對完全限定功能變數名稱 (FQDN) customer.com.mx 的 ping 測試收到來自本地主機位址 127.0.0.1 的回復。
Cause
可使用 localhost 項目在 /etc/hosts 檔案設定不正確。
Resolution
1.以系統管理員身分登入。
2.提升至 root 權限。
3.檢閱主機檔案:
cat /etc/hosts
127.0.0.1 customer.com.mx localhost
::1 customer.com.mx localhost
10.xx.xx.11 cusotmer.com.mx customer
此輸出顯示未正確配置的主機檔。
在 /etc/hosts 中,localhost 的正確組態為:
127.0.0.1 localhost
::1 localhost
4.更新並修正主機檔案。
5.檢閱更新的主機檔案:
cat /etc/hosts
127.0.0.1 localhost
::1 localhost
10.xx.xx.11 cusotmer.com.mx customer
