【Mac OS】如何在本机中链接Docker中的mysql数据库

1. 在Mac中打开Terminal

Michaels-MacBook-Pro-3:workspace-architect michaelzhang$ docker pull mysql:5.6
5.6: Pulling from library/mysql
d599a449871e: Pull complete 
f287049d3170: Pull complete

Digest: sha256:5345afaaf1712e60bbc4d9ef32cc62acf41e4160584142f8d73115f16ad94af4
Status: Downloaded newer image for mysql:5.6

2. 查看mysql镜像

Michaels-MacBook-Pro-3:workspace-architect michaelzhang$ docker images
REPOSITORY                               TAG                 IMAGE ID            CREATED             SIZE
mysql                                    5.6                 e143ed325782        4 weeks ago         302MB
 

3. 启动mysql的容器

其中 docker run是启动容器的命令；i是交互式操作，t是一个终端，d指的是在后台运行，

-P指在本地生成一个随机端口，用来映射mysql的3306端口，mysql指运行mysql镜像，5.6是Tag的值，bash指创建一个交互式shell。

Michaels-MacBook-Pro-3:workspace-architect michaelzhang$ docker run -itd -P mysql:5.6 bash
a94fd445ca731e9c5251034db58f2e61cd245c8ddd31328a4099c695ebddd4af

4. 查看已经运行的docker镜像，可以看到mysql镜像的3306端口绑定了本地的32768端口，如果你要在本机中访问docker中的mysql数据库就需要使用localhost:32768来进行访问， hardcore_lichterman 是镜像的名字。

Michaels-MacBook-Pro-3:workspace-architect michaelzhang$ docker ps -a
CONTAINER ID        IMAGE                                             COMMAND                  CREATED             STATUS                       PORTS                     NAMES
a94fd445ca73        mysql:5.6                                         "docker-entrypoint.s…"   8 seconds ago       Up 15 seconds                0.0.0.0:32768->3306/tcp   hardcore_lichterman

5. 从本机连接到docker的mysql镜像中

docker exec 是docker镜像的连接命令，类似于ssh一样的命令，hardcore_lichterman是镜像的名字，镜像每次启动都必须有一个名字，该名字可以手动指定也可以自己生成。

Michaels-MacBook-Pro-3:workspace-architect michaelzhang$ docker exec -it hardcore_lichterman bash

No directory, logging in with HOME=/
...

6. 报错（No directory, logging in with HOME=/）没有找到mysql所在的目录，配置用户的登录目录即可，但是要先停mysql的服务

root@a94fd445ca73:/# service mysql stop

.....

[info] MySQL Community Server 5.6.46 is stopped.

root@a94fd445ca73:/# usermod -d /var/lib/mysql/ mysql

root@a94fd445ca73:/# service mysql start

..

[info] MySQL Community Server 5.6.46 is started.

7. 输入mysql 验证mysql是否启动成功

root@a94fd445ca73:/# mysql
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 1
Server version: 5.6.46 MySQL Community Server (GPL)

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

8. 查看所有的数据库， 到此为止，docker中的mysql已经启动成功。

mysql> show databases
    -> ;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| test               |
+--------------------+
4 rows in set (0.00 sec)

9. 如何在外部使用root连接这个mysql？   为了安全，首先需要设置root帐号的密码，先将当前库切到mysql

mysql> use mysql
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed

10. 设置root账户的密码为root

mysql> update user set authentication_string = password('root') where user = 'root';
Query OK, 4 rows affected (0.00 sec)
Rows matched: 4  Changed: 4  Warnings: 0

11. 给所有root用户赋权，外部的电脑也能够通过root访问Docker中的mysql数据库
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;
Query OK, 0 rows affected (0.00 sec)

mysql> 

12. 使用mysql的workbench从本机链接到docker中的mysql

链接成功，测试执行成功。
