Startup script for debian-based linux for running node app when rebooting from /etc/init.d
When my vps was rebooted occassionally by the hosting provider, my node.js app was not coming back online. This script can be used in /etc/init.d/node-app which will allow rc.d to restart your app when the machine reboots without your knowledge.
If you are using mongodb, redis, or nginx, you want to add those to your default run-level as well.
Clone the repo
git clone https://github.com/chovy/node-startup.git
cd node-startup/init.d
Edit the node-app script with your settings for node path, node environment (ie: production or development), path to application directory (where your app.js is - this is also NODE_APP variable), and a path to a pid file.
vi node-app
NODE_EXEC=/usr/local/bin/node
NODE_ENV="production"
NODE_APP="app.js"
APP_DIR='/var/www/example.com';
PID_FILE=$APP_DIR/pid/app.pid
LOG_FILE=$APP_DIR/log/app.log
By default, it expects the pid file to be in /var/www/example.com/pid/app.pid and your log file to be in /var/www/example.com/log/app.log
Copy the startup script node-app to your /etc/init.d directory
sudo bash -l
cp ./init.d/node-app /etc/init.d/
Test that it all works:
/etc/init.d/node-app start
/etc/init.d/node-app restart
/etc/init.d/node-app stop
Add node-app to the default runlevels
update-rd.c node-app defaults
Finally, reboot to be sure app starts automatically
reboot
If there is a app.pid file already, but node is not running, and you try to start it will not start. You will have to manually remove the .pid file and run it again.
