Nginx returns 502 if service not ready on start


Nginx returns 502 if service not ready on start

Any of those help After reviewing the Nginx logs at /var/log/nginx/error.log I could see that the requests were going to the IPv6 loopback address and not the IPv4. I changed localhost to 127.0.0.1 and the issues were resolved. It's still a mystery to me as to why this would work after restarting Nginx but not before.
code :
  location / {
    proxy_pass http://127.0.0.1:3000;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_next_upstream error timeout http_502;

    # Basic auth
    auth_basic "Restricted";
    auth_basic_user_file /etc/nginx/htpasswd;
  }

hop of those help? Your question is a little confusing, because Services already live independently of Activities. Note, however, that Services run in the main thread by default. If you want to run the Service in a different thread (and in this case it looks like you do), you will have to set up a Messenger object and send messages between your worker thread and your UI thread. You can also look into using AIDL (on top of which Messenger is really built anyway). Your communication, if you don't use a Messenger, could use intents. If this is the case, you should look into IntentService. However, this only works when you are sending messages to the Service, not back and forth. If you want back and forth communication, you will have to use some sort of Messenger or similar pattern.
By the way, using an IntentService for things like 'stop' and 'start' is pretty common. Typically there is also a background thread, which communicates with the Service using a Messenger or something similar, and then sends / receives messages to instruct the worker thread as to what should be done.

I hope this helps you . I am using nginx as web server to my Django project. , You should go to
code :
cd /etc/init.d
vim nginx.conf
#Edit PATH , DAEMON variable
PATH=/usr/local/openresty/nginx/sbin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
DAEMON=/usr/local/openresty/nginx/sbin/nginx

fixed the issue. Will look into that further You can't allocate port 9010 of your host for both services. This is what you're doing in the ports section of declaration of service nginx and web.
Moreover, by default nginx will listen to port 80 and 443 for https.
code :
version: '3'

services:
  nginx:
    image: nginx:latest
    ports:
      - "10080:80"
      - "10443:443"
    volumes:
      - .:/app
      - ./config/nginx:/etc/nginx/conf.d
      - ./static_cdn:/static
   depends_on:
      - web

  web:
    build: .
    command: ./start.sh
    container_name: "web-app"
    volumes:
      - .:/app
      - ./static_cdn:/static
    expose:
      - "9010"
    depends_on:
      - db

  db: 
    image: postgres
upstream web {
  ip_hash;
  server web-app:9010;
}

server {
    location /static {
        autoindex on;
        alias /static/
     }

location / {
    proxy_pass http://web;
}

listen 80;
server_name localhost;
}

To fix this issue The difference between the examples you have provied is how the processes are being started.
Running the command nginx will start the application and wait for your user action to stop it.

seems to work fine If you’re compiling Nginx from source, you might be specifying the user and group flags at compile time.
If this is the case, you need to ensure that the users actually exist when you attempt to start Nginx.
