写本文的时候并没有实际的服务器供我使用，所以只能用虚拟机了，造成的不便请读者见谅，不过这篇文章完全可以用在实际工作中的YUM服务器，按本文配置YUM服务器的好处是你可以把一些软件放在服务器的Apache服务的根目录下，用网页打开可以直接下载。所以很方便。如果内网不会，或者不清楚，可以给我留言，我会给你详解的。谢谢大家的支持^ ^
实验环境
1)Oracle VM VirtualBox虚拟机
2)CentOS-6.5-x86_64-bin-DVD1.ISO光盘
3)Apache Web服务器
1.创建虚拟机YUM(前写篇文章介绍过怎么创建，这里不多做解释)；进入下一步
注:如果是实际公司需要，就直接在服务器上安装CentOS6.5系统然后配置。
2.配置网卡eth0，直至网络ping通为止；进入下一步
[root@YUM ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0DEVICE=eth0 网卡名字ONBOOT=yes 是否自动启动BOOTPROTO=dhcp 获取IP地址方式，这里是动态获取~~:wq 保存并退出[root@YUM ~]# ping www.baidu.comPING www.a.shifen.com (61.135.169.125) 56(84) bytes of data.64 bytes from 61.135.169.125: icmp_seq=1 ttl=54 time=4.19 ms64 bytes from 61.135.169.125: icmp_seq=2 ttl=54 time=3.79 ms64 bytes from 61.135.169.125: icmp_seq=3 ttl=54 time=6.93 ms^C--- www.a.shifen.com ping statistics ---3 packets transmitted, 3 received, 0% packet loss, time 2124msrtt min/avg/max/mdev = 3.797/4.975/6.931/1.394 ms
3.安装Apache Web服务；进入下一步
注:如果是内网则可以将Apache服务考入服务器中，用rpm -ivh安装；或者编译安装；或者先挂载光盘，再从挂载中的Packages文件夹中找到httpd.rpm安装包，进行安装。
[root@YUM ~]# yum -y install httpd*Complete! 安装完成
4.挂载CentOS-6.5-x86_64-bin-DVD1至/mnt文件夹下；进入下一步
[root@YUM ~]# mount /dev/cdrom2 /mnt[root@YUM ~]# cd /mnt/[root@YUM mnt]# lsCentOS_BuildTag isolinux RPM-GPG-KEY-CentOS-Debug-6EFI Packages RPM-GPG-KEY-CentOS-Security-6EULA RELEASE-NOTES-en-US.html RPM-GPG-KEY-CentOS-Testing-6GPL repodata TRANS.TBLp_w_picpaths RPM-GPG-KEY-CentOS-6[root@YUM mnt]#
5.在根目录下新建文件夹/data；进入下一步
[root@YUM mnt]# cd ../..[root@YUM /]# mkdir data[root@YUM /]# lsbin data etc lib lost+found mnt proc sbin srv tmp varboot dev home lib64 media opt root selinux sys usr
6.将挂载下的文件拷贝到/data/YUM中；进入下一步
[root@YUM /]# cp -rv /mnt/ /data/YUM[root@YUM /]# cd /data/YUM/[root@YUM YUM]# lsCentOS_BuildTag isolinux RPM-GPG-KEY-CentOS-Debug-6EFI Packages RPM-GPG-KEY-CentOS-Security-6EULA RELEASE-NOTES-en-US.html RPM-GPG-KEY-CentOS-Testing-6GPL repodata TRANS.TBLp_w_picpaths RPM-GPG-KEY-CentOS-6
7.修改Apache服务的配置文件；进入下一步
[root@YUM ~]# vi /etc/httpd/conf/httpd.conf# ServerName gives the name and port that the server uses to identify itself.# This can often be determined automatically, but we recommend you specify# it explicitly to prevent problems during startup.## If this is not set to valid DNS name for your host, server-generated# redirections will not work. See also the UseCanonicalName directive.## If your host doesn't have a registered DNS name, enter its IP address here.# You will have to access it by its address anyway, and this will make# redirections work in a sensible way.##ServerName www.example.com:80把ServerName www.example.com:80前的注释去掉即可# DocumentRoot: The directory out of which you will serve your# documents. By default, all requests are taken from this directory, but# symbolic links and aliases may be used to point to other locations.#DocumentRoot "/data"把/var/www/html改成/data即可# This should be changed to whatever you set DocumentRoot to.#把/var/www/html改成/data即可
8.打开防火墙(iptables)配置文件，加入80端口，进入下一步
[root@YUM ~]# vi /etc/sysconfig/iptables:INPUT ACCEPT [0:0]:FORWARD ACCEPT [0:0]:OUTPUT ACCEPT [0:0] 在这行下边-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPTCOMMIT 在这行上边从新起一行添加就行
9.关闭SELinux；进入下一步
[root@YUM ~]# vi /etc/selinux/configSELINUX=disabled将enforcing改成disabled
10.重启Apache服务和iptables防火墙，并且把Apache服务设置成开机启动；进入下一步
[root@YUM ~]# service httpd restartStopping httpd: [ OK ]Starting httpd: [ OK ][root@YUM ~]# chkconfig httpd on[root@YUM ~]# service iptables restartiptables: Setting chains to policy ACCEPT: filter [ OK ]iptables: Flushing firewall rules: [ OK ]iptables: Unloading modules: [ OK ]iptables: Applying firewall rules: [ OK ]
11.用IE浏览器打开服务器中的YUM源；创建完成。
出现这界面就可以了。。。
附:如果是公司用的YUM服务器，那是一定要禁掉root登陆的，在这里给大家写下来，希望对大家有帮助。。。。
禁掉root登录
[root@YUM ~]# vi /etc/passwdroot:x:0:0:root:/root:/sbin/nologin将/bin/bash改成/sbin/nologin
前提是你必须有个用户，否则的话就不能登陆了。
