本地制作mysql镜像并在docker中启动容器

柔光的暖阳◎ 2024-02-19 12:32 6阅读 0赞

docker相关命令：

docker ps：查看启动成功的容器

docker ps -a：查看所有启动的容器（包括启动异常的容器）

docker rm 容器id：删除容器

docker stop 停止容器

docker-compose：通过加载配置文件的方式启动容器

1、拉取mysql镜像，采用网易加速地址  
docker pull hub.c.163.com/library/mysql:5.7

2、重命名镜像名  
docker tag hub.c.163.com/library/mysql:5.7 mysql:5.7

3、创建文件备份目录

3.1、mkdir /Users/trusause/mysql/conf

3.2、mkdir /Users/trusause/mysql/logs

3.3、mkdir /Users/trusause/mysql/data/mysql

4、/Users/trusause/mysql/conf下新建my.cnf文件（5.7.18以后需要）

5、启动

方式一：通过docker命令启动

docker run -p 3306:3306 --name mysql:5.7 -v /Users/trusause/mysql/conf/my.cnf:/etc/mysql/my.cnf -v /Users/trusause/mysql/logs:/logs -v /Users/trusause/mysql/data/mysql:/var/lib/mysql -e MYSQL\_ROOT\_PASSWORD=password -d mysql:5.7

方式二：通过docker-compose命令加载配置文件启动

注意：一定需要加tty: true否则启动会报错：Exited (0) About a minute ago

启动失败是因为缺失了控制终端的配置，这里有两种方式修复：

1、增加一个配置tty: true

version: '2'
    services:
        mysql:
        image: mysql:5.7
        environment:
          MYSQL_ROOT_PASSWORD: "password"
        ports:
          - 3306:3306
        restart: always
        logging:
          options:
            max-size: "10m"
            max-file: "10"
        tty: true

2、使用exec重新创建容器（不推荐）  
这种方式并不推荐，因为这样做虽然可以启动容器，但是只能重新创建一个容器，具体方法如下：  
1. 使用docker-compose up -d命令启动后，由于没有tty:true的配置，容器就退出了；  
2. 这时候执行命令docker-compose run master /bin/bash，会创建一个容器，并且进入这个容器；  
3. 在当前电脑再打开一个控制台，执行docker ps命令，发现新建了一个容器，状态正常
