# 安装
curl https://dl.minio.org.cn/client/mc/release/linux-amd64/mc -O /usr/local/bin/mc
chmod +x /usr/local/bin/mc

# 首先需要使用 mc alias 命令将 S3 服务添加到 mc 别名配置 中
mc alias set myminio http://12.34.56.78:9000 ACCESS_KEY SECRET_KEY

mc alias ls myminio                                 # 查看别名的配置
mc alias rm myminio                                 # 删除别名配置
mc ls myminio                                       # 列出存储桶
mc mb myminio/bucket-by-mc                          # 创建存储桶
mc rb myminio/bucket-by-mc                          # 删除存储桶
mc rm myminio/bucket-by-mc/file_name                # 删除存储桶中的文件
mc cp file_name myminio/bucket-by-mc                # 上传文件到存储桶
mc get myminio/bucket-by-mc/file_name ./file_name   # 下载存储桶中的文件
