Installing Yum On RHEL 3

預設REHL3似乎不會安裝yum 所以要自己手動安裝

1.先確認有無以下套件

python-elementtree

python-sqlite

python-urlgrabber

sqlite

rpm  –qa  |grep  python-xxxxxx

沒有的話請先安裝

wget http://updater.ismile.net/centos/4.4/os/i386/CentOS/RPMS/yum-2.4.3-1.c4.noarch.rpm

wget http://updater.ismile.net/centos/4.4/os/i386/CentOS/RPMS/python-elementtree-1.2.6-4.2.1.i386.rpm

wget http://updater.ismile.net/centos/4.4/os/i386/CentOS/RPMS/python-sqlite-1.1.7-1.2.i386.rpm

wget http://updater.ismile.net/centos/4.4/os/i386/CentOS/RPMS/python-urlgrabber-2.9.8-2.noarch.rpm

wget http://updater.ismile.net/centos/4.4/os/i386/CentOS/RPMS/sqlite-3.3.3-1.2.i386.rpm

2.Download yum套件(yum-2.0.8-1.rpm)

http://linux.duke.edu/projects/yum/download/2.0/yum-2.0.8-1.noarch.rpm
注意，不同版本的OS安裝的yum版本也不同

3.安裝yum
rpm  –ivh  yum-2.0.8-1.noarch.rpm

4.設定yum.conf

vi /etc/yum.conf  設定如下：

[main]
cachedir=/var/cache/yum
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=redhat-release
tolerant=1
exactarch=1

#base]
#ame=Red Hat Linux $releasever - $basearch - Base
#aseurl=http://mirror.dulug.duke.edu/pub/yum-repository/redhat/$releasever/$basearch/
[base]
name=CentOS-$releasever - Base
baseurl=http://mirror.centos.org/centos/3/os/i386/
gpgcheck=1

[updates]
name=Red Hat Linux $releasever - Updates
baseurl=http://mirror.centos.org/centos/3/updates/i386/
gpgcheck=1

5.Downloaded  gpg key金鑰

 http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-3

6. 輸入金鑰

rpm --import RPM-GPG-KEY-CentOS-3

7. 開始update

yum –y update.
