安装RapidFS缓存控制器组件

\n

在创建Kubernetes集群类型Cache节点的RapidFS缓存实例前，需准备好可用的Kubernetes集群，并根据集群类型在集群上完成RapidFS缓存控制器（RapidFS Cache Service）组件安装。

\n

容器引擎CCE

\n
    \n
  1. 登录百度智能云容器引擎CCE控制台。
    2. \n
  2. 进入「Helm → Helm 模版 → 百度智能云模版」，搜索 cce-rapidfs-cache-service 并点击安装。
    3. \n

安装前请确认参数中的region与实际地域一致

\n
\n
    \n
  1. 安装完成后，获取RapidFS缓存控制器Token。在kube-system命名空间下查看ConfigMap rapidfs-cache-service-config，其中data.rapidfsCacheControllerToken即为所需的RapidFS缓存控制器Token。

    \n
  1. 进入数据湖存储加速⼯具RapidFS控制台。
    2. \n
  2. 在实例列表页面，点击左上角“创建实例”，在弹窗中进行新建RapidFS的各项参数配置。具体参数说明如下：

参数配置说明
基本信息付费模式按量付费
地域即该RapidFS缓存实例所在的地域，需与数据源所在的对象存储BOS以及后续挂载的客户端云服务器保持一致。
可用区百度智能云根据当前资源情况默认分配一个可用区，用户可根据需求选择RapidFS缓存实例所在可用区。每一个地域中都包含若干可用区，这里将显示区域内所有可部署RapidFS服务的可用区。建议将RapidFS缓存实例和计算资源（如BCC等）部署在相同可用区，以达到最优性能体验 。目前1个 RapidFS缓存实例仅支持选择1个可用区。
网络选择（VPC）用户根据需求选择要与RapidFS缓存实例关联的VPC网络，所选VPC需与客户端云服务器所在VPC相同，或已实现网络互通，否则客户端将无法访问RapidFS实例。每个地域提供一个默认VPC，用户可按需创建新的VPC。
网络选择（子网）用户根据需求选择要与 RapidFS 缓存实例关联的VPC下的子网。
实例名称支持大小写字母、数字、中文以及-_ /.特殊字符，必须以中文或字母开头，长度1-65。
配置信息说明
部署模式选择Master托管时，需要设置Master规格和Cache接入类型。
适用场景：在VPC内复用客户已购买计算节点（如BCC、CCE、百舸全托管资源池等）中的闲置本地磁盘构建缓存集群，按实际纳管的存储容量计费，具备更高性价比，适用于希望降低成本、对BOS数据进行缓存加速且具备一定资源管理能力的场景。
说明：
1. 目前白名单开发，如需使用，请提交工单申请。
2. Master托管模式下，除Master服务配置费用外，RapidFS还会根据实际管理的总容量收取管理容量费用，详情请参见RapidFS 计费和价格。
Master规格您可以选择M1型和M2型。
  • M1 型适用于文件数在10亿，Worker节点上限 50 个，单个Worker节点可挂载数据盘上限4个的场景
  • M2 型适用于文件数在50亿，Worker节点上限400个，单个Worker节点可挂载数据盘上限8个的场景。
    • Cache接入类型您可根据后续接入的Cache节点类型选择容器引擎CCE、自有Kubernetes集群。选择后，后续仅支持添加同类型节点。
    根据所选Cache接入类型，填写在前一步安装RapidFS缓存控制器组件时获取的对应ID和Token信息：CCE集群ID（或RapidFS缓存控制器ID与Token），完成关联配置。
    其他设置标签支持按各种标准（如用途、所有者或项目）对资源进行分类；每个标签包含键和值两部分。
    \n
      \n
    1. 请详细检查您的缓存实例配置，确认无误后提交订单，缓存实例将在 3-5 分钟内创建完成。
