Bash Script: Auto Configure vmware-tools at Boot time


This post is originally posted on my colleague Michel aka ‘HighKing’ blog: http://highking.nl/website/auto-config_vmware-tools

When you install a new kernel on a RHEL/CentOS VM, you need to reconfigure the vmware-tools using the ‘vmware-config-tools.pl’ script. I have created a simple script that does this automatically, so you don’t have to be there when the kernel is updated (handy for automatically updating machines).

Place this in a script called ‘check-vmware-tools’ in /etc/init.d:

#!/bin/bash
#
# check-vmware-tools
#
# chkconfig:   - 00 99
# description: Check whether or not the vmware-tools are installed at boot time.
# processname: check-vmware-tools
#

loadvmxnet() {
  if [ "`uname -i`" != "x86_64" ]; then 
        echo -n "Reloading vmxnet driver... "
        /sbin/rmmod pcnet32
        /sbin/rmmod vmxnet
        /sbin/depmod -a
        /sbin/modprobe vmxnet
        echo "done"
  fi
}

case $1 in
  start)
    echo -n $"Checking VMware-tools: "
   if [ ! -e /lib/modules/`/bin/uname -r`/misc/vmci.ko ]; then
      echo "Not available, running vmware-config-tools..."
      /usr/bin/vmware-config-tools.pl --default && loadvmxnet
   else
     echo "OK"
   fi
  ;;
  *)
    echo "Usage: $0 start"
    exit 1
  ;;
esac


Make it writeable with:

chmod +x /etc/init.d/check-vmware-tools


Next is to make it known by chkconfig with:

chkconfig --add check-vmware-tools


Now we have done that, we can simply enable it with:

chkconfig check-vmware-tools on

On the next boot, this script checks whether or not the vmware-tools are configured for the running kernel (by checking if vmmemctl.ko is in place). If not, it runs ‘vmware-config-tools.pl and reboots after that.

You can download the file here: check-vmware-tools

    Very useful stuff, will save me quite some time 😉
    Only one question, why didn’t you use the Invoke-VMScript cmdlet to push this automatically to all your RH guests ?
