spring boot jar 分离自动部署脚本

背景

远程部署时spring boot 包，比较大。可以采用依赖库和业务包分离的方式。提供一个脚本进行自动部署

maven 配置分离jar包

部署脚本

bash 复制代码

#!/bin/bash

AppName="smart_engineering_admin.jar"
RemoteUser="root"
RemoteHost="xxx.xxx.xxx.xxx"
JVM_OPTS=" -Dloader.path=smart_engineering/lib -Dserver.port=8080 -Dname=$AppName  -Dfile.encoding=UTF-8 -Dsun.jnu.encoding=UTF-8 -Duser.timezone=Asia/Shanghai -Xms512m -Xmx1024m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=512m -XX:+HeapDumpOnOutOfMemoryError -XX:+PrintGCDateStamps  -XX:+PrintGCDetails -XX:NewRatio=1 -XX:SurvivorRatio=30 -XX:+UseParallelGC -XX:+UseParallelOldGC"

start() {
    echo "Starting $AppName on $RemoteHost"

    # 定义一个内嵌的函数来远程查询 PID
    query() {
        ssh "${RemoteUser}@${RemoteHost}" "ps -ef | grep java | grep '$AppName' | grep -v grep | awk '{print \$2}'"
    }

    # 获取远程进程 ID
    PID=$(query)

    if [ -n "$PID" ]; then
        echo "$AppName is already running on $RemoteHost (pid: $PID)..."
    else

        echo "$AppName started successfully on $RemoteHost."
        ssh "${RemoteUser}@${RemoteHost}" "tail -f logs/sys-console.log"
    fi
}

sync() {
    rsync -avc --delete ruoyi-admin/target/lib/ root@140.143.209.33:smart_engineering/lib
    scp ruoyi-admin/target/smart_engineering_admin.jar root@140.143.209.33:smart_engineering/
}

stop() {

    # 定义一个内嵌的函数来远程查询 PID
    query() {

    }

    # 获取进程 ID
    PID=$(query)

    if [ -n "$PID" ]; then

        ssh "${RemoteUser}@${RemoteHost}" "kill -TERM $PID"

        # 等待进程退出
        while [ -n "$PID" ]; do
            sleep 1
            PID=$(query)
        done
        echo "$AppName has exited."
    else
        echo "$AppName is already stopped."
    fi
}



sync
stop
sleep 2
start

优点
- 依赖包不变化不会同步，减少上传的文件
- 每次都同步业务包，保证准确性
- 提升发布速度

要求

windows 的wsl下可用
需要和服务器配置ssh互信

进一步封装
