Package the springboot project
Upload to server
Put the jar package just packed in the corresponding directory
Alibaba Cloud open port 9000 (9000 I wrote above)
Jump to the directory where you just put the jar package, and enter the following commands in the command line
firewall-cmd --zone=public --add-port=9000/tcp --permanent # 开端口
systemctl restart firewalld.service # 重启服务器
firewall-cmd --list-ports # 查看该端口是否开放
nohup java -jar demo-0.0.1-SNAPSHOT.jar >/dev/null 2>&1 & # 发布项目（名字为刚刚jar包的名字）
Enter [ip address+port number+interface] in the address bar to view
