1、自建yum仓库，分别为网络源和本地源
一、本地源
[root@centos7 /etc/yum.repos.d]#systemctl start autofs
[root@centos7 /etc/yum.repos.d]#systemctl enabled autofs
[root@centos7 /etc/yum.repos.d]#mkdir /etc/yum.repos.d/bak
[root@centos7 /etc/yum.repos.d]#mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/bak
[root@centos7 /etc/yum.repos.d]#vim /etc/yum.repos.d/base.repo
name=cdrom repo
baseurl=file:///misc/cd
gpgcheck=1
gpgkey=file:///misc/cd/RPM-GPG-KEY-CentOS-7
[epel]
name=EPEL
baseurl=http://mirrors.aliyun.com/epel/$releasever/$basearch
gpgcheck=0
enabled=0
[root@centos7 /etc/yum.repos.d]#yum clean all
[root@centos7 /etc/yum.repos.d]#yum repolist all
二、网络源
[root@centos7 /etc/yum.repos.d]#systemctl stop firewalld
[root@centos7 /etc/yum.repos.d]#systemctl disable
服务器配置
[root@centos7 /etc/yum.repos.d]#yum install httpd -y
[root@centos7 /etc/yum.repos.d]#cd /var/www/html/
[root@centos7 /var/www/html]#mkdir -pv centos/{6,7}/os/x86_64/
[root@centos7 /data]#mount -o loop /data/CentOS-6.9-x86_64-bin-DVD1.iso /var/www/html/centos/6/os/x86_64/
[root@centos7 /var/www/html]#mount /dev/sr0 centos/7/os/x86_64/
客户端配置
[root@centos6 /etc/yum.repos.d]#vim test.repo
[test]
name=base yum
baseurl=http://192.168.17.140/centos/$releasever/os/$basearch/
gpgcheck=1
gpgkey=http://192.168.17.140/centos/$releasever/os/$basearch/RPM-GPG-KEY-CentOS-$releasever
[root@centos6 /etc/yum.repos.d]#yum clean all
[root@centos6 /etc/yum.repos.d]#yum repolist
Loaded plugins: fastestmirror, refresh-packagekit, security

test/primary_db | 4.7 MB 00:00
repo id repo name status
test base yum 6,706
repolist: 6,706
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。
[root@centos7 /app/httpd24]#yum install gcc openssl-devel pcre-devel apr-devel apr-util-devel -y
[root@centos7 /app/httpd24]#./configure \
--prefix=/apps/httpd24 \
--enable-ssl \
--enable-so
[root@centos7 /app/httpd24]#make
[root@centos7 /app/httpd24]#make install
[root@centos7 /app/httpd24]#./bin/apchectl start
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。
[root@centos6 ~]#fdisk /dev/sdb

switch off the mode (command 'c') and change display units to
sectors (command 'u').

[root@centos6 ~]#mkfs.ext4 -b 2048 -L TEST -m 1 /dev/sdb

[root@centos6 ~]#blkid /dev/sdb1

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
[root@centos7 ~]#fdisk /dev/sdb #划分一10G大小的分区，需修改ID（8e），同时增加一个10G大小的磁盘
root@centos7 ~]#lsblk
