在MySQL数据库中,mysql-bin.000001、mysql- bin.000002等文件是数据库的操作日志,例如UPDATE一个表,或者DELETE一些数据,即使该语句没有匹配的数据,这个命令也会存储到日志文件中,还包括每个语句执行的时间,也会记录进去的。 但是这些文件的生长速度是

在MySQL数据库中,mysql-bin.000001、mysql- bin.000002等文件是数据库的操作日志,例如UPDATE一个表,或者DELETE一些数据,即使该语句没有匹配的数据,这个命令也会存储到日志文件中,还包括每个语句执行的时间,也会记录进去的。


但是这些文件的生长速度是很快的,特别占用服务器资源。当服务器资源不够充足的情况下,我们可以选择定期删除这些日志文件,或者修改配置文件,不让日志生成。

1、删除这些日志

直接删除mysql-bin.000开头的文件,包括mysql-bin.index这个文件。


2、修改配置文件,使之不再生成这些日志

编辑my.cnf 文件,命令:vi /etc/my.cnf

注释掉 log-bin=mysql-bin 这个属性

这样以来,那些很占用磁盘资源的日志文件就不会再有了,不过这样也就不能再查询历史操作记录了。
