NGINX配置不会将非www重定向到www

Question

我有一个NodeJS应用程序运行在AWS EC2实例上托管的Ubuntu 16服务器上的端口3000上。我希望NGINX将以下每个地址重定向到http://example.com：

1. http://www.example.com
2. https://example.com
3. /etc/nginx/sites-available/default

为此，我将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; } } 文件配置如下：

http://example.com

但是，这似乎只能部分起作用：

1. https://example.com ->转到 https://www.example.com ，而不是 http://www.example.com
2. https://example.com ->转到 https://www.example.com ，而不是 https://example.com
3. https://example.com ->转到 https://www.example.com ，而不是 https://www.example.com
4. {{1}} ->运行正常

有什么建议吗？

对于每种要重定向的情况，您都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;
   }
}
