29 rows in set (0.00 sec)
audit记录的命令,默认为记录所有命令
可以设置为任意dml、dcl、ddl的组合
如：audit_record_cmds=select,insert,delete,update
audit_record_objs
audit记录操作的对象,默认为记录所有对象,
可以用SET GLOBAL audit_record_objs=NULL设置为默认
也可以指定为下面的格式
audit_record_objs=,test.*,mysql.*,information_schema.*
测试如下:
查看是否开启audit功能:
mysql> show variables like 'audit_json_file';
+-----------------+-------+
| Variable_name | Value |
+-----------------+-------+
| audit_json_file | OFF |
+-----------------+-------+
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)
mysql> show variables like 'audit_json_file';
+-----------------+-------+
| Variable_name | Value |
+-----------------+-------+
| audit_json_file | ON |
+-----------------+-------+
1 row in set (0.00 sec)
审计test库的所有对象:
mysql> SET GLOBAL audit_record_objs='test.*';
Query OK, 0 rows affected (0.00 sec)
审计test库的insert,update和delete操作：
mysql> set global audit_record_cmds='insert,delete,update';
Query OK, 0 rows affected (0.00 sec)
查看记录文件的路径和名称信息:
mysql> show variables like 'audit_json_log_file';
+---------------------+------------------+
| Variable_name | Value |
+---------------------+------------------+
| audit_json_log_file | mysql-audit.json |
+---------------------+------------------+
1 row in set (0.00 sec)
文件路径如下:
mysql> system find / -name mysql-audit.json
/usr/local/mysql/data/mysql-audit.json
对test库下的person表做insert,update和delete测试:
mysql> insert into person values('5','liuyb','29');
Query OK, 1 row affected (0.03 sec)
mysql> update person set age='55' where name='dsf';
Query OK, 2 rows affected (0.04 sec)
Rows matched: 2 Changed: 2 Warnings: 0
mysql> delete from person where name='cf';
Query OK, 1 row affected (0.03 sec)
mysql> select * from person;
+----+----------+------+
| id | name | age |
+----+----------+------+
| 2 | dsf | 55 |
| 3 | dsf | 55 |
| 4 | chenfeng | 38 |
| 5 | liuyb | 29 |
+----+----------+------+
4 rows in set (0.00 sec)
打开/usr/local/mysql/data/mysql-audit.json文件查看审计数据:
[root@localhost lib]# cat /usr/local/mysql/data/mysql-audit.json
{"msg-type":"header","date":"1494389691599","audit-version":"1.1.2-694","audit-protocol-version":"1.0","hostname":"localhost","mysql-version":"5.6.27-log","mysql-program":"/usr/local/mysql/bin/mysqld","mysql-socket":"/tmp/mysql.sock","mysql-port":"3306","server_pid":"41506"}

可以看到审计结果里有对test库person表的操作记录(insert,update和delete),至此，audit插件安装成功.
ps:比较重要的地方。。。。
Offset Extraction指定，目前macfee audit plugin还没有提供统一的API的，所以要手动提取offset
1) 下载官方脚本 ：https://raw.github.com/mcafee/mysql-audit/master/offset-extract/offset-extract.sh
2) chmod u+x offset-extract.sh
3) ./offset-extract.sh /usr/local/mysql/bin/mysqld
[root@10_5_12_15 audit-plugin-mysql-5.5]# ./offset-extract.sh /usr/local/mysql/bin/mysqld
//offsets for: /usr/local/mysql/bin/mysqld (5.5.21-rel25.1-log)
{"5.5.21-rel25.1","a877e71dd4ddc965390714ae8be2e540",
6456, 6504, 4064, 4504, 104, 2576
},
上面的6456, 6504, 4064, 4504, 104, 2576数字要添加到/etc/my.cnf的 [mysqld]下
4、配置和验证
1）在/etc/my.cnf中的[mysqld]下添加下面两行
#Audit Plugin#
plugin-load=AUDIT=libaudit_plugin.so
audit_offsets=6456, 6504, 4064, 4504, 104, 2576
