centos8 yum 相关国内镜像仓库弃用(deprecated)

今天centos8使用yum安装软件时报错。

- Curl error (28): Timeout was reached for http://mirrors.aliyuncs.com/centos/8/BaseOS/x86_64/os/repodata/repomd.xml [Connection timed out after 30001 milliseconds]
- Status code: 404 for https://mirrors.aliyun.com/centos/8/BaseOS/x86_64/os/repodata/repomd.xml (IP: 42.81.213.224)

查看一下：https://mirrors.aliyun.com/centos/8/readme

This directory (and version of CentOS) is deprecated.

由于只是安装tcpdump,目前临时解决方案调整了一下安装源。

# echo "8-stream" > /etc/yum/vars/releasever
# yum clean all
# yum makecache

如果未使用国内镜像也可以手工更新到 vault.centos.org 镜像地址

# cd /etc/yum.repos.d/
# sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
# sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*
# yum update -y

镜像地址更新成功后可以升级到centos stream。

# dnf install centos-release-stream -y --allowerasing
# dnf distro-sync -y

2022/03/04 阿里云更新了镜像地址， 后续可能要考虑开发环境调整了。
