创建RAID5
首先添加四块磁盘bcde，我这里是每块容量20G，第四块备用
使用fdisk为每块磁盘分一个主分区。容量为20G
fdisk -l|grep "/dev/sd"
分完区之后开始创建RAID5命名为md5
mdadm -Cv /dev/md5 -l5 -n3 -x1 /dev/sd[bcde]1
手动创建RAID配置文件 /etc/mdadm.conf
mdadm -D -s > /etc/mdadm.conf
vim /etc/mdadm.conf
ARRAY /dev/md5 metadata=1.2 spares=2 name=localhost.localdomain:5 UUID=01d880fd:4716cca7:7072e584:e3c07be2 auto=yes

创建物理卷、卷组、逻辑卷
转换成PV
[root@localhost ~]#pvcreate /dev/md5
Physical volume "/dev/md5" successfully created.
转换成VG
[root@localhost ~]# vgcreate -s 8 myvg /dev/md5
Volume group "myvg" successfully created
转换成LV
[root@localhost ~]# lvcreate -L 10G -n mylv myvg
Logical volume "mylv" created.
格式化为xfs系统
[root@localhost ~]# mkfs.xfs /dev/myvg/mylv
meta-data=/dev/myvg/mylv isize=512 agcount=16, agsize=163712 blks

使用xftp工具上传软件包释放到//src/目录
释放到/usr/src/
[root@localhost ~]# tar xf httpd-2.2.17.tar.gz -C /usr/src/

启动Apache
[root@localhost conf]# /usr/local/apache/bin/apachectl start
运行lynx 127.0.0.1 测试 #如没有lynx命令需安装
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
[root@localhost ~]# mount /dev/myvg/mylv /usr/local/apache/htdocs/
[root@localhost ~]# mount -o remount,usrquota,grpquota /usr/local/apache/htdocs/
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
[root@localhost ~]# vim /usr/local/apache/htdocs/index.html
whs
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
[root@ localhost ~]# useradd whs
[root@localhost ~]# vim /etc/fstab

[root@ localhost ~]# quotaon -avug
[root@localhost ~]# setquota -u whs 80000 100000 80 100 /usr/local/apache/htdocs
[root@ localhost ~]# quota -uvs whs

4、构建主从DNS域名解析环境
配置本地yum源

[root@localhost ~]# yum -y install bind
[root@localhost ~]# vim /etc/resolv.conf

从服务器
同样配置yum本地仓库
[root@localhost ~]# yum -y install bind
[root@localhost ~]# cat /etc/resolv.conf
# Generated by NetworkManager
nameserver 192.168.10.11
nameserver 192.168.10.12
[root@localhost ~]# cat /etc/named.conf

};
zone "whs.com" IN {
type slave;
file "slaves/whs.zheng";
masters { 192.168.10.11; };
};
zone "10.168.192.in-addr.arpa" IN {
type slave;
file "slaves/whs.fan";
masters { 192.168.10.11; };
};
[root@localhost ~]# systemctl restart named
主从DNS都可将www.whs.com域名解析为192.168.200.113
