amazon-web-services - CloudFormation - 在 EC2 实例上安装和配置 CloudWatch 代理

Question

我有一个使用 LaunchTemplate 创建 ec2 实例的 CloudFormation 模板，但我想将 cloudwatch 代理添加到实例中，但我不知道出了什么问题。

我有2个configSet，但是cfn-init卡在“02_download_app”> “Command run_app”，这部分我从/运行一个jar文件。

这是/var/log/cfn-init-cmd.log的输出，我注意到在命令run_app之后，jar卡住了17:25，一段时间后 17:42 我连接到实例，杀死 jar 并重新启动，它成功地继续执行脚本，我认为错误是一些编码问题，但我不知道在哪里: jar ？在log4j配置文件中？等等

2020-06-23 17:25:20,679 main ERROR Console contains an invalid element or attribute "Encoding"

    configSets:
      setup:
        - "01_install_java"
        - "02_download_app"
        - "03_setupCfnHup"
        - "04_config-amazon-cloudwatch-agent"
        - "05_restart_amazon-cloudwatch-agent"
      updateEnvironment:
        - "04_config-amazon-cloudwatch-agent"
        - "05_restart_amazon-cloudwatch-agent"

我关注了这个template ，这是我的模板的一部分和 cfn-init 部分。

我观看了/var/log/cloud-init-output.log，但没有任何错误线索，说这是一些编码问题，但在哪一步？

我猜你指的是这个sudo java -jar/tmp/app.jar &？我认为你应该在 test 完成后在 Init 中杀死它。

实现此目的的一种方法如下:

run_app:
    command: |
        sudo java -jar /tmp/app.jar &
        PROCESS_ID=$!
    test: "sudo ps -ef | grep java"
    cwd: "/"

run_app_kill:
    command: "sudo kill -9 $PROCESS_ID"

我认为一般情况下也不需要sudo。由于您没有对步骤进行编号，因此必须确保 run_app_kill 在 run_app 之后运行。
