如何在Java中远程连接MongoDB？

Question

I am trying to connect MongoDB at Remote server connected in LAN. I tried to connect using MongoClient() method by using IP of remote machine:

Mongo m=new MongoClient("192.168.1.38",27017);

However, it gives the exception:

java.net.NoRouteToHostException: No route to host.

Answer 1

You are probably connecting fine but don't have sufficient privileges to run show dbs.

You don't need to run the db.auth if you pass the auth in the command line:

mongo somewhere.mongolayer.com:10011/my_database -u username -p password

Once you connect are you able to see collections?

show collections

If so all is well and you just don't have admin privileges to the database and can't run the show dbs

Answer 2

You can use MongoClientUri to connect remotely in JAVA

For eg MongoClientUri client=new MongoClientUri(machine addres);
