actually last night my friend ask me to configure his centos vps which is dont have yum (i know, i'm noob and i cant work centos out without YUM)

so, here is the quick way to install YUM-my package manager in less then 10 minutes

download all this shit rpms into one folder name "yummy"

wget http://mirror.centos.org/centos/5/os/x86_64/CentOS/m2crypto-0.16-6.el5.1.x86_64.rpm

wget http://mirror.centos.org/centos/5/os/x86_64/CentOS/python-elementtree-1.2.6-5.x86_64.rpm

wget http://mirror.centos.org/centos/5/os/x86_64/CentOS/python-sqlite-1.1.7-1.2.1.x86_64.rpm

wget http://mirror.centos.org/centos/5/os/x86_64/CentOS/python-urlgrabber-3.1.0-2.noarch.rpm

wget http://mirror.centos.org/centos/5/os/x86_64/CentOS/rpm-python-4.4.2-47.el5.x86_64.rpm

wget http://mirror.centos.org/centos/5/os/x86_64/CentOS/yum-3.0.5-1.el5.centos.5.noarch.rpm

wget http://mirror.centos.org/centos/5/os/x86_64/CentOS/yum-metadata-parser-1.0-8.fc6.x86_64.rpm

wget http://mirror.centos.org/centos/5/os/x86_64/CentOS/sqlite-3.3.6-2.x86_64.rpm

(my friend server is 64bit, if your server is 32bit, just replace x86_64 with i386

example: http://mirror.centos.org/centos/5/os/i386/CentOS/m2crypto-0.16-6.el5.1.i386.rpm

good, now we are going to install all those rpms

rpm -Uvh *.rpm

if this not working, just install those rpms one by one.

wallah, now it's done. you can type yum now!

note: if you got this error Could not find any working storages.

try this magic command line

rpm -Uvh --replacepkgs sqlite-3.3.6-2.x86_64.rpm
