Install-and-config-strong-pm.md

Install Node.js on Ubuntu 14.04

curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -
sudo apt-get install -y nodejs
node --version
sudo apt-get install -y build-essential

Install strong-pm

sudo npm install -g strong-pm
sudo sl-pm-install
sudo /sbin/initctl start strong-pm

You can edit the configuration file here:

//In this file you can add env variables and change the deployment port
sudo vi /etc/init/strong-pm.conf

By default the application is deployed on this path

cd /var/lib/strong-pm/svc/1/work/current

Also you can see the application logs here:

tail -f /var/log/upstart/strong-pm.log

Install Nginx

sudo apt-get update
sudo apt-get install nginx
sudo service nginx start

With Nginx you can put you API in an specific domain intead of 3001 port, for this you need to create a config file for your domain:

sudo vi /etc/nginx/sites-available/my.domain.com

--START File content--
server {
        listen 80;
        server_name my.domain.com;

        access_log /var/log/nginx/api_access.log;
        error_log /var/log/nginx/api_error.log;

        location / {
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header Host $http_host;
                proxy_pass http://127.0.0.1:3001;
        }
}
--END--

server {
        listen 80;

        root /usr/share/nginx/html;
        index index.html;


        location /explorer/ {
                proxy_set_header Host $http_host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_pass http://127.0.0.1:3001/explorer/;
        }

        location /api/ {
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_pass http://127.0.0.1:3001/api/;
        }


        location / {
                try_files $uri $uri/ =404;
        }

}

After that you need to link the config file to the sites-enabled folder

sudo ln -s /etc/nginx/sites-available/my.domain.net /etc/nginx/sites-enabled/

Also you need to change this line in the nginx config file

sudo vi /etc/nginx/nginx.conf

--START File content--
server_names_hash_bucket_size 64;
--END--

Restart the nginx service

sudo service nginx restart

well done!
