Question

How can I change my Rails application to run in production mode  Is there a config file  environment rb for example  to do that

User · Answer

rails s -e production   This  will run the server with RAILS ENV    production    Apart from this you have to set the assets path in production rb  config serve static assets   true   Without this your assets will not be loaded

How to setup and run a Rails 4 app in Production mode  step-by-step  using Apache and Phusion Passenger   Normally you would be able to enter your Rails project  rails s  and get a development version of your app at http   something com 3000  Production mode is a little trickier to configure   I ve been messing around with this for a while  so I figured I d write this up for the newbies  such as myself   There are a few little tweaks which are spread throughout the internet and figured this might be easier    Refer to this guide for core setup of the server  CentOS 6  but it should apply to nearly all Linux flavors   https   www digitalocean com community tutorials how-to-setup-a-rails-4-app-with-apache-and-passenger-on-centos-6 Make absolute certain that after Passenger is set up you ve edited the  etc httpd conf httpd conf file to reflect your directory structure  You want to point DocumentRoot to your Rails project  public folder Anywhere in the httpd conf file that has this sort of dir   var www html your application public needs to be updated or everything will get very frustrating  I cannot stress this enough  Reboot the server  or Apache at the very least - service httpd restart   Enter your Rails project folder  var www html your application and start the migration with rake db migrate  Make certain that a database table exists  even if you plan on adding tables later  this is also part of step 1   RAILS ENV production rake secret - this will create a secret key that you can add to config secrets yml   You can copy paste this into config secrets yml for the sake of getting things running  although I d recommend you don t do this  Personally  I do this step to make sure everything else is working  then change it back and source it later  RAILS ENV production rake db migrate RAILS ENV production rake assets precompile if you are serving static assets  This will push js  css  image files into the  public folder  RAILS ENV production rails s   At this point your app should be available at http   something com whatever instead of  3000  If not  passenger-memory-stats and see if there an entry like 908  469 7 MB  90 9 MB  Passenger RackApp   var www html projectname  I ve probably missed something heinous  but this has worked for me in the past

It is not a good way to run rails server in production environment by  rails server -e production   because then rails runs as a single-threaded application  and can only respond to one HTTP request at a time   The best article about production environment for rails is Production Environments - Rails 3

You can also pass the environment to script server     script server -e production

for default server   rails s -e production  for costum server port   rails s -p  port  -e production  eg  rails s -p 3002 -e production

User · Answer

If you re running on Passenger  then the default is to run in production  in your apache conf    lt VirtualHost   80 gt    ServerName application name rails local   DocumentRoot   Users rails application name public    RailsEnv production    This is the default  lt  VirtualHost gt    If you re just running a local server with mongrel or webrick  you can do     script server -e production   or in bash   RAILS ENV production   script server   actually overriding the RAILS ENV constant in the enviornment rb should probably be your last resort  as it s probably not going to stay set  see another answer I gave on that
