nginx error /home/deploy/myapp/current/public/" is forbidden - ruby-on-rails

Question

I tried the solution of a similar question and many other on stackoverflow but none of them seem to solve this issue. The default niginx "Welcome" page was running even when I configured /etc/nginx/passenger.conf and /etc/nginx/passenger.conf. It was after I configured the /etc/nginx/sites-enabled/default, by changing the default path to my rails app, I started getting 403 forbidden error.
This is the error log.
2017/02/20 06:05:17 [error] 27311#27311: *2 directory index of "/home/deploy/Blog/current/public/" is forbidden, client: 111.93.247.206, server: mydomain.com, request: "GET / HTTP/1.1", host: "35.154.168.57"
My nginx files are as follows.

Please can somebody tell what am I doing wrong or what have I not done?
Thank You

Answer 1

Follow these steps:
Backup /home/deploy/Blog/current/public
chown -R <nginxuser>:<nginxuser> /home/deploy/Blog/current/public
nginxuser: the user that runs nginx, its probably one of the following: nginx, www-data, root.

Not sure what exactly you missing. Please align yourself with my setup on https://www.wiki11.com.
Your issue is coming because nginx is trying to search for index.html file into /home/deploy/apps/mll/current/public which is not present there.
In order to fix, you will need to add passenger with your nginx.
Instructions to follow.
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 561F9B9CAC40B2F7
sudo apt-get install -y apt-transport-https ca-certificates
Add Passenger APT repository
sudo sh -c 'echo deb https://oss-binaries.phusionpassenger.com/apt/passenger xenial main > /etc/apt/sources.list.d/passenger.list'
sudo apt-get update
Install passenger and nginx
sudo apt-get install -y nginx-extras passenger
Now start nginx webserver.
sudo service nginx start
Next, we need to update the Nginx configuration to point Passenger to the version of Ruby that we're using.
sudo vim /etc/nginx/nginx.conf
And add or uncomment
include /etc/nginx/passenger.conf;
Save and close nginx.conf. Then open /etc/nginx/passenger.conf
sudo vim /etc/nginx/passenger.conf
If you are using .rbenv, then
passenger_ruby /home/deploy/.rbenv/shims/ruby;
Or if you are using rvm, then
passenger_ruby /home/deploy/.rvm/wrappers/ruby-2.5.0/ruby;
Or if you are using system ruby, then
passenger_ruby /usr/bin/ruby;
Next, restart nginx server
sudo service nginx restart
Add passenger_enabled on; into your site-enabled/centers or site-enabled/nodeapp file.
server {
listen 80;
listen [::]:80;
root /home/deploy/apps/mll/current/public;
index index.html index.htm;
server_name myrailssite.com;
passenger_enabled on;
location / {
try_files $uri $uri/ =404;
}
}
Restart nginx server again, sudo service nginx restart. Hopefully it should work.
