Nginx + Passenger to serve rails apps in different sub URIs - ruby-on-rails

Question

I'm running a rails app in a Debian server (ip 192.168.1.193) with passenger as a standalone
$ cd /home/hector/webapps/first
$ passenger start -a 127.0.0.1 -p 3000
And I want to serve this app throw Nginx with reverse proxy in a different sub folder as:
http://192.168.1.193/first
My nginx.conf server:
...
server {
listen 80;
server_name 127.0.0.1;
root /home/hector/webapps/first/public;
passenger_base_uri /first/;
location /first/ {
proxy_pass http://127.0.0.1:3000;
proxy_set_header Host $host;
}
}
...
Then I run the Nginx server
$ /opt/nginx/sbin/nginx
With one rails app running with this configuration everything seems to work ok.
But when I try to add my second app
$ cd /home/hector/webapps/second
$ passenger start -a 127.0.0.1 -p 3001
with this nginx.conf file:
...
server {
listen 80;
server_name 127.0.0.1;
root /home/hector/webapps/first/public;
passenger_base_uri /first/;
location /first/ {
proxy_pass http://127.0.0.1:3000;
proxy_set_header Host $host;
}
}
server {
listen 80;
server_name 127.0.0.1;
root /home/hector/webapps/second/public;
passenger_base_uri /second/;
location /second/ {
proxy_pass http://127.0.0.1:3001;
proxy_set_header Host $host;
}
}
…
and I reload the Nginx server configuration
$ /opt/nginx/sbin/nginx -s reload
nginx: [warn] conflicting server name "127.0.0.1" on 0.0.0.0:80, ignored
I get a warning and I cannot access the second app from
http://192.168.1.193/second/
The server returns 404 for the second app and the first app is still running.

I think you just have to put both locations into the same server:
server {
listen 80;
server_name 127.0.0.1;
location /first/ {
root /home/hector/webapps/first/public;
passenger_base_uri /first/;
proxy_pass http://127.0.0.1:3000/;
proxy_set_header Host $host;
}
location /second/ {
root /home/hector/webapps/second/public;
passenger_base_uri /second/;
proxy_pass http://127.0.0.1:3001/;
proxy_set_header Host $host;
}
}
