3、创建RAID 5
[root@localhost ~]# mdadm -C /dev/md5 -l 5 -n 3 /dev/sd[bcd]1
mdadm: Defaulting to version 1.2 metadata
mdadm: array /dev/md5 started.
[root@localhost ~]# mkfs.xfs /dev/md5

7、格式化逻辑卷
[root@localhost ~]# mkfs.xfs /dev/myvg/mylv
log stripe unit (524288 bytes) is too large (maximum is 256KiB)
log stripe unit adjusted to 32KiB
meta-data=/dev/myvg/mylv isize=256 agcount=16, agsize=491392 blks

8、安装apache
[root@localhost ~]# yum -y install gcc gcc-c++
[root@localhost ~]# yum -y install gcc gcc-c++
[root@localhost ~]#tar xf httpd-2.2.17.tar.gz -C /usr/src

[root@localhost ~]#/usr/local/apache/bin/apachectl start
[root@localhost ~]yum -y install lynx
[root@localhost ~]lynx 127.0.0.1
9、挂载[root@localhost ~]# mount -O usrquota,grpquota /dev/myvg/mylv /usr/local/apache/htdocs/
[root@localhost ~]# df -Th
文件系统 类型 容量 已用 可用 已用% 挂载点
/dev/mapper/centos-root xfs 28G 4.8G 23G 18% /

10、磁盘配额
[root@localhost ~]# quotacheck -auvg
quotacheck: Skipping /dev/mapper/myvg-mylv [/data]
quotacheck: Skipping /dev/mapper/vg-lv [/usr/local/apache/htdocs]
quotacheck: Cannot find filesystem to check or filesystem not mounted with quota option.
[root@localhost ~]# quotaon -avug
[root@localhost ~]# quotacheck -auvg
quotacheck: Skipping /dev/mapper/myvg-mylv [/data]
quotacheck: Skipping /dev/mapper/vg-lv [/usr/local/apache/htdocs]
