一. YUM源服务器搭建（httpd方式）

1. 检查机器信息

[root@yumserver ~]# hostname

4. 配置YUM源文件，将光盘内容COPY到对应目录

[root@yumserver ~]# cd /var/www/html/
[root@yumserver html]# ll
total 8
drwxrwxr-x.  7 root root 4096 Feb 14 09:48 Centos6.9
drwxrwxr-x. 10 root root  251 Feb 14 17:50 Centos7.3

drwxrwxr-x. 12 root root 4096 Feb 13 11:30 Redhat6.9

5. 对目录进行yum源库的建立

[root@yumserver ~]# createrepo /var/www/html/Centos6.9
Spawning worker 0 with 810 pkgs
Spawning worker 1 with 810 pkgs

6. 客户端yum配置文件

cat /etc/yum.repos.d/cdrom.repo
[cdrom]
name=cdrom
baseurl=http://10.129.169.18/Redhat6.9

总结：这次部署的YUM源服务器采用的是httpd方式，其实也可以通过ftp实现，这个有机会再完善吧。在部署过程中需要注意的如果操作系统没有安装httpd，createrpop两个软件包，可以先通过挂载cdrom方式，将其装好。最后再叨唠两句，好久没发文了，不对，是太久太久啦！这次回归，希望能给自己学习的道路上再添砖加瓦。Where there is a will, there is a way.
