安装epel-release

原来的文件内容如下：

[root@VM-4-12-opencloudos ~]# cat /etc/yum.repos.d/epel.repo 
[epel]
name=Extra Packages for OpenCloudOS $releasever - $basearch
baseurl=http://mirrors.tencent.com/epel/8/Everything/$basearch/
        http://mirrors.tencentyun.com/epel/8/Everything/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-8

[epel-debuginfo]
name=Extra Packages for OpenCloudOS $releasever - $basearch - Debug
baseurl=http://mirrors.tencent.com/epel/8/Everything/$basearch/debug/
        http://mirrors.tencentyun.com/epel/8/Everything/$basearch/debug/

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-8
gpgcheck=1

[epel-source]

用如下命令自动替换：

sed -e 's!^metalink=!#metalink=!g' \
    -e 's!^#baseurl=!baseurl=!g' \
    -e 's!https\?://download\.fedoraproject\.org/pub/epel!https://mirrors.tuna.tsinghua.edu.cn/epel!g' \
    -e 's!https\?://download\.example/pub/epel!https://mirrors.tuna.tsinghua.edu.cn/epel!g' \
    -i /etc/yum.repos.d/epel{,-testing}.repo

修改结果如下：

给yum配置代理

修改/etc/yum.conf文件

vim /etc/yum.conf

增加一行：
