執行DBCA,NETCA報如下錯誤故障處理
Xlib:connection to “:0.0” refused by server
故障現象:
故障分析:
從故障現象來看是由于xhost問題導緻,通常是需要遠端執行彈出視窗的時候将會發生該錯誤,例如,我們通過指令行輸入dbca指令的時候由xmanger來輸出圖形界面的時候會彈出該錯誤。
解決改問題步驟如下:
1、用root登陸linux,啟動vnc服務;
2、根據vnc起來的端口,設定export DISPLAY=localhost:1(1表示vnc在第一個tty上啟動的),vnc的啟動資訊如下:
[root@localhost ~]# vncserver
New 'localhost:1 (root)' desktop is localhost:1
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/localhost:1.log
[root@localhost ~]# export DISPLAY=localhost:1
[root@localhost ~]# xhost
access control disabled, clients can connect from any host
[root@localhost ~]# vncserver New 'localhost:1 (root)' desktop is localhost:1 Starting applications specified in /root/.vnc/xstartup Log file is /root/.vnc/localhost:1.log [root@localhost ~]# export DISPLAY=localhost:1 [root@localhost ~]# xhost access control disabled, clients can connect from any host
3、執行xhost ,并且提示“access control disabled, clients can connect from any host”才正确。
