创建映射挂载卷目录

[[email protected] mysql8]# pwd
/opt/mysql8
[[email protected] mysql8]# mkdir conf
[[email protected] mysql8]# mkdir logs
[[email protected] mysql8]# mkdir data

docker 部署mysql8.0_mysql

在conf目录新建my.cnf

（五）、验证mysql版本

获取容器名

      
      
       
       [[email protected] ~]# docker ps
       
       
CONTAINER ID   IMAGE       COMMAND       CREATED       STATUS       PORTS        NAMES
       
       
8082f1   mysql:8.0   "  t.s…"     ago          hours   33060/tcp   06>3306/tcp   mysql8
      
      
      
      
       
       1.
       
       2.
       
       3.

docker 部署mysql8.0_mysql_02

进入容器内部查看mysql版本

      
      
       
       [[email protected] ~]# docker exec -it 808 bash
       
       
[email protected]:/# 
      
      
      
      
       
       1.
       
       2.

docker 部署mysql8.0_mysql_03

输入mysql -uroot -p ,输入部署的密码即可,8.0.29这是最新的8版本

      
      
       
       [email protected]:/# mysql -uroot -p
       
       
Enter password: 
      
      
      
      
       
       1.
       
       2.

      
      
       
       [email protected]:/# mysql -uroot -p
       
       
Enter password:

       15.

修改密码

使用select user,plugin from user where user='root'; 查看加密方式

      
      
       
       1、...  mysql;
       
       

       
       
2、ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '密码';
       
       

       
       
3、update user set host='%' where user='root';
       
       

       
       
4、flush privileges;
