打开移动节点+ mongodb无法启动

Question

我试图部署一个节点6.0服务器与mongo 3.2到openshift。 我已经成功地创建使用节点DIY盒的应用，因为在这里找到：http://cartreflect-claytondev.rhcloud.com/reflect?github=connyay/openshift-node-diy

，并给它添加一个蒙戈DIY盒以及：https://raw.githubusercontent.com/icflorescu/openshift-cartridge-mongodb/master/metadata/manifest.yml

此外，我已经添加.Openshift \ action_hooks文件它将npm install作为构建脚本的一部分。

现在到了怪异的部分，在推送更改和依赖项完成安装后，我得到正常消息说部署成功。但是，当我尝试访问它时，服务器不断返回503错误。我试图RHC尾打电话追查出了什么服务器启动过程中错误的，但我得到的是这样的日志从MongoDB的：

其次是这个错误日志（由节点抛出显然，虽然找不到一个文件：

我失去了什么这里有不似乎这里是任何真正的错误消息，它只是说，我的scripts.start脚本失败，有些建议可能是一些与环境变量，但林不？。完全可以确定哪个可能会把事情搞得像这样

编辑

我还要提到的是我已经把我的WWW应用程序设置为使用时可用的openshift变量：

var port = normalizePort(process.env.OPENSHIFT_NODEDIY_PORT || '3000'); 
app.set('port', port); 

var ip = process.env.OPENSHIFT_NODEDIY_IP || localhost; //'192.168.1.16' 
app.set('ip', ip); 

和蒙戈连接：

var mongodb_connection_string = 'mongodb://localhost/' + db_name; 
    //take advantage of openshift env vars when available: 
    if(process.env.MONGODB_URL){ 
     mongodb_connection_string = process.env.MONGODB_URL + db_name; 
    } 

编辑2 我最终设法找到存储我得到的节点错误的日志文件，似乎rhc尾巴没有返回l堆栈，但只有最后几行。整个日志实际上揭示了有关该问题的更多细节（请参阅上面编辑的错误）

Answer 1

所以我终于明白出了什么问题。

看来，（目前webstorm）通过我的IDE创建的默认节点项目被配置为监听端口，无论上的IP，所以我的WWW脚本有这样的：

var port = normalizePort(process.env.OPENSHIFT_NODEDIY_PORT || '3000'); 
app.set('port', port); 

var ip = process.env.OPENSHIFT_NODEDIY_IP || localhost; 
app.set('ip', ip); 

/** 
* Create HTTP server. 
*/ 

var server = http.createServer(app); 

/** 
* Listen on provided port, on all network interfaces. 
*/ 

server.listen(port); 

所以最后一行你看我只听端口，忽略IP，将最后一行改为

server.listen(port, ip); 

修复了这个问题。
