Ich kenne Nginx noch nicht. Ein DevOps-Typ hat vor einiger Zeit eines für unsere App eingerichtet.
dies ist das nginx.confSetup.
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;
}
Ich kann sehen, dass es includeeinige andere Dateien wie diese sind, die speziell für die App sind
#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 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 $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_pass http://appbacktocartco;
proxy_read_timeout 90;
}
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/app.backtocart.co/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/app.backtocart.co/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
if ($scheme != "https") {
return 301 https://$host$request_uri;
} # managed by Certbot
}
Jetzt muss ich nur noch eine andere App wie diese auf Port 5000 ausführen. Ich habe diese Datei einfach kopiert, versucht, ein paar Dinge zu ändern, dann habe ich nginx neu gestartet, aber es sind einige Fehler aufgetreten, die ich nicht verstehe. Können Sie mir dabei helfen?
BEARBEITEN
Hier ist nur eine Möglichkeit, die ich versucht habe
# 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;
}
}
Dann mach ich
/etc/init.d/nginx restart
und bekomme
[....] Restarting nginx (via systemctl): nginx.serviceJob for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.

Antwort1
Ihr Fehler liegt in den Konfigurationsdateien, in denen Sie die Upstreams konfigurieren:
upstream appbacktocartco {
# server localhost:3000;
server localhost:5000;
}
Damit dies funktioniert, müssen Sie für den Upstream andere Namen verwenden.
Auch in der zweiten Konfigurationsdatei verwenden Sie
proxy_pass http://chatservicebacktocartco;
welche mit dem entsprechenden Upstream übereinstimmen muss.
Auch die Fehlermeldung ( nginx: [emerg] duplicate upstream "appbacktocartco") nennt dies als Problem.
