先决条件:
首先你需要安装 Zabbix Servers 及 Zabbix-agentd 端:
《Zabbix Servers 3.4 源代码编译安装》
《Centos 7 Zabbix Agent 客户端源码编译安装配置》
1.配置 userparameter_mysql.conf
Zabbix源码中包含了 userparameter_mysql.conf 配置文件,只需要将其拷贝到zabbix_agentd.conf.d目录下:
$ find / -name userparameter_mysql.conf $ cd /tmp/zabbix-3.4.2/conf/zabbix_agentd/ $ cp userparameter_mysql.conf /usr/local/zabbix/etc/zabbix_agentd.conf.d/
2.修改 zabbix_agentd.conf
因为我们将userparameter_mysql.conf文件放在了zabbix_agentd.conf.d目录,所以需要取消下面注释,这样Zabbix Agent才能够加载此文件
$ vim /usr/local/zabbix/etc/zabbix_agentd.conf ... Include=/usr/local/zabbix/etc/zabbix_agentd.conf.d/*.conf ...注意:若 systemctl Zabbix-Agent.service 单元文件中已经加载此配置文件/路径,此步骤可以忽略。
3.创建监控 MariaDB(MySQL) 用户信息
MariaDB [(none)]> GRANT SELECT ON *.* TO 'zabbix'@'localhost' IDENTIFIED BY 'Renwolecom'; MariaDB [(none)]> FLUSH PRIVILEGES; MariaDB [(none)]> exit Bye注意:MySQL用户权限可根据需求设置,可参考《Linux MariaDB(MySQL)数据库更改用户权限》。
4.创建 .my.cnf 文件,添加 MariaDB(MySQL) 用户信息
$ vim /usr/local/zabbix/etc/.my.cnf # Zabbix Agent [mysql] host=localhost user=zabbix password="Renwolecom" socket=/tmp/mysql.sock [mysqladmin] host=localhost user=zabbix password="Renwolecom" socket=/tmp/mysql.sock
5.修改 userparameter_mysql.conf
修改后的内容如下:
$ cd /usr/local/zabbix/etc/zabbix_agentd.conf.d/ $ egrep -v "(^#|^$)" userparameter_mysql.conf UserParameter=mysql.status[*],echo "show global status where Variable_name='$1';" | HOME=/usr/local/zabbix/etc/ /usr/local/mysql/bin/mysql -N | awk '{print $$2}' UserParameter=mysql.size[*],bash -c 'echo "select sum($(case "$3" in both|"") echo "data_length+index_length";; data|index) echo "$3_length";; free) echo "data_free";; esac)) from information_schema.tables$([[ "$1" = "all" || ! "$1" ]] || echo " where table_schema=\"$1\"")$([[ "$2" = "all" || ! "$2" ]] || echo "and table_name=\"$2\"");" | HOME=/usr/local/zabbix/etc mysql -N' UserParameter=mysql.ping,HOME=/usr/local/zabbix/etc/ /usr/local/mysql/bin/mysqladmin ping | grep -c alive UserParameter=mysql.version,/usr/local/mysql/bin/mysql -V UserParameter=mysql.vars[*],echo "show variables where Variable_name='$1';" | HOME=/usr/local/zabbix/etc/ /usr/local/mysql/bin/mysql -N | awk '{print $$2}'注:以上内容请注意相关绝对路径。
6.重启 Zabbix-Agent 服务
$ systemctl restart zabbix-agent
最后在 Zabbix UI界面中添加MySQL监控模板即可。
