Question

我正在测试Ansible，看看它是否可以为我们的嵌入式环境中的更新系统提供可行的后端。我完全没有问题。

我有两台机器，通过以太网连接，可以通过ssh相互通信。两者都有python 2.7，openssh作为ssh客户端并运行ssh服务器。两者都有ssh-key身份验证。我可以从控制机器ssh到另一台机器并在那里调用python而没有任何问题。 Ansible可以在本地机器上运行，但是根本无法操作rmeote机器。

使用此主机文件：

localhost              ansible_connection=local
192.168.100.212        ansible_connection=ssh ansible_ssh_private_key_file=~/.ssh/id_rsa

电话

ansible all -a "echo Hello World!"

失败，显示以下消息：

localhost | success | rc=0 >>
Hello World!

我无法确定导致此问题的原因。我已经测试了一个更广泛的playbook，它在localhost上执行整个操作没有问题，但在远程机器上使用相同的stascktrace失败。

Answer 1

管理发现它是由于缺少sftp客户端，配置它与scp一起工作就行了。

Answer 2

试试这个，它应该有效！

$ ssh-copy-id -i /home/(*UserName*)/.ssh/id_rsa.pub (*dest: hostname/IPADDR*)

Ansible在远程节点上失败基本回声
