2. 在/usr/local/bin目录下查看docker-compose,然后给docker-compose加一个可执行的权限:
   chmod +x docker -compose
3. 查看是否安装完成:docker-compose version
4. 在/usr/local/下创建docker目录,然后在docker目录下创建tomcat目录,然后在tomcat目录下创建docker-compose.yml,然后写入代码:

services:
  nexus:
    restart: always
    image: sonatype/nexus3
    container_name: nexus
    ports:
      - 8081:8081
    volumes:
      - /usr/local/docker/nexus/data:/nexus-data

5. 然后执行docker-compose up
6. 利用docker-compose部署项目,在/usr/local/docker/tomcat下创建docker-compose.yml
7. 启动docker-compose up
8. 把项目上传到/usr/local/docker/myshop/ROOT下
9. 把项目的数据源配置改正确
