systemd has the concept of targets as a more flexible replacement for runlevels in sysvinit.

Runlevel 3 is emulated by multi-user.target. runlevel3.target is a symbolic link to multi-user.target.

You can switch to 'runlevel 3' by running

# systemctl isolate multi-user.target 

Another option is to use kernel command line arguments.

On boot, systemd activates the target unit default.target whose job is to activate services and other units by pulling them in via dependencies. systemd parses its own kernel command line argument systemd.unit=.

This may be used to temporarily boot into the multi-user.target boot unit:

systemd.unit=multi-user.target


-------------
Open a terminal and (as root) run:

systemctl set-default multi-user.target

or with --force

systemctl set-default -f multi-user.target

to overwrite any existing conflicting symlinks1.

Double-check with:

systemctl get-default

Another way is to add the following parameter to your kernel boot line:

systemd.unit=multi-user.target
