rhel源更换为centos源

禁用 RHEL 的每个仓库配置

修改目录 /etc/yum.repos.d 下每个文件，将 enable=1 改为 enable=0，或者也可以将这个目录清空

建立 CentOS 的配置 /etc/yum.repos.d/centos.repo ，内容为：

[CentOS5 base]
name=CentOS-5-Base
mirrorlist=http://mirrorlist.centos.org/?release=5&arch=$basearch&repo=os
gpgcheck=1
enabled=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
[CentOS5 updates]
name=CentOS-5-Updates
mirrorlist=http://mirrorlist.centos.org/?release=5&arch=$basearch&repo=updates
gpgcheck=1
enabled=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
[CentOS5plus]
name=CentOS-5-Plus
mirrorlist=http://mirrorlist.centos.org/?release=5&arch=$basearch&repo=centosplus
gpgcheck=1
enabled=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

这些仓库需要 GPG 验证，还需要把公钥复制下来。或者也可以将 centos.repo 中 gpgcheck=1 改为 gpgcheck=0 来避免验证：

rpm --import http://isoredirect.centos.org/centos/5/os/i386/RPM-GPG-KEY-CentOS-5

测试是否可用

[plain] view plaincopyprint?

# yum list available
Loaded plugins: product-id, refresh-packagekit, security, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
Bad id for repo: CentOS5 base, byte = 7
Bad id for repo: CentOS5 updates, byte = 7

上面的仓库地址是在这里找到的，因为仓库 ID 带了空格造成错误 Bad id for repo: CentOS5 base, byte = 7，去掉空格就可以了

Bad id 说的就是 repo 文件中方括号中的仓库 ID， byte = 7 为引起错误的地方

对于 “This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register” 问题

可在使用 yum 时禁用相应插件，如：

[plain] view plaincopyprint?

yum --disableplugin=subscription-manager list available

或将 /etc/yumconf 中 plugins=1 改为 plugins=0 来禁用所有插件

也可以禁用指定插件，在 /etc/yum/pluginconf.d 下找到插件对应的文件，如要禁用 subscription-manager 插件，修改 /etc/yum/pluginconf.d/subscription-manager.conf 文件

将 enabled=1 改为 enabled=0 即可

如果要得到更好的支持，可以把 CentOS 的 Release Node : centos-release 和 centos-release-notes 安装上

wget http://dl.fedoraproject.org/pub/epel/beta/7/x86_64/epel-release-7-1.noarch.rpm

yum install epel-release-7-1.noarch.rpm

或者用 rpm -ivh epel-release-7-1.noarch.rpm 安装

查看是否安装成功：

yum repolist

二、redhat配置centos源

vi /etc/yum.repos.d/CentOS-Base.repo

[base]

name=CentOS-5-Base

#mirrorlist=http://mirrorlist.centos.org/?release=$releasever5&arch=$basearch&repo=os

#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/

baseurl=http://ftp.sjtu.edu.cn/centos/7/os/$basearch/

gpgcheck=0

gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-7

#released updates

[updates]

name=CentOS-$releasever – Updates

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

baseurl=http://ftp.sjtu.edu.cn/centos/7/updates/$basearch/

gpgcheck=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

[extras]

name=CentOS-$releasever – Extras

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

baseurl=http://ftp.sjtu.edu.cn/centos/7/extras/$basearch/

gpgcheck=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

b[centosplus]

name=CentOS-$releasever – Plus

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

baseurl=http://ftp.sjtu.edu.cn/centos/7/centosplus/$basearch/

gpgcheck=0

enabled=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

rpm --import http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-7

rpm -qa gpg-pubkey

1 删除rhel自带的yum包：

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

2 安装yum：

[china~/yum_64#]rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm
warning:python-iniparse-0.3.1-2.1.el6.noarch.rpm: Header V3 RSA/SHA256 Signature, keyID c105b9de: NOKEY

3 添加网易163的yum源

获取文件：CentOS6-Base-163.repo

wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
cp CentOS-Base-163.repo rhel-source.repo
sed -i 's/\$releasever/6/g' rhel-source.repo

4 清空 yum 缓存

yum clean all

5 将服务器上的软件包信息缓存到本地

提高yum的更新效率

yum makecache
