周末同事急电，马上建数据库。
习惯了图形界面，可是发现远程启动vncserver报错了
[root@localhost ~]# export DISPLAY=:0.0
[root@localhost ~]# xhost +
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified
xhost:  unable to open display ":0.0"

oracle用户下vncserver，然后查看日志：
tail -F /home/oracle/.vnc/localhost.localdomain:1.log
Xvnc: error while loading shared libraries: libstdc++-libc6.1-1.so.2: cannot open shared object file: No such file or directory

用下面的方法解决：
ln -s /usr/lib/libstdc++-libc6.2-2.so.3 /usr/lib/libstdc++-libc6.1-1.so.2

再起vncserver，又查看日志：

网上找了半天资料，都没解决问题，所以就暂时手工建库。

不过这件事情一直困扰着我，今天在老罗的帮助下，终于把问题搞定了。

老罗的方案是：
vncserver -fp /usr/share/fonts/X11/fonts/misc

我的操作是：
[root@localhost ~]# cd /usr/X11R6/lib/
[root@localhost lib]# ls
modules
[root@localhost lib]# ln -s /usr/share/X11 X11
