Hi I am deploying rails application to digital ocean VPS, I have followed https://coderwall.com/p/yz8cha this blog , all things done well, but now the browser shows only
a blank white page
In nginx log file it shows
invalid host in upstream "/tmp/unicorn.testvpsdo.sock" in /etc/nginx/sites-enabled/testvpsdo:2
What causes the error?,
this is my nginx.conf file
upstream unicorn {
server unix:/tmp/unicorn.testvpsdo.sock fail_timeout=0;
}
server {
listen 80 default_server deferred;
# server_name example.com;
root /home/navin/apps/testvpsdo/current/public;
location ^~ /assets/ {
gzip_static on;
expires max;
add_header Cache-Control public;
}
try_files $uri/index.html $uri #unicorn;
location #unicorn {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://unicorn;
}
error_page 500 502 503 504 /500.html;

I followed Deploying a Rails App on Ubuntu 14.04 with Capistrano, Nginx, and Puma to deploy a Rails app to Digital Ocean.
It suggested to keep nginx.conf (/etc/nginx/sites-enabled/medical-app) as
upstream puma {
server unix:///home/myappuser/apps/medical-app/shared/tmp/sockets/medical-app-puma.sock;
}
server {
listen 80 default_server deferred;
# server_name example.com;
root /home/myappuser/apps/medical-app/current/public;
access_log /home/myappuser/apps/medical-app/current/log/nginx.access.log;
error_log /home/myappuser/apps/medical-app/current/log/nginx.error.log info;
location ^~ /assets/ {
gzip_static on;
expires max;
add_header Cache-Control public;
}
try_files $uri/index.html $uri #puma;
location #puma {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://puma;
}
error_page 500 502 503 504 /500.html;
client_max_body_size 10M;
keepalive_timeout 10;
}
and than I added domain and than installed SSL using let's encrypt
which changed the nginx.conf (/etc/nginx/sites-enabled/medical-app) as following
upstream puma {
server unix:///home/myappuser/apps/medical-app/shared/tmp/sockets/medical-app-puma.sock;
}
server {
listen 80 default_server deferred;
# server_name example.com;
root /home/myappuser/apps/medical-app/current/public;
access_log /home/myappuser/apps/medical-app/current/log/nginx.access.log;
error_log /home/myappuser/apps/medical-app/current/log/nginx.error.log info;
location ^~ /assets/ {
gzip_static on;
expires max;
add_header Cache-Control public;
}
try_files $uri/index.html $uri #puma;
location #puma {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://puma;
}
error_page 500 502 503 504 /500.html;
client_max_body_size 10M;
keepalive_timeout 10;
}
server {
# server_name example.com;
root /home/myappuser/apps/medical-app/current/public;
access_log /home/myappuser/apps/medical-app/current/log/nginx.access.log;
error_log /home/myappuser/apps/medical-app/current/log/nginx.error.log info;
location ^~ /assets/ {
gzip_static on;
expires max;
add_header Cache-Control public;
}
try_files $uri/index.html $uri #puma;
location #puma {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://puma;
}
error_page 500 502 503 504 /500.html;
client_max_body_size 10M;
keepalive_timeout 10;
server_name www.medtib.com medtib.com; # managed by Certbot
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/www.medtib.com/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/www.medtib.com/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
server {
if ($host = medtib.com) {
return 301 https://$host$request_uri;
} # managed by Certbot
if ($host = www.medtib.com) {
return 301 https://$host$request_uri;
} # managed by Certbot
listen 80 ;
server_name www.medtib.com medtib.com;
return 404; # managed by Certbot
}
Now https is working fine but if I enable force SSL through Rails config
config.force_ssl = true
Than it gives error page not working with message redirected too many times
and if I try to login with Facebook which requires https than it gives following error
I don't have idea about nginx etc.
You should forward X-Forwarded-Proto header to your application to inform your application which protocol used. (https, http)
Put the following:
proxy_set_header X-Forwarded-Proto $scheme;
Before:
proxy_pass http://puma;
It should do the trick.
I have a rails project that I just deployed to my AWS server. But when I access the IP address of the instance it returns:
The webpage has a redirect loop
This is my nginx conf file
/etc/nginx/conf.d/myapp.conf
upstream unicorn {
server unix:/tmp/sockets/unicorn.sock
fail_timeout=0;
}
server {
listen 80;
server_name 12.34.56.78;
root /home/ubuntu/var/www/myapp/current/public;
return 301 http://12.34.56.78$request_uri;
access_log on;
}
server {
listen 443 default;
server_name 12.34.56.78;
root /home/ubuntu/var/www/myapp/current/public;
location ^~ /assets/ {
gzip_static on;
expires max;
add_header Cache-Control public;
}
try_files $uri/index.html $uri #unicorn;
location #unicorn {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off; proxy_pass http://unicorn;
}
error_page 500 502 503 504 /500.html;
client_max_body_size 20M;
keepalive_timeout 10;
}
I am using nginx + unicorn.
Can anybody shed some light into what I might be doing wrong here. Any help will be greatly appreciated.
Thank you.
I'm messing around with aws, and want to deploy multiple apps to my free tier aws account.
I'd like to have nginx point to "ec-2-site.com/first-app" and "ec-2-site.com/second-app.
Here are my current config files (basically guess and checking from this railscast
upstream unicorn_chaos {
server unix:/tmp/unicorn.chaos.sock fail_timeout=0;
}
upstream unicorn_blog {
server unix:/tmp/unicorn.blog.sock fail_timeout=0;
}
server {
listen 80 default deferred;
location /chaos/ {
#server_name http://ec2-50-16-81-170.compute-1.amazonaws.com/chaos;
root /home/deployer/apps/chaos/current/public;
location ^~ /assets/ {
gzip_static on;
expires max;
add_header Cache-Control public;
}
try_files $uri/index.html $uri #unicorn;
location #unicorn {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://unicorn_chaos;
}
error_page 500 502 503 504 /500.html;
client_max_body_size 4G;
keepalive_timeout 10;
}
location /blog/ {
# server_name example.com;
root /home/deployer/apps/blog/current/public;
location ^~ /assets/ {
gzip_static on;
expires max;
add_header Cache-Control public;
}
try_files $uri/index.html $uri #unicorn;
location #unicorn {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://unicorn)blog;
}
error_page 500 502 503 504 /500.html;
client_max_body_size 4G;
keepalive_timeout 10;
}
}
Here is the error I'm getting:
nginx: [emerg] named location "#unicorn_chaos" can be on the server level only in /etc/nginx/sites-enabled/chaos:23
Obviously that #unicorn_appname directive shouldn't be there, but where should it be? Am I going bout this all wrong?
Thanks
I didn't check the railscast but I've found some problems in your configuration.
First is on line 50 you misspelled the address.
Second is that you should put named locations out of the locations.
Your hierarchy looks like this
server
location app1
try_files #unicorn
location #unicorn
proxy_pass unicorn_app1
location app2
try_files #unicorn
location #unicorn
proxy_pass unicorn_app2
Try this
server
location app1
try_files unicorn_app1
location #unicorn_app1
proxy_pass unicorn_app1
location app2
try_files #unicorn_app2
location #unicorn_app2
proxy_pass unicorn_app2
The important is to keep their names unique, and put them in the same server level.
This is my nginx.conf file
upstream unicorn {
server unix:/tmp/unicorn.blog.sock fail_timeout=0;
}
server {
listen 80 default deferred;
# server_name example.com;
root /home/deployer/apps/blog/current/public;
location ^~ /assets/ {
gzip_static on;
expires max;
add_header Cache-Control public;
}
try_files $uri/index.html $uri #unicorn;
location #unicorn {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://unicorn;
}
error_page 500 502 503 504 /500.html;
client_max_body_size 4G;
keepalive_timeout 10;
}
I tried to add SSL - I redeplyed and restarted NGINX and the server. I undid everything redeployed and it was back up.... Now I tried the same thing. Tried to add SSL it failed. Undid. Now server is down. Here is the github with revisions!
Ran /etc/init.d/unicorn_blog start and restarted unicorn. It worked
I have been able to deploy my rials app into a vps system using nginx, unicorn and capistrano with no errors. Now, i want to deploy another rails app using the same nginx config(the two scripts are below) inside the same vps server and after running cap deploy:setup and cap deploy:cold it sets up correctly and the rails app is sent to the server. The problem i get is this. when i type service nginx restart i get the following error
nginx: [emerg] duplicate upstream "unicorn" in /etc/nginx/sites-enabled/cf:1
nginx: configuration file /etc/nginx/nginx.conf test failed
my nginx script for the first app which is currently running is
upstream unicorn {
server unix:/tmp/unicorn.cf.sock fail_timeout=0;
}
server {
listen 80 default deferred;
server_name cfmagazineonline.com;
root /home/deployer/apps/cf/current/public;
location ^~ /assets/ {
gzip_static on;
expires max;
add_header Cache-Control public;
}
try_files $uri/index.html $uri #unicorn;
location #unicorn {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://unicorn;
}
error_page 500 502 503 504 /500.html;
client_max_body_size 4G;
keepalive_timeout 10;
}
my nginx config for the second rails app which fails to run but instead trows an error for the first rails app and makes it to crash is
upstream unicorn {
server unix:/tmp/unicorn.gutrees.sock fail_timeout=0;
}
server {
listen 80 default deferred;
server_name gutrees.com;
root /home/deployer/apps/gutrees/current/public;
location ^~ /assets/ {
gzip_static on;
expires max;
add_header Cache-Control public;
}
try_files $uri/index.html $uri #unicorn;
location #unicorn {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://unicorn;
}
error_page 500 502 503 504 /500.html;
client_max_body_size 4G;
keepalive_timeout 10;
}
any ideas how i can fix this issue and set up the virtual host correctly. Thank you
Name your second apps upstream differently (upstream names need to be unique). So instead of unicorn use i.e. the name #my_shiny_app_server. Then use this name proxy_pass directive http://my_shiny_app_server. Replace the my_shiny string with the name of your app e.g. gutrees, cf.
