使用方式

新建 a.sh文件
复制脚本代码进去注意文件权限 chmod +x a.sh
./a.sh start 启动 ./a.sh stop 停止 ./a.sh restart 重启

启动程序里面：

nohup java -Dfile.encoding=utf-8 -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/devdata/gcapp/heapError -jar $JAR_FILE --spring.profiles.active=prod --spring.cloud.nacos.server-addr=192.168.10.185:8848 --spring.cloud.nacos.config.server-addr=192.168.10.185:8848 > $LOG_FILE 2>&1 &

这里配置的比较多参数一般简单的：

   nohup java -jar $JAR_FILE > $LOG_FILE 2>&1 &

#!/bin/bash

# 应用程序的JAR文件名
JAR_FILE="operate-server.jar"
LOG_FILE="operate.log"

# 获取应用程序的PID
get_pid() {
    echo $(ps -ef | grep $JAR_FILE | grep -v grep | awk '{print $2}')
}

# 启动应用程序
start() {
    if [ -z "$(get_pid)" ]; then
        echo "Starting $JAR_FILE..."
        nohup java -Dfile.encoding=utf-8 -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/devdata/gcapp/heapError -jar $JAR_FILE --spring.profiles.active=prod --spring.cloud.nacos.server-addr=192.168.10.185:8848 --spring.cloud.nacos.config.server-addr=192.168.10.185:8848 > $LOG_FILE 2>&1 &
        echo "$JAR_FILE started with PID $(get_pid) and logging to $LOG_FILE"
    else
        echo "$JAR_FILE is already running with PID $(get_pid)"
    fi
}

# 停止应用程序
stop() {
    PID=$(get_pid)
    if [ -n "$PID" ]; then
        echo "Stopping $JAR_FILE with PID $PID..."
        kill $PID
        sleep 2
        if [ -z "$(get_pid)" ]; then
            echo "$JAR_FILE stopped."
        else
            echo "Failed to stop $JAR_FILE. Forcing stop..."
            kill -9 $PID
            echo "$JAR_FILE forcefully stopped."
        fi
    else
        echo "$JAR_FILE is not running."
    fi
}

# 根据传入的参数执行相应的操作
case "$1" in
    start)
        start
        ;;
    stop)
        stop
        ;;
    restart)
        stop
        start
        ;;
    *)
        echo "Usage: $0 {start|stop|restart}"
        exit 1
        ;;
esac

exit 0
