CENTOS 5.4, there is Karnel panic

[J Cole]

i have a server that will not boot, CENTOS 5.4, there is Karnel panic, unable to load SELint policy.

The problem was after upgrade Plesk to 9.5 the email would not work and I reboot. It will not boot

How do i install a fix without boot up the michine.
I need to instal kernel-2.6.18-194.el5.i686.rpm

Am not a pro.

Try to boot with any Linux LiveCD, mount your disk and edit /etc/sysconfig/selinux with

SELINUX=disabled

After that try to boot with your kernel.

Hello, I got it boot.
in the boot setting i add enforcing=0 and after boot i add enforcing=0 to /etc/grub.conf

Here is a small script for this.

#!/bin/bash

# This file will load at every start (add to /etc/rc.local)
# Will verify if the kernel is different with the older started kernel and send a mail to you.
# in /boot/grub/grub.conf you need to put panic=5

# Checking whether Root Runs the Application
if [ "$(id -u)" != "0" ]; then
echo "This script must be run as root !" 1>&2
exit 1
fi
MAIL='YOURMEMAIL-HERE' // edit this line

RUNKERNEL=`uname -a |awk '{print $3}'`
FILEKERNEL='/etc/krnversion'


# If Kernel Version File does not exist, create it from the current running kernel
if [ ! -f $FILEKERNEL ]; then
echo $RUNKERNEL > $FILEKERNEL
else
GETFILEKERNEL=`cat $FILEKERNEL`
# if the file exists, compare the running kernel with the one on file and if they differ, update the kernel record file with the current kernel & notify the administration
if [ "$RUNKERNEL" != "$GETFILEKERNEL" ]; then
echo $RUNKERNEL > $FILEKERNEL
echo "!!! Warning !!!

Difference found in Kernel Versions between the Running Kernel Version and the Kernel Version File !
This probably happened because of a Kernel Upgrade or the loading of an Older Kernel to compensate for a newer Kernel panic.
Please check the versions below, make a determination and act accordingly:

Running Kernel Version is $RUNKERNEL while the Kernel Version on File is $GETFILEKERNEL

* However, the Kernel Version File was updated to match the Running Kernel Version *
