MySQL的binlog日志位置可通过show variables like '�tadir%';查看，直接打开无法查看，要看其内容2个办法：
1、登录到mysql查看binlog 只查看第一个binlog文件的内容 mysql> show binlog events;
查看指定binlog文件的内容 mysql> show binlog events in 'mysql-bin.000002';
mysql> show binlog events in 'mysql-bin.000001'; ------------------ ------ ------------- ----------- ------------- ----------------------------------------------------------- | Log_name | Pos | Event_type | Server_id | End_log_pos | Info | ------------------ ------ ------------- ----------- ------------- ----------------------------------------------------------- | mysql-bin.000001 | 4 | Format_desc | 195 | 106 | Server ver: 5.1.73-log, Binlog ver: 4 | | mysql-bin.000001 | 106 | Query | 195 | 198 | use `Hadoop`; delete from user where id=3 | | mysql-bin.000001 | 198 | Intvar | 195 | 226 | INSERT_ID=4 | | mysql-bin.000001 | 226 | Query | 195 | 332 | use `hadoop`; INSERT INTO user (id,name)VALUES (NULL,1) | | mysql-bin.000001 | 332 | Query | 195 | 424 | use `hadoop`; delete from user where id=3 | | mysql-bin.000001 | 424 | Intvar | 195 | 452 | INSERT_ID=5 | | mysql-bin.000001 | 452 | Query | 195 | 560 | use `hadoop`; INSERT INTO user (id,name)VALUES (NULL,222) | | mysql-bin.000001 | 560 | Query | 195 | 660 | use `hadoop`; DELETE FROM `user` WHERE (`id`='1') | | mysql-bin.000001 | 660 | Intvar | 195 | 688 | INSERT_ID=6 | | mysql-bin.000001 | 688 | Query | 195 | 795 | use `hadoop`; INSERT INTO `user` (`name`) VALUES ('555') | | mysql-bin.000001 | 795 | Intvar | 195 | 823 | INSERT_ID=7 | | mysql-bin.000001 | 823 | Query | 195 | 930 | use `hadoop`; INSERT INTO `user` (`name`) VALUES ('555') | | mysql-bin.000001 | 930 | Intvar | 195 | 958 | INSERT_ID=8 | | mysql-bin.000001 | 958 | Query | 195 | 1065 | use `hadoop`; INSERT INTO `user` (`name`) VALUES ('555') | | mysql-bin.000001 | 1065 | Intvar | 195 | 1093 | INSERT_ID=9 | | mysql-bin.000001 | 1093 | Query | 195 | 1200 | use `hadoop`; INSERT INTO `user` (`name`) VALUES ('555') | | mysql-bin.000001 | 1200 | Query | 195 | 1300 | use `hadoop`; DELETE FROM `user` WHERE (`id`='9') | | mysql-bin.000001 | 1300 | Query | 195 | 1400 | use `hadoop`; DELETE FROM `user` WHERE (`id`='8') | | mysql-bin.000001 | 1400 | Query | 195 | 1500 | use `hadoop`; DELETE FROM `user` WHERE (`id`='7') | | mysql-bin.000001 | 1500 | Query | 195 | 1600 | use `hadoop`; DELETE FROM `user` WHERE (`id`='4') | | mysql-bin.000001 | 1600 | Query | 195 | 1700 | use `hadoop`; DELETE FROM `user` WHERE (`id`='5') | | mysql-bin.000001 | 1700 | Query | 195 | 1800 | use `hadoop`; DELETE FROM `user` WHERE (`id`='6') | | mysql-bin.000001 | 1800 | Intvar | 195 | 1828 | INSERT_ID=10 | | mysql-bin.000001 | 1828 | Query | 195 | 1935 | use `hadoop`; INSERT INTO `user` (`name`) VALUES ('555') | | mysql-bin.000001 | 1935 | Intvar | 195 | 1963 | INSERT_ID=11 | | mysql-bin.000001 | 1963 | Query | 195 | 2070 | use `hadoop`; INSERT INTO `user` (`name`) VALUES ('666') | | mysql-bin.000001 | 2070 | Intvar | 195 | 2098 | INSERT_ID=12 | | mysql-bin.000001 | 2098 | Query | 195 | 2205 | use `hadoop`; INSERT INTO `user` (`name`) VALUES ('777') | ------------------ ------ ------------- ----------- ------------- -----------------------------------------------------------
查看当前正在写入的binlog文件 mysql> show master statusG
mysql> show master statusG *************************** 1. row *************************** File: mysql-bin.000002 Position: 106 Binlog_Do_DB: Binlog_Ignore_DB: mysql,information_schema,performance_schema 1 row in set (0.00 sec)
获取binlog文件列表 mysql> show binary logs;
mysql> show binary logs; ------------------ ----------- | Log_name | File_size | ------------------ ----------- | mysql-bin.000001 | 3548 | | mysql-bin.000002 | 106 | ------------------ ----------- 2 rows in set (0.00 sec)
2、用mysqlbinlog工具查看 基于开始/结束时间 [root@hd3 ~]# mysqlbinlog --start-datetime='2016-08-02 00:00:00' --stop-datetime='2016-08-03 23:01:01' -d hadoop /var/lib/mysql/mysql-bin.000001
基于pos值，注：hadoop是库名，/var/lib/mysql/mysql-bin.000001是二进制文件路径 [root@hd3 ~]# mysqlbinlog --start-position=2098 --stop-position=2205 -d hadoop /var/lib/mysql/mysql-bin.000001
