There are a few ways that you can switch into different runlevels. One way to do it is by the init method.
init 3
The above command would put me into runlevel 3. Running the runlevel command after completion would verify the runlevel we’re currently in.
runlevel
If you wanted to switch to runlevel 1 you could simply just run init 1 as such.
init 1
You can also change the default runlevel that your system starts up on by editing the inittab file.
vi /etc/inittab
Once in the above file. You’ll see the last line contains
id:3:initdefault:
You can change the above number 3 to any runlevel number you wish to change it to.
You can also after rebooting edit your grub menu manually to enter a specified runlevel. For instance, when you see the grub menu appear type the letter e to edit the selection and then choose the kernel line and press e again to edit that line. Lastly you’d want to just add in a space followed by the number runlevel you wish to enter.
