linux - couldn't connect to server 127.0.0.1 shell/mongo.js
when i setup mongodb in my ubuntu , i try : ./mongo it show this error :


Manually remove the lockfile: sudo rm /var/lib/mongodb/mongod.lock
Run the repair script: sudo -u mongodb mongod -f /etc/mongodb.conf    --repair

Please note the following:

You must run this command as the mongodb user. If you run it as root,
then root will own files in /var/lib/mongodb/ that are necessary to
run the mongodb daemon and therefore when the daemon trys to run
later as the mongodb user, it won't have permissions to start. In
that case you'll get this error: Unable to create / open lock file
for lockfilepath: /var/lib/mongodb/mongod.lock errno:13 Permission
denied, terminating.
On Ubuntu, you must specify the configuration file /etc/mongodb.conf
using the -f flag. Otherwise it will look for the data files in the
wrong place and you will see the following error: dbpath (/data/db/)
does not exist, terminating.
