实现私有Yum仓库

架构图

yum

每个系统的最后的路径都不一样，所以要看清，尽量跟大厂路径对齐，起始最重要的就是Packages和repodata，你看阿里云的路径，我们只要走到有repedata的文件夹下，就说明走对了，不用往下走了

主机拓扑

主机名	ip	os
yum server	192.168.48.128	Rocker8.9
client1	192.168.48.11	Centos Stream 8
client2	192.168.48.10	Centos 7

前情提要：所有要进行上传yum源的机子都要挂载光盘，也可以选择网络备份

自动挂载光盘

#自动挂载
yum install autofs -y
systemctl enable --now autofs
sed -i '/^[[:space:]]*#.*misc.*\/etc\/auto.misc/ s/^#//' /etc/auto.master
systemctl restart autofs
ls /misc/cd

部署yum server

操作节点：【yum server】

Rocky8

yum install -y httpd
systemctl disable --now firewalld.service
systemctl enable --now httpd.service

#自己看前面的教程实现rocky8的光盘自动挂载

#将本地光盘中的内容CP到web目录中，给客户端使用
mkdir -p /var/www/html/rockylinux/8/{BaseOS,AppStream}
cp -r /misc/cd/BaseOS/* /var/www/html/rockylinux/8/BaseOS
cp -r /mnt/BaseOS/repodata /var/www/html/rockylinux/8/BaseOS/
cp -r /misc/cd/AppStream/* /var/www/html/rockylinux/8/AppStream
cp -r /mnt/AppStream/repodata /var/www/html/rockylinux/8/AppStream/
#这里可能有点慢，因为要拷贝的文件有点多

现在一些基本的文件都拷过去了访问网页就可以看见了

假设我还有个extras源想拷过去呢？前面那个是走本地，这个可以走网络，这时候就可以用到yum仓同步工具

#备份自己的源
mkdir -p repo.bak
mv /etc/yum.repos.d/* repo.bak/

#CentOS 8 dnf 工具集成 REPOID是那个repo里的[]里的名字
dnf reposync --repoid=REPOID --download-metadata -p /path 
dnf reposync --help #查看帮助
#CentOS 7 以前版本，reposync工具来自于yum-utils包
reposync --repoid=REPOID --download-metadata -p /path

#创建好对应的路径，由于AppStream和BaseOS已经手动拉过去了，但是路径不对，我们就手动移一下
cd /var/www/html/rockylinux/8
mkdir -p AppStream/x86_64/os/
mkdir -p BaseOS/x86_64/os/
mv AppStream/{Packages,repodata} AppStream/x86_64/os/
mv BaseOS/{Packages,repodata} BaseOS/x86_64/os/
#开始同步，这里最后-p 路径的就不用加extras
mkdir -p /var/www/html/rockylinux/8/
yum reposync --repoid=extras-external-rocky8 --download-metadata -p /var/www/html/rockylinux/8/
#但是这个时候他的名字是extras-external-rocky8，所以你要把他下面的内容移动到extras去，还要注意有没有x86_64/os/
mv /var/www/html/rockylinux/8/{extras-external-rocky8,extras}
mkdir -p extras/x86_64/os/
mv extras/{Packages,repodata} extras/x86_64/os/

这就是成果

测试自己是否能创建缓存成功

#用的是私有repo，记得把其他的repo移走
[root@localhost 8]# yum clean all && yum makecache

远程同步

操作节点：【Centos Strem 8】

从Centos Strem 8复制到yumserver，如果你没有centos stream 8的机子，那就直接选网络同步

#自己看前面的教程实现rocky8的光盘自动挂载
#将本地光盘中的内容CP到yum server 的web目录中
scp -r /misc/cd/BaseOS 192.168.48.128:/var/www/html/centos/8-stream/
scp -r /misc/cd/AppStream 192.168.48.128:/var/www/html/centos/8-stream/

如果他报这个错，你要确保你的extras下的那个路径有没有repodata这个文件夹，或者看看路径对不对
