我跟隨http://www.linuxexplorers.com/2014/04/configure-vnc-server-in-red-hat-enterprise-linux-7-rhel7/配置 RHEL 7 VNC 伺服器。
在最後的設定步驟「systemctl start vncserver@:1.service」中，我得到了
Job for vncserver@:1.service failed. See 'systemctl status vncserver@:1.service' and 'journalctl -xn' for details.
journalctl -xn

答案1
由於某些原因，看起來 vncserver 的實例已經在運作。現在為什麼你無法連接可能是一個不同的問題/問題
錯誤訊息會指示您刪除 /tmp 鎖定檔案。按照建議刪除這些訊息，然後重試。
來自同事..
:1 上已經有一個 VNC 伺服器實例正在運行，或先前的 :1 VNC 實例未正確關閉。無論哪種方式，vncserver 都會在/tmp/.X11-unix目錄中檢查並尋找 :1 會話的臨時檔案。
關閉 VNC 伺服器的正確方法是使用vncserver -kill :1.這應該在系統重新啟動之前完成，無論是手動還是在關閉腳本中。
如果沒有正在執行的 VNC 伺服器 :1 實例，請清除該/tmp/.X11-unix目錄並嘗試重新啟動 vncserver。
答案2
Job for vncserver@:7.service failed. See 'systemctl status vncserver@:7.service' and 'journalctl -xn' for details.
刪除該資料夾：
rm -r /tmp/.X11-unix/
它對我有用。
