一、Linux 安装Minio
安装
在/root/xxkfz/soft目录下面创建文件minio文件夹，进入minio文件夹，并创建data目录；
[root@xxkfz soft]# mkdir minio
[root@xxkfz soft]# cd minio
[root@xxkfz minio]# mkdir data执行如下命令进行下载
[root@xxkfz minio]# wget https://dl.min.io/server/minio/release/linux-amd64/minio
[root@xxkfz minio]# chmod +x minio # 赋权下载完成后如下所示：
设置账号密码
minio 默认账号密码为 minioadmin/minioadmin
[root@xxkfz minio]# export MINIO_ACCESS_KEY=admin # 设置控制台账号（最少3位）
[root@xxkfz minio]# export MINIO_SECRET_KEY=12345678 # 设置密码（最少8位）直接设置管理员账号密码 编辑 /etc/profile 文件即可
[root@xxkfz minio]# vim /etc/profile编辑/etc/profile文件，追加如下内容：
#===============================Minio=============================================
# set minio environment
export MINIO_ROOT_USER=admin
export MINIO_ROOT_PASSWORD=admin123可省略 设置账号密码 此步骤！12
启动
进入执行文件目录/root/xxkfz/soft/minio，自定义端口启动（默认端口：9000）
[root@xxkfz minio]# nohup /root/xxkfz/soft/minio/minio server --address :9001 --console-address :9002 /root/xxkfz/soft/minio/data >/root/xxkfz/soft/minio/minio.log 2>&1 &说明：
•nohup 为后台启动•./minio server 启动命令•--address :9001 指定API端口•--console-address :9002 指定控制台端口•/usr/local/minio/data 指定存储目录•>/usr/local/minio/minio.log 2>&1 控制台日志重定向到/usr/local/minio/minio.log文件中•& 后台运行
启动成功：
启动成功
启动成功
注意：浏览器访问需要开启防火墙端口！
阿里云配置开放9001、9002端口
测试访问：http://IP地址:9002
输入账号密码： admin/12345678 登录成功!
设置开机自启动
设置Minio服务器宕机后自动重启
进入init.d目录
[root@xxkfz minio]# cd /etc/rc.d/init.d新建minio.sh shell脚本文件
[root@xxkfz init.d]# vim minio.sh shell脚本内容
#!/bin/bash
#chkconfig: 2345 10 90
#description: ping10
nohup /root/xxkfz/soft/minio/minio server --address :9001 --console-address :9002 /root/xxkfz/soft/minio/data >/root/xxkfz/soft/minio/minio.log 2>&1 &给shell脚本赋权
chmod +x minio.sh添加到开机自启动服务中
chkconfig --add minio.sh设置开机自启动
chkconfig minio.sh on查看是否添加成功
chkconfig --list
二、Spring Boot整合Minio

}项目启动初始化配置
创建配置类InitConfig.java，并实现了InitializingBean接口，重写afterPropertiesSet方法。
该方法主要实现逻辑：在项目启动的时候初始化Bucket，如果没有则进行创建！
InitConfig.java
/*** @program: xxkfz-minio* @ClassName Init.java* @author: wust* @create: 2024-03-16 10:34* @description: 项目启动初始化配置**/
@Component
@Slf4jpublic class InitConfig implements InitializingBean {@Autowiredprivate MinioUtils minioUtils;@Autowiredprivate MinioConfig minioConfig;@Overridepublic void afterPropertiesSet() throws Exception {// 项目启动创建Bucket，不存在则进行创建minioUtils.createBucket(minioConfig.getBucketName());}
}编写测试接口
MinioController.java
/*** @program: xxkfz-minio* @ClassName OSSController.java* @author: wust* @create: 2024-03-13 11:01* @description:**/

}测试验证
启动项目：

进入服务器查看文件上传情况。
进入目录：/root/xxkfz/soft/minio/data/xk-admin
当然，也可以直接访问minio的地址：http://IP地址:9001/xk-admin/1710558001536.jpg。验证文件是否上传成功。
获取文件信息
测试接口：http://localhost:8099/oss/info
获取文件外链
