解决 CentOS Cannot find a valid baseurl for repo
参考:Fix "Cannot find a valid baseurl for repo" in CentOS - DEV Community
背景
由于 CentOS 7 镜像被移动到 vault。当执行 yum 时,会报错“Cannot find a valid baseurl for repo: base/7/x86_64”。
解决
将/etc/yum.repos.d/CentOS-Base.repo
中的原有内容删除,将其设置为如下内容:
# CentOS-Base.repo # # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and # geographically close to the client. You should use this for CentOS updates # unless you are manually picking other mirrors. # # If the mirrorlist= does not work for you, as a fall back you can try the # remarked out baseurl= line instead. # # [base] name=CentOS-$releasever - Base mirrorlist=http://vault.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra baseurl=http://vault.centos.org/centos/$releasever/os/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 #released updates [updates] name=CentOS-$releasever - Updates mirrorlist=http://vault.centos.org/?release=$releasever&arch=$basearch&repo=updates&infra=$infra baseurl=http://vault.centos.org/centos/$releasever/updates/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 #additional packages that may be useful [extras] name=CentOS-$releasever - Extras mirrorlist=http://vault.centos.org/?release=$releasever&arch=$basearch&repo=extras&infra=$infra baseurl=http://vault.centos.org/centos/$releasever/extras/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 #additional packages that extend functionality of existing packages [centosplus] name=CentOS-$releasever - Plus mirrorlist=http://vault.centos.org/?release=$releasever&arch=$basearch&repo=centosplus&infra=$infra baseurl=http://vault.centos.org/centos/$releasever/centosplus/$basearch/ gpgcheck=1 enabled=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
更改好后执行sudo yum update -y
即可。
