上一篇给大家分享了监控Nginx《项目实战：创建模板，监控Nginx状态、服务信息》，这里跟大家分享一下监控MySQL的记录，如果你没有安装MySQL可以参考我另一篇博文《ubuntu安装配置LNMP》，Let's go!
Zabbix监控MySQL数据库
一、客户端
Ubuntu普通用户登录
1、 登陆MySQL
$ mysql -uroot -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 20000023
Server version: 5.5.46-0ubuntu0.14.04.2 (Ubuntu)
Copyright (c) 2000, 2015, Oracle and/or its affiliates. All rights reserved.
Oracle is a registered trademark of Oracle Corporation and/or its
affiliates. Other names may be trademarks of their respective
owners.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql>
2、 创建zabbix用户用于发送数据
mysql> GRANT USAGE ON*.*TO'zabbix'@'localhost'IDENTIFIED BY'You_passwd';
Query OK, 0 rows affected (0.00 sec)
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)
mysql> \q
Bye
3、 测试zabbix用户登陆
$ mysql -uzabbix -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 20000582
Server version: 5.5.46-0ubuntu0.14.04.2 (Ubuntu)
Copyright (c) 2000, 2015, Oracle and/or its affiliates. All rights reserved.

affiliates. Other names may be trademarks of their respective
owners.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql> \q
Bye
4、 查找MySQL进程所在的位置
$ sudo find / -name *sock -print
[sudo] password for bdyun:
/run/mysqld/mysqld.sock #MySQL进程所在的位置
/sys/kernel/debug/tracing/events/sock
/lib/modules/3.13.0-32-generic/kernel/net/vmw_vsock
/usr/src/linux-headers-3.13.0-32/net/vmw_vsock
5、 新建配置文件
$ sudo vi /etc/zabbix/.my.cnf
$ cat /etc/zabbix/.my.cnf
[mysql]
host=localhost
user=zabbix #用来发送数据的用户
password=Bd_zabbix #用来发送数据的用户密码
socket=/run/mysqld/mysqld.sock
[mysqladmin]
host=localhost
user=zabbix #用来发送数据的用户
password=Bd_zabbix #用来发送数据的用户密码
socket=/run/mysqld/mysqld.sock #MySQL进程所在的位置
6、 修改文件userparameter_mysql.conf
查找文件所在位置
$ sudo find / -name userparameter_mysql.conf
/usr/share/doc/zabbix-agent/examples/userparameter_mysql.conf
复制文件到/etc/zabbix/zabbix_agentd.conf.d/userparameter_mysql.conf
$ sudo cp /usr/share/doc/zabbix-agent/examples/userparameter_mysql.conf /etc/zabbix/zabbix_agentd.conf.d/userparameter_mysql.conf
$ ls /etc/zabbix/zabbix_agentd.conf.d/
nginx.conf userparameter_mysql.conf
这个文件用于制定Zabbix Agent如何获取MySQL数据，我们需要将所有的/var/lib/zabbix修改为当前.my.cnf文件的路径/etc/zabbix。设置完 成之后保存并重启Zabbix Agent
$ sudo sed -i 's@/var/lib/zabbix@/etc/zabbix@g' /etc/zabbix/zabbix_agentd.conf.d/userparameter_mysql.conf
$ sudo service zabbix-agent restart
zabbix-agent stop/waiting
zabbix-agent start/running, process 32121
7、 重启服务
$ sudo service zabbix-agent restart
zabbix-agent stop/waiting
zabbix-agent start/running, process 32121
二、服务端
1、为监控主机选择、添加MySQL模板
ConfigurationèHostsèTemplates
2、查看图组数据图形
