node.js - Issue on LEMP configuration and how can i redirect to NodeJS request to NGINX -

i configured lemp server on ubuntu nodejs i'm getting following error on browser.

"the page looking temporarily unavailable.

please try again later." how can redirect nodejs request nginx .can please me how can sort out these issues.

if nginx work through php-fpm (fastcgi process manager) can uncomment important part php location ~ \.php$ {} stanza in default vhost defined in file

vi /etc/nginx/sites-available/default

like

[...]  location ~ \.php$ {                 fastcgi_split_path_info ^(.+\.php)(/.+)$;                 fastcgi_pass 127.0.0.1:9000;                 fastcgi_index index.php;                 include fastcgi_params;         }  [...] 

and nodejs can modify same vhost file

vi /etc/nginx/sites-available/default

and add lines below location ~ \.php$ {} stanza like

[...]         location /testapp/ {         proxy_pass  http://localhost:3000/;         proxy_set_header host $host;         proxy_set_header x-real-ip $remote_addr;         proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for;     } [...] 

from can forwarding port node.js app nginx

now can access page url http://localhost/testapp/ instead of http://localhost:3000/ 

hope work you
