使用monit监视java程序

Question

我写信是为了通过Monit开始我的java程序获得一些帮助。 我写了一个启动脚本program.sh。 这个帖子给出了monit代码和scipt代码。

问题是我无法使用monit执行的脚本文件启动和停止程序。 如果我使用终端启动它，我可以监控进程，但我不能用monit启动/停止它。 来自monit的日志说“启动失败”

但是，我可以从monit开始和停止像ssh easliy这样的程序。 monit在sudo下运行，我从具有管理权限的帐户运行脚本。 如果有人帮我解决这个问题，那将非常有帮助谢谢

monitrc文件

启动/停止脚本

       echo $$ > javaprg.pid;
       exec /usr/bin/java -jar javaprg.jar
       ;;

 esac
 exit 0

Answer 1

您应该在起始停止脚本中设置绝对路径。

您可以尝试使用rooted shell sudo -s启动它。

你应该使用/etc/monit/conf.d文件夹来/etc/monit/conf.d你的conf文件。

Answer 2

当我尝试在Monit下配置shell脚本时遇到了同样的问题。 解决问题的方法是在程序本身之前使用/ bin / sh。

尝试使用：

start program = "/home/user/Desktop/Binaries/javaprg.sh start"

stop program = "/home/user/Desktop/Binaries/javaprg.sh stop"

Answer 3

我使用你的脚本遇到了同样的问题，这是因为启动脚本没有指定保存PID的位置。 它将javaprg.pid保存到/然后保存到主文件夹。 将启动脚本更改为'echo $$ > /home/usr/binaries/javaprg.pid' ，它将起作用。
