RedHat5.6、6.0使用CentOS yum源

如何修改Centos yum源

--------------------------------------
国内yum源： 163和搜狐的yum源。 

本文章介绍的yum源支持的版本是CentOS 5系列，理论上支持RHEL5系列。 
 伦理片 http://www.dotdy.com/

更新方法如下： 

先进入yum源配置目录

 cd /etc/yum.repos.d

 

备份系统自带的yum源

 mv CentOS-Base.repo CentOS-Base.repo.save

 

下载其他更快的yum源

 中科大的yum源：（现在打不开了 ）

 wget http://centos.ustc.edu.cn/CentOS-Base.repo
 

163的yum源：

 wget http://mirrors.163.com/.help/CentOS-Base-163.repo
修改CentOS-Base.repo  （不修改会报错），下载到本地把“$releasever”，替换成“5”

sohu的yum源

 wget http://mirrors.sohu.com/help/CentOS-Base-sohu.repo
更新玩yum源后，建议更新一下，使操作立即生效

 yum makecache 

RedHat5.6使用CentOS yum源更新的方法

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

由于RedHat的yum在线更新是收费的，我们的RedHat没有注册，不能在线更新下载rpm包。

需将RedHat的yum卸载后，重启安装Centos的yum,再配置其他yum源。

 

一、确认RedHat的版本

cat /etc/redhat-release

uname -m

二、删除redhat原有的yum源

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

三、下载CentOS的yum安装包（163源）  (可以在这里手工找rpm包：http://mirrors.163.com/centos/)

32位系统：

wget http://mirrors.163.com/centos/5/os/i386/CentOS/yum-metadata-parser-1.1.2-3.el5.centos.i386.rpm
wget http://mirrors.163.com/centos/5/os/i386/CentOS/yum-3.2.22-39.el5.centos.noarch.rpm
wget http://mirrors.163.com/centos/5/os/i386/CentOS/yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm
64位系统：

wget http://mirrors.163.com/centos/5/os/x86_64/CentOS/yum-metadata-parser-1.1.2-3.el5.centos.x86_64.rpm
wget http://mirrors.163.com/centos/5/os/x86_64/CentOS/yum-3.2.22-39.el5.centos.noarch.rpm
wget http://mirrors.163.com/centos/5/os/x86_64/CentOS/yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm
还依赖python-iniparse-0.2.3-4.el5.noarch.rpm，

但我的系统里已安装了，是系统默认Python2.4中自带的。

如果你的系统没有安装，请安装吧。

四、安装yum软件包

32位系统：

rpm -ivh yum-metadata-parser-1.1.2-3.el5.centos.i386.rpm

rpm -ivh yum-3.2.22-39.el5.centos.noarch.rpm  yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm 

注意：最后两个安装包要放在一起同时安装，否则会提示相互依赖，安装失败。

64位系统：

rpm -ivh yum-metadata-parser-1.1.2-3.el5.centos.x86_64.rpm

rpm -ivh yum-3.2.22-39.el5.centos.noarch.rpm  yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm 

注意：最后两个安装包要放在一起同时安装，否则会提示相互依赖，安装失败。

五、更改yum源  #我们使用网易的CentOS镜像源

cd /etc/yum.repos.d/

vi 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.

#

#

[base]

name=CentOS-5 - Base - 163.com

mirrorlist=http://mirrorlist.centos.org/?release=5&arch=$basearch&repo=os

baseurl=http://mirrors.163.com/centos/5/os/$basearch/

#additional packages that may be useful

[extras]

baseurl=http://mirrors.163.com/centos/5/extras/$basearch/

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5

#additional packages that extend functionality of existing packages

[centosplus]

name=CentOS-5 - Plus - 163.com

mirrorlist=http://mirrorlist.centos.org/?release=5&arch=$basearch&repo=centosplus

baseurl=http://mirrors.163.com/centos/5/centosplus/$basearch/

gpgcheck=1

enabled=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5

#contrib - packages by Centos Users

baseurl=http://mirrors.163.com/centos/5/contrib/$basearch/

gpgcheck=1

enabled=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5

六、清理

yum clean all

yum makecache  

如果报错：imary.sqlite.bz2 from base: [Errno 256] No more mirrors to try.

执行：yum makecache  

 

 

 

七、更新

cd /etc/pki/rpm-gpg

wget http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
yum update

很长时间的下载后，报错：

warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID e8562897

GPG key retrieval failed: [Errno 5] OSError: [Errno 2] No such file or directory: '/etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5'

这是因为：指定的文件/etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5在本地不存在导致的。 

解决：

去官网http://mirror.centos.org/centos/下载相应文件

cd /etc/pki/rpm-gpg

wget http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

RedHat6.0使用CentOS yum源更新的方法

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

由于RedHat的yum在线更新是收费的，我们的RedHat没有注册，不能在线更新下载rpm包。

需将RedHat的yum卸载后，重启安装Centos的yum,再配置其他yum源。

一、确认RedHat的版本

cat /etc/redhat-release

uname -m

二、删除redhat原有的yum源

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

三、下载CentOS的yum安装包（163源）

32位系统 ：

wget http://mirrors.163.com/centos/6/os/i386/Packages/yum-3.2.29-22.el6.centos.noarch.rpm
wget http://mirrors.163.com/centos/6/os/i386/Packages/yum-metadata-parser-1.1.2-16.el6.i686.rpm
wget http://mirrors.163.com/centos/6/os/i386/Packages/yum-plugin-fastestmirror-1.1.30-10.el6.noarch.rpm
wget http://mirrors.163.com/centos/6/os/i386/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
四、安装yum软件包

rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm

rpm -ivh yum-metadata-parser-1.1.2-16.el6.i686.rpm

rpm -ivh yum-3.2.29-22.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-10.el6.noarch.rpm

注意：最后两个安装包要放在一起同时安装，否则会提示相互依赖，安装失败。

五、更改yum源  #我们使用网易的CentOS镜像源

cd /etc/yum.repos.d/

vi 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.

#

#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=os

六、清理

yum clean all

yum makecache  

如果报错：imary.sqlite.bz2 from base: [Errno 256] No more mirrors to try.

执行：yum makecache  

至此，Redhat6可以使用CentOS的yum源在线安装软件了！
