Ruby on rails Elastic Beanstalk Redis失败，Webapp无响应

无法通过sidekiq错误

正在尝试从Heroku迁移到AWS EB。我有一个在linux机器上运行rails 4.2.0和ruby 2.3的rails应用程序，但一直遇到问题。webapp不会加载-它只是一次又一次地超时

Redis一直告诉我它的

url为零

，尽管它的设置似乎很可靠。（它可以在另一个应用程序上运行，我设法使用相同的配置运行。我还发现错误错误通知也很麻烦，但Redis URL甚至没有设置。此外，两者都在同一个安全组中

这是我的配置/sidekiq.rb：

rails_root = Rails.root || File.dirname(__FILE__) + '/../..'
rails_env = Rails.env || 'development'
redis_config = YAML.load_file(rails_root.to_s + '/config/redis.yml')
redis_config.merge! redis_config.fetch(Rails.env, {})
redis_config.symbolize_keys!

Sidekiq.configure_server do |config|
  config.redis = { url: "redis://#{ENV['REDIS_HOST']}:#{redis_config[:port]}/12" }
end

Sidekiq.configure_client do |config|
  config.redis = { url: "redis://#{ENV['REDIS_HOST']}:#{redis_config[:port]}/12" }
end

development:
  host: localhost
  port: 6379
test:
  host: localhost
  port: 6379
production:
  host: ENV['REDIS_HOST']
  port: 6379

REDIS_HOST: project-name-001.random-token.0001.use1.cache.amazonaws.com

我的配置/redis.yml：

rails_root = Rails.root || File.dirname(__FILE__) + '/../..'
rails_env = Rails.env || 'development'
redis_config = YAML.load_file(rails_root.to_s + '/config/redis.yml')
redis_config.merge! redis_config.fetch(Rails.env, {})
redis_config.symbolize_keys!

Sidekiq.configure_server do |config|
  config.redis = { url: "redis://#{ENV['REDIS_HOST']}:#{redis_config[:port]}/12" }
end

Sidekiq.configure_client do |config|
  config.redis = { url: "redis://#{ENV['REDIS_HOST']}:#{redis_config[:port]}/12" }
end

development:

production:
  host: ENV['REDIS_HOST']
  port: 6379

REDIS_HOST: project-name-001.random-token.0001.use1.cache.amazonaws.com

我的应用程序位于.yml：

rails_root = Rails.root || File.dirname(__FILE__) + '/../..'
rails_env = Rails.env || 'development'
redis_config = YAML.load_file(rails_root.to_s + '/config/redis.yml')

setup\u swap.config

、

sidekiq.config

和

nginx.config

我也看到过这个问题，但我认为它是不相关的。也许我错了？如果不相关，将在另一篇文章中讨论

Starting nginx: nginx: [warn] conflicting server name "localhost" on 0.0.0.0:80, ignored 

可能是什么？ 我遗漏了什么重要的东西吗

编辑：添加nginx.conf

更新2删除了对localhost端口80的重复引用，nginx停止抱怨，但我仍然收到

心跳错误，因为Redis配置为保存RDB快照，但当前无法在磁盘上保留。

错误

Sidekiq.redis（&:info）

的输出：

有趣的是，我找不到我的redis日志进行进一步的调查。在我的

redis.conf

中，我看到的只是这些

# Specify the log file name. Also the empty string can be used to force
# Redis to log on the standard output. Note that if you use standard
# output for logging but daemonize, logs will be sent to /dev/null
logfile ""

我甚至运行了

find/-path/sys-prune-o-path/proc-prune-o-name*redis*

，没有看到任何日志文件(╯°□°)╯︵ ┻━┻

同样奇怪的是，production.log根本没有写入，请检查权限：rw-r--r--1 webapp webapp 0 May 8 20:01 production.log

请共享您的

/etc/nginx/nginx.conf

，我猜

nginx.conf

文件夹中包含其他服务器conf文件，检查行

include/etc/nginx/conf.d/*.conf；

在您的

nginx.conf

中，如果是这样，它可能会加载两次文件或其他具有相同

服务器名称的默认文件，您可以将其更改为
include/etc/nginx/conf.d/webapp\u healthd.conf
或您想要的任何名称，但在检查机器上的文件是什么之前

如果有任何临时文件，如
~default
或
等，请检查
/etc/nginx/sites enabled/
目录。保存
。使用
ls-lah
检查它，删除它们，重新启动nginx并检查错误，或通过
ebextensions
执行此操作，然后重新部署

更新

尝试从
nginx.conf
中删除
服务器{…}
的所有部分，确保在
http
中包含您的文件
/etc/nginx/conf.d/webapp\u healthd.conf
，您已经有了

谢谢你的回复！我已经添加了
nginx.conf
文件，我确实注意到了
include/etc/nginx/conf.d/*.conf；
，但是当我去检查
/etc/nginx/sites enabled/
时，我没有发现任何东西。没有这样的目录……这意味着什么？另外，更改为include
webapp\u healthd.conf
（在机器上）。请参阅更新的描述@Berlini，认为这是因为在
nginx conf
和
webapp\u healthd.conf
中，您有一个侦听端口的服务器80@Berlin-非常感谢-出现了一个重复！仍然有
错误，因为Redis当前无法在磁盘上保存。
错误。尝试进行调查，但
Redis日志
简单y不存在于/var/logs中！？有什么想法吗？redis.conf就像阅读拉丁语一样。奇怪的是production.log根本没有被写入，请检查权限：
rw-r--r--1 webapp webapp 0 May 8 20:01 production.log
您在这台机器上为此env安装了本地redis吗？如果是，请告诉我，然后我们更改redisconf文件，什么是redis版本？您的
redis.conf
上唯一一行是
logfilg
？更改
nginx.conf
后现在发生的情况，您是否能够通过浏览器访问您的应用程序？
