I have a node.js application that I start using forever like so:
NODE_ENV=production forever start index.js
I've also worked out how to setup crontab to automatically start the forever command for this application on server reboot:
@reboot /usr/local/bin/forever start /path/to/my/app/index.js
The only problem here is the node environment. How do I add the production environment to the crontab command?
If you need to execute a special command with variables etc. in a crontab it's easier to write a simple shell script and call that script from the crontab:
#!/bin/bash
export NODE_ENV=production
/usr/local/bin/forever start /path/to/my/app/index.js
Make it executable: chmod 755 /usr/local/bin/start_my_app.sh
Then in your crontab:
@reboot /usr/local/bin/start_my_app.sh
If you want to set just one environment variable, you could use the export command right before the forever command.
@reboot export NODE_ENV=production; /usr/local/bin/forever start /path/to/my/app/index.js
For more than one variable Sukima's method is better.
