• 开源支持 S3 协议的对象存储
  • 支持多个客户端访问,支持分布式集群部署,容器化部署
  • 考虑集成在项目中,作为后端存储进行测试

Introduction

Features

  • Open source Object Storage: MINIO
  • Amazon S3, Apache License v2.0
  • Client/Server Mode
  • Support Erasure Code
  • Website: https://min.io/
  • Github Repo:https://github.com/minio/minio

Details

  • MinIO 是一个基于Apache License v2.0开源协议的对象存储服务。它兼容亚马逊S3云存储服务接口,非常适合于存储大容量非结构化的数据,例如图片、视频、日志文件、备份数据和容器/虚拟机镜像等,而一个对象文件可以是任意大小,从几kb到最大5T不等。
  • MinIO是一个非常轻量的服务,可以很简单的和其他应用的结合,类似 NodeJS, Redis 或者 MySQL。
  • [Java Client API]
  • [Java Client API -zh]
  • 官方测试地址:https://play.minio.io:9000

Start

Docker

  • Pull Image
docker pull minio/minio
  • Run image (without access_key & secret_key)
# -it 运行参数
# -p 指定端口
# -d 后台运行
docker run -it -p 9000:9000 -d minio/minio server /data
  • Run image
docker run -p 9000:9000 --name minio \
-d --restart=always \
-e "MINIO_ACCESS_KEY=admin" \
-e "MINIO_SECRET_KEY=admin123456" \
-v /home/data:/data \
-v /home/config:/root/.minio \
minio/minio server /data

AWS S3 SDK for C++

Prerequisite

make -j `nproc` -C aws-cpp-sdk-core
make -j `nproc` -C aws-cpp-sdk-s3
  • 安装头文件和库到一个目录
make install DESTDIR=/c++/C-Example/linux/install -C ../build/aws-cpp-sdk-s3
make install DESTDIR=/c++/C-Example/linux/install -C ../build/aws-cpp-sdk-core

Sample Code: List Buckets

  • Test Code: 使用 Minio 示例测试。
#include <iostream>
#include <aws/s3/S3Client.h>
#include <aws/core/Aws.h>
#include <aws/core/auth/AWSCredentialsProvider.h>

using namespace Aws::S3;
using namespace Aws::S3::Model;
using namespace std;

int main(int argc, char* argv[]) {
    Aws::SDKOptions options;
    options.loggingOptions.logLevel = Aws::Utils::Logging::LogLevel::Trace;
    Aws::InitAPI(options);

    Aws::Client::ClientConfiguration cfg;
    cfg.endpointOverride = "https://play.minio.io:9000";  // S3服务器地址和端口
    cfg.scheme = Aws::Http::Scheme::HTTP;
    cfg.verifySSL = false;

    Aws::Auth::AWSCredentials cred("Q3AM3UQ867SPQQA43P2F", "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG");  // 认证的Key
    S3Client client(cred, cfg, Aws::Client::AWSAuthV4Signer::PayloadSigningPolicy::Never, false);

    auto response = client.ListBuckets();
    if (response.IsSuccess()) {
        auto buckets = response.GetResult().GetBuckets();
        for (auto iter = buckets.begin(); iter != buckets.end(); ++iter) {
            cout << iter->GetName() << "\t" << iter->GetCreationDate().ToLocalTimeString(Aws::Utils::DateFormat::ISO_8601) << endl;
        }
    } else {
        cout << "Error while ListBuckets " << response.GetError().GetExceptionName()
            << " " << response.GetError().GetMessage() << endl;
    }

    Aws::ShutdownAPI(options);
    return 0;
}

IDE Configuration (VS Code Remote)

  • VS Code Remote 开发时可能缺少对 gcc 的相关配置,示例如下:
{
    "configurations": [
        {
            "name": "Linux",
            "includePath": [
                "${workspaceFolder}/install/**"
            ],
            "defines": [],
            "compilerPath": "/usr/bin/gcc",
            "cStandard": "c11",
            "cppStandard": "c++14",
            "intelliSenseMode": "clang-x64"
        },
        {
            "name": "huawei-cloud",
            "includePath": [
                "${workspaceFolder}/install/**"
            ],
            "defines": [],
            "compilerPath": "/usr/bin/gcc",
            "cStandard": "c11",
            "cppStandard": "c++14",
            "intelliSenseMode": "gcc-x64"
        }
    ],
    "version": 4
}

CMake Env Configuration

  • 编写 CMakeList.txt
cmake_minimum_required (VERSION 2.8)
# 项目信息
project (Demo)

add_compile_options( -std=c++11 )
include_directories(/c++/C-Example/linux/install/usr/local/include)
link_directories(/c++/C-Example/linux/install/usr/local/lib64)

# 指定生成目标
add_executable(Demo object_storage.cpp)
target_link_libraries(Demo -laws-cpp-sdk-core -laws-cpp-sdk-s3)

Build And Run

  • 运行 CMake 编译成可执行文件
cmake .
make
  • make 时可能报错,缺少依赖,如 aws-c-common, aws-checksums and aws-c-event-stream. 在安装 AWS SDK 时会默认将这些依赖包放在 .deps/install/lib,如果没有安装,自行 make,make 完成之后导出
export LD_LIBRARY_PATH=/c++/C-Example/linux/.deps/install/lib64
  • 重新编译我们的 demo
cmake .
make
  • 编译成功,运行可执行文件
./Demo

main.c
#include "S3TestWrapper.h"
#include<stdio.h>

int main(int argc, char* argv[]) {
    printf("start!\n");
    char *BucketName = "test";
