mysql 5.7 安装SQL审计

1、为了数据库安全准备开启SQL审计功能，选用MariaDB Audit Plugin的插件(Oracle MySQL 5.7.24)

mysql> show variables like 'version';
+---------------+------------+
| Variable_name | Value      |
+---------------+------------+
| version       | 5.7.24-log |
+---------------+------------+
1 row in set (0.00 sec)

mysql> show variables like 'plugin_dir';
+---------------+--------------------------+
| Variable_name | Value                    |
+---------------+--------------------------+
| plugin_dir    | /usr/lib64/mysql/plugin/ |
+---------------+--------------------------+
1 row in set (0.01 sec)

2、下载插件并解压

wget https://downloads.mariadb.com/MariaDB/mariadb-5.5.66/bintar-linux-x86_64/mariadb-5.5.66-linux-x86_64.tar.gz

tar -zxvf mariadb-5.5.66-linux-x86_64.tar.gz 

cp mariadb-5.5.66-linux-x86_64/lib/plugin/server_audit.so /usr/lib64/mysql/plugin/

chmod 755 /usr/lib64/mysql/plugin/server_audit.so

3、安装插件并启用

mysql> install plugin server_audit SONAME 'server_audit.so';
Query OK, 0 rows affected (0.00 sec)

mysql> show variables like '%audit%';
+-------------------------------+-----------------------+
| Variable_name                 | Value                 |
+-------------------------------+-----------------------+
| server_audit_events           |                       |
| server_audit_excl_users       |                       |
| server_audit_file_path        | server_audit.log      |
| server_audit_file_rotate_now  | OFF                   |
| server_audit_file_rotate_size | 1000000               |
| server_audit_file_rotations   | 9                     |
| server_audit_incl_users       |                       |
| server_audit_loc_info         |                       |
| server_audit_logging          | OFF                   |
| server_audit_mode             | 1                     |
| server_audit_output_type      | file                  |
| server_audit_query_log_limit  | 1024                  |
| server_audit_syslog_facility  | LOG_USER              |
| server_audit_syslog_ident     | mysql-server_auditing |
| server_audit_syslog_info      |                       |
| server_audit_syslog_priority  | LOG_INFO              |
+-------------------------------+-----------------------+
16 rows in set (0.00 sec)

mysql> set global server_audit_logging=1;
Query OK, 0 rows affected (0.00 sec)

4、配置文件添加启动

vi /etc/my.cnf

[mysqld]
server_audit_logging=on

5、查看日志

mysql> show variables like 'datadir';
+---------------+------------+
| Variable_name | Value      |
+---------------+------------+
| datadir       | /u01/data/ |
+---------------+------------+
1 row in set (0.00 sec)

tail -f /u01/data/server_audit.log 
20191203 17:15:03,mysql_node01,test_user,192.168.1.2,14016,573201,QUERY,test,'SHOW GLOBAL STATUS',0

6、配置说明
server_audit_logging：启动或关闭审计
server_audit_events：指定记录事件的类型，可以用逗号分隔的多个值(connect,query,table) ，默认为空代表审计所有事件。
server_audit_incl_users：指定哪些用户的活动将记录，默认审计所有用户，该变量比server_audit_excl_users优先级高
server_audit_excl_users：指定哪些用户行为不记录
server_audit_output_type：指定日志输出类型，可为SYSLOG或FILE，缺省输出至审计文件
