# create a super administrator
use admin
db.createUser({user: 'root', pwd: 'root', roles: ['clusterAdmin', 'dbAdminAnyDatabase', 'userAdminAnyDatabase', 'readWriteAnyDatabase']})
db.auth('root', 'root')

use leanote
db.createUser({user: 'leanote', pwd: 'leanotepwd', roles: ['readWrite']})
db.auth('leanote', 'leanotepwd')
# stop mongodb service and quit
use admin
db.shutdownServer()

    # you website public ip or url
    site.url=http://www.example.com:9000
    # mongodb
    db.username=leanote
    db.password=leanotepwd
    # You Must Change It !!!
    app.secret=[you can modify it at will]
# start mongodb service
mongod --auth --config /usr/local/apps/mongodb/conf/mongodb.conf
# start leanote
nohup revel run src/github.com/leanote/leanote >leanote.log 2>&1 &

Now, you can try to open www.example.com:9000 !
The default account is admin and password is abc123.
