1、ansible-playbook实现mysql的二进制部署
准备安装介质和配置文件

[root@CentOS84 data]# tree file
file
├── my.cnf
└── mysql-5.7.35-linux-glibc2.12-x86_64.tar.gz
[root@CentOS84 data]# cat file/my.cnf
[mysqld]
datadir=/data/mysql
log_bin=1
server_id=1
skip_name_resolve=1
socket=/data/mysql/mysql.sock
log-error=/data/mysql/mysql.log
pid-file=/data/mysql/mysql.pid
[client]
socket=/data/mysql/mysql.sock

ansible-playbook安装脚本
[root@CentOS84 data]# cat mysql_install2.yaml
---
- hosts: db
remote_user: root
gather_facts: no

vars:
version: "mysql-5.7.35-linux-glibc2.12-x86_64"
suffix: "tar.gz"
file: "version.suffix"
password: "mysql123"

tasks:
- name: 创建用户组
group: name=mysql gid=306
- name: 创建用户并加入到组
user: name=mysql uid=306 group=mysql shell=/sbin/nologin system=yes create_home=no home=/data/mysql
- name: 拷贝并解压文件
unarchive: src=https://www.songbingjia.com/data/file/file dest=/usr/local/
- name: 创建链接文件
file: src=https://www.songbingjia.com/usr/local/version dest=/usr/local/mysql state=link owner=mysql group=mysql
- name: 配置环境变量
shell: "echo PATH=/usr/local/mysql/bin:$PATH > /etc/profile.d/mysql.sh"
- name: 环境变量生效
shell: source /etc/profile.d/mysql.sh
- name: 创建数据目录
file: name=/data/mysql state=directory owner=mysql group=mysql
- name: 拷贝配置文件
copy: src=https://www.songbingjia.com/data/file/my.cnf dest=/etc/my.cnf
- name: 初始化数据文件
shell: mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/data/mysql
- name: 拷贝启动脚本
shell: /bin/cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
- name: 启动mysql服务
shell: chkconfig --add mysqld & & service mysqld start
- name: 更改root口令password
shell: mysqladmin -uroot passwordpassword

执行过程如下：
[root@CentOS84 data]# ansible-playbook mysql_install2.yaml
