测试uwsgi是否安装成功时，我们一般建一个test.py的文件
# test.py
def application(env, start_response):
start_response('200 OK', [('Content-Type','text/html')])
return "Hello World"
然后执行 uwsgi --http :8000 --wsgi-file test.py
我遇到的问题显示如下：

解决方法：
linux 防火墙开放特定端口(使用iptables命令)：iptables -I -INPUT -p tcp --dport 8000 -j ACCEPT
使8000端口对外开发，浏览器中访问即可看到打印了 Hello World
