Amazon Elastic Beanstalk上的Node.js部署问题

Question

I'm trying to deploy a node.js app using the Amazon Elastic Beanstalk service. Following this tutorial ( http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create_deploy_nodejs.sdlc.html ), I managed to deploy the app. However, once uploaded on Amazon, the application failed to start. Investigating the logs show me the following error : "Failed to run npm install".

Does anyone have a good idea of what the problem might be ? The application is working great locally.

Thanks in advance for your help!

Answer 1

I was having the same issue and Kevin's solution solved the problem for me, but introduced another: New instances spawned by EB for auto-scaling also need the manual configuration. This is the modification to Kevin's method that I made to solve both issues:

Another way to solve Kevin's issue is to add the required packages to a config file for your application. Create a configuration file with the extension .config (eg, myapp.config) and place it in an .ebextensions top-level directory of your source bundle. In order to require the openssl-devel package, include these lines in the config file:

packages:
    yum:
        openssl-devel: []

For details on where the config file goes: http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create_deploy_nodejs_custom_container.html

And details on including packages (and more) in the config file: http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/customize-containers-ec2.html

I found out what the problem was. Here is the explanation.

The reason why the npm package manager failed to install some packages was due to the fact that some packages required linux libraries to be install first (ie, OpenSSL-devel). In order to resolve this problem, I had to :

1. SSH to my EC2 instance associated with my Node.js Elastic Beanstalk instance

First, remove the "Termination Protection" on your EC2 instance (Click on your EC2 instance then look for "Change Termination Protection". Then, you need to add a "KeyPair" to the EC2 instance. For that, go to the ELB manager and edit the configuration file of your ELB application. For detailed explainations, check this link ( SSH to Elastic Beanstalk instance )

2. Install the missing libraries (in my case, because the bcrypt npm package was requiring it)

sudo yum update

sudo yum install openssl-devel

Hope this helps!

我遇到了这个问题，并通过简单地选择下一个更大的实例类型来解决它。

我发现了一个类似的问题，对我来说错误是因为一个节点包没有成功安装，所以当我从package.json中删除该节点包因为我真的不需要它，它工作了！
