Ansible 错误 Received exit status from master答案

【问题描述】：

我编写了一个看似简单的 ansible 任务来连接到 ec2 实例并配置时区。 ansible任务如下

---
- name: Set Time Zone variables
  copy: content='Etc/UTC' dest=/etc/timezone owner=root group=root mode=0644 backup=yes

用于运行任务的命令是

ansible-playbook nectar.yml  --extra-vars "ansible_python_interpreter=/usr/local/bin/python env=DEVELOPMENT" -vvvv

我的 ansible.cfg 看起来像

[defaults]
inventory = hosts

[ssh_connection]
ssh_args = -o ControlMaster=auto -o ControlPersist=60s

但我不断收到错误消息

关于为什么 ansible 在重用主连接时不断收到此错误的任何想法？

【问题讨论】：

您正在尝试在远程主机上执行/usr/local/bin/python，错误消息告诉您，它不存在。

标签： amazon-ec2 ssh ansible

【解决方案1】：

如果我必须在 vanilla ubuntu AMI 上运行某些东西，我已经在剧本之上做了类似的事情。

---
- hosts: all
  remote_user: someuser
  gather_facts: False
  pre_tasks:
    - name: Install python for Ansible
      raw: test -f /usr/bin/python || (apt -y update && apt install -y python-minimal)
      become: true
```

- setup: # aka gather_facts

【解决方案2】：

尝试在目标机器python上安装。我有同样的错误：

dworker-01 | FAILED! => {
    "changed": false,
    "module_stderr": "Shared connection to dworker-01 closed.\r\n",
    "module_stdout": "/bin/sh: 1: /usr/local/bin/python: not found\r\n",
    "msg": "MODULE FAILURE\nSee stdout/stderr for the exact error",
    "rc": 127
}

目标机器： apt-get update && apt-get install python
之后就OK了。
