利用CentOS镜像文件制作yum 软件仓库
CentOS安装文件包含两个ISO文件，如6.5：
CentOS-6.5-x86_64-bin-DVD1.iso
CentOS-6.5-x86_64-bin-DVD2.iso
在安装系统系统时，只需要用到DVD1就可以了，DVD2中则包含了其他一些软件包。可以将两个ISO文件挂载到系统，并制作yum的本地仓库
制作软件仓库
-
挂载镜像文件
mkdir /mnt/cdrom1 mkdir /mnt/cdrom2 mount -o loop /opt/CentOS-6.5-x86_64-bin-DVD1.iso /mnt/cdrom1/ mount -o loop /opt/CentOS-6.5-x86_64-bin-DVD2.iso /mnt/cdrom2/如果是虚拟机，并且已经将镜像文件加载到DVD中，则使用以下命令挂载DVD
mount /dev/cdrom /mnt/cdrom1/ mount /dev/cdrom1 /mnt/cdrom2/ -
增加软件仓库配置文件，在/etc/yum.repos.d/目录下新建centos_isos.repo文件，并输入以下信息，然后就完成了
[centos_isos] name=CentOS-$releasever - isos baseurl=file:///mnt/cdrom1 file:///mnt/cdrom2 enabled=1 gpgcheck=0 gpgkey=以下为完整操作日志

将软件仓库配置为HTTP访问
当内网中有多台机器时，可以将上面的软件仓库发布为http方式供内网中其他服务器使用。
-
首先需要安装httpd服务。
httpd服务会自动将/var/www/html/目录下的文件发布为网络访问
yum install httpd
- 启动httpd服务，并设置开机启动
service httpd start
chkconfig httpd on
- 将iso挂载到指定目录下，通过httpd服务自动发布到网络
mkdir /var/www/html/cdrom1
mkdir /var/www/html/cdrom2
mount -o loop /opt/CentOS-6.5-x86_64-bin-DVD1.iso /var/www/html/cdrom1/
mount -o loop /opt/CentOS-6.5-x86_64-bin-DVD2.iso /var/www/html/cdrom2/
建议将以上两个文件设置为开机自动挂载，可通过在/etc/rc.local文件中增加以下内容开机自动挂载
mount -o loop /opt/CentOS-6.5-x86_64-bin-DVD1.iso /var/www/html/cdrom1/ mount -o loop /opt/CentOS-6.5-x86_64-bin-DVD2.iso /var/www/html/cdrom2/
- 配置软件仓库文件，修改前面建立的/etc/yum.repos.d/centos_isos.repo配置文件为HTTP访问方式
[centos_isos]
name=CentOS-$releasever - isos
baseurl=http://10.37.129.3/cdrom1/
http://10.37.129.3/cdrom2/
enabled=1
gpgcheck=0
gpgkey=
ok，至此配置完成，其他机器如果需要使用此软件仓库，只需要在/etc/yum.repos.d/目录下新建一个.repo结尾的文件，并且输入以上内容就可以了
