"MySQL" MySQL audit operation Record

Server_audit is a built-in MARIADB audit plugin that works equally well in MySQL and is used primarily to record user actions

1. Installation:

通过show variables like ‘plugin_dir‘;查看你的插件目录，我的是：/usr/lib64/mysql/plugin/????把下载好的插件server_audit.so复制到/usr/lib64/mysql/plugin/ 注意chmod+x?server_audit.so登录mysql执行插件安装命令：INSTALL PLUGIN server_audit SONAME ‘server_audit.so‘;插件安装成功后有这些全局变量：show variables like ‘%audit%‘;

2. Configuration:

进入mysql 执行：更改全局变量set global server_audit_excl_users=‘root‘;set global server_audit_events=‘QUERY_DDL,QUERY_DML‘;set global server_audit_file_path =‘/mysqllog/‘;set global server_audit_file_rotate_size=1073741824;set global server_audit_file_rotations=10;set global server_audit_file_rotate_now=ON;set global server_audit_logging=on;在my.cnf 增加#auditserver_audit_events=‘QUERY_DDL,QUERY_DML‘server_audit_logging=onserver_audit_file_path =/mysqllog/server_audit_file_rotate_size=1Gserver_audit_file_rotations=10server_audit_file_rotate_now=ONserver_audit_excl_users=root

3. Recommend closing general log

set global general_log=off;在my.cnf注释general_log_file = /mysqllog/mysql.loggeneral_log = 1

4. Parameter Description:

详细请参考：https://mariadb.com/kb/en/mariadb/server_audit-system-variables/server_audit_output_type：指定日志输出类型，可为SYSLOG或FILEserver_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)，如果开启了查询缓存(query cache)，查询直接从查询缓存返回数据，将没有table记录server_audit_file_path：如server_audit_output_type为FILE，使用该变量设置存储日志的文件，可以指定目录，默认存放在数据目录的server_audit.log文件中server_audit_file_rotate_size：限制日志文件的大小server_audit_file_rotations：指定日志文件的数量，如果为0日志将从不轮转server_audit_file_rotate_now：强制日志文件轮转server_audit_incl_users：指定哪些用户的活动将记录，connect将不受此变量影响，该变量比server_audit_excl_users优先级高server_audit_syslog_facility：默认为LOG_USER，指定facilityserver_audit_syslog_ident：设置ident，作为每个syslog记录的一部分server_audit_syslog_info：指定的info字符串将添加到syslog记录server_audit_syslog_priority：定义记录日志的syslogd priorityserver_audit_excl_users：该列表的用户行为将不记录，connect将不受该设置影响server_audit_mode：标识版本，用于开发测试

5. Uninstall

mysql> UNINSTALL PLUGIN server_audit;mysql> show variables like ‘%audit%‘;Empty set (0.00 sec)
