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
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 > $base_dir/nohup.out 2>&1 "$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总结
