RedHat Enterprise Linux6.4 使用CentOS yum源

 

查看系统信息：

[admin@server1 ~]$ uname -a

Linux server1 2.6.32-358.el6.x86_64 #1 SMP Tue Jan 29 11:47:41 EST 2013 x86_64 x86_64 x86_64 GNU/Linux

在使用redhat linux的yum来安装或者更新软件的时候会提示

1. [admin@server1 ~]$ sudo yum install gcc
2. Loaded plugins: product-id, refresh-packagekit, security, subscription-manager
3. This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
4. Setting up Install Process
5. No package gcc available.
6. Error: Nothing to do

[注]请以root身份操作

由于 redhat的yum在线更新是收费的，如果没有注册的话不能使用，如果要使用，需将redhat的yum卸载后，重启安装，再配置其他源
解决办法：
1、首先到http://mirrors.163.com/centos下载软件包

## x86 地址：http://mirrors.163.com/centos/6/os/i386/Packages/
## x86_64 地址：http://mirrors.163.com/centos/6/os/x86_64/Packages/
## 必要下载的软件包有（以64位系统为例）：
 python-iniparse-0.3.-2.1.el6.noarch.rpm
 yum-3.2.-.el6.centos.noarch.rpm
 yum-metadata-parser-1.1.-.el6.x86_64.rpm
 yum-plugin-fastestmirror-1.1.-.el6.noarch.rpm

下载命令：

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-40.el6.centos.noarch.rpm wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

[注] :版本不一定要最新的(http://mirrors.163.com/centos/6/os/x86_64/Packages/ 查找对应版本)

2、卸载RedHat自带的yum

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

注：1>   xargs是一条Unix和类Unix操作系统的常用命令。它的作用是将参数列表转换成小块分段传递给其他命令，以避免参数列表过长的问题

2>   --nodeps  强制卸载,不管依赖性
 
3、安装下载的centos的yum包：

rpm -ivh python-iniparse-0.3.-2.1.el6.noarch.rpm
rpm -ivh yum-metadata-parser-1.1.-.el6.x86_64.rpm
rpm -ivh yum-3.2.-.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.-.el6.noarch.rpm 

[注] :最后2个需要一起安装，否则会出现依赖性错误

4、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

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

5、编辑CentOS6-Base-163.repo文件，将其中的$releasever更改为centos的版本号

下面是修改好的：

# 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.
#
#

6、yum clean all 清除原有缓存

7、yum makecache  获取yum列表
出现下面提示，表示yum更改完成：
Metadata Cache Created

脚本：

#!/bin/bash
PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:~/bin
export PATH

# Check if user is root
if [ $(id -u) != "" ]; then
    echo "Error: You must be root to run this script"
    exit
fi

clear

# replace repos
## 将修改改好的CentOS6-Base-163.repo 拷贝到/etc/yum.repo.d/中
##然后执行下面命令
yum clean all
yum makecache
yum update

echo "=========================================================================="
echo "You have successfully replace RedhatEnterprise Yum to CentOS yum and repos"
