amazon-ec2 - EC2 AMI 2.4/2.5 dsc20/dsc21 依赖问题

Question

我正在尝试使用此 guidelines 创建一个 1 节点 Datastax 社区版集群在 EC2 m3.xlarge(欧盟西部)上。
这是提供的参数:

  --clustername cassandra
  --totalnodes 1
  --version community

正如指南中提到的，我打开了这些端口:

  22
  8888
  1024-65355

这是我在 ~/datastax_ami/ami.log 中发现的错误:

         The following packages have unmet dependencies:

相关 GitHub 问题: Add support for DSC 2.2 Versions #81

有没有人我做错了什么。
谢谢

Answer 1

依赖项存在错误 - 正如您所遇到的 - Add support for DSC 2.2 Versions #81并在 AMI 2.5 中修复。

因此请务必使用新的 AMI。 请勿使用:

DataStax Auto-Clustering AMI

这是 AMI 2.4 版本，而是使用:

DataStax Auto-Clustering AMI 2.5.1-pv

或者

DataStax Auto-Clustering AMI 2.5.1-hvm
