DISPLAY变量是用来设置将图形显示到何处.比如CENTOS,你用图形界面登录进去,DISPLAY自动设置为DISPLAY=:0.0表示显式到本地监视器.
那么通过终端工具(例如:putty)进去,运行图形界面的程序,如果没有设置,系统是不允许程序启动的.
如果你不想在其他地方显式图形,只是运行一些后台服务程序,那么你需要做一下操作:
export DISPLAY=:0.0
来设置显式方式.
比如上面的xhost +,在设置好DISPLAY之后,就会输出:
[root@localhost lib]# xhost +
access control disabled, clients can connect from any host


另外:使用xdpyinfo这个命令可以查看显式系统的具体信息.
