PAE enabled kernels are necessary on some configurations with 4GB of RAM or more. PAE enables the system to recognize the ram and display it. Non-pae kernels will only show around 3.2gb of RAM.
This is only for an RH-based OS (FC, Centos, etc..):
As root, run:
yum install kernel-PAE
After that's setup, edit your /boot/grub/grub.conf file to select the newly installed kernel.
Then reboot the system and that's it!
Just a note that while editing the grub.conf file, be sure to set the 'default' parameter to correspond to the correct placement of your PAE kernel. Usually, it'll be the first one since it was installed last. So, have it say this:
default=0
grub counts kernels like 0,1,2,3 so the first kernel is 0 and so forth.
If 'yum -y install kernel-PAE' says no packages are found, edit /etc/yum.conf and delete the 'kernel-pae' and 'kernel-PAE' from the exclude line. Then try it again.
I recently switched to AYK Solutions from Softlayer for my dedicated server requirements. I received a much better specification server at significantly reduced cost from what Softlayer could offer me, with many of the previously 'extra' features at Softlayer included in the base price offered by AYK. The support was second to none, and they were extremely helpful in transferring all of my old server accounts over for no additional fee whatsoever.
Dedicated Semi-Managed Server Review I've been using AYKSolutions for about 2 years now and their support and servers have been great. They assisted me with the transition of all my websites and databases from my old server onto their system with no problem. If I ever need them for support or a change they respond fast and always keep me up to date with the status of my support ticket. I highly recommend using this company especially if you're looking for someone to assist with server management. Best of all their cost is great!
