springboot启动脚本start.sh和停止脚本 stop.sh的详细教程

我们在项目中都会遇到项目打包，可以通过assembly对我们的项目进行打包。

针对打包构建jar包，本文不再叙述。具体可以参考maven插件assembly使用及springboot启动脚本start.sh和停止脚本 stop.sh

这里面已经有一个springboot 的启动脚本了，本文之所以还要写，是因为之前的脚本存在一个问题。关闭脚本的时候是通过kill -9 命令进行的，但其实我们项目中可能很多时候不能强制关闭的，在关闭之前需要做一些事情。比如将内存数据存到磁盘，dubbo清空zookeeper里面的固定节点 等等。

这里将启动脚本环境变量抽出来作为一个文件来使用：

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 启动脚本：

#!/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 grhttp://ep | 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 脚本

#!/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 datllzguqa start"

. http://"$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
