Node.js一直给出503错误 [英] Node.js consistently giving 503 error

问题描述

我刚刚安装了Node.js，让它工作了一段时间，然后尝试运行标准的Hello World程序。

I just installed Node.js, got it working for a while, then tried to run a standard Hello World program.

var http = require("http");

http.createServer(function (request, response) {

   // Send the HTTP header
   // HTTP Status: 200 : OK
   // Content Type: text/plain
   response.writeHead(200, {'Content-Type': 'text/plain'});

   // Send the response body as "Hello World"
   response.end('Hello World\n');
}).listen(8081);

// Console will print the message
console.log('Server running at http://127.0.0.1:8081/');

然后我启动了我为节点设置的域， http://node.foobar.com - 我成功打印 Hello World 当我做了上周在我的域名上也一样。但是现在，我一直收到 503服务暂时不可用错误。

I then launched the domain I set up for node, http://node.foobar.com - I successfully got it to print Hello World when I did the same on my domain last week. However now, I keep getting 503 Service Temporarily Unavailable error.

这也发生在上周，我关闭了服务器，编辑代码，然后重新启动服务器，它将503，除非我等待几分钟再运行。但是，这次等待没有任何区别。

This happened last week too, after I closed the server, edited the code, then reran the server, it would 503 unless I waited a few minutes before running again. However, waiting makes no difference this time.

域名的Apache配置：

Apache config for domain:

<VirtualHost *:80>
ServerAdmin zadmin@localhost
DocumentRoot "/var/zpanel/hostdata/zadmin/public_html/node"
ServerName node.foobar.com

ProxyRequests on
ProxyPass / http://localhost:3102/

# Custom settings are loaded below this line (if any exist)
</VirtualHost>

推荐答案

如何设置域名？

您是否使用其他HTTP服务器作为代理？

Did you use another HTTP server as a proxy?

请检查节点是否正在运行，如果是，请检查您的HTTP服务器也是。

Please check if node is running, and if yes check your HTTP server is too.

可能你的节点崩溃或者没有运行。

Maybe your node crashed or is just not running.

另一项测试是连接你的节点直接：

Another test is to connect your node directly:

http://127.0.0.1:8081/
