使用監控監控一個java程序

Question

我正在寫關於通過Monit啓動我的java程序的一些幫助。我寫了一個啓動腳本program.sh。 monit代碼和scipt代碼在本文中給出。

問題是我無法使用通過monit執行的腳本文件啓動和停止程序。如果我使用終端啓動它，我可以監視該過程，但無法用monit啓動/停止它。來自monit的日誌顯示「無法啓動」

但是，我可以從monit啓動和停止像ssh easliy這樣的程序。 monit在sudo下運行，我從具有管理權限的帳戶運行腳本。 它將如果有人幫助非常有幫助我弄清楚了這一點 感謝

monitrc文件

啓動/停止腳本

#!/bin/bash 
case $1 in 
    start) 
     echo $$ > javaprg.pid; 
     exec /usr/bin/java -jar javaprg.jar 
     ;; 
    stop) 
     kill $(cat javaprg.pid); 
     rm javaprg.pid 
     ;; 
    *) 
     echo "usage: javaprg {start|stop}" ;; 
esac 
exit 0 

Answer 1

你應該設定絕對路徑在你開始停止腳本。

您可以嘗試使用有根的外殼sudo -s啓動它。

而且你應該使用/etc/monit/conf.d文件夾將你的conf文件合併。

Answer 2

我在嘗試在Monit下配置shell腳本時遇到了同樣的問題。 解決問題的方法是在程序本身之前使用/ bin/sh。

嘗試使用：

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

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

Answer 3

我不得不使用你的腳本同樣的問題，這是因爲啓動腳本沒有指定保存的PID。它將javaprg.pid保存到/而不是主文件夾。將開始腳本更改爲'echo $$ > /home/usr/binaries/javaprg.pid'，它將起作用。
