无法让 Tiger-Vnc 在 Fedora 21 上工作

我已经遵循了两个方向这里和这里。我已经走了很远，但这些指南的最后一个任务是运行systemctl start vncserver@:10.service，但我收到了错误。

当我运行该命令时（其中 10 我认为是所谓的端口偏移量），我收到以下错误：

Job for vncserver@:10.service failed. See "systemctl status vncserver@:10.service" and "journalctl -xe" for details.

sudo我已以和 as用户身份运行该命令root。两次我都得到同样的错误。

总而言之，指南说：

  • yum install tigervnc-server

  • cp/lib/systemd/system/[email protected]/etc/systemd/system/[email protected]

  • 编辑该文件以替换user变量

  • 重新开始 （~]# systemctl daemon-reload）

  • 放vncpasswd

  • 跑步：systemctl enable vncserver@:display_number.service

  • 跑步：systemctl start vncserver@:display_number.service

这是输出systemctrl status vncserver@:10.service

我认为这display_number是“端口偏移”（要添加到 5900 的端口数量），但这是我收到的错误。希望有任何帮助，谢谢。

答案1

您的日志中最相关的行是：

Apr 10 04:47:33 democom runuser[23853]: -bash: /usr/bin/vncserver: /usr/bin/perl: bad interpreter: Permission denied

是否有可能 perl 没有安装在 /usr/bin 中？否则，在执行该 perl 脚本的早期阶段似乎就会出现问题。一种调试方法是获取 systemd 单元文件中正在执行的任何命令并手动执行它，以查看错误是什么。

答案2

检查 /tmp/.X11-unix 目录是否有 X？文件已经存在（？显示#）。如果是，请 rm -f 该文件并重新启动 vncserver。如果没有的话，还有其他东西挡住了路吗？
