在Linux 上將Java 應用程式作為服務運行

為了確保Linux 上Java 伺服器應用程式的連續運行和輕鬆管理，通常需要將它們作為服務運行。本指南探討了滿足這些要求的解決方案。

服務需求

在虛擬託管Linux 環境中，Java 應用程式可以手動啟動或透過諸如rc.local，但這種方法缺乏無縫維護所需的靈活性和控制力。要獨立於伺服器重新啟動來管理應用程序，請考慮將它們作為服務運行。

創建服務腳本

要創建服務腳本，請按照以下步驟操作：

#!/bin/sh
SERVICE_NAME=your_service_name
PATH_TO_JAR=full_path_to_jar_file
PID_PATH_NAME=/tmp/your_service_name-pid
case  in
    start)
        echo "Starting $SERVICE_NAME ..."

        # Check if service is already running
        if [ ! -f $PID_PATH_NAME ]; then

            # Execute Java command in the background (daemonize)
            nohup java -jar $PATH_TO_JAR > /tmp/service_name.log 2>&amp;1 &amp;

            # Store PID to track process
            echo $! > $PID_PATH_NAME
            echo "$SERVICE_NAME started ..."
        else
            echo "$SERVICE_NAME is already running ..."
        fi
    ;;
    stop)
        # Check if PID file exists to ensure service is running
        if [ -f $PID_PATH_NAME ]; then
            PID=$(cat $PID_PATH_NAME)
            echo "$SERVICE_NAME stopping ..."

            # Kill process
            kill $PID
            echo "$SERVICE_NAME stopped ..."

            # Remove PID file
            rm $PID_PATH_NAME
        else
            echo "$SERVICE_NAME is not running ..."
        fi
    ;;
    restart)
        # Stop service
        if [ -f $PID_PATH_NAME ]; then
            PID=$(cat $PID_PATH_NAME)
            echo "$SERVICE_NAME stopping ..."
            kill $PID
            echo "$SERVICE_NAME stopped ..."
            rm $PID_PATH_NAME
        else
            echo "$SERVICE_NAME is not running ..."
        fi

        # Start service
        echo "$SERVICE_NAME starting ..."
        nohup java -jar $PATH_TO_JAR > /tmp/service_name.log 2>&amp;1 &amp;
        echo $! > $PID_PATH_NAME
        echo "$SERVICE_NAME started ..."
    ;;
