如果使用HTTP做YUM源,具体设置如下：

1 安装httpd安装包 #yum -y install httpd

2 挂载ISO，创建本地更新源

#mount -t iso9660 -o loop rh63.iso /mnt/cdrom

#cd /var/www/html/

#mkdir yum

# mount --bind /mnt/cdrom  yum

[root@localhost html]# vi /etc/yum.repos.d/yum.repo

[root@localhost html]# cat /etc/yum.repos.d/yum.repo

[RHEL]

name=rhel6.3

baseurl=http://192.168.1.130/yum/

gpgcheck=0

enabled=1

3 service httpd start    #启动httpd守护进程，否则在其他机器上会提示找不到相关源

  chkconfig httpd on     #设置系统服务

4 测试一下

[root@localhost yum.repos.d]# yum clean all

[root@localhost yum.repos.d]# yum makecache

5 报错说无法连接到YUM源

Loaded plugins: product-id, refresh-packagekit, security, subscription-manager

This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

http://192.168.161.1/rh63/repodata/repomd.xml: [Errno 14] PYCURL ERROR 7 - "couldn't connect to host"

Trying other mirror.

Error: Cannot retrieve repository metadata (repomd.xml) for repository: rhel-source. Please verify its path and try again

首先确认HTTPD服务启动了没有

service httpd status

并且检查有无防火墙限制，或者关闭防火墙

service iptables stop

其二如果还报无法连接错误

则删除一个认证文件

rm -rf /root/.ssh/known_hosts

再次如果还报验证有错误，则修改/etc/yum.conf文件

把其中的gpgcheck=1改为gpgcheck=0

6 再试试

[root@localhost yum.repos.d]# rpm -qa|grep telnet

[root@localhost yum.repos.d]# yum -y install telnet*

Installed:

telnet.i686 1:0.17-47.el6      telnet-server.i686 1:0.17-47.el6

Dependency Installed:

xinetd.i686 2:2.3.14-34.el6

Complete!

好了，YUM没问题了。
