Thanks again, i did the change, i follow this steps : http://www.linuxtopia.org/online_books/centos5/centos5_administration_guide/ centos5_s1-swap-adding.html#s2-swap-creating-file
But I setup bs=1M count=1024 this I learn it from: https://help.ubuntu.com/community/SwapFaq#head-75ffcb00cefe143fc380f84d7ea92 03f16a596d0 I like it more to do it that way.
Later I reboot my PC and run the command free, it seems that now I am using my newly created swap file, what a nice start. My linux experience is starting to like it more, thanks to all for your help, thoughts and time!

partition, thanks in

How much swap do you currently have? You may not need to increase swap at all.
If you do - I haven't tried this method in CentOS (or any OS) but it should work:
https://help.ubuntu.com/community/SwapFaq#head-75ffcb00cefe143 fc380f84d7ea92 03f16a596d0
It creates a swap file instead of a swap partition. Much easier than finding unpartitioned space ...
Yes and with today's kernels it provides the same level of performance.
# dd if=/dev/zero of=/.swapfile bs=1M count=512
# mkswap /.swapfile
fstab: /.swapfile swap swap defaults 0 0
Or if you use lvm, turn swapoff the lv, lvresize the lv, mkswap the lv again, then swapon the lv and you have a larger swap, but the swapfile will at least be contiguous.
