The ESX-POST-SCRIPT script

That's everything that happens before the reboot sorted out.  What we've go so far is a network configuration that's personalised for the server, a disk-partition and VMDK container that's personalised for the server, and a configuration-script.

Now that the server is also rebooted, we have full access to all the ESX tools, so we can do the final configuration.

The sole role of esx-post-script.sh is basically to create a runnable esxcfg.sh file that contains all the standard ESX commands for setting up a host.

esx-post-script
  1. ESXID=$1 
  2. ESXCODE=`printf "%02d\n"  "$ESXID"` 
  3. ESXHOSTNAME="ESX-$ESXCODE" 
  4. ESXSCIP="10.20.30.$ESXID" 
  5.  
  6. ESXSTORAGEIP="10.10.30.$ESXID" 
  7.  
  8. cat > /esxcfg.sh <<eofcfg>
  9.  
  10. # MORE CONFIG WILL GO HERE, THAT COMES LATER 
  11.  
  12. EOFcfg 
  13.  
  14.  
  15. cp -f /etc/rc.d/rc.local /etc/rc.d/rc.local.bak 
  16. cat > /etc/rc.d/rc.local << EOFrc 
  17. chmod a+x esxcfg.sh 
  18. bash /esxcfg.sh > /root/post_install.log 
  19. cp -f /etc/rc.d/rc.local /etc/rc.d/rc.postinstall 
  20. cp -f /etc/rc.d/rc.local.bak /etc/rc.d/rc.local 
  21. EOFrc  
  

  1. esx-post-script.sh creates a new customised script esxcfg.sh
  2. esx-post-script.sh backs up the current /etc/rc.init file
  3. esx-post-script.sh puts esxcfg.sh into rc.init
