Installing and running ArangoDB

database

#1

Hi, I want to use ArangoDB in my workspace. The installation in a cloned workspace goes with no trouble, except for these lines:
/etc/init.d/arangodb3: 37: ulimit: error setting limit (Operation not permitted) /etc/init.d/arangodb3: 38: ulimit: error setting limit (Invalid argument)
that appear when starting arangodb service.
Then, I proceed to change the following line in /etc/arangodb3/arangod.conf:
endpoint = tcp://127.0.0.1:8529
to this one:
endpoint = tcp://[workspace]-[username].c9users.io:8081
in order to change the default running port of ArangoDB to a c9-allowed port. That´s done with arangodb service stopped, so I the start it again, to see these lines printed out:
/etc/init.d/arangodb3: 37: ulimit: error setting limit (Operation not permitted) /etc/init.d/arangodb3: 38: ulimit: error setting limit (Invalid argument) {startup} starting up in daemon mode changed working directory for child process to '/var/tmp'
and then it gets my terminal back (it doesn´t keep like an ongoing process) so I type:
sudo service arangodb status
which gives:
* arangod is not running
How can I get this to work? Thank you!
