配置Redhat Enterprise Linux 5.3使用CentOS的更新源

RHEL系列是使用最广的Linux服务器系统之一，但是对于未付费用户，却无法通过Redhat网络安装和更新软件，这不能不说是一个遗 憾。其实 我们完全可以通过RHEL的同胞兄弟CentOS的源来更新，步骤如下：

1、在 /etc/yum.repos.d/ 目录下新建一个文件 CentOS-Base.repo

#vi CentOS-Base.repo

 

2、在该文件中录入以下内容并保存（本例的源在撰写本文时是有效的）：

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

#released updates
[update]
name=CentOS-5 – Updates
#mirrorlist=http://mirrorlist./?release=4&arch=$basearch&repo=updates
baseurl=http://ftp./centos/5/updates/$basearch/
gpgcheck=1
gpgkey=http://mirror./centos/RPM-GPG-KEY-centos5

#packages used/produced in the build but not released
[addons]
name=CentOS-5 – Addons
#mirrorlist=http://mirrorlist./?release=4&arch=$basearch&repo=addons

baseurl=http://ftp./centos/5/addons/$basearch/
gpgcheck=1
gpgkey=http://mirror./centos/RPM-GPG-KEY-centos5

#additional packages that may be useful
[extras]
name=CentOS-5 – Extras
#mirrorlist=http://mirrorlist./?release=4&arch=$basearch&repo=extras

baseurl=http://ftp./centos/5/extras/$basearch/
gpgcheck=1
gpgkey=http://mirror./centos/RPM-GPG-KEY-centos5

#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-5 – Plus
#mirrorlist=http://mirrorlist./?release=4&arch=$basearch&repo=centosplus
baseurl=http://ftp./centos/5/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://mirror./centos/RPM-GPG-KEY-centos5

#contrib – packages by Centos Users
[contrib]
name=CentOS-5 – Contrib
#mirrorlist=http://mirrorlist./?release=4&arch=$basearch&repo=contrib
baseurl=http://ftp./centos/5/contrib/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://mirror./centos/RPM-GPG-KEY-centos5

 3、执行更新：

# yum update

 

======================================

另外，如果服务器需要通过代理上网，则需要设置一下代理服务器才能进行联网更新：

在 /etc/yum.conf文件加入下面一行内容，指定一下代理服务器参数：

 

#Set http proxy
proxy=http://192.168.1.100:8000
