运行OpenShift节点服务器:获取错误Application 'appname'启动失败(8080端

Running an OpenShift node server: Getting error Application 'appname' failed to start (port 8080 not available)

本文关键字：启动 appname 失败 8080 OpenShift 节点 获取 取错误 Application 运行 服务器      更新时间：2023-09-26

我正在尝试为我正在开发的游戏运行服务器。当我运行$git push时，我得到了错误Application 'appname' failed to start (port 8080 not available)。(我之前运行过git add和git commit)。这是我的服务器代码:' 

//Lets require/import the HTTP module
var http = require('http');
//var fs = require("fs");
//var index = fs.readFileSync('test.txt');
//Lets define a port we want to listen to
const PORT=8081; 
//We need a function which handles requests and send response
function handleRequest(request, response){
    response.end("hi");
}
//Create a server
var server = http.createServer(handleRequest);
//Lets start our server
server.listen(PORT, "127.0.0.1",function(){
    //Callback triggered when server is successfully listening.
    console.log("Server listening on: http://localhost:%s", PORT);
});

根据我所做的研究，如果你的代码中有错误，你会得到端口不可用错误，但我已经测试了在我的计算机上本地运行应用程序，它运行得很好(我能够连接，我看到消息"hi")。我注释掉文件系统(fs)的原因是因为我想测试问题是否是因为OpenShift应用程序没有安装fs(它不是)。我也尝试运行一个完全空的服务器，但我仍然得到同样的错误。因此，我认为问题不在于丢失了什么包裹。我已经检查了8080端口上是否已经有东西在运行，但是我没有看到任何东西。

错误日志:

warning: push.default is unset; its implicit value has changed in
Git 2.0 from 'matching' to 'simple'. To squelch this message
and maintain the traditional behavior, use:
  git config --global push.default matching
To squelch this message and adopt the new behavior now, use:
  git config --global push.default simple
When push.default is set to 'matching', git will push local branches
to the remote branches that already exist with the same name.
Since Git 2.0, Git defaults to the more conservative 'simple'
behavior, which only pushes the current branch to the corresponding
remote branch that 'git pull' uses to update the current branch.
See 'git help config' and search for 'push.default' for further information.
(the 'simple' mode was introduced in Git 1.7.11. Use the similar mode
'current' instead of 'simple' if you sometimes use older versions of Git)

我真的不关心审查任何信息，我希望没有人因为错误日志而窃取任何东西，如果这个问题很长，很抱歉…也很抱歉，如果这听起来很无聊，我昨天开始使用OpenShift和GitHub。如果你有任何问题或想要一些其他信息，请评论!我将非常感谢任何帮助我可以得到!:)

标准的Openshift Node.js磁带提供了您应该使用环境变量侦听的端口和IP。

我会使用这样的东西，因为PORT和IP是更常见的方法，如果没有提供(开发环境)，它会像现在一样听:

const PORT = process.env.OPENSHIFT_NODEJS_PORT ||process.env.PORT || 8080;
const IP = process.env.OPENSHIFT_NODEJS_IP || process.env.IP || '0.0.0.0';
