I want to migrate my NodeJS project from single EC2 to ElasticBeanstalk. In my current code I use the dependency log4js which create a log file on the filesystem. On EC2 this works create but what is the best way in ElasticBeanstalk to log something? If I download the generated logs from ElasticBeanstalk my custom log file from log4js isn't present.
我想将我的NodeJS项目从单个EC2迁移到ElasticBeanstalk。在我当前的代码中，我使用依赖log4js，它在文件系统上创建一个日志文件。在EC2上，这可以创建但是ElasticBeanstalk中记录内容的最佳方法是什么？如果我从ElasticBeanstalk下载生成的日志，则log4js中的自定义日志文件不存在。
Best regards

In order to see the logs you can:
要查看日志，您可以：
- Press on your elastic beanstalk environment
- 按下弹性beanstalk环境
- Press 'Logs' (on the left side)
- 按“日志”（在左侧）
- Press 'Request Logs' (usually just last 100 lines should be fine) and download the file.
- 按“请求日志”（通常只有最后100行应该没问题）并下载文件。
You can see a few different log files there.
您可以在那里看到一些不同的日志文件。
I believe that logs you write using log4js in Node.js will be under:
我相信你在Node.js中用log4js写的日志将在：
/var/log/nodejs/nodejs.log
/var/log/nodejs/nodejs.log
I like to ssh into the elastic beanstalk instance and tail the log to see it updating "live" (when I use my server). to do it run the following:
我喜欢ssh进入弹性beanstalk实例并拖尾日志，看它更新“live”（当我使用我的服务器时）。要做到这一点运行以下：
eb ssh
eb ssh
tail -n 50 -f /var/log/nodejs/nodejs.log
tail -n 50 -f /var/log/nodejs/nodejs.log
In general, when you deploy to Elastic Beanstalk linux environment your app will be under:
通常，当您部署到Elastic Beanstalk linux环境时，您的应用程序将位于：
/var/app/current
在/ var /应用/电流
Try finding your log files under this path- they will have the same name as when you run the app locally.
尝试在此路径下查找日志文件 - 它们与您在本地运行应用程序时的名称相同。
