是什么
MinIO 是一个高性能的分布式对象存储服务,适合存储非结构化数据,如图片,音频,视频,日志等。对象文件最大可以达到5TB。
安装启动
mkdir -p /usr/local/minio
cd /usr/local/minio
# 下载安装包
wget https://dl.min.io/server/minio/release/linux-amd64/minio
下载完毕后:
在当前minio目录下,会出现一个minio文件
# 给予权限
chmod +x minio
# 创建minio文件存储目录及日志目录
mkdir -p /usr/local/minio/data
mkdir -p /usr/local/minio/logs
然后在 /usr/local/minio/目录下,新建一个run.sh并编辑以下内容
vim run.sh,然后将以下内容保存到run.sh,并为其赋予执行权限chmod u+x run.sh
run.sh内容如下:
#!/bin/bash
export MINIO_ACCESS_KEY=minio
export MINIO_SECRET_KEY=minio123456
# nohup启动服务 指定文件存放路径 /root/data 还有设置日志文件路径 /root/minio/log
nohup ./minio server --address :9000 --console-address :9001 /usr/local/minio/data > /usr/local/minio/logs/minio.log 2>&1 &
启动minIO
# 启动minio服务
./run.sh
# 查看日志
tail -f /usr/local/minio/logs/minio.log
平台使用
地址:http://127.0.0.1:9000(注意开放对应端口9000、9001)【当端口 9000
用于连接到 API 时,MinIO 会自动将浏览器访问重定向到 MinIO 控制台9001。】
输入账号密码后,
创建bucket,名字随意,创建完成后服务器/usr/local/minio/data下也会创建这个文件目录

SpringBoot集成MinIO
1.添加依赖
<dependency>
<groupId>io.minio</groupId>
<artifactId>minio</artifactId>
<version>8.4.1</version>
</dependency>
2.配置文件
spring:
minio:
endpoint: http://124.222.253.33:9000
access-key: minio
secret-key: minio123456
bucket-name: file
servlet:
multipart: # 上传文件最大大小
max-file-size: 1024MB
max-request-size: 1024MB
3.配置类创建客户端
@Data
@Component
@ConfigurationProperties(prefix = "spring.minio")
public class MinioConfig {
private String endpoint;
private String accessKey;
private String secretKey;
@Bean
public MinioClient minioClient() {
return MinioClient.builder()
.endpoint(endpoint)
.credentials(accessKey, secretKey)
.build();
}
}
4.核心业务类
