如果您的自建数据库不是部署在阿里云上，它们可能只接受与特定IP地址建立连接。 在这种情况下，您需要将DTS服务器的IP地址段加入到自建数据库对应的安全设置（通常为您自建数据库的防火墙）中，以允许来自DTS服务器的访问。

注意事项

  • 如果源或目标数据库是阿里云数据库实例（例如RDS MySQL、云数据库MongoDB版等），DTS会自动将对应地区DTS服务的IP地址添加到阿里云数据库实例的白名单或ECS的安全规则中，您无需手动添加；如果源或目标数据库是ECS上的自建数据库，DTS会自动将对应地区DTS服务的IP地址添到ECS的安全规则中，您还需确保自建数据库没有限制ECS的访问；如果源或目标数据库是IDC自建数据库或其他云数据库，则需要您手动添加对应地区DTS服务的IP地址，以允许来自DTS服务器的访问。
  • 如果DTS实例的源库或目标库是通过云企业网CEN或专线/VPN网关/智能网关方式接入到阿里云，在初次使用DTS和收到DTS白名单扩容通知时，请将下表中相应地域的本地数据库通过云企业网CEN、专线/VPN网关/智能网关、数据库网关DG接入列的所有IP及IP网段添加到如下的位置中：
  • 如果DTS实例的源库或目标库是通过公网IP方式接入到阿里云，在初次使用DTS和收到DTS白名单扩容通知时，请将下表中对应地域的本地数据库通过公网接入列的所有IP及IP网段添加到实例白名单中。
  • 请确保DTS实例相应地域的网络环境中，已将DTS IP及IP网段全部添加，否则DTS任务容灾后可能会导致新设备无法连接到实例，进而导致任务延迟或中断。
  • DTS自动添加或您手动添加DTS服务的公网IP地址段可能会存在安全风险，一旦使用本产品代表您已理解和确认其中可能存在的安全风险，并且需要您做好基本的安全防护，包括但不限于加强账号密码强度防范、限制各网段开放的端口号、内部各API使用鉴权方式通信、定期检查并限制不需要的网段，或者使用通过内网（专线/VPN网关/智能网关）的方式接入。
  • DTS任务完成或释放后，建议您删除添加的DTS IP地址段。

数据迁移/订阅

  • 数据迁移

    当数据迁移的源或目标数据库为有公网IP的自建数据库、无公网IP:Port的数据库（通过数据库网关DG接入）、通过云企业网CEN接入的自建数据库或通过专线/VPN网关/智能网关接入的自建数据库时，通过下表定位到目标数据库所在区域，获取对应区域DTS服务的IP地址段，并将其加入到源和目标数据库的安全设置中。

    例如：源数据库地区为深圳，目标数据库地区为杭州，您只需要将杭州地区DTS服务的IP地址段加入到源和目标数据库的安全设置中。

  • 数据订阅

    当数据订阅的源数据库为有公网IP的自建数据库、无公网IP:Port的数据库（通过数据库网关DG接入）或通过专线/VPN网关/智能网关接入的自建数据库时，通过下表定位到源数据库所在区域，获取对应的DTS服务的IP地址段并将其加入到源数据库的安全设置中。

说明 如果您的源或目标数据库为有公网IP的自建数据库，且DTS提供的区域未覆盖您自建数据库所在区域，则可以选择填入任意区域DTS服务的IP地址，推荐选择华东1（杭州）DTS服务的IP地址。
表 1. DTS服务的IP地址段信息
说明
  • 区域对应的地域ID，请参见支持的地域列表。
  • 本地数据库通过云企业网CEN、专线/VPN网关/智能网关、数据库网关DG时，所添加的DTS IP地址为阿里云使用地址段（100.64.0.0/10）的子网段。
  • 当DTS添加新服务器时，如果不及时更新自建数据库的白名单设置，可能会导致DTS无法正常连接数据库。为了避免此问题，建议您将100.104.0.0/16添加到可通过内网访问的自建数据库的IP白名单（如CEN的云服务IP或地址段）。

数据同步

当数据同步的源和目标数据库为无公网IP:Port的数据库（通过数据库网关DG接入）、通过云企业网CEN接入的自建数据库或通过专线/VPN网关/智能网关接入的自建数据库时，您需要根据业务情况进行配置：
  • 如果需要放开DTS对源数据库的访问限制，您需要通过下表定位到源和目标数据库所在区域，获取对应区域DTS服务的IP地址段，并将其加入到源数据库的安全设置中。

    例如：源数据库地区为深圳，目标数据库地区为杭州，您需要将深圳和杭州地区DTS服务的IP地址段，都加入到源数据库的安全设置中。

  • 如果需要放开DTS对目标数据库的访问限制，通过下表定位到目标数据库所在区域，获取对应区域DTS服务的IP地址段，并将其加入到目标数据库的安全设置中。

    例如：源数据库地区为深圳，目标数据库地区为杭州，您只需将杭州地区DTS服务的IP地址段，加入到目标数据库的安全设置中。

说明
  • 数据同步暂不支持本地数据库为有公网IP的自建数据库。
  • 本地数据库通过云企业网CEN、专线/VPN网关/智能网关、数据库网关DG时，所添加的DTS IP地址为阿里云使用地址段（100.64.0.0/10）的子网段。
