How to start rails server in production mode using unicorn and config file?

Question

I add Gem 'unicorn' to Gemfile and call rails server unicorn -e production , but I get a load error. Then I add Gem 'unicorn_rails' , then call rails server unicorn -e production , but I can't find the socket file. So I am considering if it doesn't use the config/unicorn.rb file as the configuration? So I call unicorn_rails -c config/unicorn.rb -E production -D , but I get another error text file busy .

So now I am stuck in this matter, could you help me? :)

Answer 1

It should be something looks like:

bundle exec unicorn -E production -c config/unicorn.rb

and you should only need unicorn gem

Answer 2

bundle exec unicorn -p $PORT -c ./config/unicorn.rb

works for me

I put it in the Procfile and then use Foreman to start it off by entering

foreman start

Answer 3

web: bundle exec unicorn -p $PORT -c ./config/unicorn.rb

service unicorn_projectName start

works for me
