redhat5.2 x64上使用yum
今天（010115）帮朋友在他的redhat5.2的服务器上用centos的yum替换原有的，测试成功，记录一下：
1、看看系统：
uname -a
Linux hostname 2.6.18-92.el5 #1 SMP Tue Apr 29 13:16:15 EDT 2008 x86_64 x86_64 x86_64 GNU/Linuxcat /etc/redhat-release Red Hat Enterprise Linux Server release 5.2 (Tikanga)
2、卸载掉自带的yum：
rpm -aq|grep yum|xargs rpm -e --nodeps
3、 下载centos的安装包
wget http://ftp.sjtu.edu.cn/centos/5/os/x86_64/CentOS/yum-3.2.8-9.el5.centos.1.noarch.rpmwget http://ftp.sjtu.edu.cn/centos/5/os/x86_64/CentOS/yum-3.2.22-20.el5.centos.noarch.rpmwget http://ftp.sjtu.edu.cn/centos/5/os/x86_64/CentOS/yum-metadata-parser-1.1.2-3.el5.centos.x86_64.rpmwget http://ftp.sjtu.edu.cn/centos/5/os/x86_64/CentOS/yum-fastestmirror-1.1.16-13.el5.centos.noarch.rpmwget http://ftp.sjtu.edu.cn/centos/5/os/x86_64/CentOS/python-iniparse-0.2.3-4.el5.noarch.rpm
4、生成/etc/yum.repos.d/CentOS-Base.repo 文件，内容如下：
[base]name=CentOS-5 - Basebaseurl=http://ftp.sjtu.edu.cn/centos/5/os/x86_64/gpgcheck=1gpgkey=http://ftp.sjtu.edu.cn/centos/RPM-GPG-KEY-centos5#released updates[update]name=CentOS-5 - Updatesbaseurl=http://ftp.sjtu.edu.cn/centos/5/updates/x86_64/gpgcheck=1gpgkey=http://ftp.sjtu.edu.cn/centos/RPM-GPG-KEY-centos5#packages used/produced in the build but not released[addons]name=CentOS-5 - Addonsbaseurl=http://ftp.sjtu.edu.cn/centos/5/addons/x86_64/gpgcheck=1gpgkey=http://ftp.sjtu.edu.cn/centos/RPM-GPG-KEY-centos5#additional packages that may be useful[extras]name=CentOS-5 - Extrasbaseurl=http://ftp.sjtu.edu.cn/centos/5/extras/x86_64/gpgcheck=1gpgkey=http://ftp.sjtu.edu.cn/centos/RPM-GPG-KEY-centos5#additional packages that extend functionality of existing packages[centosplus]name=CentOS-5 - Plusbaseurl=http://ftp.sjtu.edu.cn/centos/5/centosplus/x86_64/gpgcheck=1enabled=0gpgkey=http://ftp.sjtu.edu.cn/centos/RPM-GPG-KEY-centos5#contrib - packages by Centos Users[contrib]name=CentOS-5 - Contribbaseurl=http://ftp.sjtu.edu.cn/centos/5/contrib/x86_64/gpgcheck=1enabled=0gpgkey=http://ftp.sjtu.edu.cn/centos/RPM-GPG-KEY-centos5
5、换了一个Key
rpm --import http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
