mysql-bin.000001文件来源以及处理方法

仔细想想没有往服务器上传什么大的文件,也不能被黑(不起眼的小网站服务器)。于是,就逐一的检查”/”下的所有文件占用磁盘空间的大小。

[root@localhost ~]# du -s /* 
6160	/bin
19380	/boot
156	/dev
21700	/etc
2383236	/home
112372	/lib
16	/lost+found
4	/media
4	/mnt
4	/opt
du: 无法访问"/proc/2187/task/2187/fd/4": 没有那个文件或目录
du: 无法访问"/proc/2187/task/2187/fdinfo/4": 没有那个文件或目录
du: 无法访问"/proc/2187/fd/4": 没有那个文件或目录
du: 无法访问"/proc/2187/fdinfo/4": 没有那个文件或目录
0	/proc
56	/root
9488	/sbin
4	/selinux
4	/srv
0	/sys
14760	/tmp
37310312	/usr
90452	/var

发现/usr占用了大约37.3G的磁盘空间,然后进入/usr检查。

[root@localhost ~]#  du -s /usr/local/*
944	/usr/local/autoconf-2.13
472	/usr/local/bin
87568	/usr/local/eaccelerator_cache
4	/usr/local/etc
4	/usr/local/games
172	/usr/local/include
13824	/usr/local/ioncube
4100	/usr/local/lib
4	/usr/local/libexec
36	/usr/local/man
36436840	/usr/local/mysql
5108	/usr/local/nginx
53440	/usr/local/php
4	/usr/local/sbin
2620	/usr/local/share
4	/usr/local/src
900	/usr/local/zend

从返回的命令看出,占用最大的是/usr/local/mysql,继续检查。

[root@localhost ~]#  du -s /usr/local/mysql/var/*

通过检查看到,好多mysql-bin.000XXX的文件,而且都还很大。经过询问度娘发现,此文件为mysql的日志文件,是可以删除的。因为这些日志文
件太大了,对我来说用处不大,索性就直接给关闭了。

[root@localhost ~]# vi /etc/my.cnf 

在log-bin前面加上”#”
