使用yum install vim时，出现HTTP Error 404 - Not Found的提示，具体如下：
yum install vim
http://mirrors.aliyun.com/non-supported/rhel/7/x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found
解决思路就是卸载重新安装，具体流程如下：
# 进入yum cd /etc/yum.repos.d # 移除 rm *.*
# 查看yum版本 [root@192 yum.repos.d]# rpm -qa yum yum-3.4.3-168.el7.centos.noarch # 卸载yum安装包 rpm -qa yum yum-3.4.3-168.el7.centos.noarch # 卸载安装组件 rpm -qa | grep yum | xargs rpm -e --nodeps rpm -qa yum
