requirements

  • VirtualBox
  • Vagrant

start vm

## 克隆代码
git clone git@gitee.com:dyrnq/seckill.git
cd seckill

## 启动虚拟机
vagrant up seckill

## ssh登录虚拟机
vagrant ssh seckill

# 如果报错 vagrant@127.0.0.1: Permission denied (publickey). 
# 执行 set VAGRANT_PREFER_SYSTEM_BIN=0

## 切换用户为root,root密码为vagrant
su --login root

## 安装必备软件
cd /vagrant && bash ./install.sh

build

./mvnw clean package -Dmaven.test.skip=true -s ./settings.xml

run

选项一(运行main函数)

直接运行 com.dyrnq.seckill.SeckillApplicationmain函数

选项二(运行spring-boot:run)

./mvnw spring-boot:run

选项三(打包后运行java -jar)

javar \
-server \
-Djava.awt.headless=true \
-Dfile.encoding=UTF-8 \
-Duser.timezone=Asia/Shanghai \
-Djava.net.preferIPv4Stack=true \
-jar target/seckill-0.0.1-SNAPSHOT.jar \
--server.port=8080

如果在一个机器启动多实例需要修改--server.port=以避免端口冲突
