如何在未在 aws 中运行的 ubuntu 服务器上安装 cloudwatch 代理？
我下载了这个ubuntu的dep包并安装在服务器上
wget https://amazoncloudwatch-agent.s3.amazonaws.com/ubuntu/amd64/latest/amazon-cloudwatch-agent.deb
与
dpkg -i -E ./amazon-cloudwatch-agent.deb
我也开始了
amazon-cloudwatch-agent-config-wizard
生成一个简单的配置。
./amazon-cloudwatch-agent-config-wizard

身份验证如何进行？我是否需要安装 AWS cli，或者是否可以仅使用此软件包运行监控。
如果是，怎么办？
不需要，运行 CloudWatch 代理不需要 AWS CLI。
它单独且独立地工作，但请注意，如果您愿意，您可以使用
aws configure但是，代理配置向导会询问您在哪里安装代理。如果您回答说您没有将其安装在 EC2 实例上，它会要求您提供要使用的 AWS 凭证。然后，它会在配置文件中设置正确的配置文件 (
~/.aws/config~/.aws/credentials关键是让
AmazonCloudWatchAgent无论您如何执行此操作，都取决于您 - 通过
