RHEL有时候使用自定义的YUM源是很方便的事情。
yum install createrepo
createrepo /your/repo/directory/
不过由于粗心，本人在使用时遇到很郁闷的坑，错误如下：
[root@localhost rpms]# yum install openssl
Loaded plugins: product-id, security, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

其它都正常就是下载不了文件。
经过很长时间的郁闷排查后，发现其实原来，创建repo的时候，RPM包一定要放在REPO目录下面的子目录中
下面的REPO是错误的
[root@localhost rpms]# ll
total 1548
-rw-r--r-- 1 root root 1578640 Nov 10 18:42 openssl-1.0.1e-16.el6_5.7.x86_64.rpm
drwxr-xr-x 2 root root 4096 Nov 11 12:21 repodata
[root@localhost rpms]# pwd
/var/www/html/rpms
正确的是
[root@nfsserver local-yum]# ll
total 8
drwxr-xr-x. 2 root root 4096 Nov 11 19:26 repodata
drwxr-xr-x. 2 root root 4096 Nov 11 19:25 x86_64
[root@nfsserver local-yum]#
X86_64中才是你要安装的RPM包。
==========
yum grouplist
一般情况下在执行yum grouplist时会报错Setting up Group Process Error: No group data available for configured repositories，这是因为源里缺少comps****.xpm文件造成的，这个文件可以在/home/unixer0 /Local_yum_source/Workstation/repodata（根据你的源位置）找到，不过名字并不是comps***而是一些数字字母组合，后面会跟着comps****.xpm例如6107d2dc7436b6e577ca7c20a552c687b224aa60b04bde96a862141bcdecbb36-comps-rhel6-Workstation.xml
复制这个文件到/home/unixer0/Local_yum_source目录下，并重新命名为comps-rhel6-Workstation.xml这样就可以了。重新执行上面的命令，好了，本地源就建立完成了。
5.可以打开add/remove software看下了，当然，要在它的设置部分system>software sources里勾选你刚建立的源，例如my_local_source.
