                                        网络yum 的创建
网络访问yum可以基于ftp服务器，http服务器。这里以ftp服务器为例。
1. 光盘挂载
[root@localhost ~]# mkdir /mnt/cdrom
[root@localhost ~]# mount /dev/cdrom /mnt/cdrom/
mount: block device /dev/cdrom is write-protected, mounting read-only
2. 安装ftp
[root@localhost ~]# cd /mnt/cdrom/Server/
[root@localhostServer]# rpm -ivh vsftpd-2.0.5-16.el5.i386.rpm
warning: vsftpd-2.0.5-16.el5.i386.rpm: Header V3 DSA signature: NOKEY, key ID 37017186
Preparing...                ########################################### [100%]
   1:vsftpd                 ########################################### [100%]
3. 启动ftp服务器
[root@localhost Server]# service vsftpd start
Starting vsftpd for vsftpd:                                [ OK ]
[root@localhost Server]# ftp 127.0.0.1

ftp> dir
227 Entering Passive Mode (127,0,0,1,134,181)
150 Here comes the directory listing.
drwxr-xr-x    2 0        0            4096 May 13 2009 pub
226 Directory send OK.
4. 切换到/var/ftp/,随便创建一个目录，比如叫rhel,然后将/mnt/cdrom/的所有东西拷贝到rhel目录下
[root@localhost Server]# cd /var/ftp/
[root@localhost ftp]# ll
total 4
drwxr-xr-x 2 root root 4096 May 13 2009 pub
[root@localhost ftp]# mkdir rhel
[root@localhost ftp]# cd rhel/
[root@localhost rhel]# ll
total 0
[root@localhost rhel]# cp -a -r /mnt/cdrom/* ./
5. 查看rhel目录的大小
[root@localhost rhel]# cd ../
[root@localhost ftp]# du -sh rhel/
2.9G rhel/
6.安装createrepo包
    [root@localhost ~]# cd /mnt/cdrom/Server/
[root@localhost Server]# rpm -q cre*
package createrepo-0.4.11-3.el5.noarch.rpm is not installed
    [root@localhost Server]# rpm -ivh createrepo-0.4.11-3.el5.noarch.rpm
warning: createrepo-0.4.11-3.el5.noarch.rpm: Header V3 DSA signature: NOKEY, key ID 37017186
Preparing...                ########################################### [100%]
   1:createrepo             ########################################### [100%]
6. 如果你是第一次安装yum ，那么到这里就可以直接进行编辑
/etc/yum.repos.d文件，如果server目录下的包动过，那么就需要进行以下操作进行重组
   [root@localhost Server]# cd /var/ftp/rhel/
   [root@localhost rhel]# cd Server/
   [root@localhostServer]# createrepo -g repodata/comps-rhel5-server-core.xml ./
   [root@localhostVT]# createrepo -g repodata/comps-rhel5-vt.xml ./
   [root@localhostCluster]# createrepo -g repodata/comps-rhel5-cluster.xml ./
   [root@localhostClusterStorage]# createrepo -g repodata/comps-rhel5-cluster-st.xml ./
7. 切换到/etc/yum.repos.d
[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# cp rhel-debuginfo.repo server1.repo

8编辑server1.repo文件，假设你的ftp是ftp://192.168.101.249
