linux 之 nested exception is java.awt.AWTError: Can’t connect to X11 window server using ‘localhost:10.0’ as the value of the DISPLAY variable.

linux 环境下执行kettle报

nested exception is java.awt.AWTError: Can’t connect to X11 window server using ‘localhost:10.0’ as the value of the DISPLAY variable.

 

1.原因：因为用到了图形处理，java程序会去寻找linux上的图形界面是否启动
2.解决：不让java寻找linux图形界面即可，在java 启动时加选项java -Djava.awt.headless=true 
3.实现：在执行的脚本前加入 export JAVA_OPTS=-Djava.awt.headless=true，即可
