我用一般用户登录centos，登录时显示的信息。
网上说chmod 1777 /tmp ，但是，实际我的/tmp的权限是对的。drwxrwxrwt  17 root root  4096 07-15 09:39 tmp
还有人说改chmod u+wr /home/username/,Xauthority,不过我根本就没有这个目录呢。
我用df -h 显示的
文件系统              容量  已用可用已用% 挂载点
/dev/sda5             7.6G  7.3G     0 100% /
/dev/sda7             4.7G  1.4G  3.1G  32% /home
/dev/sda3              99M   12M   83M  12% /boot
tmpfs                1009M     0 1009M   0% /dev/shm
/下面的全部用完了，我 ll -h /之显示199k
情大家帮忙解决下

根目录满了，清理一下/tmp、/var/tmp、/var/log等几个地方，能把磁盘用成这样可能是一些临时文件没清掉吧
