问题说明
在安装部署过程中，设置了知识库连接及其它配置项，重启时可能报如下错误：Caused by: java.lang.InternalError: Can't connect to X11 window server using '10.9.0.117:0.0' as the value of the DISPLAY variable，原因是程序检测到当前系统没有启动图形界面所致。
解决方法
让程序不去检测当前图形用户界面是否已经启动即可。我们直接修改 Java 虚拟机的 JVM 参数，添加如下参数项，具体可参考wiki文档：应用服务器配置建议(JVM参数)
-Djava.awt.headless=true
