如何防止 Java 进程被 killall java -9 杀死

如何防止 Java 进程被 killall java -9 杀死

每当我输入 killall java -9 时,所有 java 进程都会被终止,即使我更改了进程名称。那么有没有办法保护 java 进程不被“killall java -9”终止

答案1

简单的解决办法是使用不同的用户运行该进程. 那么,您(作为您当前的用户)将无权终止所有名为 的进程java,除非您是root


我,,deltik没有正在java运行的进程。 top显示:

这是我尝试时的输出killall -9 java

Deltik-iMac:~ deltik$ killall -9 java
