Linux环境下Spring Boot项目部署脚本详解

重启 restart.sh

#!/bin/bash

# 定义变量
JAR_NAME="xxx.jar"
LOG_DIR="logs/xxx"

# 创建日志目录
mkdir -p "$LOG_DIR"

# 查找占用端口的进程ID
PID=$(ps --no-heading -C java -f --width 1000 | grep $JAR_NAME | awk '{print $2}')

echo "PID: ${PID:-未找到}"

echo "Restarting service..."

# 停止进程
if [ -n "$PID" ]; then
    echo "Stopping existing process (PID: $PID)..."
    kill -9 "$PID" > /dev/null 2>&1
fi

# 等待2秒
sleep 2

# 启动新进程
echo "Starting application..."
nohup java -jar "$JAR_NAME" >> "$LOG_DIR/app.log" 2>&1 &

# 检查是否启动成功
if [ $? -eq 0 ]; then
    echo "Application started successfully"
    echo "PID: $!"
else
    echo "Failed to start application"
    exit 1
fi

# 保持终端不退出
read -p "Press any key to continue..." -n1 -s

停止 stop.sh

#!/bin/bash

JAR_NAME="xxx.jar"

# 获取监听该端口的进程PID
PID=$(ps --no-heading -C java -f --width 1000 | grep $JAR_NAME | awk '{print $2}')

echo "PID: ${PID:-未找到}"

if [ -z "$PID" ]; then
    echo "PID not found. Server may not be running."
else
    echo "Stopping existing process (PID: $PID)..."
    kill -9 "$PID" > /dev/null 2>&1
    # 检查是否成功
    if [ $? -eq 0 ]; then
        echo "Stop Success!"
    else
        echo "Failed to stop the server."
    fi
fi

read -p "Press any key to continue..." -n1 -s

说明，maven打包时，可以将脚本打包跟jar包在同一个目录

   <fileSet>
     <directory>bin/linux</directory>
     <includes>
       <include>restart.sh</include>
       <include>stop.sh</include>
     </includes>
     <outputDirectory>/</outputDirectory>
   </fileSet>
