linux 脚本 启动服务,一个启动，停止，重启微服务的shell脚本例子

在做微服务的时候，需要定制一个shell脚本，类似标准linux 命令那样通过start, stop， restart 去启动应用等操作， 这里收集了一个脚本，可以参考。#!/bin/sh

## java env

export JAVA_HOME=/usr/local/java/jdk1.7.0_72

export JRE_HOME=$JAVA_HOME/jre

## service name

APP_NAME=user

SERVICE_DIR=/home/wusc/edu/service/$APP_NAME

SERVICE_NAME=edu-service-$APP_NAME

JAR_NAME=$SERVICE_NAME\.jar

PID=$SERVICE_NAME\.pid

cd $SERVICE_DIR

case "$1" in

start)

nohup $JRE_HOME/bin/java -Xms256m -Xmx512m -jar $JAR_NAME >/dev/null 2>&1 &

echo $! > $SERVICE_DIR/$PID

echo "=== start $SERVICE_NAME"

;;

stop)

kill `cat $SERVICE_DIR/$PID`

rm -rf $SERVICE_DIR/$PID

echo "=== stop $SERVICE_NAME"

sleep 5

##

## edu-service-aa.jar

## edu-service-aa-bb.jar

P_ID=`ps -ef | grep -w "$SERVICE_NAME" | grep -v "grep" | awk '{print $2}'`

if [ "$P_ID" == "" ]; then

echo "=== $SERVICE_NAME process not exists or stop success"

else

echo "=== $SERVICE_NAME process pid is:$P_ID"

echo "=== begin kill $SERVICE_NAME process, pid is:$P_ID"

kill -9 $P_ID

fi

;;

restart)

$0 stop

sleep 2

$0 start

echo "=== restart $SERVICE_NAME"

;;

*)

## restart

$0 stop

sleep 2

$0 start

;;

esac

exit 0
