我的SSH使用密钥设置正确。
ssh admin@192.168.1.111
admin@DiskStation:~$
但Ansible返回错误:

有人可以帮助我吗?

Ansible返回&#34;无法访问&#34;对于SFTP连接,而不是SSH。
在目标节点(或中间的防火墙)上启用SFTP,或在ansible.cfg
中将Ansible配置为use SCP:
scp_if_ssh = True

我有类似的&#34;无法到达&#34;错误,但在我的情况下,这是因为我的playbook文件以这种方式指定了主机:
[webservers] ubuntu@123.456.789.111
这在过去对我们有用,所以可能这适用于一些Ansible版本,但不适用于我的版本(2.0.0.2)。相反,我将其更改为文档建议的内容:
[webservers] 123.456.789.111 ansible_user=ubuntu
现在SFTP连接不会失败。

请检查目标计算机上是否安装了python。这是先决条件。
sudo apt install python3
sudo apt install python
sudo apt install python-minimal

经过多年的尝试和错误,现在我的ansible.cfg
上始终具有这些设置:
[defaults]
host_key_checking = false
[ssh_connection]
ssh_args = -o ControlMaster=auto -o ControlPersist=60s -o UserKnownHostsFile=/dev/null -o ServerAliveInterval=20
scp_if_ssh = True
[connection]
pipelining = true
pipelining
是我个人在处理多个
主机。 ssh_args
处理挂起和超时,这在目标遥控器的连接不稳定时很有用。
