The best way to have something run on boot is use an init script. Assuming you are using Ubuntu, you can use Upstart to write it in a simple declarative format. A quick example might look like:

description "Daemon for flask project"



start on (local-filesystems and net-device-up IFACE=eth0)

stop on runlevel [!12345]



# If the process quits unexpectedly trigger a respawn

respawn



setuid myuser

setgid mygroup

chdir /path/to/dir



exec  uwsgi --master \

     --processes 4 \

     --die-on-term \

     --socket /tmp/uwsgi.sock

Save the file to "/etc/init/myservice.conf" It will now launch on boot once the filesystem is mounted and the network is active. You can also manage it like other services, using:

service myservice start

service myservice restart

service myservice stop
