需求场景

如果需要实现demo演示站。当然不希望每个小项目都去配置域名解析，太麻烦。所以用到了域名泛解析。并且将域名前缀和目录名字对应，根据目录名字即可访问对应的域名，就减少了很多配置。

具体配置(php示例)

server {
    listen 80;
    server_name ~^(?<subdomain>.+).demo.urcloud.co$;
    root /home/demos/$subdomain;
    index index.html index.htm index.php;
    fastcgi_intercept_errors on;
    error_page 404 = /404.html;
    location / {
        # This is cool because no php is touched for static content.
        # include the "?$args" part so non-default permalinks doesn't
        # break when using query string
        try_files $uri $uri/ =404;
    }

    # redirect server error pages to the static page /50x.html
    #
    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
        root html;
    }

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ .*\.php(\/.*)*$ {
        fastcgi_pass unix:/run/php/php7.2-fpm.sock;
        include fastcgi.conf;
    }

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    location ~ /.ht {
        deny all;
    }
}
