1、自建yum仓库，分别为网络源和本地源
将镜像挂载到本地
#mount -t iso9660 /opt/CentOS-7-x86_64-DVD-1611.iso /var/www/html/centos73/
#df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 408G 21G 367G 6% /
devtmpfs 32G 0 32G 0% /dev
tmpfs 32G 0 32G 0% /dev/shm
tmpfs 32G 1.8G 30G 6% /run
tmpfs 32G 0 32G 0% /sys/fs/cgroup
/dev/sda1 190M 99M 78M 57% /boot
tmpfs 6.3G 0 6.3G 0% /run/user/0
/dev/sdb 9.6T 7.8T 1.3T 86% /data1
/dev/loop0 4.1G 4.1G 0 100% /var/www/html/centos73
本地源
#cat >> /etc/yum.repos.d/local.repo<< EOF
[local]
name=localmedia
baseurl=file:///var/www/html/centos73
gpgcheck=0
enabled=1
EOF
网络源
将镜像挂载到httpd服务的路径下面
#mount -t iso9660 /opt/CentOS-7-x86_64-DVD-1611.iso /var/www/html/centos73/
#cat >> /etc/yum.repos.d/web.repo<< EOF
[local]
name=web
baseurl=http://10.21.12.33:8080/centos73
gpgcheck=0
enabled=1
EOF
查看yum源
# yum clean all && yum repolist
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
repo id repo name status
local localmedia 3,831
web webyum 3,831
repolist: 7,662
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apr，apr-util，httpd及安装编译包
#wget https://mirrors.tuna.tsinghua.edu.cn/apache/httpd/httpd-2.4.38.tar.gz
#wget https://mirrors.tuna.tsinghua.edu.cn/apache/apr/apr-1.6.5.tar.gz
#wget https://mirrors.tuna.tsinghua.edu.cn/apache/apr/apr-util-1.6.1.tar.gz
#yum -y install pcre-devel expat-devel openssl-devel gcc-c++ bzip2 gcc make
安装apr
#tar -xf apr-1.6.5.tar.gz
#cd apr-1.6.5
#./configure --prefix=/usr/local/apr/
#make && make install
安装apr-util
#tar -xf apr-util-1.6.1.tar.gz
#cd apr-util-1.6.1
#./configure --prefix=/usr/local/apr-util/ --with-apr=/usr/local/apr/
#make && make install
安装httpd
#tar -xf httpd-2.4.38.tar.gz
#cd httpd-2.4.38
#./configure --prefix=/usr/local/httpd/ --with-apr=/usr/local/apr/ --with-apr-util=/usr/local/apr-util/
#make && make install
#cp /usr/local/httpd/bin/apachectl /etc/init.d/httpd
#sed -i s/'#ServerName www.example.com:80'/'ServerName www.example.com:80'/ /usr/local/httpd#/conf/httpd.conf
#/etc/init.d/httpd start
setenforce 0
systemctl stop firewalld
访问主机ip正常显示则成功

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
fidisk创建2G的分区
#fdisk /dev/sdo

查看UUID及写入配置文件
# blkid /dev/sdo1
/dev/sdo1: LABEL="TEST" UUID="f72b9bbb-64cc-4096-9b2d-5d954ecedf1b" TYPE="ext4"
echo 'UUID="f72b9bbb-64cc-4096-9b2d-5d954ecedf1b" /opt/xx ext4 defaults,acl 0 0' >> /etc/fstab
验证挂载
#mount -av|grep sdo
/dev/sdo1 on /opt/xx type ext4 (rw,acl)
#df -h|grep /opt/xx
/dev/sdo1 2.0G 9.1M 1.9G 1% /opt/xx
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
查看准备的2个10G分区
# fdisk -l /dev/sdo|grep sdo*

/dev/sdo1 1 262 2104483+ 83 Linux
/dev/sdo2 263 1568 10490445 83 Linux
/dev/sdo3 1569 2874 10490445 83 Linux

查看uuid，方便写入配置文件挂载
# blkid /dev/testvg/testlv
/dev/testvg/testlv: UUID="4c71433e-28aa-437b-9f24-fb0f132d4b6f" TYPE="ext4"
创建挂载路径及手动挂载
# mkdir /users
# mount /dev/testvg/testlv /users
# df -h|grep users
/dev/mapper/testvg-testlv 4.8G 10M 4.6G 1% /users
写入配置文件
#echo 'UUID="4c71433e-28aa-437b-9f24-fb0f132d4b6f" /users ext4 defaults 0 0' >> /etc/fstab
