+# 关联/解绑集群流程设计
+
+## 1.关联集群
+
+dsms-ui端登录后，先发送POST /api/cluster/about请求到dsms-engine端，dsms-engine端查询数据库cluster表中数据，然后像dsms-ui端返回是否已绑定集群；若已绑定集群，则dsms-ui端跳转概览信息页面，若尚未绑定集群，则跳转到提示关联集群页面。  
+
+添加集群绑定检查后的登录功能流程如下图所示：

+
+dsms-ui端登录跳转到关联集群页面时，在关联集群页面输入一些集群的名称和VIP地址等信息，然后发送POST /api/cluster/bind请求到dsms-engine端，dsms-engine端经过一系列校验后返回关联集群功能操作的结果。
