大多数基于 AWS S3 开发的工具都有其自定义访问地址的方法,下面以一些常用工具为例,说明如何对接 QingStor 对象存储。

AWS SDK for Python

  1. 安装 Boto 类库:

    > pip install boto
  2. 编写程序:

    > cat boto-to-qingstor.py
    import boto
    conn = boto.connect_s3(
        aws_access_key_id='PLLZOBTTZXGBNOWUFHZZ',
        aws_secret_access_key='MnIjI58zC8AX07xotHXcm6grwFgOXhaJQHkTCX2X',
        host='s3.pek3a.qingstor.com'
    )
    bucket = conn.get_bucket('mybucket')
    key = bucket.get_key("mykey")

AWS CLI

  1. 安装 AWS CLI 工具:

    > pip install awscli
  2. 编辑配置文件:

    > cat ~/.aws/config
    [profile qingstor]
    region = pek3a
    output = json
    s3 =
        signature_version = s3v4
  3. 设置访问密钥:

    >  cat ~/.aws/credentials
    [qingstor]
    aws_access_key_id = PLLZOBTTZXGBNOWUFHZZ
    aws_secret_access_key = MnIjI58zC8AX07xotHXcm6grwFgOXhaJQHkTCX2X
  4. 命令行执行:

    > aws s3api put-object --bucket mybucket --key puppy.jpg --body ~/Pictures/puppy.jpg --endpoint-url 'https://s3.pek3a.qingstor.com' --profile qingstor
    {
        "ETag": "\"c3872b49cb244269aad8cd4275a41c4a\""
    }

s3fs

  1. 按照文档的步骤编译并安装 s3fs:

    https://github.com/s3fs-fuse/s3fs-fuse/blob/master/README.md
  2. 设置访问密钥:

    > cat  /root/.s3fs/credentials
    PLLZOBTTZXGBNOWUFHZZ:MnIjI58zC8AX07xotHXcm6grwFgOXhaJQHkTCX2X
    EOF
    > chmod 600 /root/.s3fs/credentials

    填写说明:

    • 密钥文件填写格式为:ACCESS_KEY_ID:ACCESS_KEY_SECRET

    • 假设 ACCESS_KEY_ID 的值为 PLLZOBTTZXGBNOWUFHZZ;ACCESS_KEY_SECRET 的值为 MnIjI58zC8AX07xotHXcm6grwFgOXhaJQHkTCX2X。则填写内容为:

      PLLZOBTTZXGBNOWUFHZZ:MnIjI58zC8AX07xotHXcm6grwFgOXhaJQHkTCX2X

    • 密钥文件的权限需设置为 600。

  3. 挂载 Bucket 至本地目录:

    > mkdir -p /mnt/mybucket
    > s3fs mybucket /mnt/mybucket -o passwd_file=/root/.s3fs/credentials -o url=http://s3.pek3a.qingstor.com
    > df -T | grep s3fs
    s3fs           fuse.s3fs 274877906944        0 274877906944   0% /mnt/mybucket
  4. 测试文件系统操作:

    > echo 'hello world' > /tmp/hello.txt
    > cp -v /tmp/hello.txt /mnt/mybucket/
    ‘/tmp/hello.txt’ -> ‘/mnt/mybucket/hello.txt’
    > ls -l /mnt/mybucket/hello.txt
    ---------- 1 root root 4635 Aug 11 23:26 /mnt/mybucket/hello.txt
    > cat /mnt/mybucket/hello.txt
    hello world
  5. 配置开机自动挂载 s3fs :

    1. 创建 /etc/passwd-s3fs 文件,可参考前文设置访问密钥*相关内容:

      > cat /etc/passwd-s3fs
      PLLZOBTTZXGBNOWUFHZZ:MnIjI58zC8AX07xotHXcm6grwFgOXhaJQHkTCX2X
      EOF
      > chmod 600 /etc/passwd-s3fs
    2. 修改 /etc/fstab 文件,在该文件末尾添加如下内容,其中 your_bucket_nameyour_mount_pointyour_url 需根据实际情况进行填写:

      s3fs#your_bucket_name your_mount_point fuse _netdev,url=your_url,allow_other 0 0

      示例:

      s3fs#mybucket /mnt/mybucket fuse _netdev,url=http://s3.pek3a.qingstor.com,allow_other 0 0
    3. 执行如下命令行挂载,若无报错信息,则说明设置正常。

      > mount -a
    4. 若客户端操作系统为 Centos 6.5,还需执行如下命令:

      > chkconfig netfs on
    5. 至此您的系统已经成功的配置了开机自动挂载 s3fs。

s3cmd

  1. 安装 s3cmd 工具:

    > pip install s3cmd
  2. 根据实际情况,编辑如下配置文件的相关字段:

    > cat ~/.s3cfg
    [default]
    access_key = PLLZOBTTZXGBNOWUFHZZ
    secret_key = MnIjI58zC8AX07xotHXcm6grwFgOXhaJQHkTCX2X
    bucket_location = pek3a
    host_base = s3.pek3a.qingstor.com
    host_bucket = %(bucket)s.s3.pek3a.qingstor.com
  3. 执行如下命令行,上传文件至 QingStor 对象存储:

    > s3cmd put /tmp/hello.txt s3://mybucket/
    upload: '/tmp/hello.txt' -> 's3://mybucket/hello.txt'  [1 of 1]
    4635 of 4635   100% in    0s   523.36 B/s  done
