I have the entire CentOS repo on a server here.
??? so you made a 40+ gig repo ????? and put it on some server someplace , instead of using the already supported and updated Cent repos ?
then you are trying to use this for a OFFLINE and NOT connected to the net computer.
the full lamp stack is in the base cent repo and in on the centos5.5 install dvd ( though the install dvd IS OUT OF DATE )
there is an option to install all of this on the install screens when you first install cent 5.5
also this is not the right command "yum list all"
that lists ALL the rpms installed on the computer
vikas027 posted the wrong commands
unSpawn was asking about this -- and this would have been the command to run
in rhel5/CentOS 5 there ARE A BUNCH of conflicting repos
some are NOT binary compatible , that is why the yum plugin "priories" is SO VERY IMPORTANT to set up and have configured CORRECTLY
this is what vikas027 should have posted
yum clean all
sometimes , do to yum /python error, the "rpm --rebuilddb " needs to be ran first
remember that CentOS5/RHEL 5 is and was DESIGNED for the headless server first and foremost , then the office/laboratory secondly .
