MinIO服务器搭建步骤
1.搭建服务
- 新建目录
mkdir -p /usr/local/minio/{bin,etc,data}
- 创建minio用户
groupadd -g 2021 minio
useradd -r -u 2021 -g 2021 -c "Minio User" -s /sbin/nologin minio
# 查看用户
id minio
# uid=2021(minio) gid=2021(minio) 组=2021(minio)
- 下载minio二进制包
curl -O https://dl.minio.io/server/minio/release/linux-amd64/minio
- 更改权限,并移动目录
chmod 750 minio
cp minio /usr/local/minio/bin
- 创建MinIO配置文件
cat >/usr/local/minio/etc/minio.conf<<EOF
MINIO_VOLUMES="/usr/local/minio/data"
MINIO_OPTS="-C /usr/local/minio/etc --address :9000"
MINIO_ACCESS_KEY="xujunkai"
MINIO_SECRET_KEY="12345678"
EOF
- 配置自启动文件
vim /etc/systemd/system/minio.service
[Unit]

[Install]
WantedBy=multi-user.target
- 更改属组，属主
chown -R minio:minio /usr/local/minio
- 启动minio,并设置开机自启动
systemctl daemon-reload
systemctl enable minio
systemctl start minio
systemctl status minio
- 防火墙设置开放9000端口
firewall-cmd --zone=public --add-port=9000/tcp --permanent
firewall-cmd --reload
- 进入Minio web管理页面
-
输入帐号密码。帐号为设置的
MINIO_ACCESS_KEY，密码为设置的MINIO_SECRET_KEY -
创建一个
桶来保存文件
- 上传文件
2.shell命令操作
- 下载客户端
wget https://dl.minio.io/client/mc/release/linux-amd64/mc
- 设置指令的别名：
./mc别名或添加环境变量
alias mc="~/mc"
# 删除alias
unalias mc
# 配置mc环境变量
mv mc /usr/local/minio/
vi /etc/profile
export PATH=$PATH:/usr/local/minio/
source /etc/profile
- 将MinIO Server添加到客户端
mc config host add minio http://172.16.215.141:9000 xujunkai 12345678 --api S3v4
- 桶的基本命令
# 创建 buk2 的桶
mc mb minio/buk2
# 上传当前目录所有文件到buk2桶上
mc cp -r * minio/buk2
# 查找buk2存储桶中html结尾文件
mc find minio/buk2 --name "*.html"
# 设置buk2只读权限 download
# 共可以设置四种权限：none, download只读, upload只写, public
mc policy set download minio/buk2
# 查看buk2存储桶权限
mc policy list minio/buk2
# 共享buk2下baidu.html文件下载路径
mc share download minio/buk2/baidu.html
# 查看存储桶
mc ls minio
# 查看buk2存储桶文件
mc ls minio/buk2
# 设置桶策略为public模式，这样MinIO可以提供永久文件服务
mc policy set public minio/buk2
3.python 操作MinIO
- 版本要求
python 3.6+
- 下载
pip install minio
- 连接
from minio import Minio
client = Minio('0.0.0.0:9000',access_key='xujunkai',secret_key='12345678',secure=False)
- 查询桶是否存在
from minio import Minio
from minio.error import S3Error
try:
client = Minio('0.0.0.0:9000',access_key='xujunkai',secret_key='12345678',secure=False)
found = client.bucket_exists("buk2")
except S3Error as e:
print("error:", e)
print(found)# 返回布尔值 True or False
- 上传文件,若文件已存在，会直接覆盖
client.fput_object("buk2", "1.jpg", "/opt/img/1.jpg")
# 文件不存在会报错FileNotFoundError
- 获取文件数据写入指定文件
data = client.get_object("buk2", "1.jpg")
with open("/opt/1demo.jpg","wb") as fp:
for d in data.stream(1024):
fp.write(d)
- 直接将文件下载到本地
client.fget_object("buk2", "1.jpg", "/opt/static/new.jpg")
- 删除文件
client.remove_object("buk2", file_name)
- 删除多个文件
client.remove_objects("buk2", ["baidu.html", "taobao.html"])
a.获取文件url最长时间期限只能设置为7天？
a.通过桶权限设置方法，修改时间期限限制。
set_bucket_policy(policy)
示例：更改桶权限 设置公共可下载
policy = '{"Version":"2012-10-17","Statement":[{"Effect":"Allow","Principal":{"AWS":["*"]},"Action":["s3:GetBucketLocation","s3:ListBucket"],"Resource":["arn:aws:s3:::%s"]},{"Effect":"Allow","Principal":{"AWS":["*"]},"Action":["s3:GetObject"],"Resource":["arn:aws:s3:::%s/*"]}]}' % (bucket_name, bucket_name)
minioClient.set_bucket_policy(bucket_name=bucket_name, policy=policy)
4.封装python API

client = None
policy = '{"Version":"2012-10-17","Statement":[{"Effect":"Allow","Principal":{"AWS":["*"]},"Action":["s3:GetBucketLocation","s3:ListBucket"],"Resource":["arn:aws:s3:::%s"]},{"Effect":"Allow","Principal":{"AWS":["*"]},"Action":["s3:GetObject"],"Resource":["arn:aws:s3:::%s/*"]}]}'
