第一步
docker pull mysql第二步 在宿主机创建放置mysql的配置文件的目录，和数据目录,然后创建my.cnf配置文件
mkdir /usr/local/mysql_conf mkdir /usr/local/mysql_data vi /usr/local/mysql_conf/my.cnf附上mysql8.0默认的my.cnf 的内容

docker run -d --name mysql -v /usr/local/mysql_conf/my.cnf:/etc/mysql/my.cnf -v /usr/local/mysql_data:/var/lib/mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=root mysql 注意：密码不要设置成123456，因为mysql8.0密码校验比较严格，设置成123456去连接的时候会报mysql 2059错误 意思就是让你改密码-v 挂载宿主机目录和 docker容器中的目录
-d 后台运行
-p 映射容器端口号和宿主机端口号
-e 环境参数
