Linode reboots hell. How do I restart all my Linux service on reboot. Help needed!!

# systemctl enable <service>
That should take care of it

@gnaaah Works well. Thanks. What of my routines such as golang programs. Not system services

Well you could make a service for that and have it also start like that.
Creating a service for systemd is really easy and there are tons of tutorials out there.
If you use Go along with a web framework I suggest installing a module for your web server (nginx or apache) and let them do the bootstrapping
