使用Ansible的流氓配置失败

Question

我正在尝试配置Vagrant和Ansible的Ubuntu。我正在与this article一起工作，并遇到如下所示的错误。

Ansible failed to complete successfully. Any error output should be 
visible above. Please fix these errors and try again.

我目录的结构是：

vagrant-project 
├── Vagrantfile 
└── playbook.yml 

---

Vagrantfile包含：

# -*- mode: ruby -*- 
# vi: set ft=ruby : 

Vagrant.configure("2") do |config| 
    config.vm.box = "ubuntu/xenial64" 
    config.vm.network "forwarded_port", guest: 80, host: 8080 
    config.vm.provision :ansible do |ansible| 
    ansible.playbook = "playbook.yml" 
    end 
end 

---

playbook.yml包含：

--- 
- hosts: all 
    sudo: true 
    tasks: 
    - name: update apt cache 
     apt: update_cache=yes 
    - name: install apache 
     apt: name=apache2 state=present 
    - name: install mysql 
     apt: name=mysql-server state=present 
    - name: install php 
     apt: name=php5 state=present 

---

我使用：

• 流浪1.9.4
• 的VirtualBox 5.1.22
• Ansible 2.3.0.0

---

它们几乎与本文中显示的代码相同。你能告诉我什么是错的，以及如何成功地配置它？

谢谢。

Answer 1

正如康斯坦丁苏沃洛夫所说，这是一个可能的重复提到的职位。要回答你的问题，当在远程主机上执行任务时，默认情况下，除python可在/ usr/bin/python中使用外。但在Ubuntu 16.04中/usr/bin/python不可用，只有/ usr/bin/python3或/usr/bin/python3.5可用。

我们可以通过两种方式解决这个问题，

1）使用在pre_tasks部分原始模块，开始ansible任务之前安装python2，所以在/ usr/bin中/ Python的是可用的。然后，剧本将成为

--- 
- hosts: all 
    sudo: true 
    gather_facts: False 

    pre_tasks: 
    - raw: test -e /usr/bin/python || (apt -y update && apt install -y python-minimal) 
    - setup: 

    tasks: 
    - name: update apt cache 
     apt: update_cache=yes 
    - name: install apache 
     apt: name=apache2 state=present 
    - name: install mysql 
     apt: name=mysql-server state=present 
    - name: install php 
     apt: name=php5 state=present 

或者

2）使用ansible_python_interpeter变量，在这种情况下，流浪汉文件将成为

# -*- mode: ruby -*- 
# vi: set ft=ruby : 

Vagrant.configure("2") do |config| 
    config.vm.box = "ubuntu/xenial64" 
    config.vm.network "forwarded_port", guest: 80, host: 8080 
    config.vbguest.auto_update = false 
    config.vm.provision :ansible do |ansible| 
    ansible.playbook = "playbook.yml" 
    ansible.extra_vars = { 
     ansible_python_interpreter: "/usr/bin/python3.5", 
    } 
    end 
end
