服務器重裝，環境配置正常，domain沒有變動，啟動AdminServer失敗。

==============================================
經過查閱資料了解到，原來當機器存在多個網卡時，服務器可能會無法確認選擇正確的適配器，而我的機器由於有虛擬機和無線網卡，確實存在多個適配器，這個解決辦法是修改/etc/hosts文件
127.0.0.1 localhost.localdomain localhost
【機器名】【IP】【域名】
添加后發現問題依舊，后經測試發現，由於重裝后未給用戶 /etc/hosts的讀權限，導致無法識別DNS。
增加權限后，問題解決~！
