启动arcgis服务，Unable to start Xvfb on any port in the range 6600 - 6619

1、安装完arcgis 10.2 for server，启动arcgis服务时报错，具体如下
[ags@test81 server]$ ./startserver.sh
Attempting to start ArcGIS Server...
WARNING:

ERROR: Unable to start Xvfb on any port in the range 6600 - 6619.
2、解决方法如下：
[ags@test81 ~]$ find -name xvfb
./arcgis/server/framework/runtime/xvfb
[ags@test81 ~]$cd arcgis/server/framework/runtime/xvfb/
[ags@test81 xvfb]$ ll

/home/ags/arcgis/server/framework/runtime/xvfb/init_Xvfb.sh: line 85: /home/ags/arcgis/server//framework/runtime/xvfb/Ubuntu/Xvfb: 没有那个文件或目录
根据以上提示，打开init_Xvfb.sh，在70行左右
 # fall back to our own
          if [ -f /etc/SuSE-release ]; then
            XVFBBIN="${XVFBHOME}/SuSE/Xvfb"
          elif [ -f /etc/lsb-release ]; then
            XVFBBIN="${XVFBHOME}/Ubuntu/Xvfb"
          else
            XVFBBIN="${XVFBHOME}/RHEL/Xvfb"
          fi
将Ubuntu改为RHEL，保存后，重新启动arcgis服务。
