minio使用案例(Springboot)

一.minio文件服务搭建

 非docker环境部署(Linux部署)

1.官网下载安装包：MinIO | Code and downloads to create high performance object storage

 上传安装包文件到目录(这个可以自由选择)

/home/minio/

并创建data文件夹与在data下创建minio.log文件

 

2. 添加操作权限

chmod +x minio

用户名跟密码非必需执行的代码,如果不需要可以直接执行第3步.

# 自定义设置用户名(默认minioadmin)

export MINIO_ACCESS_KEY=admin

# 自定义设置密码(默认minioadmin)
 

export MINIO_SECRET_KEY=123456

3.设置后台服务启动(9005是后台登录页面，9006是webapi接口端口，用于服务调用)

nohup ./minio server  --console-address :9005 --address :9006 /home/minio/data  > /home/minio/data/minio.log 2>&1 &

4. 防火墙开通端口(非必需,nginx跟防火墙端口任意选一个)
firewall-cmd --add-port=9005/tcp --permanent
firewall-cmd --add-port=9006/tcp --permanent
firewall-cmd --reload

或者nginx代理

二、Springboot项目配置

1.yml配置

minio:
  url: http://bd.baidu123.xyz
  accessKey: 1234567890
  secretKey: 1234567890
  bucketName: myjlis

注释:

url:就是api接口url地址的nginx代理地址,你也可以直接填ip+9006

accessKey与secretKey的值取自:后台管理平台(ip+9005后台平台地址)

 bucketName创建的桶名

如果需要通过域名➕桶名➕文件名方式访问需要进行如下设置
