這篇文章主要介紹了docker安裝minio及實現(xiàn)文件上傳、刪除、下載方式，具有很好的參考價值，希望對大家有所幫助。如有錯誤或未考慮完全的地方，望不吝賜教

docker安裝minio及文件上傳、刪除、下載

要搭建一個分布式文件存儲系統(tǒng)，聽說fastDFS能實現(xiàn)，于是我搜了一下fastDFS，結(jié)果半路殺出一個minio

考慮到拓展性、開發(fā)api文檔完善度、部署效率等原因我選擇了minio。

因為個人沒真正使用過fastDFS，所以不作過多評價，占個坑，以后有機會深度體驗后回來寫評測。

1. docker安裝minio步驟

第一步查鏡像

docker search minio

第二步拉鏡像

docker pull minio/minio

第三步啟動容器

docker run -p 9000:9000 --name minio
-d --restart=always
-e “MINIO_ACCESS_KEY=admin”
-e “MINIO_SECRET_KEY=admin123456”
-v /home/data:/data
-v /home/config:/root/.minio
minio/minio server /data

第四步登錄界面

http//:ip+9000
ACCESS_KEY:damin
SECRET_KEY:admin123456

2. minio實現(xiàn)文件上傳、刪除、下載

項目結(jié)構(gòu)

pom依賴：

<dependencies>
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
            <version>2.1.0.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>io.minio</groupId>
            <artifactId>minio</artifactId>
            <version>3.0.10</version>
        </dependency>
    </dependencies>

啟動類：

@SpringBootApplication
@EnableDiscoveryClient
public class CfUploadApplication {
    public static void main(String[] args) {
        SpringApplication.run(CfUploadApplication.class,args);
    }
}

yml配置文件：

server:
  port: 8002
spring:
  application:
    name: upload-service
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848
  servlet:
    multipart:
      enabled: true #開啟文件上傳
      max-file-size: 500MB
      max-request-size: 500MB
minio:
  endpoint: http://localhost:9000 #Minio服務(wù)所在地址
  bucketName: cheung #存儲桶名稱
  accessKey: admin #訪問的key
  secretKey: admin123456 #訪問的秘鑰

logging:
  level:
    com.heima: debug

            byte buf[] = new byte[1024];
            int length = 0;
            httpResponse.reset();

            httpResponse.setHeader("Content-Disposition", "attachment;filename=" + URLEncoder.encode(filename, "UTF-8"));
            httpResponse.setContentType("application/octet-stream");
