如何在后台运行Play的dist文件？

Question

When I deployed my play application I built the package using:

dist

This created a file that I can run on my server like:

sudo ./bin/app-name -Dhttp.port=9090

This works fine for testing but how can I run this process in the background?

I will eventually have to use upstart or some sort of process monitoring tool to make sure this process is running after server reboots etc.

Using play 2.3.x

Answer 1

Since you are on ubuntu

sudo ./bin/app-name -Dhttp.port=9090 & 

should do the trick.

Ceating the upstart script is also fairly easy https://askubuntu.com/questions/18802/how-to-correctly-add-a-custom-daemon-to-init-d In your case it would be in /etc/init/app-name.conf and look like

# app-name
#   

start on stopped rc RUNLEVEL=[2345]
stop on runlevel [!2345]

respawn
exec $PATH_TO_APP/bin/app-name -Dhttp.port=9090

Of course you will want to change the RUNLEVEL and the PATH_TO_APP

Answer 2

That of course depends on the system at which you're deploying the app, anyway in general you need to run it as a deamon.

Refer to your system's documentations, I'm pretty sure that you will find tutorial very soon.
