#!/bin/sh
jarPath=/usr/java/jar
projectJar=/usr/java/project
echo "============Delete old jar============="
rm -rf ${projectJar}/demo.jar
echo "======Copy the new jar to the running directory======="
cp ${jarPath}/demo.jar ${projectJar}/demo.jar
echo "====================Close the jar process====================="
l=`ps -ef|grep -v grep|grep demo|awk '{print $2}'`
kill -9 $l
echo "================sleep 10s========================="
for i in {1..10}
do
        echo $i"s"
        sleep 1s
done
export BUILD_ID=DontKillMe
echo "====================Start jar====================="
nohup java -jar ${projectJar}/demo.jar & amp;

Apply Script Save

4. Execution

This is implemented immediately

Started successfully

5. Configure a new port number

echo "Deployed directory and project name"
sh /usr/java/test/build.sh
echo "success"

5. Do not package this class

clean package -U -Dmaven.test.skip=true

6. Set script file

#!/bin/bash
echo "Deployed directory and project name"
DIR="/usr/java/project"
projectName="demo"
echo "Application server to be deployed"
server_ips="192.168.158.129"
#All parameter lists
for server_ip in ${server_ips[@]}
do
echo "Perform backup operation"
mkdir -p $DIR/backup/${projectName}
  if [ -f "$DIR/${projectName}/${projectName}.jar" ];then
    mv $DIR/${projectName}/${projectName}.jar $DIR/backup/${projectName}/${projectName}-`date " + %Y%m%d_%H%M%S"` .jar
  fi
echo "Copy the jar package to the directory of the target server"
cp ${WORKSPACE}/target/*.jar $DIR/${projectName}/${projectName}.jar

echo "Target server:$DIR/${projectName}/${projectName}.jar"

echo "Connect for publishing operation"
#mv /usr/java/test/demo.jar $DIR/backup/${projectName}/${projectName}.jar
echo "Start closing jar"
l=`ps -ef|grep demo.jar|grep -v grep|awk '{print $2}'`
for i in $l
do
 kill -9 $i
done
sleep 5s
echo "start jar"
nohup java -jar $DIR/${projectName}/${projectName}.jar --server.port=9999 > release_out.log 2> & amp;1 & amp;start_ok=false
done
