It provides a HTTP API for KunlunBase users to do cluster management, provisioning and monitor work, so that uses can install a cluster, a kunlun-server node, a storage shard or a kunlun-storage node by calling such APIs. Such capability enables users to integrate KunlunBase management and provisioning as part of their existing application or GUIs. Cluster_mgr also provide other important cluster maintenance background work to make sure the KunlunBase clusters it serves can work efficiently and reliably.

  1. 新增 cluster_mgr 组成员。
  2. 新增的 cluster_mgr raft 组成员的信息可以持久化在老组成员的配置文件中。

新增 extra.cnf 文件，与 cluster_mgr.cnf 相同路径。如果有新的 raft 组成员加入，则老主成员在收到相关消息后，讲新的组成员信息 flush 到 extra.cnf 中。每次进程重启，cluster_mgr 在重新加载配置文件的时候，需要一并加载 extar.cnf 中的信息。
