尽管标准 ssh 可以运行，但 Ansible SSH 出现错误

我想将剧本应用到本地主机

ansible-playbook site.yml --limit localhost -vvvv

我得到了

fatal: [127.0.0.1]: UNREACHABLE! => {"changed": false, "msg": "SSH Error: data could not be sent to the remote host. Make sure this host can be reached over ssh", "unreachable": true}

如果我运行ssh localhost它就可以正常工作。配置：

$ cat ansible.cfg
[defaults]
hostfile = hosts
remote_user = root
host_key_checking = False

[ssh_connection]
control_path = /tmp
ssh_args = -o ControlMaster=no

您需要将连接设置local为 localhost。

host_vars/localhost创建与您的剧本相关的文件，其中包含以下内容：

---

ansible_connection: local

...

或者，您可以使用该选项调用 ansible-playbook，--connection=local但如果您想将任务委托给本地主机，最好将上述文件放在适当位置。
