cd /etc/yum.repos.d
cp CentOS-Base.repo CentOS-Base.repo.bak
wget -O /etc/yum.repos.d/CentOS-Base.repo https://repo.huaweicloud.com/repository/conf/CentOS-7-reg.repo
yum update -y
yum install -y epel-release
mv epel-testing.repo epel-testing.repo.bak
cp epel.repo epel.repo.bak
sed -i "s/#baseurl/baseurl/g" /etc/yum.repos.d/epel.repo
sed -i "s/metalink/#metalink/g" /etc/yum.repos.d/epel.repo
