对象存储服务minio
1、安装服务器端
网址：https://min.io/download#/linuxwget https://dl.min.io/server/minio/release/linux-amd64/minio
指定账号密码export MINIO_ROOT_USER=admin export MINIO_ROOT_PASSWORD=admin123
启动命令nohup /usr/local/minio/minio server --console-address ＂:9001＂ /usr/local/minio/data > /usr/local/minio/log/minio.log 2>&1 &
或者export MINIO_ACCESS_KEY=username export MINIO_SECRET_KEY=password nohup /usr/local/minio/minio server --address=0.0.0.0:9000 --console-address ＂:9001＂ --config-dir /usr/local/minio/config /usr/local/minio/data > /usr/local/minio/log/minio.log 2>&1 &
登录管理页面IP+9001
设置开机启动1.打开开机自启文件 vim /etc/rc.local 2.添加自启脚本 nohup /usr/local/minio server /home/minio/data > /home/minio/data/minio.log 2>&1 & 3.修改权限 chmod +x /etc/rc.local
2、SpringBoot整合MinIO
2.1、导入 minio jar包 io.minio minio 7.1.0
2.2、配置
application.yml 配置 minio: endpoint: 172.0.0.1 port: 9000 accessKey: minio secretKey: miniopassword secure: false bucketName: ＂my-bucket＂ configDir: ＂/usr/local/minio/data/＂
类配置 /** * minio配置 */ public static class Minio{ /** * minio地址 */ public static String Url=＂http://127.0.0.1:9000＂; /** * AK */ public static String AccessKey=＂minio＂; /** * SK */ public static String SecretKey=＂miniopassword＂; /** * 文件夹 */ public static String BuckeName=＂my-buckeName＂; }
