1. Ansible-playbook实现MySQL的二进制部署

1.1 架构及主机

Ansible-playbook实现MySQL8.0.27的二进制部署_mysql

五台主机
1  Ansible主控端：
节点1：（只设一个节点）
主机名：Ansible-PRI
CentOS 8.4
IP: 192.168.250.8/24
ansible 2.9.27

2  Ansible被控端--CentOS7组：
节点1：
主机名：Ansible-IP17
CentOS 7.9
IP: 192.168.250.17/24

节点2：
主机名：Ansible-IP27
CentOS 7.9
IP: 192.168.250.27/24

3. Ansible被控端--CentOS8组：
节点1：
主机名：Ansible-IP18
CentOS 8.4
IP: 192.168.250.18/24

节点2：
主机名：Ansible-IP28
CentOS 8.4
IP: 192.168.250.28/24

4. Ansible被控端--DBS组：
节点1：
主机名：Ansible-IP58
CentOS 8.4
IP: 192.168.250.58/24

节点2：
主机名：Ansible-IP68
CentOS 8.4
IP: 192.168.250.68/24

# 说明：按照上面的架构图，准备好五台不同组别和操作系统的主机，将以此为基础环境完成ansible的参数等学习和案例实践

1.2 Ansible 主控端准备

1.2.1 主控端环境准备及软件包安装

基本任务：同步时钟；安装ansible；查看版本并了解文件格式和基本语法等

# 主控端服务器CentOS8.4 上基本配置
[root@CentOS84 ]#hostnamectl set-hostname Ansible-PRI
[root@CentOS84 ]#exit
[root@Ansible-PRI ]#
[root@Ansible-PRI ]#hostname -I
192.168.250.8 
[root@Ansible-PRI ]#systemctl enable --now  chronyd.service

# Ansible 走的是EPEL源，如果没配置的话需要配置或者启用
[root@Ansible-PRI ]#yum repolist

Description  : Ansible is a radically simple model-driven configuration management,
             : multi-node deployment, and remote task execution system. Ansible works
             : over SSH and does not require any software or daemons to be installed
             : on remote nodes. Extension modules can be written in any language and
             : are transferred to managed machines automatically.
