If you are seeing this error I am getting an error upon running ./install_amp from a fresh svn source.
It’s complaining about a non-existent MySQL column being addressed:

Please Reload Asterisk by browsing your server.

Then you need to issue the following from the command line ./install_amp –force-version 2.1.1

Ok so you have ran a yum -y update and you now have a new kernel loaded on your system.

If you want to remove an older kernel version, and make no other changes to your system so as not to clutter up your bootloader.

First check wich one you’re using: uname -r

List them all: rpm -qa | grep -i kernel

Remove what you don’t need: rpm -e kernel_version
