mongod HostnameCanonicalizationWorker Fehler auf OS X

Question

Ich habe gerade MOngoDB über Homebrew installiert und möchte es über die Befehlszeile mongod starten.

Wenn ich das tue, werde ich diese Meldung:

Die letzte Zeile nicht richtig klingen. Was ist das Problem?

Answer 1

Die erste Zeile von Protokollen sagt

MongoDB starting : pid=52426 port=27017 dbpath=/data/db 64-bit host=Matthias-MBP". 

Beachten Sie, dass Hostname ist Matthias-MBP, so dass Sie 127.0.0.1 Matthias-MBP in /etc/hosts Datei hinzufügen können. Nach Ctrl-C und erneutem Ausführen mongod wird die Fehlermeldung verschwinden.

Answer 2

1. $ cd /private/etc
2. offenen Hosts-Datei in diesem Verzeichnis

3. den folgenden Code kopieren:

   ## 
   # 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 
   ::1    localhost
