带有SSL的LEMP服务器上具有子域的WordPress多站点

Question

我正在尝试在LEMP堆栈（Ubuntu 18.04）中的服务器块上创建WordPress多站点（子域）。我跟随this guide使用其他具有域的服务器块来确保它们的安全。我对NGINX相当陌生，所以我不精通组合和徒手创建NGINX配置文件。

我设法创建了此配置文件，该文件使我可以查看主域，但没有子域。我需要更改什么才能使其正常工作？我非常感谢提前提供的有用建议！

    }

    location / {
    #try_files $uri $uri/ =404;
    try_files $uri $uri/ /index.php$is_args$args;
    }

    location ~ \.php$ {
            include snippets/fastcgi-php.conf;

            fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
    }

    location ~ /\.ht {
            deny all;
    }
    location ~ ^/files/(.*)$ {
            try_files /wp-content/blogs.dir/$blogid/$uri /wp-includes/ms-files.php?file=$1  ;
            access_log off; log_not_found off;      expires max;
    }

location ^~ /blogs.dir {
    internal;
    alias /var/www/example.com/htdocs/wp-content/blogs.dir;
    access_log off;     log_not_found off;      expires max;
}
}

当前，这是我的网站在正常的WP安装下可以找到我的其他工作WP服务器块的方式。
