systemctl-enable

Enable a service to run on boot

$ systemctl enable [unit]

$ systemctl enable [unit] --now

$ systemctl enable [unit] --user

systemctl [OPTIONS...] enable UNIT...

systemctl enable creates symbolic links in systemd directories to enable units to start automatically at boot (for system units) or at login (for user units). This does not start the unit immediately; use --now to both enable and start.
The symlinks are created based on the [Install] section of the unit file, typically linking into target.wants directories. Enabling is idempotent; enabling an already-enabled unit has no effect.

--now

Also start the unit after enabling

Enable user service manager units instead of system units

Do not reload systemd configuration after enabling

Enable units even if they are masked

Enable temporarily until next reboot only

Requires root privileges for system units. Enabling does not start the unit; combine with --now or use systemctl start separately. Masked units cannot be enabled without --force.
