Question

简介

一个月以来，我一直在运行以下命令：

ansible-playbook -vvvvi host_test rhel-tests.yml

通过SSH连接并成功在主机上运行测试，没有任何问题。但是截至最近几天，我在运行时收到以下消息：

fatal: [10.2.16.2]: UNREACHABLE! => {
    "changed": false, 
    "unreachable": true
}

MSG:

Failed to connect to the host via ssh: OpenSSH_7.6p1, LibreSSL 2.6.2
debug1: Reading configuration data /etc/ssh/ssh_config

即使我可以从运行的主机建立从bash到10.2.16.2的普通SSH连接，也可以。

host_test的内容如下：

[rhel]
10.2.16.2 node_type=xxx

[rhel:vars]
ansible_become=yes

Escalation succeeded

我的想法

目标上的配置更改不断发生，因此有可能在ssh中配置了某些内容以某种方式限制连接。
正在将测试添加到rhel-tests.yml中，因此现在可能触发了以前没有的某种超时。我已经尝试将rhel7的版本还原到一个月前，但是该命令仍然失败，因此我相信这不太可能是原因。
我正在使用通过brew安装的ansible 2.5.4版本。我尝试过更新到Ansible 2.6.2，但这似乎无济于事。
我尝试了其他在线建议，包括使用paramiko_ssh连接类型，但同样失败。
我可以跑步ansible -i hosts_test -m ping 10.2.16.2并拿回乒乓球
This question似乎很接近我的问题，但是rhel-tests.yml中没有任何行可以重启或关闭。

问题

是什么原因导致我的剧本失败以及如何解决？

Answer 1

我认为由于您的游戏缺乏输出，连接可能会断开。

在ssh_args中的ansible.cfg中添加以下内容：

-o ServerAliveInterval=50

Ansible停止通过SSH连接到主机
