springboot启动脚本start.sh和停止脚本 stop.sh的详细教程
作者：筏镜
这篇文章主要介绍了springboot启动脚本start.sh和停止脚本 stop.sh的详细教程,本文给大家介绍的非常详细，对大家的学习或工作具有一定的参考借鉴价值，需要的朋友可以参考下
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 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 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 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
