篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了利用Ansible的Playbook实现简单的案例和http的简单介绍相关的知识，希望对你有一定的参考价值。
1、ansible-playbook实现mysql5.7.37的二进制部署
1.1、简单的架构和主机准备
上面的图是我用来做学习的简单小实验用的
主机的准备：7台虚拟机
1、Ansible主控制端：
主机名：ansible
系统：CentOS 8.5
IP: 10.0.0.8
ansible版本：2.9.27
2、Ansible被控制端-webserver组
主机1：
主机名：web1
系统：CentOS 7.9
IP: 10.0.0.7
主机2：
主机名：web2
系统：CentOS 7.9
IP: 10.0.0.17
3、Ansible被控制端-dbserver组
主机1：
主机名：db1
系统：ubuntu18.04
IP: 10.0.0.100
主机2：
主机名：db2
系统：ubuntu18.04
IP: 10.0.0.102
4、Ansible被控制端-webserver组
主机1：
主机名：app1
系统：CentOS 8.5
IP: 10.0.0.18
主机2：
主机名：app2
系统：CentOS 7.9
IP: 10.0.0.271.2、Ansible主机的准备
1.2.1、ansible主机环境的准备以及软件包的安装
[root@Centos8 ~]#hostnamectl set-hostname ansible
[root@Centos8 ~]#exit
[root@ansible ~]#hostname -I
10.0.0.8
#默认ansible的版本
[root@ansible ~]#yum info ansible

#编写完后运行运行脚本，实现key验证
