mysql8安装和驱动jar包下载

方式一：基于docker安装 下拉镜像

docker pull mysql:8.0.21

启动镜像 docker run -p 3307:3306 --name mysql -e MYSQL_ROOT_PASSWORD=hadoop -d mysql:8.0.21

启动成功后，进入容器内部拷贝配置文件，到宿主主机 docker cp mysql:/etc/mysql /home/summer/mysql8

拷贝容器的 /etc/mysql目录到 主机目录/home/summer/mysql8

删除mysql容器，重新创建容器 docker stop mysql docker rm mysql

启动mysql ，挂载配置文件，数据持久化到宿主主机 启动脚本 文件名为mysql8.0.21.sh

#!/bin/sh docker run \ -p 3307:3306 \ --name mysql \ --privileged=true \ --restart unless-stopped \ -v /home/summer/mysql8/mysql:/etc/mysql \ -v /home/summer/mysql8/logs:/logs \ -v /home/summer/mysql8/data:/var/lib/mysql \ -v /etc/localtime:/etc/localtime \ -e MYSQL_ROOT_PASSWORD=hadoop \ -d mysql:8.0.21

命令解释： -p 端口映射

--privileged=true 挂载文件权限设置

--restart unless-stopped 设置 开机后自动重启容器

-v /home/summer/mysql8/mysql:/etc/mysql 挂载配置文件

-v /home/summer/mysql8/logs:/logs \ 挂载日志

-v /home/summer/mysql8/data:/var/lib/mysql \ 挂载数据文件 持久化到主机，

-v /etc/localtime:/etc/localtime 容器时间与宿主机同步

-e MYSQL_ROOT_PASSWORD=hadoop 设置密码

-d mysql:8.0.21 后台启动,mysql

执行脚本 启动镜像

大功告成，挂载出来了数据文件以及配置文件实现数据持久化
