1.3、docker-compose.yml

version: '3'
services:
  # 指定服务名称
  db:
    # 指定服务使用的镜像
    image: mysql:5.7
    # 指定容器名称
    container_name: mysql
    # 指定服务运行的端口
    ports:
      - 3306:3306
    # 指定容器中需要挂载的文件
    volumes:
      - /mydata/mysql/log:/var/log/mysql
      - /mydata/mysql/data:/var/lib/mysql
      - /mydata/mysql/conf:/etc/mysql
    # 指定容器的环境变量

2、Linux环境准备

2.1、下载Docker

yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum install docker-ce
systemctl start docker

2.2、配置并启动Dokcer

• 修改docker.service

docker run -d -p 5000:5000 --restart=always --name registry2 registry:2
vi /usr/lib/systemd/system/docker.service
修改的部分：ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock

• 支持HTTP上传镜像

echo '{ "insecure-registries":["106.55.226.70:5000"] }'>/etc/docker/daemon.json
systemctl daemon-reload
systemctl stop docker
systemctl start docker

3、启动服务

3.1、启动MySQL服务

• 运行MySQL并进入容器内部

docker run -p 3306:3306 --name mysql \
-v /mydata/mysql/log:/var/log/mysql \
-v /mydata/mysql/data:/var/lib/mysql \
-v /mydata/mysql/conf:/etc/mysql \
-e MYSQL_ROOT_PASSWORD=root  \
-d mysql:5.7
docker exec -it mysql /bin/bash

• 让MySQL支持远程连接

mysql -uroot -proot
grant all privileges on *.* to 'root'@'%';

• 导入SQL文件

create database mall character set utf8;
window连接导入sql

3.2、Docker-compose配置

• 下载Docker-compose并设置文件权限，通过查看版本来验证安装成功了吗？

curl -L https://get.daocloud.io/docker/compose/releases/download/1.24.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
docker-compose --version

• Lifecycle>package,打包成镜像上传Docker

• 将docker-compose.yml上传至Linux服务器

• 运行Docker Compose命令启动所有服务

docker-compose up -d
