اگر اشتباه نکنم ۳ روز پیش بود که میخواستم ورژن php رو آپدید کنم (yum upgrade php) که با خطای -bash: yum: command not found مواجه شدم ، من هم دست به کار نصب yum شدم ولی دیدم که چند بسته دیگه قبل از نصب بسته rpm مربوط به yum نیاز هست ، که خود اون ها هم بسته های رو نیاز داشتن ! آخر سر با کلی سرچ توی گوگل و تست های مکرر ، تونستم yum رو نصب کنم !

کد های زیر روی لینوکس centos 5.3 x86_64 و مجازی ساز openvz تست شده

wget http://mirror.centos.org/centos/5/os/x86_64/CentOS/yum-3.2.22-26.el5.centos.noarch.rpm

و حالا نصب ، البته میشد ۲ مرحله رو یک جا انجام داد :

rpm -Uvh gmp-4.1.4-10.el5.x86_64.rpm
rpm -Uvh readline-5.1-3.el5.x86_64.rpm
rpm -Uvh python-2.4.3-27.el5.x86_64.rpm
rpm -Uvh libxml2-2.6.26-2.1.2.8.x86_64.rpm

rpm -Uvh python-urlgrabber-3.1.0-5.el5.noarch.rpm
rpm -Uvh yum-metadata-parser-1.1.2-3.el5.centos.x86_64.rpm
rpm -Uvh python-iniparse-0.2.3-4.el5.noarch.rpm
rpm --nodeps -Uvh yum-fastestmirror-1.1.16-14.el5.centos.1.noarch.rpm
rpm -Uvh yum-3.2.22-26.el5.centos.noarch.rpm

آخر سر هم yum -y update رو بزنید .
