CentOS6无法使用yum问题

方法一：一键修复

sed -i "s|enabled=1|enabled=0|g" /etc/yum/pluginconf.d/fastestmirror.conf

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

curl -o /etc/yum.repos.d/CentOS-Base.repo https://www.xmpan.com/Centos-6-Vault-Aliyun.repo

yum clean all

yum makecache

 

方法二：手动修复

①关闭fastestmirrors

用vi打开fastestmirror.conf文件

vi /etc/yum/pluginconf.d/fastestmirror.conf

修改enable的值，使其为零

enable=0

执行如下命令

sed -i "s|enabled=1|enabled=0|g" /etc/yum/pluginconf.d/fastestmirror.conf

②修改repo

把之前的repo挪入备份

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak

替换为官方Vault源（海外服务器）

curl -o /etc/yum.repos.d/CentOS-Base.repo https://www.xmpan.com/Centos-6-Vault-Official.repo

或者替换为阿里云Vault镜像（国内服务器）

curl -o /etc/yum.repos.d/CentOS-Base.repo https://www.xmpan.com/Centos-6-Vault-Aliyun.repo
