【问题描述】：

我有一个 ansible 播放文件，它必须执行两个任务，首先在本地机器上获取磁盘使用情况，另一个任务是获取远程机器的磁盘使用情况并在远程机器上安装 apache2。

当我尝试运行文件时，我收到错误 “错误！'sudo' 不是 Play 的有效属性” 当我从 yml 文件中删除 sudo 和 apt 部分时，它运行良好。

我正在使用 ansible 2.9.4。以下是两个剧本文件：

文件运行没有任何错误，

--- 
- 
  connection: local
  hosts: localhost
  name: play1
  tasks: 
    - 
      command: "df -h"
      name: "Find the disk space available"
    - 
      command: "ls -lrt"
      name: "List all the files"
    - 
      name: "List All the Files"
      register: output
      shell: "ls -lrt"
    - 
      debug: var=output.stdout_lines
- 
  hosts: RemoteMachine1
  name: play2
  tasks: 
    - name: "Find the disk space"
      command: "df -h"
      register: result
    - debug: var=result.stdout_lines

文件运行出错：

--- 
- 
  connection: local
  hosts: localhost
  name: play1
  tasks: 
    - 
      command: "df -h"
      name: "Find the disk space available"
    - 
      command: "ls -lrt"
      name: "List all the files"
    - 
      name: "List All the Files"
      register: output
      shell: "ls -lrt"
    - 
      debug: var=output.stdout_lines
- 
  hosts: RemoteMachine1
  name: play2
  sudo: yes
  tasks: 
    - name: "Find the disk space"
      command: "df -h"
      register: result
    - name: "Install Apache in the remote machine" 
      apt: name=apache2 state=latest
    - debug: var=result.stdout_lines

完整的错误信息：

ERROR! 'sudo' is not a valid attribute for a Play

The error appears to be in '/home/Documents/ansible/play.yml': line 20, column 3, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

-
  hosts: RemoteMachine1
  ^ here

【解决方案1】：

Ansible play 关键字 sudo 是（很久以前）deprecated with warnings in version 2.0 and removed in version 2.2

请参阅actual supported play keywords。使用：

become: true

【解决方案2】：

-  hosts: RemoteMachine1
   name: play2
   become: yes
   tasks: 
      - name: "Find the disk space"
        command: "df -h"
        register: result
      - name: "Install Apache in the remote machine" 
        apt: name=apache2 state=latest
      - debug: var=result.stdout_lines

use become: 是的，它将以 root 用户身份运行您的任务。
