centos6.4搭建基于ftp的yum源让本地局域网服务器使用

1. 挂载centos6.4 DVD镜像
[root@centos64 ~]# mount /dev/cdrom /mnt

2. 安装vsftp软件,启动vsftpd服务,拷贝centos6.4 DVD内容到ftp的匿名用户某一目录。
[root@centos64 Packages]# rpm -ivh vsftpd-2.2.2-11.el6_3.1.x86_64.rpm
Preparing...                ########################################### [100%]
   1:vsftpd                 ########################################### [100%]
[root@centos64 Packages]#
[root@centos64 Packages]#
[root@centos64 Packages]# chkconfig vsftpd on
[root@centos64 Packages]#
[root@centos64 Packages]# cd /var/ftp/
[root@centos64 ftp]#
[root@centos64 ftp]#
[root@centos64 ftp]# ls
pub
[root@centos64 ftp]# rm -rf pub/
[root@centos64 ftp]# service vsftpd start
Starting vsftpd for vsftpd:                                [ OK ]
[root@centos64 ftp]# mkdir centos6.4-x86_64 centos5.9-x86_64 ##顺便练centos5.9的软件源也一起搭建起来
[root@centos64 ftp]# cd centos6.4-x86_64/
[root@centos64 centos6.4-x86_64]#
[root@centos64 centos6.4-x86_64]# cp -rp /mnt/* .

3. 创建依赖关系数据库
[root@centos64 ~]# cd /mnt/Packages/
[root@centos64 Packages]# rpm -ivh createrepo-0.9.9-17.el6.noarch.rpm
[root@centos64 Packages]# createrepo -g /var/ftp/centos6.4-x86_64/repodata/repomd.xml /var/ftp/centos6.4-x86_64/
Spawning worker 0 with 3955 pkgs
Workers Finished

[root@centos64 Packages]#

4. yum的客户端需要修改yum配置文件：
移走/etc/yum.repos.d/所有的.repo文件。
[root@centos64 ~]# cd /etc/yum.repos.d/
[root@centos64 yum.repos.d]# ls
CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo epel.repo epel-testing.repo
[root@centos64 yum.repos.d]# mkdir bak
[root@centos64 yum.repos.d]# mv CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo bak/
[root@centos64 yum.repos.d]# ls
bak epel.repo epel-testing.repo
[root@centos64 yum.repos.d]# vi centos6.4.repo
[root@centos64 yum.repos.d]#
[root@centos64 yum.repos.d]# more centos6.4.repo
[centos6.4]
name=centos6.4
baseurl=ftp://192.168.1.64/centos6.4-x86_64/
enabled=1
[root@centos64 yum.repos.d]#
[root@centos64 yum.repos.d]# yum list all
如果出现如下带有centos6.4的标记，说明成功
......
yum-plugin-aliases.noarch                                      1.1.30-14.el6                             centos6.4
yum-plugin-changelog.noarch                                    1.1.30-14.el6                             centos6.4
yum-plugin-downloadonly.noarch                                 1.1.30-14.el6                             centos6.4
yum-plugin-security.noarch                                     1.1.30-14.el6                             centos6.4
......

5. 同样的方法搭建centos5.9的yum源
说明：这里有个大大的陷阱，当你把centos5.9的DVD源复制到centos6的系统，然后用centos6的createrepo命令创建依赖数据库的时候，发现虽然没有报错，但是这样的源，在centos5客户端yum 安装的时候，报效验错误的提示。如下：
[root@centos59 yum.repos.d]# yum list all
Loaded plugins: fastestmirror, security
Loading mirror speeds from cached hostfile
centos5.9/primary_db                                                                                                                            | 2.0 MB     00:00
ftp://192.168.1.64/centos5.9-x86_64/repodata/d219ce6ac81a48dc4b3295d72b6e26ea0cecd3b03f9a1c1655132d53508ad965-primary.sqlite.bz2: [Errno -3] Error performing checksum
Trying other mirror.
Error: failure: repodata/d219ce6ac81a48dc4b3295d72b6e26ea0cecd3b03f9a1c1655132d53508ad965-primary.sqlite.bz2 from centos5.9: [Errno 256] No more mirrors to try.
[root@centos59 yum.repos.d]#
原因是：centos6中的createrepo 命令，是用的是光碟 Rackages/路径，而centos5中用的是 CentOS/路径，所以问题就出来了。原来校验的时候，centos5的软件包只能用centos5中的createrepos命令。
解决方法是：把centos6中的/var/ftp/ 用nfs挂载到 centos5的 /var/ftp/ 同样路径下，用centos5的createrepo命令生成依赖数据库。
在centos6下面，装上nfs并挂载，如下：
[root@centos64 centos5.9-x86_64]# more /etc/exports
/var/ftp *(rw,sync)
[root@centos64 centos5.9-x86_64]#
centos5.9上面挂载命令如下： mount 192.168.1.65:/var/ftp /var/ftp

下面是在centos5中执行的createrepo命令：

[root@centos59 CentOS]# createrepo -g /var/ftp/centos5.9-x86_64/repodata/repomd.xml /var/ftp/centos5.9-x86_64/
3579/3579 - CentOS/patch-2.5.4-31.el5.x86_64.rpm x86_64.rpm
Saving Primary metadata
Saving file lists metadata
Saving other metadata
[root@centos59 CentOS]#
执行上面的命令后，还是发现错误依旧
[root@centos59 yum.repos.d]# yum list all
Loaded plugins: fastestmirror, security
Loading mirror speeds from cached hostfile
centos5.9/primary_db | 2.0 MB 00:00
ftp://192.168.1.64/centos5.9-x86_64/repodata/d219ce6ac81a48dc4b3295d72b6e26ea0cecd3b03f9a1c1655132d53508ad965-primary.sqlite.bz2: [Errno -3] Error performing checksum
Trying other mirror.
Error: failure: repodata/d219ce6ac81a48dc4b3295d72b6e26ea0cecd3b03f9a1c1655132d53508ad965-primary.sqlite.bz2 from centos5.9: [Errno 256] No more mirrors to try.
[root@centos59 yum.repos.d]#
然后直接在centos6中清空掉 centos5.9-x86_64/repodata/ 中的垃圾数据，对比centos5.9 DVD源光盘镜像中的 repodata/ 目录，清空掉以前 centos6 的createrepo命令生成的垃圾文件，并且在centos5 中重命名一下centos5.9.repo 就好了。因为可能在centos5.9中有缓存的缘故。

===============以后碰到了如下问题：

以上方法只是解决了yum -y install XXXXX的安装问题，但是对于 yum groupinstall 安装的时候，就会报错，如下：

[root@BG-DB:/etc/yum.repos.d]$yum grouplist
Setting up Group Process
centos5.9/group | 1.1 kB 00:00
ftp://192.168.1.202/repodata/repomd.xml: [Errno -1] Metadata file does not match checksum
Trying other mirror.
Failed to add groups file for repository: centos5.9 - None
Error: No group data available for configured repositories
[root@BG-DB:/etc/yum.repos.d]$

原来没有在yum端创建组数据库，需要在yum源中

【centos5.X】需要如下方法执行：
[root@server202:/var/ftp/centos5.9-x86_64]$createrepo -g repodata/comps.xml . ##注意，这里和上面的不同，这个是组的数据库配置。
3579/3579 - CentOS/xorg-x11-drv-cirrus-1.1.0-2.fc6.x86_64.rpm pm6_64.rpm
Saving Primary metadata
Saving file lists metadata
Saving other metadata
[root@server202:/var/ftp/centos5.9-x86_64]$

【centos6.X】需要如下方法执行：

[root@centos65dvd centos6.5-x86_64]# createrepo -g repodata/b4e0b9342ef85d3059ff095fa7f140f654c2cb492837de689a58c581207d9632-c6-x86_64-comps.xml . ## centos6.X这里面的组文件和centos5.X 不一样
Spawning worker 0 with 3995 pkgs

--------------------------------------------------------------------------------------
做完上面的后，yum客户端用如下三条命令后，然后就可以“列出组软件包”了
yum clean all
yum makecache
yum list
如下：
[root@BG-DB:/etc/yum.repos.d]$more centos5.9.repo
[centos5.9]
name=centos5.9
baseurl=ftp://192.168.1.202/
enabled=1
