MySQL查看binlog日志内容

时间:2019-01-04  来源:未知  作者:admin666

MySQL的binlog日志位置可通过show variables like '%datadir%';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';
+------------------+------+-------------+-----------+-------------+-----------------------------------------------------------+

查看当前正在写入的binlog文件
mysql> show master status\G

mysql> show master status\G
*************************** 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
