502坏网关NodeJS/MongoDB AWS Elastic Lectstalk

我正在运行502尝试在Elastic Beanstalk上运行NodeJS应用程序的Bad Gateway问题。我试图按照一个stackoverflow答案，告诉我要将我的起始脚本从server.js更改为main.js，但这并不奏效。我使用的是设置在.env文件中的env变量，它不是我git存储库的一部分，是否会导致此错误，还是因为启动脚本？502坏网关NodeJS/MongoDB AWS Elastic Lectstalk

我的配置仪表板中的这部分应该更改为我的开始文件吗？

enter image description here

这里是我的应用程序设置：

框架：Expressjs

数据库：MongoDB的

弹性魔豆服务器：64位Linux的亚马逊2014.09 V1.2.0运行Node.js的

我检查了我的日志，发现我的/var/log/nginx/error.log中没有任何内容，唯一的错误部分是coul d仅查找包含有关可能导致错误的信息。

{"status":"SUCCESS","api_version":"1.0","truncated":"false","results":[{"status":"SUCCESS","msg":"","returncode":0,"events":[{"msg":"No start scripts located in package.json. Node.js may have issues starting. Add start scripts or place code in a file named server.js or app.js.","severity":"ERROR","timestamp":1425234947517}]}]}

这里是我的package.json文件：

    "main": "main.js", 
    "dependencies": { 
    "body-parser": "1.6.5",

    "method-override": "~1.0.0", 
    "express-session": "~1.0.0", 
    "aws-sdk": "*" 
    } 
}

这里是我的main.js文件：

var router = express.Router(); // get an instance of the router 
var bodyParser = require('body-parser'); // configure app to use bodyParser()

var flash = require('connect-flash'); 
var morgan = require('morgan'); 
var cookieParser = require('cookie-parser'); 
var session = require('express-session'); 
var aws = require('aws-sdk'); 

app.use(bodyParser.urlencoded({ extended: true})); // get data from a POST method 
app.use(bodyParser.json()); 
app.use(morgan('dev')); 
app.use(cookieParser()); 


var port = process.env.PORT || 8080; // set the port 

var DB_CONFIG = process.env.DB_CONFIGURATION; 
var AWS_ACCESS_KEY = process.env.AWS_ACCESS_KEY; 
var AWS_SECRET_KEY = process.env.AWS_SECRET_KEY; 
var S3_BUCKET = process.env.S3_BUCKET; 

var blogDB = require('./config/blogDB.js'); 
mongoose.connect(blogDB.url); 




require('./config/passport.js')(passport); 


app.set('view engine', 'ejs'); // set ejs as the view engine 

app.use(express.static(__dirname + '/public')); // set the public directory 

app.use(session({ secret: 'thisisatest' })); 
app.use(passport.initialize()); 
app.use(passport.session()); 

app.use(flash()); 


var routes = require('./app/routes'); 

app.use(routes); // use routes.js 


app.listen(port); 
console.log('magic is happening on port' + port);

----------- UPDATE - -----------

我将env变量添加到Amazon配置仪表板中t将允许它看到连接到数据库和其他变量的位置。现在我收到一个错误日志：

会发生什么事，当你运行npm start本地？错误消息表示您尚未指定启动脚本。 AWS可能使用npm start启动您的服务器，并且该命令似乎失败。

尝试增加了此信息的package.json：

"scripts" : { 
    "start" : "node main.js" 
}

感谢您的回应。当我尝试在本地运行'npm start'时，我只是在终端中发送一个空行。基本上没有任何反应。我假设这看起来像命令失败一样。我将脚本添加到我的package.json中，但没有任何更改。任何其他提示？也许与'npm start'这个事实有关的事情什么都不做？ – cphill 2015-03-04 00:27:37

这可能是因为服务器无法访问我的env变量？当我运行'node main.js'时，会出现一个与不访问mongoDB有关的错误。这听起来是正确的，因为访问连接到一个env变量。我将我的env变量添加到了Elastic Beanstalk配置文件，但我得到了相同的502响应 – cphill 2015-03-04 17:24:40

实际上，现在我已经在配置仪表板中设置了env变量，我终于收到一个错误日志。请参阅编辑的问题以获取错误日志。不知道如何理解这些信息。 – cphill 2015-03-04 17:30:46

固定！我所要做的只是进入配置>容器选项并设置节点命令为node main.js
