Redhat 6.2 Linux修改yum源免费使用CentOS源

 

在没有光盘的情况，需要安装软件包，就要用到公网的yum源来安装了。

 

      Redhat linux 默认是安装了yum软件的，但是由于激活认证的原因让redhat无法直接进行yum安装一些软件，如果我们需要在redhat下直接yum安装软件，我们只用把yum的源修改成centos的就好了，然后把源里面的变量全部修改成实际的值，这样就能使用yum直接安装我们需要的软件了。

 

使用说明

1、到http://mirrors.163.com的 centos帮助文档 中下载CentOS6-Base-163.repo文件，存放到/etc/yum.repo.d中

cd /etc/yum.repo.d

Centos 5     wget  http://mirrors.163.com/.help/CentOS5-Base-163.repo

Centos 6     wget  http://mirrors.163.com/.help/CentOS6-Base-163.repo

 

其中有两个变量

$releasever $basearch

$releasever=6Server 这个在163是取不到的，（坑爹啊！）修改为6。

$basearch=x86_64 不用修改

 

CentOS6-Base-163.repo

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.

---------------------------------------------

 

可以配置yum本地源

1，挂载光盘

mount /dev/cdrom /mnt/media

2,新建本地yun源的配置文件

vi /etc/yum.repos.d/local.repo

加入以下信息：

[Local]

name=Local

baseurl=file:///mnt/media

enable=1

gpgcheck=0
