It is always a good idea to run your python projects via paster + nginx. Some time ago I wrote about building environment for pylons projects on ubuntu, so that shouldn’t be a problem. Now… let create some kind of script to start, stop and restart our application.

so…

sudo touch /etc/init.d/our_project
sudo chown +x /etc/init.d/out_project

and now…

sudo vim /etc/init.d/our_project

and put some code in it:


#!/bin/bash -e

PYTHON_ENV=/mnt/python2.5-env/our_project # our pve (python environment)
APP_NAME=our_project # application name
APP_PATH=/mnt/our_project # path to our project
INI_FILE=production.ini # ini file, that we want to use

case "$1" in
  start)
    echo -e "\nConfiguration in use: ${APP_PATH}/${INI_FILE}\n\nStarting ${APP_NAME}..."
    cd ${APP_PATH}
    ${PYTHON_ENV}/bin/paster serve --daemon --pid-file=/var/run/${APP_NAME}.pid --log-file=/var/log/${APP_NAME}.log ${APP_PATH}/${INI_FILE} start
    ;;
  stop)
    echo -e "\nConfiguration in use: ${APP_PATH}/${INI_FILE}\n\nStopping ${APP_NAME}..."
    cd ${APP_PATH}
    ${PYTHON_ENV}/bin/paster serve --daemon --pid-file=/var/run/${APP_NAME}.pid --log-file=/var/log/${APP_NAME}.log ${APP_PATH}/${INI_FILE} stop
    ;;
  restart)
    echo -e "\nConfiguration in use: ${APP_PATH}/${INI_FILE}\n\nRestarting ${APP_NAME}..."
    cd ${APP_PATH}
    ${PYTHON_ENV}/bin/paster serve --daemon --pid-file=/var/run/${APP_NAME}.pid --log-file=/var/log/${APP_NAME}.log ${APP_PATH}/${INI_FILE} restart
    ;;
  *)
    echo "Usage: $0 {start|stop|restart}"
    exit 1
esac

and now run an application:
