Centos中执行yum update或yum install 时报Error: Cannot find a valid baseurl for repo: base错误

执行命令报错如下图：

执行命令报如下错：

Loaded plugins: fastestmirror, refresh-packagekit, security
Setting up Update Process
Determining fastest mirrors
YumRepo Error: All mirror URLs are not using ftp, http[s] or file.
Eg. Invalid release/repo/arch combination/
removing mirrorlist with no valid mirrors: /var/cache/yum/x86_64/6/base/mirrorlist.txt
Error: Cannot find a valid baseurl for repo: base

这是因为在CentOS 6在2020年11月30过后，就不在维护了，使用如下方法解决：

1. 进入/etc/yum.repos.d/

# cd /etc/yum.repos.d/

1. 编辑 CentOS-Base.repo

# 先备份
# cp CentOS-Base.repo CentOS-Base.repo.old

# 编辑
# vim CentOS-Base.repo

1. 编辑如下几个块

• [base]
• [updates]
• [extras]
• 修改内容如下：替换原有的

• [base]
  name=CentOS-$releasever - Base
  # mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra
  # baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
  baseurl=https://vault.centos.org/6.10/os/$basearch/
  gpgcheck=1
  gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
  
  # released updates
  [updates]
  name=CentOS-$releasever - Updates
  # mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates&infra=$infra
  # baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/
  baseurl=https://vault.centos.org/6.10/updates/$basearch/
  gpgcheck=1
  gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
  
  # additional packages that may be useful
  [extras]
  name=CentOS-$releasever - Extras
  # mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras&infra=$infra
  # baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/
  baseurl=https://vault.centos.org/6.10/extras/$basearch/
  gpgcheck=1
  gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

   

• 清楚缓存

• # yum clean all
  

• 重新执行更新

• # yum update
