> db.runCommand({"replSetInitiate" : { "_id" : "hnrconfig" ,"members" : [ { "_id" : 1, "host" : "192.168.115.11:10000"},{ "_id" : 2, "host" : "192.168.115.12:10000"},{"_id" : 3, "host" : "192.168.115.11:10001"}]}})
8.启动mongos服务，此时没有任何数据
9.导入备份的config数据
/usr/local/mongodb/bin/mongorestore -h 192.168.115.11:10000 -d config configdata/config/
在mongos查询，但是查询数据会出现超时，数据无法查询
10.在mongos执行如下命令
mongos> sh.enableSharding("shardtest")
{ "ok" : 0, "errmsg" : "Operation timed out", "code" : 50 }
mongos日志
