## sh 脚本模板 ##

该模板，每次运行一次都会 kill 掉原来的服务，然后重新启动 jar 包服务

#!/bin/bash
    
    # 定义Java进程的名称
    APP_NAME=your-app-name.jar
    
    # 定义Java进程的日志文件路径
    LOG_PATH=/var/log/your-app-name.log
    
    # 定义备份日志文件的目录
    BACKUP_DIR=/var/log/backup
    
    # 定义Java进程的启动参数
    JAVA_OPTS="-Xmx1024m -Xms1024m -XX:MaxPermSize=256m"
    
    # 检查Java进程是否存在
    PID=$(ps -ef | grep ${
         APP_NAME} | grep -v grep | awk '{print $2}')
    if [[ -n ${PID} ]]; then
      echo "Java process is running, PID is ${PID}. Killing..."
      kill -9 ${PID}
    fi
    
    # 检查日志文件是否存在
    if [[ -f ${LOG_PATH} ]]; then
      echo "Log file exists. Backing up..."
      if [[ ! -d ${BACKUP_DIR} ]]; then
        mkdir ${BACKUP_DIR}
      fi
      cp ${LOG_PATH} ${BACKUP_DIR}/$(date +%Y%m%d%H%M%S).log
      echo "Log file backed up to ${BACKUP_DIR}."
    fi
    
    # 启动Java进程
    nohup java ${JAVA_OPTS} -jar ${APP_NAME} > ${LOG_PATH} 2>&1 &
    
    # 检查Java进程是否启动成功
    sleep 10
    PID=$(ps -ef | grep ${
         APP_NAME} | grep -v grep | awk '{print $2}')
    if [[ -n ${PID} ]]; then
      echo "Java process started successfully, PID is ${PID}."
    else
      echo "Failed to start Java process."
    fi
