upstart

i have written an upstart script for ubuntu to launch my node.js server manually or on startup. But it always terminates with status 127 and i can't find more information about what is going wrong. If i execute it manually then it works and i also tested it on ubuntu 12.10 where it also works ... it only fails to work on ubuntu 10.04 which is the production server i'm using. The script: description "" author "" start on started mountall stop on shutdown respawn respawn limit 20 5 # Max open files are @ 1024 by default. Bit few. limit nofile 32768 32768 env HOME=/home/projects/<project_name>

The scenario: System running on a server consisting of a Python/Flask web application and background tasks using Celery Both web application and celery workers are run as upstart jobs (Web app behind Nginx) Deployment to production is done with a script that: Stop the upstart jobs Push code to server Run any db migrations Start the upstart jobs How can I enhance the deployment script so it does the following?: Tell the celery worker to stop accepting tasks Wait until any currently running celery tasks are finished Stop the upstart jobs Push code to server Run any db migrations Start the

I really enjoy using upstart. I currently have upstart jobs to run different gunicorn instances in a number of virtualenvs. However, the 2-3 examples I found for Celery upstart scripts on the interwebs don't work for me. So, with the following variables, how would I write an Upstart job to run django-celery in a virtualenv. Path to Django Project: /srv/projects/django_project Path to this project's virtualenv: /srv/environments/django_project Path to celery settings is the Django project settings file (django-celery): /srv/projects/django_project/settings.py Path to the log file for this

I have a websocket service. it's strage that have error:"too many open files", but i have set the system configure: /etc/security/limits.conf * soft nofile 65000 * hard nofile 65000 /etc/sysctl.conf net.ipv4.ip_local_port_range = 1024 65000 ulimit -n //output 6500 So i think my system configure it's right. My service is manage by supervisor, it's possible supervisor limits? check process start by supervisor: cat /proc/815/limits Max open files 1024 4096 files check process manual start: cat /proc/900/limits Max open files 65000 65000 files The reason is used supervisor manage serivce. if i

I've created small web server using werkzeug and I'm able to run it in usual python way with python my_server.py . Pages load, everything works fine. Now I want to start it when my pc boots. What's the easiest way to do that? I've been struggling with upstart but it doesn't seem to "live in a background" cuz after I execute start my_server I immediately receive kernel: [ 8799.793942] init: my_server main process (7274) terminated with status 1 my_server.py: ... if __name__ == '__main__': from werkzeug.serving import run_simple app = create_app() run_simple('0.0.0.0', 4000, app) upstart

I have written a module in Python and want it to run continuously once started and need to stop it when I need to update other modules. I will likely be using monit to restart it, if module has crashed or is otherwise not running. I was going through different techniques like Daemon , Upstart and many others. Which is the best way to go so that I use that approach through out my all new modules to keep running them forever? From your mention of Upstart I will assume that this question is for a service being run on an Ubuntu server. On an Ubuntu server an upstart job is really the simplest and
