MYSQL 的审计日志插件，可惜目前只是LINUX用：
来自McAfee的MySQL插件，为MySQL提供审计功能，重点是安全性和审计要求。该插件可以用作独立的审核解决方案，也可以配置为将数据提供给外部监视工具。
插件下载地址：
https://bintray.com/mcafee/mysql-audit-plugin/release/1.1.4-725#files
首先查看mysql的插件保存目录：
mysql> show global variables like 'plugin_dir';
+---------------+---------------------------------------------+
| Variable_name | Value |
+---------------+---------------------------------------------+
| plugin_dir | /usr/local/mysql-5.7.17/lib64/mysql/plugin/ |
+---------------+---------------------------------------------+
1 row in set (0.00 sec)
把上面下载的插件复制到上面的目录下：
unzip audit-plugin-mysql-5.7-1.1.4-725-linux-x86_64.zip
cd audit-plugin-mysql-5.7-1.1.4-725
cp lib/libaudit_plugin.so /usr/local/mysql-5.7.17/lib64/mysql/plugin/
进入mysql命令窗口，安装插件：
mysql> INSTALL PLUGIN AUDIT SONAME 'libaudit_plugin.so';
Query OK, 0 rows affected (0.06 sec)
查看mysql当前已经加载了哪些插件：
mysql> show plugins;

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。
