新建虚拟机
创建分区的时候，只是创建swap和/(根)分区

配置ip地址
vim /etc/sysconfig/network-scripts/ifcfg-eth0

/etc/init.d/network restart

磁盘阵列
添加三块硬盘
分区：
fdisk /dev/sdb

fdisk /dev/sdc
n>p>1>enter>enter>p>w
fdisk /dev/sdd

更新分区:
partprobe
创建分区

设置自动挂载：
复制UUID
[root@xxx ~]# mdadm --detail /dev/md1 | grep -i uuid
UUID : 370601ac:e0273cb0:5397b591:5ac11436

创建目录
vim /etc/mdadm.conf
ARRAY /dev/md1 UUID=UUID=420601ac:e0292cb0:5426b591:5ac11574

开机启动
vim /etc/fstab
/dev/md1 /home ext3 defaults,usrquota,grpquota 0 0


[root@xxx ~]# mount -a
[root@xxx ~]# ls /home/
lost+found


新建用户
vim laoyu.sh

#!/bin/bash
for laoyu in laoyu1 laoyu2 laoyu3 laoyu4 laoyu5 laoyu6 laoyu7 laoyu8 laoyu9 laoyu10
do
useradd $laoyu
echo "123456" | passwd --stdin $laoyu
done

sh laoyu.sh

支持配额限制
/dev/md1 on /home type ext3 (rw,usrquota,grpquota)
创建数据文件
quotacheck -avug
[root@xxx ~]# ls /home/
laoyu1 laoyu2 laoyu4 laoyu6 laoyu8 aquota.group lost+found
laoyu10 laoyu3 laoyu5 laoyu7 laoyu9 aquota.user

设置用户配额
edquota -u laoyu1

Disk quotas for user laoyu1 (uid 500):
Filesystem blocks soft hard inodes soft hard
/dev/md1 8 100000 200000 2 0 0
[root@xxx ~]# edquota -p laoyu1 -u laoyu2

[root@xxx ~]# edquota -p laoyu1 -u laoyu8
[root@xxx ~]# edquota -p laoyu1 -u laoyu9
[root@xxx ~]# edquota -p laoyu1 -u laoyu10

开启配额限制
[root@xxx ~]# quotaon -a
[root@xxx ~]# chmod o+w /home/
[root@xxx ~]# su - laoyu1
