I have written a simple automation script for deploying and restarting my twisted application on remote Debian host. But I have an issue with starting using twistd.
I have a run.tac file and start my application as follows inside fabric task:
@task
def start():
run("twistd -y run.tac")
And then just fab -H host_name start. It works great on localhost but when I want to start application on remote host I get nothing. I can see in log file that application is actually launched, but factory is not started. I've also checked netstat -l - nothing is listening my port.
I've tried to run in non-daemon mode, like so twistd -ny run.tac, and, voila, factory started and I can see it in netstat -l on remote host. But that is not the way I want it to work cause it. Any help is appreciated.
There was an issue reported sometime back which is similar to this.
It also suggested that it seems to succeed with the option pty=False. Can you try and check that?
run("twistd -y run.tac", pty=False)
Some more pointers from the FaQ:
