1、自建yum仓库，分别为网络源和本地源
[root@localhost yum.repos.d]# mv *.repo /data/repobak //原yum源备份
[root@localhost yum.repos.d]# vim aliyun.repo //配置网络源
[alinyun]
baseurl=https://mirrors.aliyun.com/centos/7/os/x86_64/
name=aliyun repo
gpgcheck=0
enabled=1
[root@localhost ~]# systemctl start autofs //挂载本地源文件
[root@localhost ~]# ll /misc/cd/
total 1656

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@localhost data]# tar xvf httpd-2.4.25.tar.bz2 //将httpd源码包解压缩
[root@localhost httpd-2.4.25]# yum install gcc openssl-devel pcre-devel apr-devel apr-util-devel -y //安装编译软件及依赖包
[root@localhost httpd-2.4.25]#./configure --enable-ssl --enable-so //配置安装需要的组件
[root@localhost httpd-2.4.25]# ll Makefile //生成make文件
-rw-r--r-- 1 root root 10622 Jul 17 16:07 Makefile
[root@localhost httpd-2.4.25]# make -j 4 //make多核编译
[root@localhost httpd-2.4.25]# make install //安装
[root@localhost bin]# ./apachectl //到程序安装目录执行启动程序
[root@localhost bin]# curl http://192.168.58.129 //可以正常访问
<html><body><h1>It works!</h1></body></html>
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@localhost bin]# echo '- - -' > /sys/class/scsi_host/host0/scan //检索出硬盘
[root@localhost bin]# lsblk
