RHEL 8配置yum源

1. 挂载光盘镜像配置本地yum源
先移走系统默认的repo文件

cd /etc/yum.repos.d/
mkdir repobak
mv *.repo repobak/


2. 挂载本地光盘镜像

mkdir /mnt/cdrom
mount -t iso9660 /soft/rhel-8.2-x86_64-dvd.iso /mnt/cdrom


3. 编辑本地yum源repo文件

vi CentOS-LocalMedia.repo

[local-BaseOS]
name=CentOS-BaseOS
baseurl=file:///mnt/cdrom/BaseOS
gpgcheck=0
enabled=1

[local-AppStream]
name=CentOS-AppStream
baseurl=file:///mnt/cdrom/AppStream
gpgcheck=0
enabled=1


4. 生成本地缓存和测试

dnf clean all
dnf makecache
dnf install iotop -y

1. 阿里云yum源

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-8.repo

或者

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-8.repo
sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo


2. 阿里云epel

yum install -y https://mirrors.aliyun.com/epel/epel-release-latest-8.noarch.rpm
sed -i 's|^#baseurl=https://download.fedoraproject.org/pub|baseurl=https://mirrors.aliyun.com|' /etc/yum.repos.d/epel*
sed -i 's|^metalink|#metalink|' /etc/yum.repos.d/epel*


4. fedora yum源(代替阿里云)

yum install -y https://download-ib01.fedoraproject.org/pub/epel/8/Everything/x86_64/Packages/e/epel-release-8-9.el8.noarch.rpm


3. 生成缓存和测试

yum makecache 
yum search bashtop

1. 挂载DVD

mount -t iso9660 /soft/CentOS-7-x86_64-DVD-1804.iso /mnt/cdrom/

2. 禁用网络yum源

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


3. vi CentOS-Media.repo

[centos-local]
name=CentOS-$releasever - Media
baseurl=file:///mnt/cdrom/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7


4. yum加载源

yum clean all
