Manual Deployment with nginx and puma

Manual Deployment with nginx and puma

Link I used i the following steps  is https://www.digitalocean.com/community/tutorials/how-to-deploy-a-rails-app-with-puma-and-nginx-on-ubuntu-14-04 and this link http://ruby-journal.com/how-to-setup-rails-app-with-puma-and-nginx/

Also a useful link to do this properly is http://nicolas-brousse.github.io/ubuntu-install-and-tips/pages/installation/rails-puma/


1. Install DBMS (postgre, mysql) and install rvm, ruby, rails and there dependencies

2. clone the git repository to any location ideally in home

3. cd myapp

4. bundle install

4. RAILS_ENV=production rake db:create

5. RAILS_ENV=production rake db:migrate

6. RAILS_ENV=production rake assets:precompile

7. Make sure you have gem puma in the Gem file then 

8. cd ~
wget https://raw.githubusercontent.com/puma/puma/master/tools/jungle/upstart/puma-manager.conf
wget https://raw.githubusercontent.com/puma/puma/master/tools/jungle/upstart/puma.conf


9. vi puma.conf

In the puma.conf file look for

setuid deploy
setgid deploy        where deploy is the user of the linux you can using to deploy


10. sudo cp puma.conf puma-manager.conf /etc/init


11. sudo vi /etc/puma.conf    (in the file add the complete path to the app)


12. Start the puma manager sudo start puma-manager

13. Install nginx

14. sudo vi /etc/nginx/sites-available/default


15. Copy this text

upstream app {
    # Path to Puma SOCK file, as defined previously
    server unix:///tmp/my_app.sock fail_timeout=0;
}

server {
    listen 80;
    server_name localhost;

    root /home/deploy/appname/public;

    try_files $uri/index.html $uri @app;

    location @app {
        proxy_pass http://app;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_redirect off;
    }

    error_page 500 502 503 504 /500.html;
    client_max_body_size 4G;
    keepalive_timeout 10;
}


then 

16 restart the server sudo service nginx restart

17. Start puma server

bundle exec puma -e production -d -b unix:///tmp/my_app.sock

18. ps aux | grep puma

19. To kill puma server

20. kill -s SIGTERM 9594
