列出分片
mongos> db.runCommand( { listshards : 1 } )
{
"shards" : [
{
"_id" : "shard2",
"host" : "sh2/10.0.0.152:28024,10.0.0.152:28025"

mongos> sh.status();
至此MongoDB的分片集群就搭建完成。
数据库分片配置
激活数据库分片功能
语法：( { enablesharding : "数据库名称" } )
mongos> db.runCommand( { enablesharding : "test" } )
指定分片建对集合分片，范围片键--创建索引
mongos> use test
mongos> db.vast.ensureIndex( { id: 1 } )
mongos> use admin
mongos> db.runCommand( { shardcollection : "test.vast",key : {id: 1} } )
集合分片验证
mongos> use test
mongos> for(i=0;i<20000;i++){ db.vast1.insert({"id":i,"name":"clsn","age":70,"date":new Date()}); }
mongos> db.vast.stats()
