How to restart RoR services after server has been rebooted
- by Alan DeLonga
Update I have been searching around to see what services would possibly need to be restarted in my project after reboot. One of them was thinking sphinx, which I finally got to the point where it logs:
[Fri Nov 16 19:34:29.820 2012] [29623] accepting connections
But I still cant run searchd or searchd --stop because there was no generated sphinx.conf file in the etc/sphinxsearch for more info refer to this open thread on thinking_sphinx after reboot
I then turned to looking into restarting unicorn or thin based on some insight I got. The issue is when I check my gems I see one for thin AND unicorn. But when I try to start either one of them they have no file residing in etc/init.d/ where the nginx and sphinxsearch files reside...
Would rebooting totally erase the files for an app server like thin or unicorn? We are hosted on Rackspace running
ruby 1.9.2p290
rails (3.2.8, 3.2.7, 3.2.0)
nginx/1.1.19
notice that there are gems for unicorn and thin but there is no unicorn.rb or thin.rb in my config folder for my app... I am still super lost if any one can give me some insight on some steps to take to figure this out I would really appreciate it. Anything would help, thanks for reading.
thin 1.4.1
unicorn 4.3.1
When I run unicorn I get the same issue as referenced here :
> /usr/local/bin/unicorn start
/usr/local/lib/ruby/gems/1.9.1/gems/unicorn-4.3.1/lib/unicorn/configurator.rb:610:in `parse_rackup_file': rackup file (start) not readable (ArgumentError)

from /usr/local/bin/unicorn:19:in `<main>'
When I run thin it just opens a command line prompt...
/usr/local/bin/thin start

I am working on a project that was built by another group. I made some modifications to a constants file in the config folder (changing some values for arrays that populated some drop down fields), but the app had to be rebooted before those changes would be recognized. The hosting is through Rackspace, we rebooted through the option on their site. I contacted them and checked the status of our server, the port is open and operational. The problem is the app is not running when you go to the address for the site. Then when I put in the ip address of the server it just says "Welcome to Nginx". But in a log files I see:
[Thu Nov 15 02:34:37.945 2012] [15916] caught SIGTERM, shutting down
[Thu Nov 15 02:34:37.996 2012] [15916] shutdown complete
I am not very versed in server side set up. I have also never worked on a Rails project that had to have specific services started before the application will start. Any insight as to how to figure out what services need to be restarted and how to go about restarting them would be greatly appreciated. I feel kind of dead in the water at this point...
Thanks,
Alan
