是因为自己编译安装sock文件在其它目录,直接找到现有sock软链接到这个报错目录下就好了

[root@fmysql1 scripts]# mkdir /var/lib/mysql/

[root@fmysql1 scripts]# ln -s /tmp/mysql.sock /var/lib/mysql/mysql.sock

[root@fmysql1 scripts]# /usr/bin/php -q ./ss_get_mysql_stats.php --host 'localhost' --items gg

gg:[root@fmysql1 scripts]#

#取值成功！客户端配置OVER
zabbix_get -s 172.18.10.120 -p 10050 -k "MySQL.Handler-commit"
#服务端测试
