check with either:
ps -edaf | grep mongo | grep -v grep # "ps" flags may differ on your OS
or
/etc/init.d/mongodb status # for MongoDB version < 2.6
/etc/init.d/mongod status # for MongoDB version >= 2.6
or
service mongodb status # for MongoDB version < 2.6
service mongod status # for MongoDB version >= 2.6
to see if mongod is running (you need to be root to do this, or prefix everything with sudo
). Please note that the ‘grep’ command will always also show up as a separate process.
Check the log file /var/log/mongo/mongo.log
to see if there are any problems reported.
