這篇文章主要介紹了springboot啟動腳本start.sh和停止腳本 stop.sh的詳細(xì)教程,本文給大家介紹的非常詳細(xì)，對大家的學(xué)習(xí)或工作具有一定的參考借鑒價值，需要的朋友可以參考下

我們在項目中都會遇到項目打包，可以通過assembly對我們的項目進(jìn)行打包。
針對打包構(gòu)建jar包，本文不再敘述。具體可以參考maven插件assembly使用及springboot啟動腳本start.sh和停止腳本 stop.sh

這里面已經(jīng)有一個springboot 的啟動腳本了，本文之所以還要寫，是因為之前的腳本存在一個問題。關(guān)閉腳本的時候是通過kill -9 命令進(jìn)行的，但其實我們項目中可能很多時候不能強(qiáng)制關(guān)閉的，在關(guān)閉之前需要做一些事情。比如將內(nèi)存數(shù)據(jù)存到磁盤，dubbo清空zookeeper里面的固定節(jié)點(diǎn) 等等。

這里將啟動腳本環(huán)境變量抽出來作為一個文件來使用：

setenv.sh

#!/usr/bin/env bash

PIDFILE=server.pid

if [ "$JAVA_HOME" != "" ]; then
 JAVA="$JAVA_HOME/bin/java"
 else
 JAVA=java
 fi

 JAVA_OPTS="-server -Xms32m -Xmx32m -Xmn24m -Xss256K -XX:MetaspaceSize=10m -DHADOOP_USER_NAME=root
   -XX:SurvivorRatio=4 -XX:+UseConcMarkSweepGC \
   -XX:+UseCMSCompactAtFullCollection -XX:CMSFullGCsBeforeCompaction=10 \
   -XX:CMSInitiatingOccupancyFraction=60 -XX:+AggressiveOpts \
   -XX:+UseFastAccessorMethods \
	 -XX:+HeapDumpOnOutOfMemoryError \
	 -XX:HeapDumpPath=$base_dir/dump.dump
   -XX:+PrintGCDateStamps -XX:+PrintGCDetails \
   -Xloggc:$base_dir/gc.log"

start.sh 啟動腳本：

#!/usr/bin/env bash
#source $(dirname $0)/../../env.sh
SERVERJAR="database-project-0.0.1-SNAPSHOT.jar"
base_dir=$(dirname $0)
cd ..
	
if [ -r "$base_dir/setenv.sh" ]; then
 . "$base_dir/setenv.sh"
fi

PID=$(ps -ef | grep "$SERVERJAR" | grep -v grep | awk '{ print $2}')

if [ -z "$PID" ]; then
 echo "Application has already stopped."
else
 echo "kill $PID"
 kill $PID && echo "Send stopping signal to server successful."


 #wait server stop

 LOOPS=0
 while(true)
 do
  PID=$(ps -ef | grep "$SERVERJAR" | grep -v grep | awk '{print $2}')
  if [ -z "$PID" ]; then
   echo "Stop server successful! Cost $LOOPS seconds."
   break;
  fi
  #judge time out

  if [ "$LOOPS" -gt 180 ]; then
   echo "$Stop server cost time over 180 seconds. Now force stop it."
   kill -9 $PID && echo "Force stop successful."
   break;
  else
   echo "Cost $LOOPS seconds."
  fi

  let LOOPS=LOOPS+1
  sleep 1
 done
fi

echo `pwd`
echo $SERVERJAR
echo $JAVA
echo $JAVA_OPTS
echo $JAVA_DEBUG_OPT

nohup $JAVA $JAVA_OPTS -jar $base_dir/../lib/$SERVERJAR > $base_dir/nohup.out 2>&1 < /dev/null &

if [ $? -eq 0 ]; then
 echo -n $! > "$PIDFILE"
 if [ $? -eq 0 ]; then
  sleep 1
  echo "STARTED"
 else
  echo "FAILED TO WRITE PID"
  exit 1
 fi
else
 echo "SERVER DID NOT START"
 exit 1
fi

stop.sh 腳本

#!/usr/bin/env bash
#source $(dirname $0)/../../env.sh
SERVERJAR="database-project-0.0.1-SNAPSHOT.jar"
base_dir=$(dirname $0)
cd ..
	
if [ -r "$base_dir/setenv.sh" ]; then
	 echo -e "come get data start"
 . "$base_dir/setenv.sh"
	echo -e "come get data end "
fi

PID=$(ps -ef | grep "$SERVERJAR" | grep -v grep | awk '{ print $2}')

if [ -z "$PID" ]; then
 echo "Application has already stopped."
else
 echo "kill $PID"
 kill $PID && echo "Send stopping signal to server successful."


 #wait server stop

 LOOPS=0
 while(true)
 do
  PID=$(ps -ef | grep "$SERVERJAR" | grep -v grep | awk '{print $2}')
  if [ -z "$PID" ]; then
   echo "Stop server successful! Cost $LOOPS seconds."
   break;
  fi
  #judge time out

  if [ "$LOOPS" -gt 180 ]; then
   echo "$Stop server cost time over 180 seconds. Now force stop it."
   kill -9 $PID && echo "Force stop successful."
   break;
  else
   echo "Cost $LOOPS seconds."
  fi

  let LOOPS=LOOPS+1
  sleep 1
 done
fi
