redhat5.9配置yum

今天折腾了一天，首先配置yum的时候一直不正确，后来看到一篇帖子说需要卸载redhat自带的yum，重新安装，我卸载之后（rpm -aq|grep yum|xargs rpm -e --nodeps），安装的时候特别困难，一直无限的依赖，当时异常烦躁，后来细心检查发现是版本的问题。

1、安装YUM

网易的镜像地址是http://mirrors.163.com/centos/5.9/os/x86_64，注意5.9是版本，

cat /etc/issue查看主机版本是redhat5.9，uname -a或者getconf LONG_BIT可以查出主机是64位机器，所以，下载所需的rpm时一定要选对版本。

需要的rpm包为：

yum-3.2.27-14.el6.centos.noarch.rpm

yum-metadata-parser-1.1.2-14.1.el6.x86_64.rpm

yum-plugin-fastestmirror-1.1.26-11.el6.noarch.rpm

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

具体文件名要去http://mirrors.163.com/centos/5.9/os/x86_64/CentOS/查看

用wget命令下载rpm包，

rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm
rpm -ivh yum-metadata-parser-1.1.2-14.1.el6.x86_64.rpm
rpm -ivh yum-3.2.27-14.el6.centos.noarch.rpm um-plugin-fastestmirror-1.1.26-11.el6.noarch.rpm  
注意最后两个包必需同时安装，否则会相互依赖(这句是帖子里的原话，我并没有遇到这个问题)

2、配置网易源

mv /etc/yum.repos.d/rhel-debuginfo.repo /etc/yum.repos.d/rhel-debuginfo.repo.repo.bak

vi /etc/yum.repos.d/rhel-debuginfo.repo

内容为：

[base]

name=CentOS-$releasever - Base

baseurl=http://mirrors.163.com/centos/5.9/os/$basearch/

gpgcheck=1

gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-5

name=CentOS-$releasever - Updates

[centosplus]

name=CentOS-$releasever - Plus

baseurl=http://mirrors.163.com/centos/5.9/centosplus/$basearch/

gpgcheck=1

enabled=0

注意：文本中的5.9是版本， gpgkey的版本也要是5

测试：yum list|grep vim

发现yum配置成功
