我是一个完整的Ansible新手,所以提前道歉!
我正在尝试运行一个Ansible手册,其作用是在本地和远程机器上构建的程序之间启用文件共享/传输/同步(正如你猜测的那样,我没有写剧本)。
我的问题是,当我不使用--connection = local时,我无法ping远程主机。但是,我可以ssh远程主机。当我运行剧本时,它会抛出错误:
host1 | UNREACHABLE! => {
"changed": false,
"msg": "Failed to connect to the host via ssh.",
"unreachable": true}
如果我这样做
ansible-playbook cvfms.yml --connection=local
然后我没有得到ssh错误,但是剧本无法做任何事情,因为我怀疑连接应该不是本地连接才能运行。
有关详细信息,请参阅我的/ etc / ansible / hosts文件:
[group_name]
host1 ansible_ssh_host=lengau.chpc.ac.za
我还有一个/ etc / ansible / host_var,在机器上说我的用户名。
对此问题的任何帮助都将深表感谢!
回答评论:当我运行ansible-playbook -vvv cvfms.yml时,我得到输出:

回答另一个问题: 我设置了这样的私钥:
在我的家中&#34;机器我现在有一个文件/home/testuser/.ssh/id_rsa,其中包含我通过
获得的私钥ssh-keygen -t rsa.
此私钥也存储在远程计算机上的目录/home/user/.ssh/中。
据我所知,这是正确的做法。
当我运行ansible-playbook或ping时,我仍然遇到与上述相同的问题。
并且为了增加一些古怪,所有这一切只有在我是根的时候才会发生。如果我是家庭计算机上的普通用户,则ssh工作正常,并且该剧本在本地连接上运行,并显示新的错误消息,如下所示:
ansible-playbook cvmfs.yml --connection=local

在我的本地机器上有些东西严重错误,我想......
答案 0 :(得分:0)
我找到了答案!我觉得既高兴又愚蠢(脸红)......
问题是通过(执行上述所有步骤后)运行:
来解决的ansible-playbook cvmfs.yml --ask-pass
在此之后它运行正常。
的输出ansible all -m ping --ask-pass
在所有情况下都是“成功”,而不仅仅是在本地网络上。剧本运行良好。耶!
