1、docker下载镜像。

#我们查看一下docker.hup上的镜像。
[root@bfd-v7 ~]# docker search mysql

2、创建mysql的镜像,并运行。

[root@zhaokejin ~]# docker run -p 3308:3306 --name mysql01 -e MYSQL_ROOT_PASSWORD=123456 -d mysql
3b42e6847b993d0bafdd8226cfccd33d14ac3eb88c5bbe7171b0a8efebfd592f
[root@zhaokejin ~]# docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
3b42e6847b99        mysql               "docker-entrypoint..."   8 seconds ago       Up 7 seconds        0.0.0.0:3308->3306/tcp   mysql01

启动之后我们查看logs；

[root@zhaokejin ~]# docker logs mysql01

说明启动成功了；

然后我们进入docker中mysql

#进入mysql的终端：

[root@bfd-v7 ~]# docker exec -it mysql01 mysql -uroot -p123456

或者

# docker exec -ti xxx(容器id) /bin/bash

# mysql -u root -p

3、设置用户配置项

(1) 查看用户信息

mysql> select host,user,plugin,authentication_string from mysql.user;  
+-----------+------------------+-----------------------+------------------------------------------------------------------------+
| host      | user             | plugin                | authentication_string                                                  |
+-----------+------------------+-----------------------+------------------------------------------------------------------------+
| %         | root             | caching_sha2_password | $A$005$^]RQB}j~t!      .#v)3.UogPRFu8VJA5/GKEbK5edEQlMT5sHw2n72zYJNlIbo3 |
| localhost | mysql.infoschema | mysql_native_password | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE                              |
| localhost | mysql.session    | mysql_native_password | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE                              |
| localhost | mysql.sys        | mysql_native_password | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE                              |
| localhost | root             | caching_sha2_password | $A$005$Y6&q!59^Fmh)@-6TG58J3F5+3I/HI9L|JCadNG+-+d6W+1D_UFW+7MRD7F3 |
+-----------+------------------+-----------------------+------------------------------------------------------------------------+

备注：host为 % 表示不限制ip   localhost表示本机使用    plugin非mysql_native_password 则需要修改密码

navicat链接错误；我们继续往下看；

(2)修改用户密码

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'newpassword'; #更新一下用户的密码 root用户密码为newpassword  

mysql> ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';
Query OK, 0 rows affected (0.06 sec)

ok了；
