'default public web root'可以在nginx -V output中找到:

前缀值是问题的答案。对于上面的示例，根目录是/var/lib/nginx

*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 {
        root /media/odroid/;
        autoindex on;

    }

        # This option is important for using PHP.
    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/var/run/php/php7.1-fpm.sock;
    }
}

*默认配置服务器etc/nginx/nginx.conf

IP客户端的默认访问日志var/log/nginx/…

Debian上Nginx的默认目录是/var/www/nginx-default。

可以查看“/etc/nginx/sites-enabled/default”文件

并找到

server {
        listen   80 default;
        server_name  localhost;

        access_log  /var/log/nginx/localhost.access.log;

        location / {
                root   /var/www/nginx-default;
                index  index.html index.htm;
        }

根节点是默认位置。

需要注意的是，nginx服务器的默认索引页面也会显示根位置。从Amazon Linux AMI上的nginx(1.4.3)，您可以得到以下内容:

这是默认的index.html页面，在Amazon Linux AMI上与nginx一起分发。它位于/usr/share/nginx/html。

你现在应该把你的内容放在你选择的位置，并编辑nginx配置文件/etc/nginx/nginx.conf中的根配置指令

如果你需要找到编译时定义的nginx公共根文件夹，你可以检查你的access.log文件。

打开nginx.conf 找到log_format指令 log_format的值是一个模板字符串，用于将信息写入access.log文件。您可以在这个模板字符串中添加$document_root变量，以将默认的www根位置记录到文件中。

下面是来自nginx.conf的http部分的一个例子，修改了log_format指令，$document_root被添加在字符串的开头:

    http {
        include       /etc/nginx/mime.types;
        default_type  application/octet-stream;

                  ## ADD $document_root HERE ##
        log_format  main  '$document_root $remote_addr - $remote_user [$time_local] "$request" '
                          '$status $body_bytes_sent "$http_referer" '
                          '"$http_user_agent" "$http_x_forwarded_for"';

        access_log  /var/log/nginx/access.log  main;

        etc. .......

然后备份conf.d目录下的所有配置文件*.conf，并创建配置文件test.conf，如下所示: 服务器{ 听80; server_name主机; ｝ 在“/etc/hosts”文件中增加如下一行:127.0.0.1 localhost 重载nginx配置:nginx -s重载 发送GET请求到http://localhost: curl http://localhost 查看access.log的最后一个字符串:tail -n 1 /var/log/nginx/access.log

下面是该命令的输出示例，其中/etc/nginx/html是编译时定义的默认文档根:

    /etc/nginx/html 127.0.0.1 - - [15/Mar/2017:17:12:25 +0200] "GET / HTTP/1.1" 404 169 "-" "curl/7.35.0" "-"

对于AWS EC2 Linux，您将在这里找到:

/usr/share/nginx
