(Mac) Mac上如何修改本地的hostname

前言

之前運行Spark的時候遇到一個問題. 由於本地hostname不對導致鏈接連不上. 將記錄操作記錄於此.

操作細節

Mac上配置Hostname主要包括2處.

• /etc/hosts

localhost:~ sean$ ls /etc | grep ".*hosts.*"
hosts
hosts.equiv

可以看到就只有2個文件. 無hostname文件.

localhost:~ sean$ cat /etc/hosts
##
# 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
255.255.255.255	broadcasthost
::1             localhost
# Added by Docker Desktop
# To allow the same kube context to work on the host and the container:
127.0.0.1 kubernetes.docker.internal
# End of section

• hostname命令查看

localhost:~ sean$ hostname
localhost

輸入hostname命令即可查看當前電腦的主機. 此處已經進行了修改.

sudo scutil --set HostName yourName

# 操作實例
localhost:~ sean$ sudo scutil --set HostName Yanxm.HelloWorld
Password:
localhost:~ sean$ hostname
Yanxm.HelloWorld
