带有 AWS Elastic Beanstalk 问题的瘦服务器
Thin server with AWS Elastic Beanstalk issue
我正在尝试将使用瘦服务器的 Sinatra 应用程序从 Heroku 迁移到 AWS Elastic Beanstalk。目前的问题是 Nginx 正在寻找 Puma 服务器而不是 Thin:
connect() to unix:///var/run/puma/my_app.sock failed (2: No such file or directory)
是否可以使用 Thin AWS Elastic Beanstalk？
我能够使用以下文件在 AWS Elastic Beanstalk 上获得瘦服务器 运行。关闭 Puma 服务器尚未生效。

除了@user2666194的精彩回答外，我发现EB会抱怨由于应用程序不是运行而处于降级状态运行。
似乎 healthd 检查 /var/elasticbeanstalk/healthd/application.pid 中列出的 pid 以确保应用程序是 运行。默认情况下链接到 /var/run/puma/puma.pid.
为了解决这个问题，我修改了 01_nginx.config 文件以删除并替换此 pid。我还添加了 initctl 命令来停止 puma。现在我们正在检查正确的 pid，这似乎没有不良影响：
