Redhat Linux通常由于没有注册,导致yum程序无法使用,需要将其替换为centos的yum程序。
1. 下载Yum的安装包,由于体系结构的不同和包的更新,因此目录和文件名的版本号可能需要调整以下。
#wget http://mirrors.163.com/centos/5/os/x86\_64/CentOS/yum-3.2.22-40.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
#wget http://mirrors.163.com/centos/5/os/x86\_64/CentOS/yum-metadata-parser-1.1.2-4.el5.x86\_64.rpm
2. 查出当前的yum程序,进行卸载
#rpm -qa|grep yum
# rpm -e yum-3.2.22-20.el5 --nodeps
# rpm -e yum-updatesd-0.9-2.el5 --nodeps
# rpm -e yum-security-1.1.16-13.el5 --nodeps
# rpm -e yum-metadata-parser-1.1.2-3.el5 --nodeps
# rpm -e yum-rhn-plugin-0.5.4-13.el5 --nodeps
3. 下载并导入KEY
# cd /etc/pki/rpm-gpg/
# wget http://mirrors.sohu.com/centos/RPM-GPG-KEY-CentOS-5
# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY*
4. 安装yum安装包
rpm -ivh yum-3.2.22-40.el5.centos.noarch.rpm \
yum-fastestmirror-1.1.16-21.el5.centos.noarch.rpm \
yum-metadata-parser-1.1.2-4.el5.x86_64.rpm
5. 修改配置文件
mv /etc/yum.repos.d/rhel-debuginfo.repo /etc/yum.repos.d/rhel-debuginfo.repo.bak
vi /etc/yum.repos.d/rhel-debuginfo.repo
[base]
name=Red Hat Enterprise Linux $releasever -Base
baseurl=http://mirrors.163.com/centos/5/os/$basearch/
gpgcheck=1
[update]
name=Red Hat Enterprise Linux $releasever -Updates
baseurl=http://mirrors.163.com/centos/5/updates/$basearch/

6、清理yum源
yum clean all
7、yum install vim #测试一下可不可以用
至此yum安装完成,可以 yum install 安装程序了
