ansible学习笔记11

1、综合实验01

1.1 实验要求

  1. 开启实验环境
  2. 安装ansible
  3. 进入review-deploy目录
    1. 创建invenory文件,dev组下有servera和serverb两个host
    2. 创建ansible.cfg文件,指定inventory存放位置
    3. 通过ad hoc,使用copy模块将字符串Managed by Ansible\n.复制到/etc/motd,并使用devops用户
    4. 通过ad hoc,使用command模块查看受管节点/etc/motd内容
    5. 判断成绩,实验结束

1.2 实验

[student@workstation ~]$ lab review-deploy start

 · Configuring control node packages...........................  SUCCESS
 · Creating working directory..................................  SUCCESS
# 安装ansible
