Node JS 应用程序在 AWS EC2 实例上崩溃 [英] Node JS app is crashing on AWS EC2 instance

问题描述

我已使用 codedeploy 服务在 ec2 上部署应用程序，但应用程序崩溃并显示以下错误消息:

I have deployed app on ec2 using codedeploy service but app is crashing and showing below error message:

Script at specified location: scripts/start_server failed to complete in 100 seconds

以下是我的 appspec.yml 文件:

version: 0.0
os: linux
files:
  - source: /
    destination: /tmp/
hooks:
  AfterInstall:
     - location: scripts/install_dependencies
       timeout: 100
       runas: root
  ApplicationStart:
     - location: scripts/start_server
       timeout: 100
       runas: root

install_dependencies

cd /tmp/

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash
. ~/.nvm/nvm.sh
nvm install node

npm install

start_server

cd /tmp/

node server.js

有人告诉我我做错了什么.

Someone let me know what I am doing wrong.

推荐答案

你的部署因为这个 node server.js 挂起.这将启动您的应用程序，仅此而已.它永远不会完成，因此 CodeDeploy 超时等待它完成.

Your deployment hangs because of this node server.js. This will start your app and that's it. It will never finish, so CodeDeploy timeouts waiting for that to finish.

解决该问题的一种方法是通过 systemd 启动您的应用.因此，您必须创建一个 systemd 单元文件.有很多例子:

One way to overcome the problem is to start your app through systemd. Thus you have to create a systemd unit file. There are many examples for that:

• 运行您的 Node.js 应用使用 Systemd
• 使用 systemd 在 Linux 上运行 Node.js

其他方式可能涉及使用 pm2 或 永远.

Other ways could involve running your app using pm2 or forever.
