Ansible：curl 命令失败

我写了一本小剧本，它会随着时间的推移而增加。

首先我在删除服务器上编写了一个脚本，该脚本有权访问“https://dlcdn.apache.org/tomcat/tomcat-9/v9.0.65/bin/”并下载tomcat源，脚本文件的内容是

#!/bin/bash -x
version="9.0.65"
filename="apache-tomcat-"$version".tar.gz"
cd /root/ApacheTomcat/files
curl -fk https://dlcdn.apache.org/tomcat/tomcat-9/v9.0.65/bin/apache-tomcat-"$version".tar.gz -o $filename
if [[ -e /root/ApacheTomcat/files/$filename ]]
        then
                echo -e "\nApache Tomcat $version downloaded under $PWD on `hostname -i`"
else
        echo -e "\nProblem occured please check it"
fi

然后我在ansible控制器上写了一个小剧本，内容如下

---                                                         
- name: Download Latest version of Apache Tomcat            
  hosts: 172.16.8.50                                        
  tasks:                                                    
    - name: Downloading Apache on Central Repository Server 
      command: sh /root/ApacheTomcat/apachetomcat.sh        
      register: _check_download_apache_status               
    - name:                                                 
      debug:                                                
        var: _check_download_apache_status                  
...

如果我在服务器上运行 shell 脚本，它会工作并下载文件，但如果我通过 ansible playbook 运行它，它会给出此错误“无法解析主机：dlcdn.apache.org；未知错误”

ansible-playbook apache-update.yaml -b

关于

我写了一本小剧本，它会随着时间的推移而增加。

根据给定的评论，您可以简单地从一个例子开始，例如

---
- hosts: central_repository_server # or your remote hosts
  become: false
  gather_facts: false
  
  vars:
  
    VERSION: "9.0.65"

  tasks:
  
  - name: Download latest version of Apache Tomcat
    get_url:
      url: "https://dlcdn.apache.org/tomcat/tomcat-9/v{{ VERSION }}/bin/apache-tomcat-{{ VERSION }}.tar.gz"
      dest: "/home/{{ ansible_user }}"
    register: result
    environment:
      http_proxy: "localhost:3128"
      https_proxy: "localhost:3128"

由于我之前没有提供功能齐全且经过测试的解决方案，而只是提供了解决问题的想法和方法，因此请在此处找到一个工作示例。

---
- hosts: localhost
  become: false
  gather_facts: false

  vars:

    VERSION: "9.0.65"

  tasks:

  - name: Get file using 'uri' module
    uri:
      url: "https://dlcdn.apache.org/tomcat/tomcat-9/v{{ VERSION }}/bin/apache-tomcat-{{ VERSION }}.tar.gz"
      dest: "/home/{{ ansible_user }}"
      method: GET
      status_code: 200,304
      creates: "apache-tomcat-{{ VERSION }}.tar.gz"
    environment:
      http_proxy: "localhost:3128"
      https_proxy: "localhost:3128"
