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,就要用到共网的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
Centos 5 wget http://mirrors.163.com/.help/CentOS5-Base-163.repo
Centos 6 wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
操作如下:
2、首先备份/etc/yum.repos.d/CentOS-Base.repo
3、编辑CentOS6-Base-163.repo文件,将其中的$releasever更改为centos的版本号,如果是RedHat 6.2 X86_64为例“baseurl=http://mirrors.163.com/centos/6.2/os/x86_64/”,本文档是以RedHat 6.2 32位为例所写!
