It is the first time that the database is used，I create the database path /opt/ros/mongodb_store,then run the instruction rosrun mongodb_store mongodb_server.py

It's the error returned: [INFO] [WallTime: 1446001409.463378] Mongo server address: bob:62345 [INFO] [WallTime: 1446001409.483994] Found MongoDB version 2.4.9 [INFO] [WallTime: 1446001409.520237] Wed Oct 28 11:03:29.519 [initandlisten] MongoDB starting : pid=7336 port=62345 dbpath=/opt/ros/mongodb_store 64-bit host=jenniful-Lenovo [INFO] [WallTime: 1446001409.520702] Wed Oct 28 11:03:29.519 [initandlisten] db version v2.4.9 [INFO] [WallTime: 1446001409.520944] Wed Oct 28 11:03:29.519 [initandlisten] git version: nogitversion [INFO] [WallTime: 1446001409.521211] Wed Oct 28 11:03:29.519 [initandlisten] build info: Linux orlo 3.2.0-58-generic #88-Ubuntu SMP Tue Dec 3 17:37:58 UTC 2013 x86_64 BOOST_LIB_VERSION=1_54 [ERROR] [WallTime: 1446001409.521437] MongoDB process stopped!

Watch out as the DB might need recovery time at next run.

The reason is I don't have the permissions to write to /opt/ros/mongodb_store,run chmod 777 /opt/ros/mongodb_store to solve the problem

marc-hanheide commented 8 years ago

you easily run this as rosrun mongodb_store mongodb_server.py _database_path:=<your path> with your own path.

I will be appriciate if you can help me to solve another problem. After rosrun mongodb_store mongodb_server.py,I execute rosrun mongodb_store message_store_node.py. I get:

Traceback (most recent call last): File "/home/jenniful/catkin_ws/src/mongodb_store/mongodb_store/scripts/message_store_node.py", line 240, in store = MessageStore() File "/home/jenniful/catkin_ws/src/mongodb_store/mongodb_store/scripts/message_store_node.py", line 41, in init self._mongo_client=MongoClient(db_host, db_port) File "/home/jenniful/catkin_ws/src/mongodb_store/mongodb_store/src/mongodb_store/util.py", line 82, in mongo_client_wrapper return pymongo.MongoClient(_args, *_kwargs) File "/usr/lib/python2.7/dist-packages/pymongo/mongo_client.py", line 352, in init raise ConnectionFailure(str(e)) pymongo.errors.ConnectionFailure: could not connect to bob:62345: [Errno -2] Name or service not known

I am sure the mongodb_port is 62345 and mongodb_host is bob.

Thanks.

To me that seems to be a problem in your network setup. Is there even a machine called "bob" in your setup? And can that name be resolved by the system?

marc-hanheide commented 8 years ago

So, is "bob" in your /etc/hosts?
