minio安装及使用

前言

前几天弄一个报告文件生成和下载的功能，由于是镜像部署的程序而且用了k8s的多节点部署，因此需要一个共享文件存储的功能，上网查了一下最后准备用minio

minio安装

下载并赋予读写权限

mkdir minio
wget https://dl.min.io/server/minio/release/linux-amd64/minio
chmod +x minio

执行

./minio

新建文件目录

mkdir data

启动

./minio server --address 0.0.0.0:9006 --console-address 0.0.0.0:9007 data > minio.log 2>&1 &

查看日志

tail -f minio.log

minio使用（java+spring boot使用）

pom

<dependency>
    <groupId>io.minio</groupId>
    <artifactId>minio</artifactId>
    <version>7.1.0</version>
</dependency>

配置文件

minio.access-key=your-access-key
minio.secret-key=your-secret-key
minio.endpoint=http://your-minio-endpoint

config类
