查看安装后的插件版本：
mysql> show global status like 'AUDIT_version';
+---------------+-----------+
| Variable_name | Value |
+---------------+-----------+
| Audit_version | 1.1.4-725 |
+---------------+-----------+
1 row in set (0.00 sec)
开启audit功能：
mysql> SET GLOBAL audit_json_file=ON;
Query OK, 0 rows affected (0.00 sec)
可以查看插件有哪些可配置的参数：
mysql> SHOW GLOBAL VARIABLES LIKE '%audi%';
详细的参数说明，可以直接访问官方说明：
https://github.com/mcafee/mysql-audit/wiki/Configuration
最后为了保证重启数据库，配置不丢失，修改my.cnf 配置文件，将下面的配置添加到[mysqld]中，所以在配置文件中my.cnf加入参数：
audit_json_file=on #保证mysql重启后自动启动插件
plugin-load=AUDIT=libaudit_plugin.so #防止删除了插件，重启后又会加载
audit_record_cmds=’insert,delete,update,create,drop,alter,grant,truncate’ #要记录哪些命令语句,因为默认记录所有操作；
保存重启即可看到效果。
