centos 8 - 安装阿里yum源
<p>首先进入阿里官网：https://developer.aliyun.com/mirror/centos?spm=a2c6h.13651102.0.0.3e221b11AmH9v0</p><p>官网中给出了详细的配置流程，这里为了方便复制了一份：</p>

<p>其中用到了wget，在centos 8 mini版中没有此命令，可以使用curl。</p>
<p>安装上边的操作安装完以后，下载vim，会得到以下提示信息：</p>

<p> </p>
<p> 提示信息中说没有匹配到vim，解决此问题也很简单，将/etc/yum.repos.d/目录下除CentOS-Base.repo其他文件全部删除并执行 yum clean all & yum makecache即可。<img src="https://img2022.cnblogs.com/blog/1240401/202203/1240401-20220307172815700-1483141851.png"></p>
