yum命令可以快速的安装、卸载和升级软件，他的出现的最大好处是解决了软件在安装时的相关性问题。

在使用yum命令前，先要对这个命令创建一个软件库。

要创建软件库的话，就会使用到另一个命令，即createrepo

这个命令就是用来给yum创建软件库的。

由于createrepo这个命令在默认的安装里面没有安装，所以先得用rpm命令把它安装上

[root@localhost ~]# rpm -ivh /mnt/Server/createrepo-0.4.4-2.fc6.noarch.rpm
warning: /mnt/Server/createrepo-0.4.4-2.fc6.noarch.rpm: Header V3 DSA signature: NOKEY, key ID 37017186
Preparing...                ########################################### [100%]
   1:createrepo             ########################################### [100%]

准备工作都做完了，现在就要做个试验了。
我要把系统盘中的所有rpm包创建成一个软件库，之后用yum来安装dhcp的相关软件。

[root@localhost ~]# mkdir packages   创建一个文件夹（当然这个名字是自己随便起的）
[root@localhost ~]# cd packages/
[root@localhost packages]# cp /mnt/Server/rpm* .      把所有rpm包都拷到当前目录下
[root@localhost packages]# createrepo /root/packages/ 给yum创建软件库
2113/2113 - dbus-1.0.0-6.el5.i386.rpm
Saving Primary metadata
Saving file lists metadata
Saving other metadata
[root@localhost packages]# ls -l repodata/     可以看到，在创建完库后，系统会自动在该目录的
total 196                                      的子目录中建立一个文件名为repodata的文件
-rw-r--r-- 1 root root 33986 Jan 24 03:16 filelists.xml.gz 里面有这四个文件
-rw-r--r-- 1 root root 118095 Jan 24 03:16 other.xml.gz
-rw-r--r-- 1 root root 19896 Jan 24 03:16 primary.xml.gz
-rw-r--r-- 1 root root    951 Jan 24 03:16 repomd.xml

修改如下：
[root@server1 Server]# createrepo -g /var/RHEL51/mnt/Server/repodata/comps-rhel5-server-core.xml /var/RHEL51/mnt/Server/
2159/2159 - redhat-logos-4.9.16-1.noarch.rpm

Saving file lists metadata
Saving other metadata
Could not remove old metadata dir: .olddata
Error was [Errno 39] Directory not empty: '/var/RHEL51/mnt/Server/.olddata'
Please clean up this directory manually.

(这个是做Cluster的配置)
[root@server1 mnt]# createrepo -g /var/RHEL51/mnt/Cluster/repodata/comps-rhel5-cluster.xml /var/RHEL51/mnt/Cluster
32/32 - Cluster_Administration-zh-CN-5.1.0-7.noarch.rpm

Saving file lists metadata
Saving other metadata
Could not remove old metadata dir: .olddata
Error was [Errno 39] Directory not empty: '/var/RHEL51/mnt/Cluster/.olddata'
Please clean up this directory manually.

上面的是在做cluster时候才在里面添加的文件。

[root@localhost packages]# cd /etc/yum.        编辑一个文件，让yum识别到刚才新建立的软件库
yum.conf     yum.repos.d/
[root@localhost packages]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# ls
rhel-debuginfo.repo
[root@localhost yum.repos.d]# cp rhel-debuginfo.repo test.repo

[root@localhost yum.repos.d]# vi test.repo   在这里指明刚才建立的那个软件库的位置
[test]
name=test
baseurl=file:///root/packages
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
＃＃＃＃＃＃＃＃＃＃＃＃＃
可以根据自己的实际爱好，改变软件库的位置，也可以做成FTP，让其他的客户端可以直接使用。

也可以使用yum grouplist 和yum groupinstall等相关的参数。

补充：

在yum中，加上-y参数来省略掉中间的提示，yum update [packages] 升级该软件包，如果要是什么都不加的话，就是全部升级。
还有一些其他的相关参数我都还没有做。

下面的是我在本地做了一个yum源，然后局域网里面的其他电脑要使用我的yum源的一些操作（当然做一个FTP的yum源，也能实现局域网里面的电脑使用yum安装，就不需要下面的这些复杂操作了）

假如两台电脑：地址分别是192.168.1.11和192.168.1.12

我在192.168.1.11上面做了下面的一些操作，先是做了yum仓库，目录是在/var/Install，然后做了nfs,
里面的共享是这样的
/var/Install *(ro,sync)

在这台电脑上面，我可以使用yum grouplist等。

因为我做的是本地的，所以我要在192.168.1.12使用yum的一些资源，就要先把11上面的共享挂在到本地，
mount -t nfs 192.168.1.11:/var/Install /var/Install(这个是在本地创建的目录)
然后在把11上面的yum源的东西拷贝到12上面来，就可以使用yum安装了。
在192.168.1.11上面
scp /etc/yum.repose/test.repo(我自己随便起的) 192.168.1.12:/etc/yum.repose/
这样就把yum的一些东西拷贝到192.168.12上面了。然后使用yum install
yum grouplist yum list 等命令了。
