mongod在OS X上的HostnameCanonicalizationWorker错误

mongodb
9

我刚刚通过homebrew安装了MongoDB，并想通过命令行mongod启动它。

当我这样做时，我会收到以下消息：

最后一行听起来不太对。有什么问题吗？

日志的第一行说：

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

请注意主机名为Matthias-MBP，因此您可以在/etc/hosts文件中添加127.0.0.1 Matthias-MBP。 在按下Ctrl-C并重新运行mongod后，错误消息将消失。

  1. $ cd /private/etc
  2. open hosts file in that directory

  3. 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
::1             localhost
