ssh - Ansible 无法连接到 AWS EC2 实例

Question

我正在尝试使用 Ansible 从 Codeship 构建连接到 AWS EC2 实例。这在另一个 AWS 区域 (eu-west-1) 中运行良好，但现在我想在 us-east-1 中设置服务器，但出现以下错误:

我可以使用像这样的简单 ssh 命令进行连接 ssh ec2-user@ec2-52-11-9-45.compute-1.amazonaws.com所以我很确定 ssh key 设置正确。唯一的区别是区域和 AMI，但在这两种情况下，AMI 都是 Amazon Linux。

有人可以告诉我问题或指出正确的方向。

Answer 1

Failed to connect to new control master

意味着您在使用控制连接时遇到问题(连接到您的控制套接字文件)。检查权限或删除套接字文件，然后重试。

通常这些设置在您的 ~/.ssh/config 中，所以要么禁用它( ControlMaster no )或更改路径(例如 ControlPath /tmp 或检查此 post )。

由于您使用的是 Ansible，您可以在 ansible.cfg 中禁用控制连接。 (例如 /etc/ansible/ansible.cfg ):

ssh_args = -o ControlMaster=no

按照这个 post .或者尝试禁用 accelerate如果启用(按照这个 post ):

accelerate: false

然后再试一次。
