阿里云centos yum报错 - Status code: 404 for httphotoshop://mirrors.aliyun.com/centos/centos/8/AppStream/x86_6

https://developer.aliyun.com/mirror/centos?spm=a2c6h.13651102.0.0.3e221b11ON0Hhn
官网直接一行代码搞定
**错误：
yum install maven
Repository epel is listed more than once in the configuration
CentOS Linux 8 - AppStream 17 MB/s | 18 MB 00:01
CentOS Linux 8 - BaseOS 7.3 kB/s | 2.3 kB 00:00
Errors during downloading metadata for repository ‘baSEO（(Search Engine Optimization)）s’:

• Status code: 404 for https://mirrors.aliyun.com/centos/8/BaseOS/x86_64/os/repodata/repomd.xml (IP: 39.96.118.192)
  Error: Failed to download metadata for repo ‘baSEO（(Search Engine Optimization)）s’: Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried**

主要是镜像库丢了

https://mirrors.aliyun.com/centos/

修改报错的文件 在目录/etc/yum.repos.d 下面找

修改baseurl

要保证阿里云仓库数据

比如这个就没有

然后我把 代表8的这个"$releasever"改成了$releasever-stream
