centos 6.8 yum源不可用安装报YumRepo Error: All mirror URLs are not using ftp, http[s] or file

问题场景

今天在给环境装插件的时候，yum 提示报错如图：

 

 

 

 经过查询发现是自己的 yum 源有问题

处理方案  

//删除yum.repos.d目录下所有文件
rm -f /etc/yum.repos.d /*    
// 重新下载
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo 

下载完成后，CentOS-Base.repo文件内的baseurl依然不可使用，将其替换成https://vault.centos.org/6.8。例如：

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
