Minio 搭建图片服务器
环境准备
- linux operating system
- docker
docker 安装 Minio 及配置
docker run -p 9000:9000 -p 9001:9001 --name minio -v /data/minio/data:/data -e MINIO_ROOT_USER=admin -e MINIO_ROOT_PASSWORD=you_password -d minio/minio server /data --console-address ":9001"
安装好之后浏览器输入 http://IP:9001 进入控制页面，输入上面定义的 MINIO_ROOT_USER 和 MINIO_ROOT_PASSWORD登录即可进入到控制页面
然后创建一个 bucket
bucket创建好之后创建一个User(这里的公钥和私钥可以随便填写) 注意要赋予读写权限
进入到刚刚创建的user 下创建一个 service account
如下图所示 将生成下来的密钥保存好
编写代码

通过下面的html就能够对文件上传进行测试了，其他的直接通过浏览器测试就好了
- upload.html
```html
<form action="http://IP:PROT/files/upload" method="post" enctype="multipart/form-data">
<p><input type="file" name="file"></p>
<p><input type="submit" value="submit"></p>
</form>
