I am trying to deploy my website to amazon ec2 using nginx,puma and capistrano i followed this tutorial https://medium.com/#henslejoseph/deployment-a-rails-app-to-ec2-using-bitbucket-and-semaphoreci-d539bea90db3 the application got deployed to server but when i trying to access it via browser by going to website url it says This site can’t be reached.The next thing i tried is checking the nginx and the puma logs i dont find anythig in nginx logs but in puma_access.log there is error Errno::EADDRINUSE: Address already in use - bind(2) for "0.0.0.0" port 3000.After this i tried checking if any process is using the port 3000 using lsof -wni tcp:3000 and netstat -an | grep 3000 but the output was empty seems there is no process attached to port.
I am trying to debug it from 3 days but still clue less what is going.Any help is greatly appreciated I am just enclosing my all my config files for reference.

Can someone help me where i am going wrong have tried all stackoverflow questions and googled a lot from 3 days still no idea whats wrong with my config.
Update: After a lot of research i got the solution
all you have to do is ensure that the default file in sites_available folder should also be available in sites_enabled folder.This default file ensures that the website is enabled.If the default file is not available it seems like nginx is not listening on port 80.

I have followed the tutorial here on ow to deploy a Rails App using Capistrano and Puma. I had initially used with a Rails 4 and all worked fine, however I'm now trying with Rails 5 App and is not working. I've made some changes due to changes in Capistrano (I've also upgraded Capistrano) and now I'm stuck as the deployment does not seem to create the sock file while deploying and I get the following error:

I have setup the capistrano script to deploy on staging. I cant seem to find a way to restart the puma server as deployment gets completed and to restart the puma server if server is rebooted for any reason.
I am using rails 4.2 and Ubuntu 16.04 on ec2 server. I tried upstart script with puma-manager but I think its not supported on ubuntu 16.04.

I had an issue like this once. I ended up adding the rails server instance as a daemon using this command every time I deploy
cd current/app_dir
rails s -d -p 3000 -e 'production'
PS: I kill the current running rails instance before doing this
I'm using capistrano for deploy my rails application, but I got the following error:
Skipping task `sidekiq:restart'.
Capistrano tasks may only be invoked once. Since task `sidekiq:restart' was previously invoked, invoke("sidekiq:restart") at config/deploy.rb:49 will be skipped.
If you really meant to run this task again, first call Rake::Task["sidekiq:restart"].reenable
THIS BEHAVIOR MAY CHANGE IN A FUTURE VERSION OF CAPISTRANO. Please join the conversation here if this affects you.
https://github.com/capistrano/capistrano/issues/1686
Besides that, I think the command is not working even on the first time, since sidekiq is not running. I could start it manually, but I believe even if not running, it should start anyway, right?
My deploy/production.rb:
# server-based syntax
# ======================
# Defines a single server with a list of roles and multiple properties.
# You can define all roles on a single server, or split them:
set :stage, :production
set :full_app_name, "#{fetch(:application)}_#{fetch(:stage)}"
# Using remote cache to deploy
set :deploy_via, :remote_cache
server '35.160.22.104', user: 'ubuntu', roles: %w{app db web}
# role-based syntax
# ==================
# Defines a role with one or multiple servers. The primary server in each
# group is considered to be the first unless any hosts have the primary
# property set. Specify the username and a domain or IP for the server.
# Don't use `:all`, it's a meta role.
# role :app, %w{deploy#example.com}, my_property: :my_value
# role :web, %w{user1#primary.com user2#additional.com}, other_property: :other_value

# These variables are then only loaded and set in this stage.

Any help would be appreciated. Thanks!
For me, setting pty to false worked. Still don't know why, but if someone does, would appreciate a explanation on comments. Thanks!
I'm trying to configure nginx with puma to server my Ruby on Rails application. Whenever I visit my page I get a 502 bad gateway error.

You have nginx communicating with your puma server via socket
/home/deploy/apps/puma-api/shared/tmp/sockets/puma-api-puma.sock
You have puma creating this socket at
set :puma_bind, "unix://#{shared_path}/tmp/sockets/#{fetch(:application)}-puma.sock"
I can't see shared_path defined anywhere in your code though. Make sure that these two match (or just hardcode the path to eliminate variables for now).
I would also first check if /home/deploy/apps/puma-api/shared/tmp/sockets/puma-api-puma.sock even exists.
