不能访问
原因一：防火墙未关闭
service firewalld stop 关闭防火墙
systemctl status firewall 状态为关闭状态
(flask_mini) [root@VM_0_13_centos order]# systemctl status firewalld ● firewalld.service - firewalld - dynamic firewall daemon Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled) Active: inactive (dead) Docs: man:firewalld(1)
原因二：云服务器的安全组，为开启5000端口
