当开启bin-log日志时，会生成很多mysql-bin.0000*类似的文件，而且可能会占用很大的硬盘空间。对于自己的测试机器或硬盘比较紧张的vps，而又不需要做master，slave的配置，完全可以关闭日志功能。
关闭操作很简单，找到配置文件my.cnf，对于linux，一般默认在/etc目录下，打开此文件，使用井号(#)注释掉如下两个配置项目即可。
log-bin=mysql-bin binlog_format=mixed
配置修改好后需要重启mysqld服务才能生效。可能在重启时候会收到一个错误，“ERROR 1186 (HY000): Binlog closed, cannot RESET MASTER”，解决办法是先登入到mysql命令行中执行 reset master 即可。reset master的用途就是删除先前所以的bin-log日志文件。所以在master、slave配置环境中慎用此命令。
