RedHat yum 源配置

RHEL5 配置YUM源

1.删除RedHat原有的yum：

rpm -aq | grep yum | xargs rpm -e --nodeps

2.下载yum安装组件：（随本机安装版本而定
[http://mirrors.163.com/centos/6/os/x86_64/Packages/]

wget http://mirrors.163.com/centos/6.3/os/x86_64/Packages/yum-3.2.29-30.el6.centos.noarch.rpm  
wget http://mirrors.163.com/centos/6.3/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm 
wget http://mirrors.163.com/centos/6.3/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm 

wget http://mirrors.163.com/centos/6.3/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm 

3.进行安装yum

1. rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm  
2. rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm  
3. rpm -ivh yum-3.2.29-30.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm 
   

最后两个包一块安装，会相互依赖

4.在/etc/yum.repos.d/文件夹下新建一个名为rhel-debuginfo.repo的文件，

 cd /etc/yum.repos.d/
cp rhel-debuginfo.repo rhel-debuginfo.repo.bak
先删除rhel-debuginfo.repo文件中所有内容，然后添加以下内容：

[base]
name=CentOS-5 - Base
 #mirrorlist=http://mirrorlist.centos.org/?release=$releasever5&arch=$basearch&repo=os
 #baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/baseurl=http://ftp.sjtu.edu.cn/centos/5/os/$basearch/gpgcheck=1gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5

gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-centos5
 #packages used/produced in the build but not released

#additional packages that may be useful

# vi dag.repo
[dag]
name=Dag RPM Repository for RHEL5
baseurl=http://ftp.riken.jp/Linux/dag/redhat/el5/en/$basearch/dag/
enabled=1
gpgcheck=1
gpgkey=http://ftp.riken.jp/Linux/dag/packages/RPM-GPG-KEY.dag.txt

然后导入key
 rpm --importhttp://ftp.sjtu.edu.cn/centos/6/os/x86_64/RPM-GPG-KEY-CentOS-6
[http://ftp.sjtu.edu.cn/centos/6/os/x86_64/]

5.
 cd /etc
cp yum.conf  yum.conf.bak
先删除 yum.conf 文件中所有内容，然后添加以下内容：

[main]
cachedir=/var/cache/yum
keepcache=1
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=redhat-release

#additional packages that may be useful

#additional packages that extend functionality of existingpackages
[centosplus]

gpgcheck=1

6.这时候也可以测试一下yum命令是否可用，也可以使用yum update进行升级。

yum clean all

yum install vim

  yum update
