Now my question is what are the commands for Centos to fetch ,update and install, all the packages installed on the server. I would like to use Yum. Any help would be great.
"yum update" will do it for you. Normally, you will not need to reboot after updating, unless you update the kernel or several other packages that require a reboot.
Also, if a package that is currently running has been updated, or that package is currently using a package which has been updated and you want the currently running things to start using the new stuff _now_, you'll want to restart those packages. Until those packages end, disk space and ram memory is not finally freed.
Sometimes it is hard to tell if that situation exists and a re-boot is just faster and certainly simpler than identifying, stopping, starting tons of stuff.
Often, in a desktop environment, just a telnet 3, telnet 5 command sequence will get most of that done. Faster than reboot, takes care of desktop related stuff without the manual investigate, kill, start steps.
