解決方法(主要是檢視各個環境變數,使變數報錯最小)
一、
windows登錄檔修改
win+R regedit 確定
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters 下新建
Value Name: DisableDHCPMediaSense
Data Type: DWORD
Value: 1

二、root使用者，
vi /etc/profile
##只保留jdk配置資訊，查詢報錯原因。

source /etc/profile
javac ###檢視是否配置成功。

三、切換到grid使用者
source ~/.bash_profile
