p.s: 环境是ubuntu16.04，项目的目录是/home/alps/mysite

# uwsgi启动正常
uwsgi -i uwsgi.ini

/home/alps/mysite/uwsgi.ini配置文件如下

[uwsgi]
socket = 127.0.0.1:8001
chdir=/home/alps/mysite/
wsgi-file = mysite/wsgi.py

processes = 2
threads = 4

chmod-socket = 664

/etc/nginx/sites-enabled/mysite.conf的配置文件如下

server{
    location / {
        listen 80;
        uwsgi_pass 127.0.0.1:8001 
        include     /etc/nginx/uwsgi_params;
    }
}

下面是报错信息

$ sudo service nginx configtest

$ systemctl restart nginx.service

请问"location /"为什么是unknown directive呢？
