NGINX SET UP following : https://www.digitalocean.com/community/tutorials/how-to-install-nginx-on-ubuntu-12-04-lts-precise-pangolin
#ssh into droplet ssh root@174.138.80.13
-installed nginx sudo apt-get install nginx
-started nginx sudo service nginx start
-confirm nginx has started ifconfig eth0 | grep inet | awk '{ print $2 }'
-ensure nginx will be up after reboot update-rc.d nginx defaults
-How To Host Multiple Node.js Applications On a Single VPS with nginx, forever, and crontab -https://www.digitalocean.com/community/tutorials/how-to-host-multiple-node-js-applications-on-a-single-vps-with-nginx-forever-and-crontab -setting up nginx and node were prereqs to this
#Reason for a reverse proxy: Reverse proxies can operate wherever multiple web-servers must be accessible via a single public IP address. The web servers listen on different ports in the same machine, with the same local IP address or, possibly, on different machines and different local IP addresses altogether. The reverse proxy analyzes each incoming request and delivers it to the right server within the local area network.
-create a file for your desired domain config nano /etc/nginx/conf.d/sweetgrassconstruction.com.conf
-copy the following into the conf file: server { listen 80;
server_name sweetgrassconstruction.com;
location / { proxy_pass http://localhost:3000; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection 'upgrade'; proxy_set_header Host $host; proxy_cache_bypass $http_upgrade; } }
-to be able to reference multiple domains for one Node.js app (like www.example.com and example.com) nano /etc/nginx/nginx.conf
-add to http block: server_names_hash_bucket_size 64;
-OPEN A NEW TERMINAL WINDOW FOR THE FOLLOWING :
-create cronjob to restart application if VPS gets rebooted -navigate to root folder of sweetgrass touch starter.sh -add to starter.sh, pointing to location of our server script: #!/bin/sh
if [ $(ps -e -o uid,cmd | grep $UID | grep node | grep -v grep | wc -l | tr -s "\n") -eq 0 ] then export PATH=/usr/local/bin:$PATH forever start --sourceDir /opt/live/sweetgrass server.js >> /path/to/log.txt 2>&1 fi -add, commit and push to master branch of github
-push master to DO git push live master
-BACK TO SSH TERMINAL WINDOW :
-To start cron script at each reboot you need to edit the crontab with this command: crontab -e -select nano editor -append the following code : @reboot /opt/live/sweetgrass/starter.sh -restart the nginx webserver service nginx restart -check to see if it restarted service nginx status
