Question

我使用Ansible和Vagrant。但是，我正在手动运行我的剧本。 Ansible总是在第一次运行时失败：

ansible-playbook -i cluster_hosts site.yml  --tags setup_db --limit slave1

报告：

PLAY [database] *************************************************************** 

GATHERING FACTS *************************************************************** 
fatal: [slave1] => SSH encountered an unknown error during the connection. We recommend you re-run the command using -vvvv, which will enable SSH debugging output to help diagnose the issue

TASK: [postgresql | Copy source list] ***************************************** 
FATAL: no hosts matched or all hosts have already failed -- aborting


PLAY RECAP ******************************************************************** 
           to retry, use: --limit @/home/robe/site.retry

slave1                     : ok=0    changed=0    unreachable=1    failed=0

我又跑了，它过去了。为什么ansible与第一个失败？

更新

使用 -vvvv 选项

运行

Answer 1

您是否使用包含自定义广告资源文件的专用网络？可能有时虚拟机网络在附加适配器上尚未完全运行。（vagrant使用默认值并认为一切都在线）

一个简单的解决方法是增加超时时间：

ansible.raw_arguments = ['--timeout=300']

见这里：https://github.com/mitchellh/vagrant/issues/4860

Answer 2

您尝试使用ansible配置的计算机不接受/正在侦听SSH，或者您遇到网络问题。这是输出的关键部分：

ssh: connect to host 192.168.1.13 port 22: Connection timed out

目标框是否正在运行sshd？
