实验linux是vmware上的rhel6.0，安装的是centos社区桌面，ip:192.168.31.223，win设置的固定ip:192.168.31.166，且远程ssh软件用的是SecureCRT
需要提前设置sshd_config开放x11转发，以及在SecureCRT（会话选项里）上同样开放。
[root@ton ~]#export DISPLAY=192.168.31.166:0.0 #连接到win的ip，可以写到bashrc上固定
[root@ton ~]#xeyes
[root@ton ~]#xeyes
No protocol specified
Error: Can't open display: 192.168.31.166:0.0
这里需运行XLaugch，且最后一步配置，选No Access Control。
[root@ton ~]#xclock
#若出现 Warning: Missing charsets in String to FontSet conversion
#则 export LANG=C
