redhat 的 yum 配置

yum分为服务器端和客户端
本例子为ftp服务器

yum安装软件只要提供想要安装的软件名，即可安装软件，排斥了rpm安装时的各种依赖关系（依赖起来可是很纠结了=。=）。

1、服务器端要安装createrepo-0.4.11-3.el5.noarch.rpm和yum-3.2.22-26.el5.noarch.rpm

[root@gg pub]# rpm -ivh createrepo-0.4.11-3.el5.noarch.rpm
[root@gg pub]# rpm -ivh yum-3.2.22-26.el5.noarch.rpm

2、挂载ISO光盘和复制所以的rpm包到/var/ftp/pub
[root@gg pub]# mount /dev/cdrom /media
[root@gg pub]# mkdir /var/ftp/pub/rpm
[root@gg pub]# cp -va /media/Server/* /var/ftp/pub/rpm/

3、重建索引
[root@gg pub]# createrepo -v /var/ftp/pub/rpm

4、yum配置文件路径 /etc/yum.repos.d/rhel-debuginfo.repo
新建出的yum配置文件必须以repo为后缀，并把原来的配置文件改名

[root@gg yum.repos.d]# cd
[root@gg ~]# cd /etc/yum.repos.d/
[root@gg yum.repos.d]# cp rhel-debuginfo.repo yum.repo
[root@gg yum.repos.d]# mv rhel-debuginfo.repo11 rhel-debuginfo.repo
[root@gg yum.repos.d]# vi yum.repo

我的yum.repo配置文件的内容

[rhel-debuginfo]
name=MyYum #名字
baseurl=ftp://192.168.0.99/pub/rpm #yum源的路径IP是我本机IP
enabled=1 #1为开启上面yum源
gpgcheck=0 #0为关闭GPG签名（用来验证要安装的包是不是REDHAT官方的）
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
#密钥位置,因为上面已经关闭了GPG签名验证所以没用.可以删除

5、关闭yum自动更新（开启的话很容易出错，或匹配不上）
[root@gg ~]# /etc/init.d/yum-updatesd stop

6、开启ftp服务
[root@gg ~]# service vsftpd start

7、开始用yum安装软件

[root@gg yum.repos.d]# yum -y install zsh*

补充：
yum常用命令
yum clean all
yum list
yum -y install 包名
yum remove 包名

ok！yum的配置就到这里，我这只是很简单的步骤，能让yum运行起来。

具体的配置信息就找度娘去吧....
