centos7.X设置本地YUM源
下面以centos7.5为例子
1、首先把centos7.5的iso镜像文件拷贝/home下
iso镜像可到：
http://mirrors.aliyun.com/centos-vault/7.5.1804/isos/x86_64/
下载：CentOS-7-x86_64-DVD-1804.iso
1.1.创建以下目录：
|
1 2 3 4 |
mkdir /home/yum-iso mkdir /home/yum/ |
1.2.把iso系统解压到指定路径下：
|
1 2 |
mount -o loop CentOS-7-x86_64-DVD-1804.iso /home/yum-iso |
1.3.把iso解压到yum-iso文件拷贝到yum路径下
|
1 2 |
scp -r /home/yum-iso/ /home/yum |
1.4.查看拷贝情况
|
1 2 |
ll yum |
2、进入yum.repos.d文件路径下
|
1 2 |
cd /etc/yum.repos.d/ |
2.1.用tar打包备份文件
|
1 2 |
tar -zcvf repo-bk.tar.gz CentOS-* |
2.2.rm -f 删掉不必要的文件
|
1 2 |
rm -f CentOS-Base.repo CentOS-CR.repo CentOS-Debuginfo.repo CentOS-fasttrack.repo CentOS-Sources.repo CentOS-Vault.repo |
3.配置本地CentOS-Media.repo
vi CentOS-Media.repo
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
#修改的内容 # CentOS-Media.repo # # This repo can be used with mounted DVD media, verify the mount point for # CentOS-7. You can use this repo and yum to install items directly off the # DVD ISO that we release. # # To use this repo, put in your DVD and use it with the other repos too: # yum --enablerepo=c7-media [command] # # or for ONLY the media repo, do this: # # yum --disablerepo=\* --enablerepo=c7-media [command] [c7-media] name=CentOS-$releasever - Media baseurl=file:///home/yum/yum-iso/ gpgcheck=0 enabled=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7 |
3.1.检测安装软件是否成功
|
1 2 3 4 5 6 7 8 |
yum clean all yum makecache yum -y install ntp yum install ed openssh-clients zip unzip perl bind-utils net-tools -y |
4.卸载挂载
|
1 2 |
umount /home/yum-iso |
