Compse编排微服务实战
2022-08-01 19:13:00 【小码哥呀】
1、改造升级微服务工程spring_docker
1.1、mysql中建库建表
t_user表建表语句
CREATE TABLE `t_user` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`username` varchar(50) NOT NULL DEFAULT '' COMMENT '用户名',
`password` varchar(50) NOT NULL DEFAULT '' COMMENT '密码',
`sex` tinyint(4) NOT NULL DEFAULT '0' COMMENT '性别 0=女 1=男 ',
`deleted` tinyint(4) unsigned NOT NULL DEFAULT '0' COMMENT '删除标志，默认0不删除，1删除',
`update_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
`create_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 COMMENT='用户表'
1.2、修改pom文件
<?xml version="1.0" encoding="UTF-8"?>

1.3、编写yml配置文件
- 注意修改redis、mysql密码为自己的
server.port=6001
# ========================alibaba.druid相关配置=====================
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://192.168.126.129:3306/mybatis_plus?useUnicode=true&characterEncoding=utf-8&useSSL=false
spring.datasource.username=xxxxxx
spring.datasource.password=xxxxxx

# ========================redis相关配置=====================
spring.redis.database=0

spring.redis.port=6379
spring.redis.password=xxxxxx
spring.redis.lettuce.pool.max-active=8
spring.redis.lettuce.pool.max-wait=-1ms
spring.redis.lettuce.pool.max-idle=8
spring.redis.lettuce.pool.min-idle=0
# ========================mybatis相关配置===================
mybatis.mapper-locations=classpath:mapper/*.xml
mybatis.type-aliases-package=com.project.test.entity
# ========================swagger=====================
spring.swagger2.enabled=true
1.4、主启动类
package com.project.test;
import tk.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* Description:
* DATE: 2022/7/30 15:28
*/
@SpringBootApplication
@MapperScan("com.java.test.mapper") //import tk.mybatis.spring.annotation.MapperScan;
public class CloudBootApplication {
public static void main(String[] args) {
SpringApplication.run(CloudBootApplication.class,args);
}
}
1.5、业务类
1.5.1、configure配置类

*/
@Bean
public RedisTemplate<String,Serializable> redisTemplate(LettuceConnectionFactory lettuceConnectionFactory)
{

1.5.3、mapper
- mapper
package com.project.test.mapper;
import com.project.test.entity.User;
import tk.mybatis.mapper.common.Mapper;
/**
* Description:
* DATE: 2022/7/31 9:29
*/
public interface UserMapper extends Mapper<User> {
}
- src\main\resources路径下新建mapper文件夹并新增UserMapper.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

</mapper>
1.5.4、service

import lombok.extern.slf4j.Slf4j;
import org.springframework.data.redis.core.RedisTemplate;

//2 需要再次查询一下mysql将数据捞回来并ok

//3 将捞出来的user存进redis，完成新增功能的数据一致性。
String key = CACHE_KEY_USER+user.getId();

//3.1 redis+mysql 都无数据
//你具体细化，防止多次穿透，我们规定，记录下导致穿透的这个key回写redis
return user;
}else{
//3.2 mysql有，需要将数据写回redis，保证下一次的缓存命中率
redisTemplate.opsForValue().set(key,user);
}
}
return user;
}
}
1.5.5、controller
package com.project.test.controller;
import cn.hutool.core.util.IdUtil;
import com.project.test.entity.User;
import com.project.test.service.UserService;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;

// BeanUtils.copyProperties(userDTO,user);
// userService.updateUser(user);
// }
}
1.6、微服务打包并上传中服务器指定位置
- 打包
- 上传
1.7、编写Dockefile文件
# 基础镜像使用java
FROM java:8
# 作者
MAINTAINER csf
# VOLUME 指定临时文件目录为/tmp，在主机/var/lib/docker目录下创建了一个临时文件并链接到容器的/tmp
VOLUME /tmp
# 将jar包添加到容器中并更名为zzyy_docker.jar
ADD spring_boot-0.0.1-SNAPSHOT.jar csf_docker.jar
# 运行jar包
RUN bash -c 'touch /csf_docker.jar'
ENTRYPOINT ["java","-jar","/csf_docker.jar"]
#暴露6001端口作为微服务
EXPOSE 6001
1.8、构建镜像
#构建镜像
docker build -t csf_docker:1.6 .
# 启动镜像
docker run -d -p 6001:6001 csf_docker:1.6
2、不使用Compose
2.1、启动单独的mysql容器实例
- 新建mysql容器实例
注意mysql修改密码为自己的
docker run -p 3306:3306 --name mysql57 --privileged=true -v /zzyyuse/mysql/conf:/etc/mysql/conf.d -v /zzyyuse/mysql/logs:/logs -v /zzyyuse/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=xxxx -d mysql:5.7
- 进入mysql容器实例并新建库db2021新建表t_user
docker exec -it mysql57 /bin/bash
mysql -uroot -p
create database db2021;
use db2021;
CREATE TABLE `t_user` (
`id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
`username` VARCHAR(50) NOT NULL DEFAULT '' COMMENT '用户名',
`password` VARCHAR(50) NOT NULL DEFAULT '' COMMENT '密码',
`sex` TINYINT(4) NOT NULL DEFAULT '0' COMMENT '性别 0=女 1=男 ',
`deleted` TINYINT(4) UNSIGNED NOT NULL DEFAULT '0' COMMENT '删除标志，默认0不删除，1删除',
`update_time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
`create_time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
PRIMARY KEY (`id`)
) ENGINE=INNODB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8mb4 COMMENT='用户表';
2.2、启动单独的redis容器实例
docker run -p 6379:6379 --name redis --privileged=true -v /app/redis/redis.conf:/etc/redis/redis.conf -v /app/redis/data:/data -d redis:6.0.8 redis-server /etc/redis/redis.conf
2.3、启动微服务工程
docker run -d -p 6001:6001 csf_docker:1.6
2.4、swagger测试
http://localhost:你的微服务端口/swagger-ui.html# /
- 在linux虚拟机中访问
- 在物理机上访问
2.5、存在的问题
3、使用Compose
3.1、编写docker-compose.yml文件
注意修改redis和mysql为自己的
version: "3"
services:
microService:
image: csf_docker:1.6
container_name: ms01
ports:
- "6001:6001"
volumes:
- /app/microService:/data
networks:
- csf_net
depends_on:
- redis
- mysql
redis:
image: redis:6.0.8
ports:
- "6379:6379"
volumes:
- /app/redis/redis.conf:/etc/redis/redis.conf
- /app/redis/data:/data
networks:
- csf_net
command: redis-server /etc/redis/redis.conf
mysql:
image: mysql:5.7
environment:
MYSQL_ROOT_PASSWORD: 'xxxxxx'
MYSQL_ALLOW_EMPTY_PASSWORD: 'no'
MYSQL_DATABASE: 'db2021'
MYSQL_USER: 'xxxxxx'
MYSQL_PASSWORD: 'xxxxxx'
ports:
- "3306:3306"
volumes:
- /app/mysql/db:/var/lib/mysql
- /app/mysql/conf/my.cnf:/etc/my.cnf
- /app/mysql/init:/docker-entrypoint-initdb.d
networks:
- csf_net
command: --default-authentication-plugin=mysql_native_password #解决外部无法访问
networks:
csf_net:
3.2、 第二次修改微服务工程spring_cloud
# 基础镜像使用java

# 作者

# VOLUME 指定临时文件目录为/tmp，在主机/var/lib/docker目录下创建了一个临时文件并链接到容器的/tmp

use db2021;
CREATE TABLE `t_user` (
`id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
`username` VARCHAR(50) NOT NULL DEFAULT '' COMMENT '用户名',
`password` VARCHAR(50) NOT NULL DEFAULT '' COMMENT '密码',
`sex` TINYINT(4) NOT NULL DEFAULT '0' COMMENT '性别 0=女 1=男 ',
`deleted` TINYINT(4) UNSIGNED NOT NULL DEFAULT '0' COMMENT '删除标志，默认0不删除，1删除',
`update_time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT '更新时间',
`create_time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '创建时间',
PRIMARY KEY (`id`)
) ENGINE=INNODB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8mb4 COMMENT='用户表';
3.5、Compose常用命令
Compose常用命令
docker-compose -h # 查看帮助
docker-compose up # 启动所有docker-compose服务
docker-compose up -d # 启动所有docker-compose服务并后台运行
docker-compose down # 停止并删除容器、网络、卷、镜像。
docker-compose exec yml里面的服务id # 进入容器实例内部 docker-compose exec docker-compose.yml文件中写的服务id /bin/bash
docker-compose ps # 展示当前docker-compose编排过的运行的所有容器
docker-compose top # 展示当前docker-compose编排过的容器进程
docker-compose logs yml里面的服务id # 查看容器输出日志
dokcer-compose config # 检查配置
dokcer-compose config -q # 检查配置，有问题才有输出
docker-compose restart # 重启服务
docker-compose start # 启动服务
docker-compose stop # 停止服务
