如何将 nginx 反向代理修复为用户的 wordpress docker 重定向端口？

Question

所以我有一个我一直在试验的树莓派网络服务器，它运行 nginx 来服务多个站点等。我想在 docker 容器中作为博客运行 wordpress，但我在正确配置 nginx+docker wordpress 设置时遇到问题。

这是我的 docker-compose.yml：

version: "3"
services:
  db:
    image: hypriot/rpi-mysql
    restart: always
    volumes:
      - db_data:/var/lib/mysql
    environment:
      MYSQL_ROOT_PASSWORD: password
      MYSQL_DATABASE: wordpress
      MYSQL_USER: wordpress
      MYSQL_PASSWORD: <password>
    networks:
      - wp

  wordpress:
    depends_on:
      - db
    image: wordpress
    restart: always
    volumes:
      - ./:/var/www/html/wp-content
    environment:
      WORDPRESS_DB_HOST: db:3306
      WORDPRESS_DB_USER: wordpress
      WORDPRESS_DB_PASSWORD: <password>
    ports:
      - 8082:80
    networks:
      - wp

networks:
  wp:

volumes:
  db_data:

这是我当前的 nginx .conf for example.com：

server {
    client_max_body_size 32M;

    # Listen HTTP
    listen 80;
    server_name www.example.com example.com;

    # Redirect HTTP to HTTPS
    return 301 https://$host$request_uri;

}

server {
    client_max_body_size 32M;
    
    # Listen HTTP
    listen 443 ssl;

    server_name example.com www.example.com;

    # SSL config
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
   
    # does not fix the issue
    port_in_redirect off;

    # Proxy Config
    location / {

        # My attempts at fixing the port issue (did not work in any combination) 
        proxy_bind $host:443;
        proxy_redirect off;
        port_in_redirect off;
        absolute_redirect off;
        proxy_set_header Location $host:443;
        proxy_set_header Host $http_host:443;

        proxy_set_header X-Forwarded-Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass http://localhost:8082/;
    
        # an extra try despite my 8082 port not being open
        proxy_redirect https://example.com:8082/ https://example.com/;
    }

    # testing and looking at just the /wp-login.php "works" but without any of the content
    location ~ \.php {
        proxy_pass http://127.0.0.1:8082;
    }

}

我的问题：在访问我的 example.com 域时，我被重定向到 example.com:8082 并且没有获得任何内容，我在试图找出解决它的方法时遇到了很多问题。我也尝试过在端口 80 上使用 http，但这并没有什么不同（除非我在本地网络上，它在本地获取文件）

我在上面的 nginx 设置中缺少一个简单的东西吗？

有没有办法让 docker 在不同的虚拟端口上转发它？

好吧，看来问题不在于 docker/nginx 设置，而在于 wordpress。我在 [rpi.local.ip.address]:8082 上填写初始 wordpress 设置时犯了错误，这已保存在配置中。

我最终只是用docker-compose down --volumes 重置了卷，但这会删除你的所有数据。

真正的答案是这里发现的问题的解决方案： Docker: I can't map ports other than 80 to my WordPress container

我还对文件进行了一些修改，所以可以使用的文件如下：

如果这些都不适合你，那么你可以：

• 用docker-compose down --volumes重置容器，
• 删除ports: - 8082:80
• 转发到docker inspect [id-of-wordpress-container]和proxy_pass http://[docker-ip]:80/;找到的ip地址

然后设置wordpress安装，并且只有在重新添加ports: - 8082:80后才能重新启动后更改此ip

docker-compose.yml

services:
  db:
    image: mysql/mysql-server:8.0
    restart: always
    volumes:
      - db_data:/var/lib/mysql
    environment:
      MYSQL_ROOT_PASSWORD: password
      MYSQL_DATABASE: wordpress

/etx/nginx/sites-available/example.com.conf

如果 301 重定向被缓存在浏览器中，则会添加一个重定向

server {
    client_max_body_size 32M;

    # Listen HTTP
    listen 80;
    server_name www.example.com example.com;

    # Redirect HTTP to HTTPS
    return 301 https://$http_host$request_uri;

}

server {
    listen 8082 ssl;
    server_name example.com www.example.com;

    # SSL config
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;

    return 301 https://scienceangles.com;
}

server {
    client_max_body_size 32M;
    
    # Listen HTTP
    listen 443 ssl;
    
    server_name example.com www.example.com;

    # SSL config
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;

    ssl_stapling on;
    ssl_stapling_verify on;
   
    port_in_redirect off;

    # Proxy Config
    location / {
    proxy_pass http://localhost:8082;
    proxy_redirect off;
    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-Host $host;
    proxy_set_header X-Forwarded-Server $host;
    proxy_set_header X-Forwarded-Proto $scheme;
    
    }

}
