如果你是通过homebrew安装的，并且你使用的是macOS，你可以在/opt/homebrew/Cellar/nginx/1.23.2/html找到它，用你的版本替换1.23.2。

默认值与nginx编译时configure脚本的prefix选项有关;下面是一些来自Debian的奇怪的例子:

% nginx -V | & tr ' ' "\n" | fgrep -e path -e prefix
--prefix=/etc/nginx
--conf-path=/etc/nginx/nginx.conf
--error-log-path=/var/log/nginx/error.log
--http-client-body-temp-path=/var/lib/nginx/body
--http-fastcgi-temp-path=/var/lib/nginx/fastcgi
--http-log-path=/var/log/nginx/access.log
--http-proxy-temp-path=/var/lib/nginx/proxy
--http-scgi-temp-path=/var/lib/nginx/scgi
--http-uwsgi-temp-path=/var/lib/nginx/uwsgi
--lock-path=/var/lock/nginx.lock
--pid-path=/var/run/nginx.pid

随后，root的默认值被设置为html目录(根据root指令的文档)，它恰好在prefix中，可以通过查看简单配置文件中的$document_root变量来验证:

# printf 'server{listen 4867;return 200 $document_root\\n;}\n' \
    >/etc/nginx/conf.d/so.10674867.conf

# nginx -s reload && curl localhost:4867
/etc/nginx/html

然而，像Debian这样的邪恶发行版似乎对它进行了相当大的修改，以让你获得额外的娱乐:

% fgrep -e root -e include /etc/nginx/nginx.conf
    include /etc/nginx/mime.types;
    #include /etc/nginx/naxsi_core.rules;
    #passenger_root /usr;
    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;

% fgrep -e root -e include \
    /etc/nginx/conf.d/*.conf /etc/nginx/sites-enabled/*
/etc/nginx/conf.d/so.10674867.conf:server{listen 4867;return 200 $document_root\n;}
/etc/nginx/sites-enabled/default:   root /usr/share/nginx/www;
/etc/nginx/sites-enabled/default:       # include /etc/nginx/naxsi.rules
/etc/nginx/sites-enabled/default:   #   root /usr/share/nginx/www;
/etc/nginx/sites-enabled/default:   #   include fastcgi_params;
/etc/nginx/sites-enabled/default:   # deny access to .htaccess files, if Apache's document root
/etc/nginx/sites-enabled/default:#  root html;
/etc/nginx/sites-enabled/default:#  root html;

所以，在这个Debian实例中，你可以看到根目录最终被设置为/usr/share/nginx/www.

但是，正如您在示例服务器配置中看到的，它将通过http提供$document_root值，配置nginx非常简单，您可以在一两行代码内编写自己的配置，指定所需的根以满足您的确切需求。

对于AWS EC2 Linux，您将在这里找到:

/usr/share/nginx

查看nginx配置文件来确定。 这个命令是greps在你的机器上配置的任何东西:

cat /etc/nginx/sites-enabled/default |grep "root"

在我的机器上，它是:root /usr/share/nginx/www;

你可以访问nginx文件配置，你可以看到root /path。在这个 nginx apache的默认地址是/var/www/html

*默认页面web分配在var/www/html *默认配置服务器etc/nginx/sites/ available /nginx.conf

server {

    listen 80 default_server;
    listen [::]:80 default_server;

    root /var/www/html;

    index index.html index.php;

    server_name _;

    location /data/ {
        autoindex on;
    }

    location /Maxtor {

        autoindex on;

    }

        # This option is important for using PHP.

        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/var/run/php/php7.1-fpm.sock;
    }
}
