RUN RAILS SERVER ON PORT 443

- May 16, 2018

If we want to run the rails application in port 443 :-

I have added the below line in /config/environments/production.rb:

config.force_ssl = true

Now I have tried the below attempts:

Start rails on 3000

SSL=true rails s -e production -p 3000

It runs rails on https://project.com but 404 error on http://project.com

Start rails on 443 and mentioned the same port in script:

rvmsudo rails s -p 443
Start rails on 80 and 443 both using two different pid:
rvmsudo rails s -p 80 -P PID1
rvmsudo rails s -p 443 -P PID2

4.Finally I have tried to forward request to 3000 from 443 and 80:

sudo iptables -t nat -I PREROUTING -p tcp --dport 80 -j REDIRECT --to-ports 3000
sudo iptables -t nat -I PREROUTING -p tcp --dport 443 -j REDIRECT --to-ports 3000
