mysql挂载在Docker的volume中

1.第一步:

 1 docker volume create mysql-data 

2.第二步:

 创建一个mysql文件夹

3.第三步:

 再mysql文件夹下创建docker-compose.yml

因最新版docker已不支持/g/的绝对路径表达方式，改为./的相对路径【以docker-compose.yml的相对路径】)

 1 version: ‘3‘
 2 services:
 3   db:
 4     image: mysql/mysql-server
 5     container_name: db-mysql
 6     restart: always
 7     command: mysqld --character-set-server=utf8 --collation-server=utf8_general_ci
 8     ports:
 9       - "3306:3306"  
10     networks:
11       - net_db
12     environment:
13       MYSQL_ROOT_PASSWORD: pwd123456
14     volumes: 
15       - mysql-data:/var/lib/mysql
16 volumes:
17   mysql-data:
18     external: true
19 networks:
20   net_db:
21     external: true

4.第四步:

docker-compose up

5.第五步:

登陆:  1 docker exec -it db-mysql bash 2 3 mysql -uroot -p 4 pwd123456 

如果出现

Access denied for user ‘root‘@‘localhost‘ (using password : YES)

请继续看:

删除镜像:

列出所有images: 

docker images

docker rmi   IMAGE ID

删除volume

1  列出所有volume: 
2 docker volume ls

  docker volume rm mysql-data

删除mysql文件夹

 

 重复上面的操作把第四不的命令加上db

1 docker-compose up db

 

 1 C:\Users\GYW>docker exec -it db-mysql bash
 2 bash-4.2# mysql -uroot -p
 3 Enter password:
 4 Welcome to the MySQL monitor.  Commands end with ; or \g.
 5 Your MySQL connection id is 18
