Lab12: Software Installation

Lab Tasks:

1. Runlevels

· Make Runlevel 3 your default Runlevel

If you have an /etc/inittab file, edit it. Locate the following line:

id:2:initdefault:

Change the number after the first colon to the runlevel you want to be the default.

However, most people won't have that file, in which case you should edit /etc/init/rc-sysinit.conf instead and change the following line:

env DEFAULT_RUNLEVEL=2



· Initiate the single user Runlevel from GRUB console and try to change the root password

Choose the "(recovery mode)" option from GRUB; add "-s", "S" or "single" to the kernel command-line; or from a running machine, run "telinit 1" or "shutdown now".
