SOLVED : Redhat Linux boot interactive mode service startup


Usually , during Linux boot-up process - enabled services are automatically started in the order of service sequence. Sometimes during debugging or recovery it may be required to start services interactively - one by one. RedHat Linux supports this option - as described in below steps.


  • Login to console 
  • Boot Linux
  • After the Redhat kernel image splash screen  appears & Filesystems are mounted - continuously press hold letter  ' I ' (case -insensitive) 
  • If continuous press hold doesn't work out , keep pressing the letter I multiple times.
  • Services startup enters into Interactive mode as shown in below snapshot
  • Required services may be started using the options Yes/No/Continue options.


Hope this may be useful to some debugging strange services !!
