Question

为什么我的此网站无法访问这个页面，但我的终端上似乎没有错误？

当我通过 IP地址访问服务器时，没关系：

但是使用域名，我明白了：

$ sudo systemctl status nginx

这似乎是错误：

*6 open() "/usr/share/nginx/html/favicon.ico" failed (2: No such file or directory), client: 183.171

这是什么意思？它与域名无关！

这是我配置的一部分：

server {
    listen 80;
    server_name example.co.uk www.example.co.uk;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }
}

server {
    listen 443 ssl;
    server_name  example.co.uk www.example.co.uk;

    ssl_certificate /etc/letsencrypt/live/example.co.uk/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/example.co.uk/privkey.pem;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

    location ~ /.well-known {
            allow all;
    }
}

server {
    listen 8888 ssl;
    server_name  example.co.uk www.example.co.uk;

    ssl_certificate /etc/letsencrypt/live/example.co.uk/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/example.co.uk/privkey.pem;

    location ~ /.well-known {
        allow all;
    }

    location / {
            proxy_set_header   X-Real-IP $remote_addr;
            proxy_set_header   Host      $http_host;
            proxy_pass         http://127.0.0.1:3838;
    }

}

测试代码：

$ sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

之前一切正常，但现在却突然停了下来。

有什么想法吗？

我按照guide在我的Arch Linux上安装Nginx btw。

我采取的步骤：

$ sudo pacman -Syu
$ sudo pacman -S nginx

启动Nginx服务并使用命令启用它以启动启动：

$ sudo systemctl start nginx
$ sudo systemctl enable nginx

修改

我现在已经卸载了Ngnix并重新安装了它，但即使在没有任何配置/etc/nginx/nginx.conf的情况下重新启动它也不再有效。我得到的是浏览器无法访问此网站。

为什么！??

我使用netstat进行了检查，我可以看到端口80位于列表中：

$ sudo netstat -tulpn

编辑2：

我创建了一个访问日志。但我没有看到任何重大错误：

$ more -f /etc/nginx/logs/access.log

Answer 1

从Nginx访问日志中查找正在发生的事情！在检查之前，请确保您已记录足够的数据。您可以使用以下log_format。

log_format main '$host - $remote_addr - $remote_user - [$time_local] - $document_root - $document_uri - $request - $status - $body_bytes_sent - $http_referer';

重新启动您的Nginx服务并提出一些请求。您需要确定请求是否甚至到达服务器。访问日志应该能够清楚地显示正在进行的操作。

Answer 2

由于您没有dns服务器，因此要向具有指定域名的服务器发送请求，您需要在/ etc / hosts中添加一个条目（此路径取决于您的本地计算机系统）客户端计算机的文件。您需要在该文件中添加以下行，就像这样：

sudo nano /private/etc/hosts

...并且：

# The client /etc/hosts file

<ip-of-your-server>   www.yourdomainname.com

Nginx不能在域名上工作但在IP地址上可以正常工作吗？
