使用zabbix监控mysql

Posted 2021-02-05 taj-zhang

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

[[email protected] ~]# 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
[[email protected] ~]# 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

[[email protected] ~]# 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
[[email protected] dev]# cd /var/lib/zabbix/percona/script

[[email protected] scripts]# chmod +x ss_get_mysql_stats.php.cnf
[[email protected] 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

[[email protected] ~]# /etc/init.d/zabbix-agent restart
Shutting down Zabbix agent:                                [  OK  ]
Starting Zabbix agent:                                     [  OK  ]
#重启服务
[[email protected] ~]# cd /var/lib/zabbix/percona/scripts/
[[email protected] 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)[[email protected] 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
[[email protected] scripts]# mkdir /var/lib/mysql/
[[email protected] scripts]# ln -s /tmp/mysql.sock /var/lib/mysql/mysql.sock
[[email protected] scripts]# /usr/bin/php -q ./ss_get_mysql_stats.php --host ‘localhost‘ --items gg

#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
