一、关闭selinux
[root@6 home]# sestatus -v SELinux status: disabled 示例：临时关闭 [root@6 home]# setenforce 0 示例：永久关闭 [root@6 home]# vi /etc/selinux/config SELINUX=disabled
二、在/etc/fstab中添加usrquota、grpquota挂载参数
/dev/mapper/VolGroup-lv_home /home ext4 defaults,usrquota,grpquota 1 2
三、使用quotacheck扫描创建配置文件
# quotacheck －avug
四、使用edquota编辑配置文件
编辑指定用户／组的配额 # edquota -u username／-g groupname 更改超额宽限期 # edquota -t
五、开启／关闭quota
全部开启／关闭 # quotaon/quotaoff -avug 指定user／group关闭 # quotaon/quotaoff -u USERNAME/-g GROUPNAME
六、查看配额报告／状态
[root@6 home]# repquota -avugs *** Report for user quotas on device /dev/mapper/VolGroup-lv_home Block grace time: 7days; Inode grace time: 7days Block limits File limits User used soft hard grace used soft hard grace ---------------------------------------------------------------------- root -- 20 0 0 2 0 0 test -- 16 0 0 4 0 0 Statistics: Total blocks: 7 Data blocks: 1 Entries: 2 Used average: 2.000000 *** Report for group quotas on device /dev/mapper/VolGroup-lv_home Block grace time: 7days; Inode grace time: 7days Block limits File limits Group used soft hard grace used soft hard grace ---------------------------------------------------------------------- root -- 20 0 0 2 0 0 test -- 16 0 0 4 0 0 Statistics: Total blocks: 7 Data blocks: 1 Entries: 2 Used average: 2.000000
