Linux服务器init 5启动图形界面，报错Retrigger failed udev events的解决方法

1.开启linux系统的桌面环境，使用startx未成功，报如下错误：

提示：Retrigger failed udev events

[root@5201351 /]# startx
xauth:  creating new authority file /root/.serverauth.2002

xinit:  No such file or directory (errno 2):  no server "/usr/bin/X" in PATH

Use the -- option, or make sure that /usr/bin is in your path and
that "/usr/bin/X" is a program or a link to the right type of server
for your display.  Possible server names include:

Xorg        Common X server for most displays
Xvfb        Virtual frame buffer
Xfake       kdrive-based virtual frame buffer
Xnest       X server nested in a window on another X server
Xephyr      kdrive-based nested X server

giving up.
xinit:  No such file or directory (errno 2):  unable to connect to X server
xinit:  No such process (errno 3):  Server error.

再继续使用init 5命令进行切换时，同样报错Retrigger failed udev events，如下图所示：



这是因为init 5执行的条件是得linux操作系统得有图形环境，因此很可能是未安装桌面环境

解决方法，安装Gnome桌面环境即可：

[root@5201351 ~]yum groupinstall "Desktop"  -y
[root@5201351 ~]yum groupinstall "X Window System"  -y

安装时间比较长.
