编辑/etc/fstab文件

用vi编辑器打开/etc/fstab文件，对/home所在行进行修改，增加命令选项userquota 和grpquota

重启系统

重启系统可使系统读取/etc/fstab文件的内容，重新挂载

创建配额文件

执行命令quotacheck命令

[root@localhost ~]# quotacheck -avgu

quotacheck: Your kernel probably supports journaled quota but you are not using it. Consider switching to journaled quota to avoid running quotacheck after an unclean shutdown.
quotacheck: Scanning /dev/sda3 [/home] done
quotacheck: Cannot stat old user quota file: No such file or directory
quotacheck: Cannot stat old group quota file: No such file or directory
quotacheck: Cannot stat old user quota file: No such file or directory
quotacheck: Cannot stat old group quota file: No such file or directory
quotacheck: Checked 7 directories and 3 files
quotacheck: Old file not found.
quotacheck: Old file not found.

查看/home目录

root@localhost ~]# cd /home
[root@localhost home]# ls
aquota.group  aquota.user  fly  lost+found

执行edquota文件

edquota -u user1

Disk quotas for user fly (uid 500): Filesystem blocks soft hard inodes soft hard /dev/sda3 32 10240 15360 8 0 0

执行

[root@localhost home]# edquota -u fly

[root@localhost home]# edquota -u fly

[root@localhost home]# useradd horse

[root@localhost home]# edquota -p fly horse

[root@localhost home]# groupadd user
[root@localhost home]# gpasswd -a fly user
Adding user fly to group user
[root@localhost home]# gpasswd -a horse  user
Adding user horse to group user
[root@localhost home]# edquota -g user

启动配额管理

[root@localhost home]# quotaon -aguv

/dev/sda3 [/home]: group quotas turned on
/dev/sda3 [/home]: user quotas turned on

查看配额情况：

[root@localhost home]#  quota fly
Disk quotas for user fly (uid 500):
     Filesystem  blocks   quota   limit   grace   files   quota   limit   grace
      /dev/sda3      32   10240   15360               8       0       0

关闭配额管理

[root@localhost new]# quotaoff -aguv
/dev/sda3 [/home]: group quotas turned off
/dev/sda3 [/home]: user quotas turned off
