#这两个配置是一定要的，不然插入数据时，数据只会到shard1，这些业务逻辑操作，可以写另外一个shell文件导入。
#最后要分片的数据库一定要执行
db.runCommand( { enablesharding :"testdb"});

#指定数据库里需要分片的集合和片键
#db.runCommand( { shardcollection : "testdb.table1",key : {id: 1} } )
#hashed：均匀分布数据
db.runCommand( { shardcollection : "testdb.table1",key : {id:'hashed' } } )

#再介绍工作时使用的mongodb可视化工具：MongoVUE，可以分别连进去20000，22001，22002，22003查看配置，插入切片数据的分布。
