1. 下载Mysql的Docker镜像：
[plain] view plain copy
$ docker search mysql (搜索mysql镜像)
$ docker pull mysql （下载mysql镜像，默认最新版本）
2. 运行镜像，设置root账号初始密码（123456），映射本地宿主机端口3306到Docker端口3306。测试过程没有挂载本地数据盘：
[plain] view plain copy
$ docker run -it --rm --name mysql -e MYSQL_ROOT_PASSWORD=123456 -p 3306:3306 -d mysql
3. 查看已运行的容器：
[plain] view plain copy
$ docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
a42f31094df5 mysql "docker-entrypoint.s…" 7 seconds ago Up 6 seconds 0.0.0.0:3306->3306/tcp mysql
4. 进入mysql容器：
[plain] view plain copy
docker exec -it mysql bash
root@a42f31094df5:/#
5. 在容器内登陆Mysql:
[sql] view plain copy
root@a42f31094df5:/# mysql -uroot -p123456 或 (mysql -uroot -p )

6. 查看用户信息
[html] view plain copy
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；
mysql> ALTER user 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';
Query OK, 0 rows affected (0.01 sec)
mysql>
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.01 sec)
mysql>
