1、查看mysql插件存放目录
mysql> SHOW GLOBAL VARIABLES LIKE 'plugin_dir';
+---------------+-----------------------------------+
| Variable_name | Value |
+---------------+-----------------------------------+
| plugin_dir | /usr/local/mysql/lib/plugin/ |
+---------------+-----------------------------------+
1 row in set (0.01 sec)
2、复制libaudit_plugin.so 至 mysql插件目录
mv libaudit_plugin.so /usr/local/mysql/lib/plugin/
chmod a+x /usr/local/mysql/lib/plugin/*
chown mysql:mysql /usr/local/mysql/lib/plugin/*
3、安装插件
初使使用在线安装，但是安装失败
mysql> INSTALL PLUGIN AUDIT SONAME 'libaudit_plugin.so';
ERROR 1524 (HY000): Plugin 'AUDIT' is not loaded
然后使用修改配置，然后重启数据库，官方推荐使用修改配置方式安装。
Note: On production systems, McAfee recommends using the plugin-load option for installing the audit plugin.
修改my.cnf文件，添加加载审计插件代码
plugin-load=AUDIT=libaudit_plugin.so
audit_json_file=on
audit_force_record_logins=on
audit_json_file_sync=1
重启数据库
/etc/init.d/mysql.server restart
4、查看插件状态
mysql> show plugins;

5、查看插件的配置参数
mysql> show global VARIABLES like '%audit%';
+---------------------------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+

6、验证审计
[root@VM_166_132 mysqldata]# tailf /data/mysql/mysql-audit.json
{"msg-type":"activity","date":"1480659848340","thread-id":"4","query-id":"12","user":"root","priv_user":"root","host":"","ip":"127.0.0.1","cmd":"show_variables","objects":[{"db":"information_schema","name":"/tmp/#sql_6a75_0","obj_type":"TABLE"}],"query":"SHOW GLOBAL VARIABLES LIKE 'plugin_dir'"}
{"msg-type":"activity","date":"1480659883722","thread-id":"4","query-id":"13","user":"root","priv_user":"root","host":"","ip":"127.0.0.1","cmd":"show_plugins","objects":[{"db":"information_schema","name":"/tmp/#sql_6a75_0","obj_type":"TABLE"}],"query":"show plugins"}
7、关闭审计
mysql> set GLOBAL audit_json_file=off ;
Query OK, 0 rows affected (0.01 sec)
8、禁用插件
mysql> UNINSTALL PLUGIN AUDIT;
ERROR 1148 (42000): Uninstall AUDIT plugin disabled
在线禁用失败，采取修改配置文件，重启方式修改。
