RHEL 5.1下安装VNC新手教程与常见问题(1)

今天装了下VNC，解决了不少问题，写个教学贴，给新手们看看，如果你们碰到同样的问题，就可以迅速解决，无需头疼甚至放弃了。

系统环境

VM+RHEL5.1
[root@localhost .vnc]# uname -r
2.6.18-53.el5xen

本地XP系统安装VNCVIEW去控制VM中的RHEL5.1

下面在LINUX上安装VNCSERVER

1、去www.realvnc.com去下载免费版for x86 linux

2、下载是一个tar.gz文件，解压后进入文件夹，里面有个README，请注意这块不要下载RPM包，依赖问题以及包头的安全签名会让你很郁闷的。

3、解压缩，进入该文件夹，按照readme 要求执行4步

% ./vncinstall /usr/local/bin
% ./vncinstall /usr/local/bin /usr/local/man
% mkdir -p /usr/local/vnc/classes
% cp java/* /usr/local/vnc/classes

4、启动VNCSERVER，输入连接密码

5、可能会提示linux1x: error while loading shared libraries: libstdc++-libc6.2-2.so.3: cannot open shared object file: No such file or directory

去下载libstdc++-libc6.2-2.so.3，放到/usr/lib里面，这个我碰到了，通过下载这个SO文件解决了）

下面这个方法在这个版本中不可取，我已经试过，是无效的

在我的系统上ls命令的结果是 libstdc++.so.5.0.7 libstdc++.so.6.0.8

libstdc++.so.6.0.8就是我们要找的，给它做个链接

代码:

$ sudo ln -s libstdc++.so.6.0.8 libstdc++-libc6.2-2.so.3

会出现如下错误：

vncpasswd: symbol lookup error:vncpasswd: undefined symbol: __builtin_vec_new

看到这个错感觉就是那两个库不一样造成的字符未定义

6、继续启动vncserver，可能还有错误，如下

vncext: VNC extension running!
vncext: Listening for VNC connections on port 5901
vncext: Listening for HTTP connections on port 5801
vncext: created VNC server for screen 0

Fatal server error:

Warning: This program is an suid-root program or is being run by the root user.

in this environment. You may get a more descriptive message by running the
program as a non-root user or by removing the suid bit on the executable.
xterm Xt error: Can't open display: %s

原因：vncserver默认寻找的X系统的字体路径在/usr/X11R6/lib/X11/fonts/下，但RHEL5却在/usr /share/X11/fonts/下

解决：

mkdir /usr/X11R6/lib
cd /usr/X11R6/lib
ln -s /usr/share/X11 X11
