Nginx 非 www 无法在 Ubuntu 16.04 中工作和重定向

Question

我的服务器在 DO 中运行在 Ubuntu 16.04 中。 我的问题是，当我尝试在没有 www 的情况下运行时，我的网站无法加载。

我从这里开始学习教程。 https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-16-04

我的目标是

1. 将所有非www重定向到https://example.com
2. 将所有www重定向到https://www.example.com

nginx/sites-available/nginx_config

server {
    listen 80;
    server_name example.com http://example.com;
    return 301 https://example.com$request_uri;
}
server {
        listen 80;
        server_name www.example.com http://www.example.com;
        return 301 https://www.example.com$request_uri;
}
server {
        listen 443 ssl http2 default_server;
        listen [::]:443 ssl http2 default_server;
        include snippets/ssl-example.com.conf;
        include snippets/ssl-params.conf;
        root /home/tim/site.folder;
        index index.html index.htm index.nginx-debian.html;
        server_name _;
        location ~ /.well-known {
            allow all;
        }
        location / {
            try_files $uri $uri/ =404;
        }
}

到目前为止我所尝试的：

删除 第一个和第二个服务器块中的 http。 （在第二个服务器块中相同）

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

Answer 1

实现你的目标
1.将所有非www重定向到https://example.com 2.将所有www重定向到https://www.example.com 这可以通过

server_name www.example.com example.com;

你可以像下面这样使用完整的配置

server {
  listen 80;
  server_name www.example.com example.com;
  access_log off;
  index index.html index.htm index.php;
  listen 443 ssl http2 default_server;
  listen [::]:443 ssl http2 default_server;
  include snippets/ssl-example.com.conf;
  include snippets/ssl-params.conf;
  root /home/tim/site.folder;

location ~ [^/]\.php(/|$) {
 #fastcgi_pass remote_php_ip:9000;
 fastcgi_pass unix:/dev/shm/php-cgi.sock;
 fastcgi_index index.php;
 include fastcgi.conf;
}
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|flv|ico)$ {
 expires 30d;
 access_log off;
}
location ~ .*\.(js|css)?$ {
 expires 7d;
 access_log off;
}
}

Answer 2

不要放http

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

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

 server {
    listen 443 ssl http2 default_server;
    listen [::]:443 ssl http2 default_server;
    server_name example.com www.example.com;
    include snippets/ssl-example.com.conf;
    include snippets/ssl-params.conf;
    root /home/tim/site.folder;
    index index.html index.htm index.nginx-debian.html;

    location ~ /.well-known {
        allow all;
    }
    location / {
        try_files $uri $uri/ =404;
    }
 }
