Upstart and Logging? about exrm

[bitwalker]

Thanks for the kind words!

Regarding an upstart config, I think your best reference for an implementation would be @smpallen99's exrm plugin for building RPMs from a release. He has a script which handles the start/stop/restart stuff. It'll likely be very similar to what you need.

As for logging. Logs are currently pushed to a log directory in the root of your release directory, so on the same level as bin, lib, and releases. There is barely any configuration provided by default, other than telling sasl to log only errors. I'm going to push a change so that sasl logs to log/myapp.log instead, which should be more useful. If you use other logging facilities, you'll need to configure them by adding the relevant configuration settings to myapp.schema.exs and myapp.conf. You can also put configuration in config.exs, but then you won't be able to configure the logging via your .conf file. If you need more info, just let me know!

My exrm_rpm plugin creates an rpm that does two things to handle service starting on Redhat Linux distributions:

• It creates an init script and puts it in /etc/init.d, allowing you to manage the service
• It does the chkconfig so the service will be automatically started when the linux server starts up

If you need just the init script on a system without the rpm build tools, you can install the plugin and run mix release --rpm on the system. It will create the init script without the rpm build tools.

If you find the plugin useful, but missing something, let me know.

Although I have not tested this yet, I was planning on using the erlang auto restart capabilities to automatically restarting the application if the erlang vm crashes. I still have to verify that the application is started with the correct settings to ensure this works.

Thanks guys... I'll take a look at the repo and see if I can get the Upstart script working on Ubuntu.

@smpallen99 The current boot script sets up the heartbeat monitor, but I don't know if all of the configuration is in place, or if perhaps it's already working. Some testing is likely needed for that scenario. Let me know what you find out on that front!

@malkomalko I'm closing this for now. If you have any updates or want to open this up for discussion again, feel free to reopen!
