1、自建yum仓库，分别为网络源和本地源
1）备份现有的yum源
mkdir /etc/yum.repo.d/bak
mv /etc/yum.repo.d/*.repo /etc/yum.repo.d/bak2）创建yum源配置文件
vim /etc/yum.repo.d/base.repo
[base]
name=cdrom base
baseurl=file:///mnt/rhel
gpgcheck=0
[epel]
name=aliyun epel
baseurl=http://mirrors.aliyun.com/epel/$releasever/$basearch/
gpgcheck=0
enabled=1 3）挂载ios文件
把ios文件挂载到/mnt/rhel上mount /data/rhel-server-7.4-x86_64-dvd.iso /mnt/rhel
4) 查看yum仓库
[18:45:10 root@centos7_6 jiangjingqun]# yum repolist all
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
repo id repo name status
base cdrom base enabled: 4,021
epel/7/x86_64 aliyun epel enabled: 13,415
repolist: 17,436
[18:45:17 root@centos7_6 jiangjingqun]# 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。
1）、导入源码 httpd-2.4.25.tar.bz2 ，解压；
可以使用rz命令上传源码包tar -xvf httpd-2.4.25.tar.bz2
2）进入解压文件开始编译
执行./configure命令
[14:04:30 root@centos7_6 httpd-2.4.25]# cd httpd-2.4.25

执行 make -j 4
执行 make install
查看编译后的目录：
