In nginx under docker can not find files error.log and access.log-CodePudding

Installing nginx in docker from php:8.0.2-fpm I could not find error.log and access.log files, which I defined in nginx.conf :

server {
    listen 80;
    index index.php;
    error_log /var/log/nginx/error.log;
    access_log /var/log/nginx/access.log;
    error_page 404 /index.php;

    root /var/www/lar-nginx_docker_root/public;

    location ~ \.php$ {
        try_files $uri $uri/ =404;
        fastcgi_pass app:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

    location  / { # catch any non php files
        try_files $uri $uri/ /index.php?$query_string;
        gzip_static on;
    }

}

But entering in bash I can not opened these files and checking I do not see /var/log/nginx/ subdirectory:

master@master-laptop:/mnt/_work_sdb8/wwwroot/lar/lar-nginx/DOCKER$ docker-compose exec web bash
root@7f85f7225617:/var/www/lar-nginx_docker_root# cat /var/log/nginx/error.log

In DOCKER/docker-compose.yml I have :

    nginx:
        image: nginx:1.19-alpine
        container_name: lar_nginx_nginx
        # restart: always
        ports:
            - '8084:80'

        volumes:
            - ../:/var/www/lar-nginx_docker_root
            - ./nginx:/etc/nginx/conf.d

Is something is wrong in my configurations and how it can be fixed?

UPDATED BLOCK # 2 :

I fixed some invalid paths I had, but running

docker-compose up -d --build

with success I found some messages in nginx logs :

master@master-laptop:/mnt/_work_sdb8/wwwroot/lar/lar-nginx/DOCKER$ docker logs --tail=50  lar_nginx_nginx

nginx: [emerg] host not found in upstream "app" in /etc/nginx/conf.d/nginx.conf:12

and again no /var/log/nginx subdirectory :

master@master-laptop:/mnt/_work_sdb8/wwwroot/lar/lar-nginx/DOCKER$ docker-compose exec web bash

I have file virtualhost.conf :

<VirtualHost *:80>

  DocumentRoot /var/www/LAR-NGINX_docker_root/public
  <Directory /var/www/LAR-NGINX_docker_root/public>

  ErrorLog /var/log/nginx/error.log

  # Possible values include: debug, info, notice, warn, error, crit,
  # alert, emerg.
  LogLevel warn

</VirtualHost>

and in the end of my Dockerfile.yml I have :

  RUN  docker-php-ext-install gd pdo pdo_mysql pdo_sqlite zip gmp bcmath pcntl sysvmsg exif

  COPY virtualhost.conf /etc/nginx/conf.d/default.conf

  WORKDIR  /var/www/LAR-NGINX_docker_root

and in docker-compose.yml I added /var/log/nginx path :

version: '3.3'

        build:

        command: composer install  --ignore-platform-reqs

and I have working phpmyadmin by url :

http://127.0.0.1:8085/

But trying to open site

http://127.0.0.1:8084/

I got error :

This site can’t be reached
127.0.0.1 refused to connect.

What is wrong in my configurations ?

Thanks!

CodePudding user response：

Try to map your named volume onto your host:

 volumes:
      - logs:/var/log/nginx

And check if the access & error files are available!

CodePudding user response：

You check /var/log/nginx in lar_nginx_web rather than the nginx container which is lar_nginx_nginx. You see the logs when you run docker logs --tail=50 lar_nginx_nginx because you use the correct container name.

If you docker exec -it lar_nginx_nginx sh and ls -l /var/log/nginx you should see the log files.

Block 2

I don't think you need VirtualHost since it is for Apache, not Nginx.

You should use server block instead for Nginx config. Or if you're looking for php-fpm configuration then you should use php.ini/php-fpm.conf configuration
