将定制弹性豆茎原木加入cloudwatch小组

出现问题，无法从.eextensions/logs.config 创建自定义cloudwatch日志组

以下是我尝试过的不同文件。

--- 
files: 
/opt/elasticbeanstalk/tasks/bundlelogs.d/celery_logs.conf: 
content: |-
/var/log/celery_beat.stdout.log
/var/log/celery_flower.stdout.log
/var/log/celery_worker.stdout.log
/var/log/faust_worker.stdout.log
group: root
mode: "000755"
owner: root

--- 
files: 
"/opt/elasticbeanstalk/config/private/logtasks/bundle/applogs.conf" :
mode: "000755"
owner: root
group: root
content: |
/var/log/celery_beat.stdout.log
/var/log/celery_flower.stdout.log
/var/log/celery_worker.stdout.log
/var/log/faust_worker.stdout.log

packages:
yum:
awslogs: []
files:
"/etc/awslogs/awscli.conf" :
mode: "000600"
owner: root
group: root
content: |
[plugins]
cwlogs = cwlogs
[default]
region = `{"Ref":"AWS::Region"}`
"/etc/awslogs/config/logs.conf" :
mode: "000600"
owner: root
group: root
content: |
[/var/log/celery_beat.stdout.log]
log_group_name = `{"Fn::Join":["/", ["/aws/elasticbeanstalk", { "Ref":"AWSEBEnvironmentName" }, "/var/log/celery_beat.stdout.log"]]}`
log_stream_name = {instance_id}
file = /var/log/celery_beat.stdout.log
[/var/log/celery_flower.stdout.log]
log_group_name = `{"Fn::Join":["/", ["/aws/elasticbeanstalk", { "Ref":"AWSEBEnvironmentName" }, "/var/log/celery_flower.stdout.log"]]}`
log_stream_name = {instance_id}
file = /var/log/celery_flower.stdout.log
[/var/log/celery_worker.stdout.log]
log_group_name = `{"Fn::Join":["/", ["/aws/elasticbeanstalk", { "Ref":"AWSEBEnvironmentName" }, "/var/log/celery_worker.stdout.log"]]}`
log_stream_name = {instance_id}
file = /var/log/celery_worker.stdout.log
commands:
"01":
command: systemctl enable awslogsd.service
"02":
command: systemctl restart awslogsd

日志正确显示在文件中：

/var/log/celery_beat.stdout.log
/var/log/celery_flower.stdout.log
/var/log/celery_worker.stdout.log
/var/log/faust_worker.stdout.log

但是没有创建日志组，也没有向其传输日志。

我尝试过15种或更多类似的配置，但运气不佳。

有人留下了答案，但它被删除了，所以我继续，把它留在这里给你们。

我认为OP和我不能让它工作的原因是，我们按照本教程走错了路：

https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features.logging.html

在本教程中，他们教您在/opt/elasticbeanstalk/tasks/中使用conf文件，但这仅用于将日志导出到Elastic Beanstalk web控制台，而不是CloudWatch日志。

要将自定义日志导出到CloudWatch日志中，您必须使用本教程(这是OP问题中的选项#3(

https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/AWSHowTo.cloudwatchlogs.html

它特别地具有用于"；自定义日志文件流"--这是通过使用CCD_ 3安装名为CCD_。这个过程比简单地放入conf文件要复杂得多，但这就是必须要做的。

请确保还检查Elastic Beanstalk角色，以确保它具有与CloudWatch日志交互的权限。

最新的EC 2不再使用锥子。SSH到您的实例中，并通过键入检查您的实例是否使用最新的cloudwatch代理

sudo amazon-cloudwatch-agent-ctl -a status

如果它正在运行，请将以下配置文件添加到您的ebextensions中。

}
]
}
}
}
}

检查https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/install-CloudWatch-Agent-commandline-fleet.html用于附加将添加自定义日志文件的自定义配置文件。

中解释了配置文件的生成https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/create-cloudwatch-agent-configuration-file-wizard.html.您可以通过运行向导生成适合您的情况的配置文件，并根据结果更改下面文件的内容。

https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/UseCloudWatchUnifiedAgent.html

最后，确保你的elasticbeanstalliam配置文件有权在你的iam配置中写入cloudwatch日志

Amazon Linux 2不再支持/opt/elasticbeanstall/和awslogs

要配置自定义日志，请遵循以下方法。

在应用程序的根目录中创建一个.platform/hooks/postdeploy/
根据需要创建一个带有日志路径的shell脚本
将shell脚本放在扩展名为.sh的/postdeploy目录中
在Elasticbeanstalk控制台配置中设置了一个环境变量，我们稍后将在脚本中获取该变量
您应该看到您的自定义日志在cloudwatch中进行流式传输

#!/bin/bash
ENV_NAME=$(/opt/elasticbeanstalk/bin/get-config environment | jq -r '.ENV_NAME')
cat > /opt/aws/amazon-cloudwatch-agent/etc/amazon-cloudwatch-agent.d/file_beanstalk.json <<EOF

]
}
}
}
}
EOF
sudo sudo systemctl restart amazon-cloudwatch-agent
