如何优雅地重启django在nginx后面运行fcgi？

location / {
    fastcgi_pass 127.0.0.1:8000;
    fastcgi_param PATH_INFO $fastcgi_path_info;
    fastcgi_param REQUEST_METHOD $request_method;
    fastcgi_param QUERY_STRING $query_string;
    fastcgi_param CONTENT_TYPE $content_type;
    fastcgi_param CONTENT_LENGTH $content_length;
    fastcgi_pass_header Authorization;
    fastcgi_intercept_errors off;
}

FCGI_PROTOCOL = 'fcgi'
FCGI_HOST = '127.0.0.1'
FCGI_PORT = 8000

spawn-fcgi -n -u www-data -g www-data -a 127.0.0.1 -p 8000 -P /var/run/fcgi.pid -U /tmp/fcgi.sock -f /path/to/your/django/project/manage.py -C "fcgi" runfcgi

sudo service nginx reload
