今天在一台Linux虚拟机上安装了一个ArcGIS Server For Linux(只ArcSOC)组件，一切正常，但是启动服务的时候报一下的错误：

[root@rhsde scripts]# ./startserver

is shut down.  Please run the stopmonitor to shutdown this process
if necessary.

从错误上看是无法启动Xvfb进程，具体原因不详，到$AGSHOME/servercore/.Server/Init_Xvfb.sh中查看启动Xvfb的函数，修改ags_xvfb_log变量到/tmp/xvfb.log，将错误信息记录到/tmp/xvfb.log文件中。再次启动服务，发现xvfb.log中记录如下信息：



Cannot establish any listening sockets - Make sure an X server isn't already running
Couldn't open RGB_DB '/usr/X11R6/lib/X11/rgb'
_XSERVTransSocketUNIXCreateListener: ...SocketCreateListener() failed

Fatal server error:

原来是X Server已经启动了一个实例，到/tmp将 .X11-unix目录删除掉，继续启动服务，还是报同样的错误，继续查看/tmp/xvfb.log文件，发现错误发生了如下的变化：

Couldn't open RGB_DB '/usr/X11R6/lib/X11/rgb'
_XSERVTransmkdir: Owner of /tmp/.X11-unix should be set to root

原来是缺少文件，从别的机器上将这些文件拷贝过来后，重启启动服务后，成功。在此简记一下。
