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 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/"
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 Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile base | 1.1 kB 00:00 base/primary | 912 kB 00:00 base 2599/2599 Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package gcc.i386 0:4.1.2-48.el5 set to be updated --> Processing Dependency: libgomp >= 4.1.2-48.el5 for package: gcc --> Processing Dependency: glibc-devel >= 2.2.90-12 for package: gcc --> Running transaction check ---> Package glibc-devel.i386 0:2.5-49 set to be updated --> Processing Dependency: glibc-headers = 2.5-49 for package: glibc-devel --> Processing Dependency: glibc-headers for package: glibc-devel ---> Package libgomp.i386 0:4.4.0-6.el5 set to be updated --> Running transaction check ---> Package glibc-headers.i386 0:2.5-49 set to be updated --> Processing Dependency: kernel-headers >= 2.2.1 for package: glibc-headers --> Processing Dependency: kernel-headers for package: glibc-headers --> Running transaction check ---> Package kernel-headers.i386 0:2.6.18-194.el5 set to be updated --> Finished Dependency Resolution Dependencies Resolved =============================================================================================================== Package Arch Version Repository Size =============================================================================================================== Installing: gcc i386 4.1.2-48.el5 base 5.2 M Installing for dependencies: glibc-devel i386 2.5-49 base 2.0 M glibc-headers i386 2.5-49 base 601 k kernel-headers i386 2.6.18-194.el5 base 1.0 M libgomp i386 4.4.0-6.el5 base 70 k Transaction Summary =============================================================================================================== Install 5 Package(s) Upgrade 0 Package(s) Total download size: 8.9 M Is this ok [y/N]: y Downloading Packages: (1/5): libgomp-4.4.0-6.el5.i386.rpm | 70 kB 00:00 (2/5): glibc-headers-2.5-49.i386.rpm | 601 kB 00:00 (3/5): kernel-headers-2.6.18-194.el5.i386.rpm | 1.0 MB 00:00 (4/5): glibc-devel-2.5-49.i386.rpm | 2.0 MB 00:00 (5/5): gcc-4.1.2-48.el5.i386.rpm | 5.2 MB 00:00 --------------------------------------------------------------------------------------------------------------- Total 14 MB/s | 8.9 MB 00:00 warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID e8562897 base/gpgkey | 1.5 kB 00:00 Importing GPG key 0xE8562897 "CentOS-5 Key (CentOS 5 Official Signing Key) " from http://172.16.17.140/i386/RPM-GPG-KEY-CentOS-5 Is this ok [y/N]: y Running rpm_check_debug Running Transaction Test Finished Transaction Test Transaction Test Succeeded Running Transaction Installing : libgomp 1/5 Installing : kernel-headers 2/5 Installing : glibc-headers 3/5 Installing : glibc-devel 4/5 Installing : gcc 5/5 Installed: gcc.i386 0:4.1.2-48.el5 Dependency Installed: glibc-devel.i386 0:2.5-49 glibc-headers.i386 0:2.5-49 kernel-headers.i386 0:2.6.18-194.el5 libgomp.i386 0:4.4.0-6.el5 Complete!
