1、自建yum仓库，分别为网络源和本地源
配置网络源：
阿里云yum源链接：https://developer.aliyun.com/mirror/centos?spm=a2c6h.13651102.0.0.3e221b11Al1i4w
备份：
# mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
# yum makecache
# yum repolist
配置本地源：
[root@www ~]# mount /dev/cdrom /mnt/
[root@www ~]# rm -rf /etc/yum.repos.d/*
[root@www ~]# vim local.repo
[centos]
name=centos
baseurl=file:///mnt
gpgcheck=0
enabled=1
[root@www yum.repos.d]# yum clean all
Loaded plugins: fastestmirror, langpacks
Cleaning repos: centos
Cleaning up list of fastest mirrors
Other repos take up 125 M of disk space (use --verbose for details)
[root@www yum.repos.d]# yum repolist

repo id repo name status
centos centos 4,067
repolist: 4,0672、 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。
