DockerCompose+SpringBoot+Nginx+Mysql实践
1、Spring Boot案例
首先我们先准备一个 Spring Boot 使用 Mysql 的小场景，我们做这样一个示例，使用 Spring Boot 做一个 Web 应
用，提供一个按照 IP 地址统计访问次数的方法，每次请求时将统计数据存入 Mysql 并展示到页面中。
1.1 pom依赖
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.neo</groupId><artifactId>dockercompose-springboot-mysql-nginx</artifactId><version>1.0</version><packaging>jar</packaging><name>dockercompose-springboot-mysql-nginx</name><description>Demo project for Spring Boot</description><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.0.0.RELEASE</version></parent><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><java.version>1.8</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-jpa</artifactId></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency></dependencies><build><defaultGoal>compile</defaultGoal><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>
主要添加了 Spring Boot Web 支持，使用 Jpa 操作数据库、添加 Myql 驱动包等。
1.2 配置文件
application.properties
spring.jpa.properties.hibernate.hbm2ddl.auto=update
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
spring.jpa.show-sql=truespring.profiles.active=dev
server.port=8090
application-dev.properties
spring.datasource.url=jdbc:mysql://localhost:3306/test
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
server.port=8090
application-docker.properties
spring.datasource.url=jdbc:mysql://mysql:3306/test
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
server.port=8090
配置了数据库的链接信息，以及 Jpa 更新表模式、方言和是否显示Sql。
1.3 核心代码
核心代码很简单，每过来一个请求，判断是否已经统计过，如果没有统计新增数据，如果有统计数据更新数据。
package com.neo.controller;import com.neo.entity.Visitor;
import com.neo.repository.VisitorRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;import javax.servlet.http.HttpServletRequest;@RestController
public class VisitorController {@Autowiredprivate VisitorRepository repository;@RequestMapping("/")public String index(HttpServletRequest request) {String ip = request.getRemoteAddr();Visitor visitor = repository.findByIp(ip);if (visitor == null) {visitor = new Visitor();visitor.setIp(ip);visitor.setTimes(1);} else {visitor.setTimes(visitor.getTimes() + 1);}repository.save(visitor);return "I have been seen ip " + visitor.getIp() + " " + visitor.getTimes() + " times.";}
}
实体类和 Repository 层代码比较简单。
package com.neo.entity;import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;@Entity
public class Visitor {@Id@GeneratedValueprivate long id;@Column(nullable = false)private long times;@Column(nullable = false)private String ip;public long getId() {return id;}public void setId(long id) {this.id = id;}public long getTimes() {return times;}public void setTimes(long times) {this.times = times;}public String getIp() {return ip;}public void setIp(String ip) {this.ip = ip;}
}
package com.neo.repository;import com.neo.entity.Visitor;
import org.springframework.data.jpa.repository.JpaRepository;public interface VisitorRepository extends JpaRepository<Visitor, Long> {Visitor findByIp(String ip);
}
package com.neo;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication
public class ComposeApplication {public static void main(String[] args) {SpringApplication.run(ComposeApplication.class, args);}
}
以上内容都完成后，启动项目，访问：http://localhost:8090/ 我们就可以看到这样的返回结果：
I have been seen ip 0:0:0:0:0:0:0:1 1 times.
再访问一次会变成
I have been seen ip 0:0:0:0:0:0:0:1 2 times.
多次访问一直叠加，说明演示项目开发完成。
2、Docker化改造
首先我们将目录改造成这样一个结构
我们先从最外层说起：
-
docker-compose.yaml：docker-compose 的核心文件，描述如何构建整个服务。 -
nginx：有关 nginx 的配置。 -
app：Spring Boot 项目地址。
如果我们需要对 Mysql 有特殊的定制，也可以在最外层创建 mysql 文件夹，在此目录下进行配置。
2.1 docker-compose.yaml 文件详解
version: '3'
services:nginx:container_name: v-nginximage: nginx:1.13restart: alwaysports:- 80:80- 443:443volumes:- ./nginx/conf.d:/etc/nginx/conf.dmysql:container_name: v-mysqlimage: mysql/mysql-server:5.7environment:MYSQL_DATABASE: testMYSQL_ROOT_PASSWORD: rootMYSQL_ROOT_HOST: '%'ports:- "3306:3306"restart: alwaysapp:container_name: apprestart: alwaysbuild: ./appworking_dir: /appvolumes:- ./app:/app- /home/zhangshixing/maven/m2:/root/.m2expose:- "8090"depends_on:- nginx- mysqlcommand: mvn clean spring-boot:run -Dspring-boot.run.profiles=docker
-
version: '3'： 表示使用第三代语法来构建 docker-compose.yaml 文件。 -
services：用来表示 compose 需要启动的服务，我们可以看出此文件中有三个服务分别为：nginx、mysql、app。
-
container_name：容器名称 -
environment：此节点下的信息会当作环境变量传入容器，此示例中 mysql 服务配置了数据库、密码和权限信息。
-
ports：表示对外开放的端口 -
restart: always：表示如果服务启动不成功会一直尝试。 -
volumes：加载本地目录下的配置文件到容器目标地址下 -
depends_on：可以配置依赖服务，表示需要先启动 depends_on 下面的服务后，再启动本服务。 -
command: mvn clean spring-boot:run -Dspring-boot.run.profiles=docker：表示以这个命令来启动项目，
-Dspring-boot.run.profiles=docker表示使用application-docker.properties文件配置信息进行启动。
2.2 Nginx 文件解读
nginx 在目录下有一个文件 app.conf，主要配置了服务转发信息。
server {listen 80;charset utf-8;access_log off;location / {proxy_pass http://app:8090;proxy_set_header Host $host:$server_port;proxy_set_header X-Forwarded-Host $server_name;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;}location /static {access_log off;expires 30d;alias /app/static;}
}
这块内容比较简单，配置请求转发，将80端口的请求转发到服务 app 的8090端口。其中proxy_pass
http://app:8090这块的配置信息。
需要解释一下，这里使用是app而不是localhost，是因为他们没有在一个容器中，在一组 compose 的服务通
讯需要使用 services 的名称进行访问。
2.3 Spring Boot 项目改造
在app目录下也就是和pom.xm文件同级添加Dockerfile文件，文件内容如下：
FROM maven:3.5-jdk-8
只有一句，依赖于基础镜像maven3.5和jdk1.8。因为在docker-compose.yaml文件设置了项目启动命令，这
里不需要再添加启动命令。
在项目的resources目录下创建application-dev.properties和application-docker.properties文件
-
application-dev.properties中的配置信息和上面一致 -
application-docker.properties中的配置信息做稍微的改造，将数据库的连接信息由jdbc:mysql://localhost:3306/test改为jdbc:mysql://mysql:3306/test。
这样我们所有的配置都已经完成。
2.4 部署
我们将项目拷贝到服务器中进行测试，服务器需要先安装 Docker 和 Docker Compos 环境。
将项目拷贝到服务器中，进入目录：cd dockercompose-springboot-mysql-nginx
启动服务：docker-compose up
[root@zsx dockercompose-springboot-mysql-nginx]# docker-compose up

看到信息Tomcat initialized with port(s): 8090 (http)表示服务启动成功。
也可以使用docker-compose up -d后台启动：
[root@zsx dockercompose-springboot-mysql-nginx]# docker-compose up -d
[+] Running 3/3⠿ Container v-nginx Started 0.8s⠿ Container v-mysql Started 0.7s⠿ Container app Started 1.6s
访问服务器地址：http://192.168.136.195/，返回：I have been seen ip 172.19.0.2 1 times.
表示整体服务启动成功。
使用docker-compose ps查看项目中目前的所有容器：
[root@zsx dockercompose-springboot-mysql-nginx]# docker ps

可以看到项目中服务的状态、命令、端口等信息。
关闭服务docker-compose down：
[root@zsx dockercompose-springboot-mysql-nginx]# docker-compose down

2.5 docker-compose 顺序
在使用 docker-compose 启动的时候经常会出现项目报 Mysql 连接异常，跟踪了一天终于发现了问题。 docker-
compose 虽然可以通过depends_on 来定义服务启动的顺序，但是无法确定服务是否启动完成，因此会出现这
样一个现象，Mysql 服务启动比较慢，当 Spring Boot 项目已经启动起来，但是 Mysql 还没有初始化好，这样当
项目连接 Mysql 数据库的时候，就会出现连接数据库的异常。
针对这样的问题，有两种解决方案:
1、足够的容错和重试机制，比如连接数据库，在初次连接不上的时候，服务消费者可以不断重试，直到连接上服
务。也就是在服务中定义： restart: always
2、同步等待，使用wait-for-it.sh或者其他shell脚本将当前服务启动阻塞，直到被依赖的服务加载完毕。这
种方案后期可以尝试使用。
3、总结
没有对比就没有伤害，在没有使用 Docker 之前，我们需要搭建这样一个环境的话，需要安装 Nginx、Mysql ，再
进行一系列的配置调试，还要担心各种环境问题；使用 Docker 之后简单两个命令就完成服务的上线、下线。
# 初始化并启动容器
$ docker-compose up
# 停止容器并且删除容器
$ docker-compose down
# 停止容器
$ docker-compose stop
# 启动容器
$ docker-compose start
其实容器技术对部署运维的优化还有很多，这只是刚刚开始，后面使用了 Swarm 才会真正感受到它的便利和强
大。
