MySQL社区版没有自带的设计功能或插件。调研发现MariaDB的audit plugin 同样适用于MySQL，支持更细粒度的审计，比如只审计DDL操作，满足我们的需求。因为最近测试环境的某表结构经常性的被变更且数据被清空的情况，所以引入MariaDB的插件对DDL进行审计
查看MySQL的插件路径
mysql> show global variables like ‘%plugin%‘; +---------------+------------------------------+ | Variable_name | Value | +---------------+------------------------------+ | plugin_dir | /usr/local/mysql/lib/plugin/ | +---------------+------------------------------+ 1 row in set (0.00 sec) mysql> select version(); +------------+ | version() | +------------+ | 5.6.33-log | +------------+ 1 row in set (0.00 sec)
我选择下载的插件版本文件为 server_audit-1.4.0.tar.gz
解压后将插件文件server_audit.so拷贝到MySQL的插件文件目录下
安装
mysql> INSTALL PLUGIN server_audit SONAME ‘server_audit.so‘; Query OK, 0 rows affected (0.02 sec)
#在线安装加载插件重启后会失效，可以在配置文件中配置
[mysqld]
...
plugin_load=server_audit=server_audit.so
配置审计项
# 安装完之后相关的配置项有 SHOW GLOBAL VARIABLES LIKE ‘server_audit%‘; +-------------------------------+-----------------------+ | Variable_name | Value | +-------------------------------+-----------------------+ | server_audit_events | CONNECT,QUERY,TABLE | | 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_logging | ON | | server_audit_mode | 0 | | 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 | +-------------------------------+-----------------------+
根据我们的需求设置
mysql> set global server_audit_events=‘query_ddl,table‘; Query OK, 0 rows affected (0.00 sec) mysql> set global server_audit_logging=on; Query OK, 0 rows affected (0.00 sec)
设置完之后关于ddl的审计日志如
20180416 11:25:22,mysql-5.6.dev.yz,root,localhost,34950852,21554,QUERY,test,‘truncate table t1‘,0
关于server_audit_events可选的参数有connect：会记录所有的连接，包括失败的以及关闭连接的日志，如日志中记录的，但是对我们来说不关心这些
[root@mysql-5.6.dev.yz 3306_develop]# tailf server_audit.log 20180416 11:22:42,mysql-5.6.dev.yz,root,10.211.253.104,34950731,0,CONNECT,test,,0 20180416 11:22:48,mysql-5.6.dev.yz,admin,10.211.253.153,34950655,0,DISCONNECT,test,,0 20180416 11:22:48,mysql-5.6.dev.yz,admin,10.211.253.153,34950732,0,CONNECT,test,,0 20180416 11:22:49,mysql-5.6.dev.yz,admin,10.211.253.101,34950664,0,DISCONNECT,test,,0
