Todavía no conozco nginx. Un chico de Devops instaló uno hace un tiempo para nuestra aplicación.
esta es la nginx.confconfiguración.
user www-data;
worker_processes auto;
pid /run/nginx.pid;
events {
worker_connections 768;
multi_accept on;
}
http {
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
include /etc/nginx/mime.types;
default_type application/octet-stream;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
ssl_prefer_server_ciphers on;
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;
gzip on;
gzip_disable "msie6";
proxy_cache_path /home/html_catch levels=1:2 keys_zone=appbacktocartcocatch:2m max_size=50m;
proxy_cache_key "$scheme$request_method$host$request_uri$is_args$args";
proxy_cache_valid 200 302 10m;
proxy_cache_valid 404 1m;
include /etc/nginx/sites-enabled/*.conf;
}
Puedo ver que hay includeotros archivos como este que son específicamente para la aplicación.
#proxy_cache_path /home/html_catch levels=1:2 keys_zone=appbacktocartcocatch:2m max_size=50m;
#proxy_cache_key "$scheme$request_method$host$request_uri$is_args$args";
#proxy_cache_valid 200 302 10m;
#proxy_cache_valid 404 1m;
upstream appbacktocartco {
# server localhost:3000;
server localhost:3001;
}
server {
listen 145.239.24.196:80;
server_name app.backtocart.co;
location / {
proxy_cache appbacktocartcocatch;

proxy_set_header X-Forwarded-Proto $scheme;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_pass http://appbacktocartco;
proxy_read_timeout 90;
}
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/app.backtocart.co/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/app.backtocart.co/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
if ($scheme != "https") {
return 301 https://$host$request_uri;
} # managed by Certbot
}
Ahora solo necesito ejecutar otra aplicación como esta en el puerto 5000. Simplemente copié este archivo, intenté cambiar algunas cosas, luego reinicié nginx pero obtuve algunos errores que no entiendo. ¿Me puede ayudar con esto?
EDITAR
Esta es solo una forma que probé
# proxy_cache_path /home/html_catch levels=1:2 keys_zone=appbacktocartcocatch:2m max_size=50m;
# proxy_cache_key "$scheme$request_method$host$request_uri$is_args$args";
# proxy_cache_valid 200 302 10m;
# proxy_cache_valid 404 1m;
upstream appbacktocartco {
# server localhost:3000;
server localhost:5000;
}
server {
listen 145.239.24.196:80;
server_name chatservice.backtocart.co;
location / {
proxy_cache chatservicebacktocartcocatch;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_pass http://chatservicebacktocartco;
proxy_read_timeout 90;
}
}
Entonces lo hago
/etc/init.d/nginx restart
y obten

Tu error está en los archivos de configuración donde configuras los upstreams:
upstream appbacktocartco {
# server localhost:3000;
server localhost:5000;
}
Tienes que usar diferentes nombres para el upstream para que esto funcione.
También en el segundo archivo de configuración que usas
proxy_pass http://chatservicebacktocartco;
que debe coincidir con el correspondiente aguas arriba.
Además, el mensaje de error ( nginx: [emerg] duplicate upstream "appbacktocartco") indica que esto es un problema.
