删除MySQL二进制日志(log-bin)

本文章来告诉大怎么在mysql命令模式下载删除 MySQL 二进制日志(log-bin)的方法，有需要的朋友可参考。

查找当前有哪些二进制日志文件

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)
