CentOS 7 配置私服仓库源 - yum、epel

1. 备份原有yum源

mkdir -p /etc/yum.repos.d/backup
mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/backup

2. 配置仓库地址为临时环境变量

# nexus3代理的地址 在neuxs上直接copy
REPO_URL=https://mirrors.ochaly.com/repository/yum-public/

3. 配置yum源

cat > /etc/yum.repos.d/nexus-yum.repo << EOF
[base]
name=CentOS-Base-Nexus
failovermethod=priority
baseurl=$REPO_URL\$releasever/os/\$basearch/
enabled=1
gpgcheck=1
gpgkey=$REPO_URL\RPM-GPG-KEY-CentOS-7

# released updates

cat > /etc/yum.repos.d/nexus-epel.repo << EOF
[epel]
name=Extra Packages for Enterprise Linux - $basearch
