启用quota:在fstab中修改
/dev/xvda3 /home ext3 defaults,usrquota,grpquota 1 1
重新挂载:
umount /home
mount -a
mount -o remount /home
新建两个用户test test2:
groupadd test
useradd -m -g test test
useradd -m -g test test2
passwd test
passwd test2
扫瞄磁盘的使用者使用状况,并产生重要的 aquota.group 与 aquota.user:
quotacheck -a
启动配额:
quotaon -aug
修改配额:
# edquota -u test
Disk quotas for user test (uid 500):
Filesystem blocks soft hard inodes soft hard
/dev/xvda3 120 100 120 18 15 18
filesystem:指定分区
blocks: 当前用户已用的磁盘容量,这个是quota自动算出来的,不需要修改
soft: 允许用户超过这个值,但必须在宽限时间内降回这个容量范围内
hard: 绝对不能超过的上限
inodes: 当前使用的inode数,也是quota自动计算的,不需要修改
修改宽限时间:
# edquota -t
Grace period before enforcing soft limits for users:
Time units may be: days, hours, minutes, or seconds
Filesystem Block grace period Inode grace period
/dev/xvda3 1days 1days
宽限时间:在超过软极限,而没有超过硬极限所允许超过软极限的时间。
