2.2. 设置 Kerberos 身份

在 Data Grid Server 配置中的安全域中添加 Kerberos 身份，以使用包含服务主体名称和加密密钥（派生自 Kerberos 密码）的 keytab 文件。

先决条件

具有 Kerberos 服务帐户主体。

注意

keytab 文件可以包含用户和服务帐户主体。但是，Data Grid 服务器只使用服务帐户主体，这意味着它可以向客户端提供身份并允许客户端与 Kerberos 服务器进行身份验证。

在大多数情况下，您可以为 Hot Rod 和 REST 端点创建唯一的主体。例如，如果您在 "INFINISPAN.ORG" 域中有"datagrid"服务器，则应创建以下服务主体：

HotRod/datagrid@INFINISPAN.ORG 标识 Hot Rod 服务。
HTTP/datagrid@INFINISPAN.ORG 标识 REST 服务。

流程

为 Hot Rod 和 REST 服务创建 keytab 文件。

Linux

ktutil
ktutil:  addent -password -p datagrid@INFINISPAN.ORG -k 1 -e aes256-cts
Password for datagrid@INFINISPAN.ORG: [enter your password]
ktutil:  wkt http.keytab
ktutil:  quit

ktutil
ktutil:  addent -password -p datagrid@INFINISPAN.ORG -k 1 -e aes256-cts
Password for datagrid@INFINISPAN.ORG: [enter your password]
ktutil:  wkt http.keytab
ktutil:  quit

将 keytab 文件复制到 Data Grid Server 安装的 server/conf 目录中。
打开 Data Grid Server 配置进行编辑。
在 Data Grid 服务器 安全域中添加服务器事件定义。
指定向 Hot Rod 和 REST 连接器提供服务主体的 keytab 文件的位置。
将 Kerberos 服务主体命名为 Kerberos。
保存对您的配置的更改。
