磁盘管理综合测试题

实验需求：

1、用户需把/dev/myvg/mylv逻辑卷以支持磁盘配额的方式挂载到网页目录下

2、在网页目录下创建测试文件index.html，内容为用户名称，通过浏览器访问测试

3、创建用户账户，对LVM配置磁盘配额限制用户磁盘容量为软限制80M；硬限制100M、文件数量软限制为80个；硬限制为100个。

 实验拓扑：

实验步骤：

[root@localhost ~]# mdadm -Cv /dev/md5 -l5 -n3 /dev/sd[bcd]1

[root@localhost ~]# pvcreate /dev/md5

Physical volume "/dev/md5" successfully created.

root@localhost ~]# vgcreate myvg /dev/md5

Volume group "myvg" successfully created

root@localhost ~]# lvcreate -L 5G -n mylv myvg

Logical volume "mylv" created.

root@localhost ~]# mkfs.xfs /dev/myvg/mylv

1：[root@localhost ~]# mount /dev/myvg/mylv /usr/local/httpd/htdocs/

2：[root@localhost httpd-2.2.17]# /usr/local/httpd/htdocs/bin/apachectl start

[root@localhost httpd-2.2.17]# lynx 192.168.1.155

[root@localhost htdocs]# vim index.html

[root@localhost htdocs]# ls

index.html

[root@localhost htdocs]# systemctl stop firewalld.service

[root@localhost htdocs]# setenforce 0

 

3:[root@localhost ~]# mount /dev/myvg/mylv /usr/local/httpd/htdocs/

[root@localhost ~]# mount -a

[root@localhost ~]# vim /etc/fstab

[root@localhost ~]# quotacheck -avug

root@localhost ~]# quotaon -a
