今天看服务器探针,吓了我一跳,发现硬盘空间剩余6.2G左右。
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。

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”#”
然后重启服务器,再次查看,就不会在产生日志文件了!
