如何在 Windows 10 上挂载 Docker MySQL Data/Socket 卷？

Question

我正在尝试运行 docker mysql 上 windows 10 上的最新图像，并安装了主机上的数据目录。

我运行宁

docker run --rm --name=mysql --mount type=bind,src="C:\Docker Projects\mysql\mysql_data",dst=/var/lib/mysql mysql/mysql-server

但它抱怨套接字不存在。

2020-01-20T17:23:22.758269Z 0 [ERROR] [MY-010270] [Server] Can't start server : Bind on unix socket: Operation not permitted
2020-01-20T17:23:22.758416Z 0 [ERROR] [MY-010258] [Server] Do you already have another mysqld server running on socket: /var/lib/mysql/mysql.sock ?

我可以看到 mysql mysql.sock.lock 已创建。我还尝试从主机创建一个 mysql.sock 文件。

我想这是在告诉我，我需要为 windows https://dev.mysql.com/doc/refman/5.7/en/deploy-mysql-nonlinux-docker.html 指定套接字文件的位置，但我似乎无法正确理解命令语法？

Answer 1

你是对的。问题是 mysql.sock 文件被放入 /var/lib/mysql，它被挂载到不支持 Unix 域套接字的 Windows 主机系统目录。

启动服务器时只需使用开关 --socket=/tmp/mysql.sock。

Answer 2

如果您需要它来为 docker-compose 工作，您可以使用以下 docker-compose.yml 和 my.cnf 文件。

在 my.cnf 文件中，套接字位置从 socket=/var/lib/mysql/mysql.sock 更改为 socket=/tmp/mysql.sock。

docker-compose.yml

version: "3.7"
services:
  mysql:
    image: mysql/mysql-server:5.7.27
    volumes:
      - "./my.cnf:/etc/my.cnf"

my.cnf
