Sharding
To connect to a shard cluster, specify the address of one or more
mongos instances in the connection string. Multiple
servers may be delimited by a comma.
<?php// Using one server as the seed list$m = new MongoClient("mongodb://mongos1.example.com:27017");// Using multiple servers as the seed list$m = new MongoClient("mongodb://mongos1.example.com:27017,mongos2.example.com:27017");?>
Regardless of whether each shard is a stand-alone mongod
server or a full replica set, the driver's connection process is the same.
All database communication will be routed through mongos.
For more information on sharding with MongoDB, see the » sharding documentation.
