为新装的Centos 7X更换源，升级VIM失败，待解决

CentOS 7X使用阿里云CentOS的yum源

1.备份原有repo文件

#cd /etc/yum.repos.d

#mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

2.下载repo文件

# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

提示：-bash: wget: command not found

明显没有安装wget软件包，好吧，接着搞。

下载wget的软件包

https://mirrors.aliyun.com/centos/7.6.1810/os/x86_64/Packages/wget-1.14-18.el7.x86_64.rpm

安装：

rpm -ivh wget-1.14-18.el7.x86_64.rpm

接着回到步骤 2

# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

 vim升级失败，待解决
