1.安装MysqL5.6

docker run MysqL:5.6

等所有项目都是Download complet 安装完毕

Status: Downloaded newer image for MysqL:5.6
error: database is uninitialized and password option is not specified 
  You need to specify one of MysqL_ROOT_PASSWORD,MysqL_ALLOW_EMPTY_PASSWORD and MysqL_RANDOM_ROOT_PASSWORD

2.使用本地账号创建一个文件夹用来映射docker中MysqL的配置文件
其中继续创建conf、data、logs 3个文件夹
我的配置如下

val@val-linux:~/docker/MysqL1$ pwd
/home/val/docker/MysqL1
val@val-linux:~/docker/MysqL1$ ls
conf  data  logs

3.创建MysqL容器
切换到root账号进入到刚才创建的MysqL1文件夹中

root@val-linux:/home/val# cd /home/val/docker/MysqL1/
root@val-linux:/home/val/docker/MysqL1# 

创建并启动容器

docker run -p 33061:3306 --name MysqL1 -v $PWD/conf:/etc/MysqL -v $PWD/logs:/logs -v $PWD/data:/MysqL_data -e MysqL_ROOT_PASSWORD=123456 -d MysqL:5.6

用本地33061端口映射docker的3306端口
给容器命名MysqL1
用本地/home/val/docker/MysqL1/conf映射MysqL的conf
用本地/home/val/docker/MysqL1/logs映射MysqL的logs
用本地/home/val/docker/MysqL1/data映射MysqL的MysqL_data
给root设置密码123456

4.启动MysqL容器

docker start MysqL1

5.进入MysqL的bash

docker exec -it MysqL1 env LANG=C.UTF-8 bash

其中 env LANG=C.UTF-8 bash 让docker命令行支持中文

6.复制配置文件

cp /usr/my.cnf /etc/MysqL/my.cnf

7.登录MysqL

MysqL -u root -p

输入密码进入

8.查看MysqL编码

MysqL> show variables like '%character%';
+--------------------------+----------------------------+
| Variable_name            | Value                      |
+--------------------------+----------------------------+
| character_set_client     | latin1                     |
| character_set_connection | latin1                     |
| character_set_database   | latin1                     |
| character_set_filesystem | binary                     |
| character_set_results    | latin1                     |
| character_set_server     | latin1                     |
| character_set_system     | utf8                       |
| character_sets_dir       | /usr/share/MysqL/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.01 sec)

发现不是utf-8编码

9.修改MysqL编码
退出MysqL，退出docker

MysqL> exit
Bye
root@8b83a30acbf8:/# exit
exit
root@val-linux:/home/val/docker/MysqL1# 

修改my.cnf配置文件

root@val-linux:/home/val/docker/MysqL1# vim conf/my.cnf 

按i进入编辑模式
加入

[client] default-character-set=utf8  
[MysqL] default-character-set=utf8  
[MysqLd] character-set-server=utf8

esc :wq! 保存退出

10.重启docker的MysqL再次查看编码

root@val-linux:/home/val/docker/MysqL1# docker stop MysqL1
MysqL1
root@val-linux:/home/val/docker/MysqL1# docker start MysqL1
MysqL1
root@val-linux:/home/val/docker/MysqL1# docker exec -it MysqL1 env LANG=C.UTF-8 bash
root@8b83a30acbf8:/# MysqL -u root -p
Enter password:

+--------------------------+----------------------------+
8 rows in set (0.00 sec)

11.创建数据库

MysqL> create database rise;
Query OK,1 row affected (0.00 sec)  
 
MysqL> use rise;
Database changed

12.创建用户并授权

MysqL> grant all privileges on rise.* to val@'%' identified by '123456';
Query OK,0 rows affected (0.00 sec)
 
MysqL> flush privileges;
Query OK,0 rows affected (0.00 sec)

%表示任意IP（可以指定IP）、val是用户名、123456是密码

ok完工
