Mysql 连接通过init_connect来初始化,官网说明:服务器为每个连接的客户端执行的字符串。该字符串由一个或多个SQL语句组成,用分号字符分隔。 例如,默认情况下每个客户端会话都启用自动提交模式。对于较旧的服务器(在MySQL 5.5.8之前), 没有全局自动提交系统变量来指定默认情况下应禁用自动提交,但作为解决方法,init_connect可用于实现相同的效果: SET GLOBAL init_connect ='SET autocommit = 0';
1.创建数据库及表
创建数据库:
create database dba;
创建表:
create table accesslog(`thread_id` int primary key auto_increment, `time` timestamp, `localname` varchar(40), `machine_name` varchar(40));
thread_id : 记录mysql 线程ID
time:记录操作时间
localname:记录操作远程IP
machine_name:记录用户
2.变量配置
查看init_connect
+---------------+-------+ | Variable_name | Value | | +---------------+-------+ | init_connect | | | init_file | | | init_slave | | +---------------+-------+ 3 rows in set (0.00 sec)
配置变量
set global init_connect='insert into dba.accesslog(thread_id,time,localname,machine_name) values(connection_id(),now(),user(),current_user());';
再次查看init_connect
+---------------+-----------------------------------------------------------------------------------------------------------------------+ | Variable_name | Value | +---------------+-----------------------------------------------------------------------------------------------------------------------+ | init_connect | insert into dba.accesslog(thread_id,time,localname,machine_name) values(connection_id(),now(),user(),current_user()); | | init_file | | | init_slave | | +---------------+-----------------------------------------------------------------------------------------------------------------------+ 3 rows in set (0.00 sec)
3.为用户赋记录日志权限
grant select,insert,update on dba.accesslog to 'zhaohongming'@'%';
4.模拟用户操作添加删除
root@localhost:(none) 11:34:49 >use sdlcqw; root@localhost:(none) 11:34:49 >crate table haha(cc int); root@localhost:(none) 11:34:49 >drop table haha;
5.查看binlog记录
导出binlog内容:
# mysqlbinlog mysql-bin.000079 > /root/9.txt
查询log表:
root@localhost:(none) 11:39:41 >use dba; Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed root@localhost:dba 11:39:50 >select * from accesslog limit 1; +-----------+---------------------+------------------------+----------------+ | thread_id | time | localname | machine_name | +-----------+---------------------+------------------------+----------------+ | 279950 | 2018-05-24 08:51:37 | zhaohongming@localhost | zhaohongming@% | +-----------+---------------------+------------------------+----------------+ 1 row in set (0.00 sec)
6.查看binlog内容
上面的线程是279950
