Redhat5.8 替换yum源
Redhat5.8替换yum源
老版本支持起来，还是挺麻烦的，何况是32位，/(ㄒoㄒ)/~~，把过程分享出来，供参考。
1、卸载RedHat自带yum：
#rpm-qa|grepyum|xargsrpm-e--nodeps
注：
a、xargs是一条Unix和类Unix操作系统的常用命令。它的作用是将参数列表转换成小块分段传递给其他命令，以避免参数列表过长的问题
b、--nodeps强制卸载,不管依赖性
2、下载yum相关软件
http://vault.centos.org/5.8/os/i386/CentOS/下载
yum-3.2.22-39.el5.centos.noarch.rpmyum-fastestmirror-1.1.16-21.el5.centos.noarch.rpmyum-metadata-parser-1.1.2-3.el5.centos.i386.rpm
3、安装
rpm-ivhyum*
注意一起安装，否则会报错，相互依赖的错误
4、备份配置文件，删除原有文件
cp-rf/etc/yum.repos.d//etc/yum.repos.d_bak
cd/etc/yum.repos.d/
rm*
5、下载163镜像源
wgethttp://mirrors.163.com/.help/CentOS5-Base-163.repo
到/etc/yum.repos.d/
修改为以下内容：
[base]
name=CentOS-$releasever-Base-163.com
baseurl=http://vault.centos.org/5.8/os/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
#releasedupdates

name=CentOS-$releasever-Updates-163.com
baseurl=http://vault.centos.org/5.8/updates/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates

baseurl=http://vault.centos.org/5.8/centosplus/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus
gpgcheck=1

gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
#contrib-packagesbyCentosUsers
[contrib]
name=CentOS-$releasever-Contrib-163.com
baseurl=http://vault.centos.org/5.8/contrib/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=contrib
gpgcheck=1

gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
因为163的源已经不支持5.x版本了，用yum下载会报大量404，所以切换到了vault.centos.org。
7、运行
yumcleanall
yummakecache
8、总结
其实这么折腾，安装软件是方便了，但很多软件都比较老，还需要手动安装，升级。
