Start distributed MinIO server on an 32 node setup with 32 drives each, run following command on all the nodes                               C:\> minio.exe server http://node{1...32}.example.com/mnt/export{1...32}                                                                     4. Start distributed MinIO server in an expanded setup, run the following command on all the nodes                                              C:\> minio.exe server http://node{1...16}.example.com/mnt/export{1...32} \                                                                   http://node{17...64}.example.com/mnt/export{1...64}                                                                                   5. Start distributed MinIO server, with FTP and SFTP servers on all interfaces via port 8021, 8022 respectively                                 C:\> minio.exe server http://node{1...4}.example.com/mnt/export{1...4} \                                                                     --ftp="address=:8021" --ftp="passive-port-range=30000-40000" \                                                                         --sftp="address=:8022" --sftp="ssh-private-key=${HOME}/.ssh/id_rsa"

Python实现增删改查

安装依赖

$ pip install minio
Looking in indexes: http://mirrors.aliyun.com/pypi/simple/
Installing collected packages: minio
Successfully installed minio-7.2.15

连接服务

from minio import Minioclient = Minio(endpoint="127.0.0.1:9001",access_key="minioadmin",secret_key="minioadmin",secure=False
)

创建存储桶（Buckets）

def create_bucket():client.make_bucket('bucket1', location="location1")

这里给存储桶命名为bucket1，位置在location1。

列出所有的存储桶

def list_buckets():buckets = client.list_buckets()for bucket in buckets:print(bucket.name, bucket.creation_date)

上传和下载文件

def upload_file():client.fput_object("bucket1", "1.png", "path/to/file/1.png")def download_file():client.fget_object('bucket1', "1.png", 'path/to/file/2.png')

这里的存储桶是bucket1，文件命名为1.png，

移除文件

def remove_file():client.remove_object('bucket1', '1.png')

列出所有的存储对象

def list_objects():objects = client.list_objects('bucket1')for obj in objects:print(obj.object_name)
