1、自建yum仓库，分别为网络源和本地源
本地源：
1——建立目录，挂载光盘
2——进入到/etc/yum.repos.d/目录下，只保留一个repo结尾的文件，配置最基本的name，baseurl等字段，
3——yum clean all;yum makecache 重新建立缓存
4——验证：yum repolist
[root@centos6 ~]# mount /dev/cdrom /mnt/cdrom/
mount: block device /dev/sr0 is write-protected, mounting read-only
[root@centos6 network-scripts]# cdyum
[root@centos6 yum.repos.d]# ll
total 32
-rw-r--r--. 1 root root 1991 Jun 26 2018 CentOS-Base.repo.bak
-rw-r--r--. 1 root root 647 Jun 26 2018 CentOS-Debuginfo.repo.bak
-rw-r--r--. 1 root root 289 Jun 26 2018 CentOS-fasttrack.repo.bak
-rw-r--r--. 1 root root 630 Jun 26 2018 CentOS-Media.repo.bak
-rw-r--r--. 1 root root 8854 Jun 26 2018 CentOS-Vault.repo.bak
-rw-r--r--. 1 root root 71 Nov 2 21:15 local.repo
[root@centos6 yum.repos.d]# cat local.repo
[local]
name=local_yum
baseurl=file:///mnt/cdrom
gpgcheck=0
enabled=1
[root@centos6 yum.repos.d]#
[root@centos6 yum.repos.d]# yum repolist
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile

repolist: 6,713
网络源
实验环境：
ip1:192.168.80.10——做服务端
ip2:192.168.80.12——做客户端
ip1：
[root@localhost centos7]# yum install -y httpd #安装httpd软件
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
Package httpd-2.4.6-80.el7.centos.x86_64 already installed and latest version
Nothing to do
[root@localhost centos7]# cd /var/www/html/ #进入到httpd存放网页数据的目录中，新建若干文件夹，然后将对应版本的iso文件挂载到对应目录，
[root@localhost html]# ll

[root@localhost html]# mount /dev/cdrom centos7/
[root@localhost html]# systemctl start httpd
[root@localhost html]# systemctl stop firewalld
# 启动httpd，关闭防火墙
ip2：
打开浏览器输入ip1可以看到对应的文件夹，如下图所示：
# 编辑yum源的配置文件，输入以下内容
[root@centos6 yum.repos.d]# vim http_yum.repo
[root@centos6 yum.repos.d]# cat http_yum.repo
[http_yum]
name=this is a http yum
baseurl=http://192.168.80.10/centos7
gpgcheck=0
enabled=1
[root@centos6 yum.repos.d]#
# 刷新，重建缓存即可
[root@centos6 yum.repos.d]# yum clean all;yum makecache

2、编译安装http2.4，实现可以正常访问，并将编译步骤和结果提交。
# 下载源码包并解压
[root@localhost data]# wget http://mirror.bit.edu.cn/apache/httpd/httpd-2.4.41.tar.gz

3、创建一个2G的文件系统，块大小为2048byte，预留1%可用空间,文件系统 ext4，卷标为TEST，要求此分区开机后自动挂载至/test目录，且默认有acl挂载选项
# 新加一块虚拟硬盘
[root@localhost ~]# echo '- - -' > /sys/class/scsi_host/host0/scan
[root@localhost ~]# lsblk

4、创建一个至少有两个PV组成的大小为20G的名为testvg的VG;要求PE大小 为16MB, 而后在卷组中创建大小为5G的逻辑卷testlv;挂载至/users目录
# 新加一块硬盘，20G，然后分两个10G的区
[root@localhost ~]# fdisk /dev/sdc
