如何使用Jsvc将Java程序作为守护程序启动

Question

I am using Jsvc to start a java program that implements the Daemon interface. However when I issue the command

/usr/bin/jsvc -user walikha -home $JAVE_HOME -outfile out.file -errfile '$1'   Jooist.Server.jar Main

However the command silently executes and displays the prompt. How can I detect if the daemon is running? In the Java executable the init, start, stop and destroy functions just print to a log file using Log4J. The log file is not created and there is absolutely no indication that the service is running. Am I missing something, or have I left out something when configuring and installing Jsvc?

Answer 1

修改命令以包含选项“-outfile”和“-errfile”，并提供自己的日志文件路径。

/usr/bin/jsvc -outfile app.out -errfile app.err -user walikha -home $JAVE_HOME -outfile out.file -errfile '$1'   Jooist.Server.jar Main

Answer 2

Try the -debug switch and see what's going on. However, it looks like you've missed including commons-daemon-1.0.10.jar in your classpath.

Answer 3

您可以通过在/etc/init.d/ start/stop脚本中添加应用程序来启动服务作为守护程序。
