amazon-web-services - AWS Cloudformation 用户数据问题

Question

我在启动传递用户数据的云信息模板时遇到问题。好像里面没有运行任何命令。实例无需运行这些命令即可正常运行。请帮忙解决。

Answer 1

所以我看不出你的脚本有什么问题。但我建议采取以下行动；

1. 脚本的可执行标志，因此

   chmod +x /opt/sonar/bin/linux-x86-64/sonar.sh
   

2. 出于调试目的，添加以下行

   exec > >(tee /var/log/user-data.log|logger -t user-data -s 2>/dev/console) 2>&1
   

所以你的用户数据应该是这样的；

    #!/bin/bash -xe
    exec > >(tee /var/log/user-data.log|logger -t user-data -s 2>/dev/console) 2>&1
    sudo chown -R ec2-user:ec2-user /opt/sonar/temp/conf
    chmod +x /opt/sonar/bin/linux-x86-64/sonar.sh
    /opt/sonar/bin/linux-x86-64/sonar.sh start

附加行取自 aws docs ;

To troubleshoot issues on your EC2 instance bootstrap without having to access the instance through SSH, you can add code to your user-data bash script that redirects all the output both to the /var/log/user-data.log and to /dev/console. When the code is executed, you can see your user-data invocation logs in your console.
