Mysql5.6审计功能
1. 前言
2. 开启审计
2.1 配置文件载入
[mysqld] plugin-load=audit_log.so
假设希望数据库强制开启审计功能,假设不开启的话server不启动,或者审计功能不能进行时server挂住。增加
[mysqld] plugin-load=audit_log.so audit-log=FORCE_PLUS_PERMANENT
2.2 载入插件列表
mysql> INSTALL PLUGIN audit_log SONAME 'audit_log.so';
3. 參数介绍
3.1 audit_log_buffer_size
3.2 audit_log_connection_policy
Value | Description |
---|---|
ALL |
Log all connection events |
ERRORS |
Log only failed connection events |
NONE |
Do not log connection events |
3.3 audit_log_current_session
audit_log_current_session:标志当前会话是否进入审计。是个仅仅读參数。仅仅能通过 audit_log_exclude_accounts和 audit_log_include_accounts来控制哪儿些进入会话审计。3.4 audit_log_exclude_accounts/audit_log_include_accounts
3.5 audit_log_file
3.6 audit_log_flush
3.7 audit_log_format
3:更改audit_log_format參数,并重新启动mysql,重新启动后会自己主动生成一个新的audit.log文件
Value | Description |
---|---|
ALL |
Log all events |
LOGINS |
Log only login events |
QUERIES |
Log only query events |
NONE |
Log nothing (disable the audit stream |
3.8 audit_log_statement_policy
audit_log_statement_policy:记录了语句的审计策略,可能会被audit_log_policy给覆盖:Value | Description |
---|---|
ALL |
Log all statement events |
ERRORS |
Log only failed statement events |
NONE |
Do not log statement events |
3.9 audit_log_rotate_on_size
当參数大于0的时候,当审计日志超过限制后。会自己主动的重命名为加时间戳后缀的日志文件。
同一时候创建新的审计日志。
3.10 audit_log_strategy
Value | Meaning |
---|---|
ASYNCHRONOUS |
Log asynchronously, wait for space in output buffer |
PERFORMANCE |
Log asynchronously, drop request if insufficient space in output buffer |
SEMISYNCHRONOUS |
Log synchronously, permit caching by operating system |
SYNCHRONOUS |
Log synchronously, call sync() after each
request |
