基于MinIO的对象存储增删改查
MinIO是一个高性能的分布式对象存储服务。Python的minio库可操作MinIO，包括创建/列出存储桶、上传/下载/删除文件及列出文件。

minio.exe --help
minio.exe server --help
ME:
minio.exe server - start object storage server
AGE:
minio.exe server [FLAGS] DIR1 [DIR2..]
minio.exe server [FLAGS] DIR{1...64}
minio.exe server [FLAGS] DIR{1...64} DIR{65...128}
R:
DIR points to a directory on a filesystem. When you want to combine
multiple drives into a single large system, pass one directory per
filesystem separated by space. You may also use a '...' convention
to abbreviate the directory arguments. Remote directories in a
distributed setup are encoded as HTTP(s) URIs.
AGS:
--config value specify server configuration via YAML configuration [%MINIO_CONFIG%]
--address value bind to a specific ADDRESS:PORT, ADDRESS can be an IP or hostname (default: ":9000") [%MINIO_ADDRESS%]
--console-address value bind to a specific ADDRESS:PORT for embedded Console UI, ADDRESS can be an IP or hostname [%MINIO_CONSOLE_ADDRESS%]
--ftp value enable and configure an FTP(Secure) server
--sftp value enable and configure an SFTP server
--certs-dir value, -S value path to certs directory (default: "C:\\Users\\lilon\\.minio\\certs")
--quiet disable startup and info messages
--anonymous hide sensitive information from logging
--json output logs in JSON format
--help, -h show help
AMPLES:
1. Start MinIO server on "/home/shared" directory.
C:\> minio.exe server /home/shared
2. Start single node server with 64 local drives "/mnt/data1" to "/mnt/data64".
C:\> minio.exe server /mnt/data{1...64}
3. 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"
启动服务
$ minio.exe server --address :9001 minio_data\

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 Minio
client = 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)
