Question

I've written a seemingly simple ansible task to connect to an ec2 instance and configure the timezone. The ansible task is as follows

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

and the command used to run the task is

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

my ansible.cfg looks like

[defaults]
inventory = hosts

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

But I keep getting the error message

<54.237.211.85> ESTABLISH SSH CONNECTION FOR USER: ubuntu

Any ideas on why ansible keeps getting this error when reusing the master connection?

Answer 1

如果我要在香草ubuntu AMI上运行某些东西，那就在playbook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

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，一切都好。

Ansible error Received exit status from master
