NGINX配置不将非www重定向到www

Question

我在AWS EC2实例上托管的Ubuntu 16服务器上的端口3000上运行了NodeJS应用程序。我希望NGINX将以下每个地址重定向到https://www.example.com：

1. http://example.com
2. http://www.example.com
3. https://example.com

为此，我已将/etc/nginx/sites-available/default文件配置如下：

server {
    listen 80;
    listen [::]:80;
    server_name example.com;
    location / {
        # Redirect any http requests to https
        return 301 https://www.$server_name$request_uri;
     }
     location ~* \.(?:ico|svg|woff|woff2|ttf|otf|css|js|gif|jpe?g|png)$ {
        proxy_pass http://127.0.0.1:3000;
        expires 30d;
        add_header Pragma public;
        add_header Cache-Control "public";
     }
}

# Settings for a TLS enabled server
server {
        listen 443 ssl http2;
        listen [::]:443 ssl;
        server_name  www.example.com;

        ssl_certificate "/etc/letsencrypt/live/example.com/fullchain.pem";
        ssl_certificate_key "/etc/letsencrypt/live/example.com/privkey.pem";

        # Automatically route HTTP to HTTPS
        add_header Strict-Transport-Security "max-age=31536000";

        include /etc/nginx/default.d/*.conf;

        location / {
            proxy_pass http://127.0.0.1:3000;
       }
   }

但是，这似乎只是部分工作：

1. http://example.com - >去https://example.com而不是https://www.example.com
2. http://www.example.com - >去https://example.com而不是https://www.example.com
3. https://example.com - >去https://example.com而不是https://www.example.com
4. https://www.example.com - >工作正常

有什么建议？

对于要重定向的每个案例，您应该有一个服务器块：

server {
  listen 80;
  listen [::]:80;
  server_name example.com;
  return 301 https://www.example.com$request_uri;
}
server {
  listen 80;
  listen [::]:80;
  server_name www.example.com;
  return 301 https://www.example.com$request_uri;
}

# Settings for a TLS enabled server
server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    server_name  example.com;
    return 301 https://www.example.com$request_uri;
}
server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    server_name  www.example.com;

    ssl_certificate "/etc/letsencrypt/live/example.com/fullchain.pem";
    ssl_certificate_key "/etc/letsencrypt/live/example.com/privkey.pem";

    # Automatically route HTTP to HTTPS
    add_header Strict-Transport-Security "max-age=31536000";

    include /etc/nginx/default.d/*.conf;

    location / {
        proxy_pass http://127.0.0.1:3000;
   }
}
