CentOS 构建本地源YUM服务

想必大家对linux下的YUM服务并不陌生吧，之前有将linux下redhat构建YUM的步骤有写出来，今天主要写一下如何在centos下构建YUM，尽管centos是redhat的克隆版，但也有很多的不同之处；

此链接是讲解如何在redhat上构建YUM，http://www.linuxdiyf.com/bbs/viewthread.php?tid=204212&extra=page%3D2%26amp%3Borderby%3Ddateline

下面是CentOS下构建YUM的步骤

1.首先把镜像盘挂在上：mount /dev/cdrom /media/cdrom/

2.安装http的包，  rpm -ivh /media/cdrom/CentOS/httpd-2.2.3-43.el5.centos.i386.rpm

 3.安装YUM常用的RPM包（有的包是默认已经安装的，但也要查一下是否安装）

  rpm -ivh /media/cdrom/CentOS/yum-3.2.22-26.el5.centos.noarch.rpm

   rpm -ivh /media/cdrom/CentOS/yum-metadata-parser-1.1.2-3.el5.centos.i386.rpm

   rpm -ivh /media/cdrom/CentOS/yum-fastestmirror-1.1.16-14.el5.centos.1.noarch.rpm

   rpm -ivh /media/cdrom/CentOS/yum-updatesd-0.9-2.el5.noarch.rpm

 4.新建一个自定义的目录，用来放置你的RPM包，也是http访问的目录：/data/CentOS/i386/

将挂在的rpm包的集合复制一份到/data/CentOS/i386/下，（因为你不可能挂在你的镜像盘一辈子）

 /cp -rf /media/cdrom/CentOS/ /data/CentOS/i386/

5.将/media/cdrom下的repodata/ 拷贝到/data/CentOS/i386/CentOS下

 cp -rf /media/cdrom/repodata/ /data/CentOS/i386/CentOS/       （后面会用到的）

6.安装rpm -ivh /media/cdrom/CentOS/createrepo-0.4.11-3.el5.noarch.rpm  （此包是用来安装服务端设置软件仓库及信息文件）

 rpm -ivh /media/cdrom/CentOS/createrepo-0.4.11-3.el5.noarch.rpm

7.先把http服务启动，service httpd start ,如果这个服务不能搞定，其他的一切都是做无用功）

 netstat -anpt | grep 80

tcp        0      0 :::80                       :::*                        LISTEN      8389/httpd

 8.生成客户端所需的信息文件

createrepo  -g /media/cdrom/repodata/comps.xml /data/CentOS/i386/

9.将key文件（用于客户端与服务端的认证）拷入指定目录/data/CentOS/i386 下

cp /media/cdrom/RPM-GPG-KEY-CentOS-5 /data/CentOS/i386/

10.修改http服务的配置文件，如何你是默认安装的httpd，其配置文件路径为：

vi /etc/httpd/conf/httpd.conf

 修改一下两行即可：（显示的是更改后的）

DocumentRoot "/data/CentOS/"

<Directory "/data/CentOS/">

之后保存，退出。。重启httpd服务、、、service httpd restart

11.用你的IE浏览器浏览下，看能不能访问http://172.16.17.140/i386/CentOS/ 下面显示的是rpm包算是正却的

12.更改yum的配置文件，更改之前要做好备份

、cp CentOS-Base.repo CentOS-Base.repo.bak

 之后清空你的CentOS-Base.repo 文件

方法：> CentOS-Base.repo  即可

vi CentOS-Base.repo

 [base]

name=CentOS5.3-base

baseurl=http://172.16.17.140/i386/

enable=1

gpgcheck=1

gpgkey=http://172.16.17.140/i386/RPM-GPG-KEY-CentOS-5

这样即可了

下面就是测试了。。。

先执行下yum clean all

之后验证下

[root@centos yum.repos.d]# yum install gcc
