shell常用脚本

1、Java项目重启脚本

#!/bin/bash

# 定义一个函数来结束进程和启动新进程
function restart(){
  JAR_NAME=$1  # jar包
  LOG_NAME=$2  # 日志
  JVM_ARGS=$3  # jvm 参数

  PID=$(ps -ef | grep java | grep ${JAR_NAME} | awk '{ print $2 }')

  if [[ ! -z "$PID" ]]; then
    echo "Killing old process [${JAR_NAME}] with pid ${PID}"
    kill -9 $PID
  fi

  echo "Starting new process [${JAR_NAME}]"
  nohup java ${JVM_ARGS} -jar /home/seres-wms/${JAR_NAME}.jar --spring.profiles.active=dev > /home/seres-wms/${LOG_NAME}.log 2>&1 &
}

# 现在我们使用上面的函数来管理每个Jar文件
restart "seres-gateway" "seres-gateway" "-Xmn1000m -Xms1500m -Xmx1500m -XX:SurvivorRatio=8"
restart "seres-module-core-biz" "seres-core" "-Xmn1500m -Xms2000m -Xmx2000m -XX:SurvivorRatio=10"
restart "seres-module-system-biz" "seres-system" "-Xmn1000m -Xms1500m -Xmx1500m -XX:SurvivorRatio=8"

目录结构如下：其中log文件是自动生成
