修复yum无法安装、更新等问题

linux admin 27℃

CentOS 6已经随着2020年11月的结束进入了EOL(Reaches End of Life),不过有一些老设备依然需要支持,CentOS官方也给这些还不想把CentOS 6扔进垃圾堆的用户保留了最后一个版本的镜像,只是这个镜像不会再有更新了

官方便在12月2日正式将CentOS 6相关的软件源移出了官方源,随之而来逐级镜像也会陆续将其删除。

1、首先把fastestmirrors关了:

#编辑
vi /etc/yum/pluginconf.d/fastestmirror.conf
#修改
enable=0
#或者执行以下命令
sed -i "s|enabled=1|enabled=0|g" /etc/yum/pluginconf.d/fastestmirror.conf

2、把之前的repo备份:

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

3、查看CentOS版本:

cat  /etc/redhat-release

4、更改源镜像为阿里云镜像,版本设置为系统的版本:
vim /etc/yum.repos.d/CentOS-Base.repo

# 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-6.5 - Base
baseurl=http://mirrors.aliyun.com/centos-vault/6.5/os/x86_64/
gpgcheck=1
gpgkey=http://mirrors.aliyun.com/centos-vault/RPM-GPG-KEY-CentOS-6
 
[updates]
name=CentOS-6.5 - Updates
baseurl=http://mirrors.aliyun.com/centos-vault/6.5/updates/x86_64/
gpgcheck=1
gpgkey=http://mirrors.aliyun.com/centos-vault/RPM-GPG-KEY-CentOS-6
 
[extras]
name=CentOS-6.5 - Extras
baseurl=http://mirrors.aliyun.com/centos-vault/6.5/extras/x86_64/

gpgkey=http://mirrors.aliyun.com/centos-vault/RPM-GPG-KEY-CentOS-6
 
[centosplus]
name=CentOS-6.5 - Plus
baseurl=http://mirrors.aliyun.com/centos-vault/6.5/centosplus/x86_64/
gpgcheck=1
enabled=0
gpgkey=http://mirrors.aliyun.com/centos-vault/RPM-GPG-KEY-CentOS-6
 
[contrib]
name=CentOS-6.5 - Contrib
baseurl=http://mirrors.aliyun.com/centos-vault/6.5/contrib/x86_64/
gpgcheck=1
enabled=0
gpgkey=http://mirrors.aliyun.com/centos-vault/RPM-GPG-KEY-CentOS-6

5、更新yum:

yum update

完成!
