想要安装一个mysql服务实例，最简单的方式当然是用docker启动一个

只需一个命令搞定：

docker run --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 -d mysql

其中：  
–name 后面的是docker容器名  
\-e MYSQL\_ROOT\_PASSWORD 是设置mysql的root账号密码  
\-d mysql 是你的镜像标签

还可以加上 -v

#先创建目录和my.cf配置文件
       #mkdir -p /home/mysql/{conf,logs,data/mysql}
        -v /home/mysql/conf/my.cnf:/etc/mysql/my.cnf -v /home/mysql/logs:/logs -v /home/mysql/data/mysql:/var/lib/mysql

用来挂载数据目录、配置文件、日志等  
这样重启实例后数据不会丢失

如果连接Docker启动的mysql出现报错：  
ERROR 2059 (HY000): Authentication plugin ‘caching\_sha2\_password’ cannot be loaded  
解决办法，重新设置下密码：

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '12345678';

启动成功后：

[root@iZttsn6fen661yZ ~]# docker ps
