I've just installed MOngoDB via homebrew und want to start it via command line mongod.
When I do that, i'll get this message:

The last line doesn't sound correct. What is the problem?
The first line of logs says
MongoDB starting : pid=52426 port=27017 dbpath=/data/db 64-bit host=Matthias-MBP".
Notice that host name is Matthias-MBP
, so you can add 127.0.0.1 Matthias-MBP
in /etc/hosts
file. After Ctrl-C
and re-run mongod
, the error message will disappear.
$ cd /private/etc
copy the following code:
##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
127.0.0.1 Matthias-MBP
255.255.255.255 broadcasthost
