1、安装Docker

#1.需要的安装包
yum install -y yum-utils#2.设置镜像的仓库
yum-config-manager \--add-repo \http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo #使用阿里云仓库#更新yum软件包索引
yum makecache fast#3.安装docker相关的内容
yum install docker-ce docker-ce-cli containerd.io#4.启动docker
systemctl start docker#5.查看当前docker版本
docker version

2、安装Docker-Compose

#1、下载
sudo curl -L "https://github.com/docker/compose/releases/download/1.26.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose# 这个可能快点&＃xff01;
curl -L https://get.daocloud.io/docker/compose/releases/download/1.25.5/docker-compose-&＃96;uname -s&＃96;-&＃96;uname -m&＃96; > /usr/local/bin/docker-compose#2、授权
sudo chmod &＃43;x /usr/local/bin/docker-compose

3、部署SpringBoot &＃43; MySQL

1、创建SpringBoot项目&＃xff0c;导入以下依赖

• org.springframework.bootspring-boot-starter-weborg.springframework.bootspring-boot-starter-testtestorg.mybatis.spring.bootmybatis-spring-boot-starter2.2.2com.alibabafastjson1.2.76mysqlmysql-connector-java5.1.48org.projectlomboklombok


2、搭建基础环境架构

【实体类】

• /*** &＃64;Author 嘉宾* &＃64;Data 2022/3/21 14:54* &＃64;Version 1.0*/
&＃64;Data
&＃64;AllArgsConstructor
&＃64;NoArgsConstructor
public class Person {private Integer pid;private String pname;private Integer psex;
}

【接口】

• /*** &＃64;Author 嘉宾* &＃64;Data 2022/3/21 14:55* &＃64;Version 1.0*/
&＃64;Mapper
public interface PersonMapper {/*** 查询全部信息*/List findAll();
}

【mapper映射】

• 

select * from person

【service】

• /*** &＃64;Author 嘉宾* &＃64;Data 2022/3/21 14:57* &＃64;Version 1.0*/
public interface PersonService {/*** 查询全部信息*/List findAll();
}

【impl】

• /*** &＃64;Author 嘉宾* &＃64;Data 2022/3/21 14:57* &＃64;Version 1.0*/
&＃64;Service
public class PersonServiceImpl implements PersonService {&＃64;Autowiredprivate PersonMapper personMapper;&＃64;Overridepublic List findAll() {return personMapper.findAll();}
}

【controller】

• /*** &＃64;Author 嘉宾* &＃64;Data 2022/3/21 14:58* &＃64;Version 1.0*/
&＃64;RestController
&＃64;RequestMapping("/person")
public class PersonController {&＃64;Autowiredprivate PersonService personService;&＃64;GetMapping("/findAll")public String findAll(){List personList &＃61; personService.findAll();return personList.toString();}&＃64;GetMapping("/hello")public String hello(){return "

  Hello.JiaBin!";}
}

【配置文件】

• spring.datasource.driver-class-name&＃61;com.mysql.jdbc.Driver
#这里填写服务名即可mysqldbserver&＃xff0c;无需端口号
spring.datasource.url&＃61;jdbc:mysql://mysqldbserver:3306/sys?useUnicode&＃61;true&characterEncoding&＃61;utf-8&useSSL&＃61;false
spring.datasource.username&＃61;root
spring.datasource.password&＃61;123456mybatis.mapper-locations&＃61;classpath:mapper/*.xml
mybatis.type-aliases-package&＃61;com.jiabin.pojo

3、Dockerfile1

• FROM java:8VOLUME /vol/developmentRUN mkdir -p /vol/developmentWORKDIR /vol/developmentCOPY 这里需要改为自己的jar包.jar /vol/development/app.jarCMD ["java", "-Xmx200m", "-Djava.security.egd&＃61;file:/dev/./urandom","-jar","/vol/development/app.jar"]

4、Dockerfile

• FROM mysql:5.7.17

5、docker-compose.yml

• version : &＃39;3&＃39;
services:#sql服务mysqldbserver:#服务名称container_name: mysqldbserver#镜像image: mysql:5.7.17build:context: .dockerfile: Dockerfile#端口ports:- "3306:3306"command: [ #执行多条指令&＃39;mysqld&＃39;,&＃39;--innodb-buffer-pool-size&＃61;20M&＃39;,&＃39;--character-set-server&＃61;utf8&＃39;,&＃39;--collation-server&＃61;utf8_general_ci&＃39;,&＃39;--default-time-zone&＃61;&＃43;8:00&＃39;,&＃39;--lower-case-table-names&＃61;1&＃39;]environment:# 数据库MYSQL_DATABASE: sys# 设置root用户密码MYSQL_ROOT_PASSWORD: 123456#spring服务springappserver:# 服务名称container_name: springappserverbuild:context: .dockerfile: Dockerfile1ports: #端口- "8080:8080"volumes: #数据卷- /vol/developmentdepends_on:- mysqldbserverlinks: #连接sql- mysqldbserver

6、将项目打包以及上述三个配置文件统一上传到我们的服务器

7、使用命令docker-compose up部署&＃xff0c;通过ip&＃43;端口号访问项目即可&＃xff01;
