如何从主机连接到运行在 Docker 上的 MySQL

How to connect to MySQL running on Docker from the host machine(如何从主机连接到运行在 Docker 上的 MySQL)

问题描述

我已经用谷歌搜索过这个主题，但发现的主题很少.基于这些线程，我遵循了以下步骤.但是我遇到了一个问题.

I have already googled on this subject and found few threads. Based on these threads I have followed the following steps. But I am facing a problem.

基本上，我想为 mysql 创建一个 docker 镜像，然后从我的主机 (Mac OS X) 连接到它.

Basically, I want to create a docker image for mysql and then connect to it from my host machine (Mac OS X).

基于这篇帖子，我必须与主机共享 mysql unix 套接字.为此我做了以下步骤

Based on this post , I have to share the mysql unix socket with the host. towards this I have done the following steps

1. Start docker quick terminal
2. docker run --name mysql -e MYSQL_ROOT_PASSWORD=password -d mysql/mysql-server:latest
3. docker exec -it mysql bash
4. mysql -uroot -p
5. create database MyDB;
6. GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'password';
7. exit;
8. mkdir /Users/abhi/host
9. docker run -it -v /host:/shared mysql/mysql-server:latest

现在我收到错误

MacBook-Pro:~$ docker run -it -v /Users/abhi/host:/shared mysql/mysql-server
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

但是你看到我已经提供了密码并初始化了我的数据库.

But you see that I have provided the password and initialized my database.

我想要的是从我的主机，我可以连接到在 docker 中运行的 mysql 数据库.

All I want is that from my host machine, I can connect to the mysql database running inside docker.

谢谢里科.最后对我有用的步骤是

Thanks RICO. Finally the steps which worked for me are

1. Start docker quick terminal
2. docker run --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=password -d mysql/mysql-server:latest
3. docker exec -it mysql bash
4. mysql -uroot -p
5. create database MyDB;

  or:
  CREATE USER 'root'@'%' IDENTIFIED BY 'root';
  GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;

6. GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'password';
7. exit;
8. docker-machine env default

使用步骤8获取的IP地址，端口为3306，用户为root，密码为password，数据库为MyDB.

Use the IP address obtained in step 8. port is 3306, user is root, password is password, database is MyDB.

连接成功！

推荐答案

所以你基本上需要将 mysql 端口暴露给你的主机:

So you basically you need to expose the mysql port to your host:

docker run --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=password -d mysql/mysql-server:latest

然后您可以使用mysql命令行从您的主机访问:

Then you can access from your host using the mysql command line:

mysql -h127.0.0.1 -ppassword -uroot

不确定为什么要尝试运行另一个容器来连接(也许您的意思是链接两个容器)

Not sure why you are trying to run another container to connect (perhaps you meant linking two containers)

如果您使用 Mac(或 Windows)和 docker-machine，您希望连接到您的 docker-machine 虚拟机的 IP 地址.例如:

If you are using Mac (or Windows) with docker-machine you want to connect to the IP address of your docker-machine VM. For example:

$ docker-machine ssh default
                        ##         .
                  ## ## ##        ==
               ## ## ## ## ##    ===
           /"""""""""""""""""\___/ ===
      ~~~ {~~ ~~~~ ~~~ ~~~~ ~~~ ~ /  ===- ~~~
           \______ o           __/
                          __/
              \____\_______/
 _                 _   ____     _            _
