CentOS8.4配置本地YUM源

一.加载安装光盘镜像

 # mkdir /mnt/cdrom/ 

 # mount /dev/cdrom /mnt/cdrom/  

二.拷贝到本地

 # mkdir /opt/yum/ 

 # cd /mnt/cdrom/ 

 # cp -R AppStream/ BaseOS/ /opt/yum/  

三.配置本地yum源

 # cd /etc/yum.repos.d/ 

配置appstream

 # vim CentOS-Linux-AppStream.repo 

[appstream]
name=CentOS Linux $releasever - AppStream
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=AppStream&infra=$infra
#baseurl=http://mirror.centos.org/$contentdir/$releasever/AppStream/$basearch/os/
baseurl=file:///opt/yum/AppStream/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial

配置baseos

 # vim CentOS-Linux-BaseOS.repo 

[baseos]
name=CentOS Linux $releasever - BaseOS
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=BaseOS&infra=$infra
#baseurl=http://mirror.centos.org/$contentdir/$releasever/BaseOS/$basearch/os/
baseurl=file:///opt/yum/BaseOS/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial

关闭extras，enabled设为0

 # vim CentOS-Linux-Extras.repo 

[extras]
name=CentOS Linux $releasever - Extras
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras&infra=$infra
#baseurl=http://mirror.centos.org/$contentdir/$releasever/extras/$basearch/os/
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial

四.验证

 # yum clean all 

 # yum list 

 

 五.卸载光盘镜像

 # umount /dev/cdrom
