Just make sure the ownership of the directory is the same as the user ubuntu tries to start mongodb with (it’s not root, even if you’re doing sudo service mongodb start, it’s “mongodb”)<\/p>\n
Extra points for whoever tells me how the hell to change the default user to something else.
\nUbuntu\/Mongo’s documentation says that for upstart based systems you can do this at \/etc\/init.d\/mongodb.conf, but such file doesn’t exist for Ubuntu 12.04.<\/p>\n
hope this helps<\/p>\n","protected":false},"excerpt":{"rendered":"
