ubuntu nginx 虚拟主机问题未重定向到所需文件夹

Question

我已向 ubuntu droplets 添加了 2 个域。 a.com 和 b.com。两个 A 记录都重定向到 IP。

我还为这两个域创建了虚拟主机。喜欢

server {
        listen 80;
        listen [::]:80;

        root /var/www/html/b.com;

        # Add index.php to the list if you are using PHP
        index index.html index.htm index.php index.nginx-debian.html;

        server_name b.com www.b.com;

        location / {
                 try_files $uri $uri/ /index.php$is_args$args;
        }


        location ~ \.php$ {
                include snippets/fastcgi-php.conf;
                fastcgi_pass unix:/run/php/php7.0-fpm.sock;
        }
}

但是 b.com 没有重定向到期望文件夹。当我从 url 访问域时。它重定向到主 IP 文件夹，如 /var/www/html 而不是 /var/www/html/b.com

我的默认虚拟主机

server {
        listen 80;
        listen [::]:80;

        root /var/www/html/;

        # Add index.php to the list if you are using PHP
        index index.html index.htm index.php index.nginx-debian.html;

        server_name _;

        location / {
                 try_files $uri $uri/ /index.php$is_args$args;
        }


        location ~ \.php$ {
                include snippets/fastcgi-php.conf;
                fastcgi_pass unix:/run/php/php7.0-fpm.sock;
        }
}

我按照这些说明操作但仍然无法正常工作：https://www.digitalocean.com/community/tutorials/how-to-set-up-nginx-server-blocks-virtual-hosts-on-ubuntu-16-04

Answer 1

server_name _;

是一个包罗万象的服务器，如果它首先出现在您的配置中，它将首先被提供。您可以在此处阅读更多相关信息：http://nginx.org/en/docs/http/server_names.html

如果你改成

server_name a.com www.a.com;

它应该适合你。 我建议你阅读这部分文档：http://nginx.org/en/docs/http/request_processing.html

完整配置：

server {
    listen 80;

    server_name b.com www.b.com;

    root /var/www/html/b.com/;

    # Add index.php to the list if you are using PHP
    index index.html index.htm index.php index.nginx-debian.html;

    location / {
             try_files $uri /index.php?$args;
    }


    location ~ \.php$ {
            try_files $uri =404;
            include /etc/nginx/fastcgi_params;
            include snippets/fastcgi-php.conf;
            fastcgi_pass unix:/run/php/php7.0-fpm.sock;
            fastcgi_index   index.php;

            fastcgi_buffer_size 128k;
            fastcgi_buffers 256 16k;
            fastcgi_busy_buffers_size 256k;
            fastcgi_temp_file_write_size 256k;
    }
}
