yum安装时出现：Cannot retrieve metalink for repository: epel. Please verify its path and try again

解决方案 ：

cd /etc/yum.repos.d/epel.repo
把baseurl那一行取消注释
把mirrorlist那一行加上注释

打开/etc/yum.repos.d/epel.repo，将

1. [epel]
2. name=Extra Packages for Enterprise Linux 6 - $basearch
3. #baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
4. mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch

修改为

1. [epel]
2. name=Extra Packages for Enterprise Linux 6 - $basearch
3. baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
4. #mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch

再清理源，重新安装

1. yum clean all
2. yum install -y 需要的包

完结

比如我是卡在了yum install -y python-pip，接下来再yum下载的时候就成功了。
