我跟随http://www.linuxexplorers.com/2014/04/configure-vnc-server-in-red-hat-enterprise-linux-7-rhel7/配置 RHEL 7 VNC 服务器。
在最后的配置步骤“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
出于某种原因，vncserver 的一个实例似乎已在运行。现在，为什么无法连接可能是另一个问题/问题
错误消息指示您删除 /tmp 锁定文件。按照建议删除这些消息，然后重试。
来自一位同事..
:1 上已有一个 VNC 服务器实例正在运行，或者之前的 :1 VNC 实例未正确关闭。无论哪种情况，vncserver 都会在目录中检查并查找 :1 会话的临时文件/tmp/.X11-unix。
关闭 VNC 服务器的正确方法是使用vncserver -kill :1。这应该在系统重新启动之前完成，可以手动完成，也可以在关机脚本中完成。
如果没有正在运行的 VNC 服务器：1 实例，请清理目录/tmp/.X11-unix并尝试重新启动 vncserver。
答案2
Job for vncserver@:7.service failed. See 'systemctl status vncserver@:7.service' and 'journalctl -xn' for details.
删除此文件夹：
rm -r /tmp/.X11-unix/
这是对我的工作。
