mongo表分片

1、激活数据库分片功能

mongos> db.runCommand( { enablesharding : "test" } )  

2、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} } )

3、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()
