在64位AmazonLinux2/3.4.4上运行的AWS弹性豆柄-Ruby3.0- 100.0 %的请求在HTTP5xx中失败

Question

今天，对我们所有人来说，又是一个令人惊奇的日子:)

我试图使用运行在64位Amazon 2/3.4.4上的AWS EB Ruby3.0和Rails v6.0.4.4应用程序，但直到现在，我还没有设法使它工作。

在env状态下，我得到：

100.0 % of the requests are failing with HTTP 5xx

也在/var/log/nginx/error.log中

[error] 2459#2459: *596 connect() to unix:///var/run/puma/my_app.sock failed (11: Resource temporarily unavailable) while connecting to upstream, client: 172.31.34.113, server: _, request: "POST / HTTP/1.1", upstream: "http://unix:///var/run/puma/my_app.sock:/", host: "52.29.66.93"

以及在/var/log/puma/puma.log中

[4898] ! Unable to start worker
[4898] /opt/rubies/ruby-3.0.3/lib/ruby/site_ruby/3.0.0/bundler/runtime.rb:309:in `check_for_activated_spec!'
[4898] Early termination of worker

pumactl看上去还行

[ec2-user@ip-172-31-xx-xx ~]$ pumactl -V
5.6.2

如果我检查这些过程：

ps aux | grep puma
    healthd  25925  0.0  3.6 828800 36624 ?        Ssl  09:39   0:15 puma 5.3.2 (tcp://127.0.0.1:22221) [healthd]
    webapp   26497  0.2  2.2 255768 22912 ?        Ss   09:40   1:07 puma 5.6.2 (unix:///var/run/puma/my_app.sock) [current]

所以美洲狮跑了..。对，是这样?

另外，还有另一只美洲狮5.3.2

也许这另一个美洲豹版本是出于另一个原因(卫生服务)？

在Rails应用程序中，我有以下内容：

container_commands:
  01_restart_nginx:
    command: "sudo service nginx reload"

你知道它为什么不起作用吗？

在.ebextensions/03_nginx.config中，files部分中有一个/etc/nginx/conf.d/02_app_server.conf条目，但是没有这样的文件：

ls -ls /etc/nginx/conf.d/
total 8
0 drwxr-xr-x 2 root root  45 Apr  8 15:42 elasticbeanstalk
4 -rw-r--r-- 1 root root  62 Apr  8 15:42 elasticbeanstalk-nginx-ruby-upstream.conf
4 -rw-r--r-- 1 root root 147 Apr  8 15:42 healthd_logformat.conf

这样可以吗？

非常感谢您的帮助和支持，感谢您宝贵的时间。

我祝愿我们所有的人在我们的生活中一切顺利和令人惊奇.

由于您使用的是Amazon Linux 2，您的nginx设置将永远无法工作。这是因为它们是用于AL1的，但是您使用的是AL2。所有的nginx设置都应该通过.platform/nginx/conf.d/来定义，而不是像文档中解释的那样定义.ebextentions。
