方法一，删除全部二进制日志：
在mysql上执行reset master命令，那么就清除了所有的mysql-bin.*日志，并且以后日志文件名从mysql-bin.000001开始
reset master
删除部分日志：
| 代码如下 |
复制代码 |
PURGE MASTER LOGS TO & PURGE MASTER LOGS BEFORE
PURGE MASTER LOGS TO 'mysql-bin.******'命令，是将'******'编号之前的所有日志
|
进行删除
PURGE MASTER LOGS BEFORE 'yyyy-mm-dd hh:mm:ss'命令，是将在'yyyy-mm-dd hh:mm:ss'时间之前的所有日志进行删除
方法二,或者使用PURGE
PURGE {MASTER | BINARY} LOGS TO ‘log_name’
PURGE {MASTER | BINARY} LOG
查看日志
| 代码如下 |
复制代码 |
|
mysql> show binary logs;
+------------------+-----------+
| Log_name | File_size |
+------------------+-----------+
| mysql-bin.000001 | 1357315 |
| mysql-bin.000002 | 117 |
| mysql-bin.000003 | 404002 |
| mysql-bin.000004 | 2050722 |
| mysql-bin.000005 | 139103 |
| mysql-bin.000006 | 46702 |
| mysql-bin.000007 | 117 |
| mysql-bin.000008 | 98 |
| mysql-bin.000009 | 117 |
| mysql-bin.000010 | 1254 |
| mysql-bin.000011 | 117 |
| mysql-bin.000012 | 29394942 |
| mysql-bin.000013 | 422100 |
| mysql-bin.000014 | 117 |
| mysql-bin.000015 | 117 |
| mysql-bin.000016 | 98 |
| mysql-bin.000017 | 117 |
| mysql-bin.000018 | 117 |
| mysql-bin.000019 | 285300 |
| mysql-bin.000020 | 181229 |
| mysql-bin.000021 | 98 |
+------------------+-----------+
21 rows in set (0.03 sec)
|
删除bin-log(删除mysql-bin.000018之前的所有二进制日志文件)
| 代码如下 |
复制代码 |
|
mysql> purge binary logs to 'mysql-bin.000018';
Query OK, 0 rows affected (0.08 sec)
mysql> show binary logs;
+------------------+-----------+
| Log_name | File_size |
+------------------+-----------+
| mysql-bin.000018 | 117 |
| mysql-bin.000019 | 285300 |
| mysql-bin.000020 | 181229 |
| mysql-bin.000021 | 98 |
+------------------+-----------+
4 rows in set (0.00 sec)
|
查看日志
| 代码如下 |
复制代码 |
|
mysql> show binlog events;
+------------------+-----+-------------+-----------+-------------+---------------------------------------+
| Log_name | Pos | Event_type | Server_id | End_log_pos | Info |
+------------------+-----+-------------+-----------+- www.111com.net ------------+---------------------------------------+
| mysql-bin.000018 | 4 | Format_desc | 1 | 98 | Server ver: 5.0.45-log, Binlog ver: 4 |
| mysql-bin.000018 | 98 | Stop | 1 | 117 | |
+------------------+-----+-------------+-----------+-------------+---------------------------------------+
2 rows in set (0.01 sec)
|
方法三，设置日志过期时间：
修改my.cnf
| 代码如下 |
复制代码 |
|
expire_log_day=5
|
这里设置保存5天的日志，超过5天的日志会被自动删除
方法四，如果是linux系统可以使用rm删除
删除二进制日志，启动服务
| 代码如下 |
复制代码 |
# c -rf /mybinlog/*
# netstat -tnlp 查看启动的mysql进程号
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 2523/mysql
# kill 2523 （注意，如果在备份之前mysql服务是开启的，重启是不成功的，需要把这个进程先kill掉）
# service mysqld restart |
