Is the webinterface also using authentication for mongodb? Could you post your graylog2.conf and mongodb.yml?

from graylog2-server.

Contents of /etc/graylog2.conf

# On which port (UDP) should we listen for Syslog messages? (Standard: 514)  
syslog_listen_port = 514
syslog_protocol = udp

# MongoDB Configuration
mongodb_useauth = true
mongodb_user = grayloguser
mongodb_password = 123
mongodb_host = localhost
#mongodb_replica_set = localhost:27017,localhost:27018,localhost:27019
mongodb_database = graylog2
mongodb_port = 27017
mongodb_max_connections = 500

# The (pre-allocated) size of the messages collection in bytes.. (All your syslog and GELF messages are stored here. Standard: 50000000 [~50MB])
messages_collection_size = 50000000 

# Graylog Extended Log Format (GELF)
use_gelf = true
gelf_listen_port = 12201

Contents of mongodb.yml
production:
hostname: localhost
database: graylog2

"graylog2-web-interface" works means: no exceptions is generated while browsing it. Unfortunately my mongodb is empty so there's nothing to show.

from graylog2-server.

Try to set mongodb_useauth to false. Also: Is the web interface running on the same host as the server?

from graylog2-server.

To use authentication you have to do:

• start mongod with "--auth"
• connect to monodb

  ./mongo
  MongoDB shell version: 1.6.5
  connecting to: test
  
  

set admin user (after this you always have to authenticate)

use admin
db.addUser("myadminuser","password")

authenticate

db.auth("myadminuser","password")

add user for the graylog2 db

use graylog2
db.addUser("grayloguser","123");

PS: to use the password "123" in mongodb.yml be sure to use quotation marks, otherwise you'll get an exception.

Thanks. Did this fix your problem?

Try to set mongodb_useauth to false.

This solved the issue.

Also: Is the web interface running on the same host as the server?

Yes, everything is running on the same server.

I tried also the solution proposed by philgh but it didn't work.

from graylog2-server.

Great. Thank you both!
