1、介绍

ansible是一款开源自动化平台，是一个配置管理工具，自动化运维工具

2、ansible的工作流程介绍

安装ansible：yum install -y ansible；

执行一条简单的shell指令：

ansible test -m shell -a "uname -a"
192.168.56.102 | CHANGED | rc=0 >>
Linux node1 3.10.0-1160.el7.x86_64 #1 SMP Mon Oct 19 16:18:59 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

指令执行成功，回显中展示了指令执行的状态(rc=0)以及指令的执行结果；

打开ansible debug日志： export ANSIBLE_DEBUG=True，查看执行日志：

在debug日志中我们可以看出，ansible主要的执行流程有：

• 获取inventory: 即读取用户输入的host文件（ansible -i hosts）或者默认的/etc/ansible/hosts文件，从而获取到用户输入的指令需要在哪些物理机器上执行；
• 加载plugins目录下的所有的插件；
• 获取用户输入的参数（如果有）；
• 获取指令执行的策略（linear或者free），默认为linear；linear 策略即线性执行策略。线性执行策略指主机组内所有主机完成一个任务后才继续下一个任务的执行。free 策略即自由策略，即在一个 play 执行完之前，每个主机都各顾各的尽可能快的完成 play 里的所有任务，而不会因为其他主机没执行完任务而等待；
• 将要执行的指令作为一个任务加入到任务队列，任务真正的执行阶段通过迭代任务队列获取下一个需要执行的任务；
• 执行任务：ansible中执行某个指令并不是直接将指令发到远端去执行（因为要兼容不同的平台），而是将指令和ansible的模板脚本（python脚本）打包一起发到要执行的节点，解压并import需要的包，获取当前平台的python版本（interpreters），执行python脚本（low_level_execute_command(): executing: /bin/sh -c 'chmod u+x /root/.ansible/tmp/ansible-tmp-1684477395.81-9044-262581187543020/ /root/.ansible/tmp/ansible-tmp-1684477395.81-9044-262581187543020/AnsiballZ_command.py && sleep 0'），获取执行结果，然后清理现场之后返回；
