mysql bin log配置及查看

一、mysql bin日志配置：

查案命令：show variables like '%log_bin%'

log_bin：on
log_bin_basename：bin文件路径及名前缀（/var/log/mysql/mysql-bin）
log_bin_index：bin文件index（/var/log/mysql/mysql-bin.index）
server_id：n

生成的bin日志格式如下：

mysql-bin.000000  mysql-bin.000001

二、日志查看命令：

转换格式

mysqlbinlog mysql-bin.000000 > mysql-bin.000000.txt 

日志内容：

use `dbname`/*!*/;
SET TIMESTAMP=/*!*/; //开始时间
insert into `users` (`userId`, `userName`) values ('', 'helly') //操作sql
/*!*/;
