solr集群管理，

在九个节点上设置三个shard三个replica,指定在每个节点上均匀分配的创建collection方式

1. 区分solr实例, core, collection, shard, replica 概念

2. create集合的重要参数, numshard, replicafactor, createnodeset

    addreplica的重要参数 shard(shard1,shard2...), node(search-2.xxxxxxxxxx.com:8993_solr..)
    deletereplica 的重要参数 shard , replica(core_node1,core_node2...)

3. 以上参数对应的value
