＝ 對付 CentOS 的YUM ＝

很奇異的
到網站上找到專屬RedHat EL 4 的
yum-2.4.2-0.4.el4.rf.noarch.rpm套件
無法正常安裝

但使用原本應屬於RedHat EL 3 的
yum-2.0.8-0.1.el3.rf.noarch.rpm
卻能使用

到此搜尋下載


正常抓取檔案後，導入GPG-KEY

rpm -import http://isoredirect.centos.org/centos/RPM-GPG-KEY-CentOS-4
rpm -import http://isoredirect.centos.org/centos/RPM-GPG-KEY-centos4

再到/etc/yum.conf來加上下面一大段...
(el4或CentOS適用版本)

--------------------
[main]
cachedir=/var/cache/yum
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=redhat-release

[base]
name=CentOS-$releasever - Base
baseurl=http://ftp.riken.jp/Linux/caos/centos/4.4/os/$basearch/
gpgcheck=1

#released updates
[update]
name=CentOS-$releasever - Updates
baseurl=http://ftp.riken.jp/Linux/caos/centos/4.4/updates/$basearch/
gpgcheck=1

#packages used/produced in the build but not released
[addons]
name=CentOS-$releasever - Addons
baseurl=http://ftp.riken.jp/Linux/caos/centos/4.4/addons/$basearch/
gpgcheck=1
cachedir=/var/cache/yum
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=redhat-release
tolerant=1
exactarch=1
--------------------

之後第一動作
yum update yum(先更新yum再說)
再來就隨你高興了
yum update -y
