1.安装minio

这里采用docker进行安装。

搜索该镜像：docker search minio

找到了镜像：minio/minio

拉取镜像：docker pull minio/minio

启动镜像：

docker run --name minio -p 9090:9000 -p 9999:9999 -d \
--restart=always -e \
"MINIO_ROOT_USER=minioadmin" \
-e "MINIO_ROOT_PASSWORD=minioadmin123?" \
-v /home/minio/data:/data \
-v /home/minio/config:/root/.minio minio/minio server /data --console-address '0.0.0.0:9999'

浏览器访问minio的控制台：

http://ip:port

访问到网页如下：

2.配置minio

1.创建一个放图片的目录

登录网页进去：

点击左侧Buckets页面，然后点击右边的 Create Bucket 去创建一个目录，这个目录，如下，我创建了一个imgs，这个目录用来放上传的图片，需要记住这个目录，代码里面需要用

2.创建上传文件需要的key

需要把这两个key复制出来，代码里面需要用，就相当于账户密码之类的

3.springboot整合minio

1. 导入maven

        <!--minio--><dependency><groupId>io.minio</groupId><artifactId>minio</artifactId><version>8.2.1</version></dependency>

2.配置yml文件

# minio文件系统配置
minio:# minio配置的地址，端口9090url: http://xxx.xx.xx.xx:9090# 账号accessKey: RKGZKAUGHKDY0XVN# 密码secretKey: HmTlAJoll7V0OjfBoyKmsIGF# MinIO桶名字bucketName: imgs
