设置django以使用uwsgi我可以使用virtualenv之外的命令uwsgi --ini kb_uwsgi.ini --http :8000来运行它但是尝试运行emperor命令sudo uwsgi --emperor /etc/uwsgi/vassals --uid www-data --gid www-data会带来错误：
ubuntu@ip-172-31-16-133:/etc/uwsgi/vassals$ ls
kb_uwsgi.ini
ubuntu@ip-172-31-16-133:/etc/uwsgi/vassals$ sudo uwsgi --emperor /etc/uwsgi/vassals --uid www-data --gid www-data

这是uwsgi文件
# kb_uwsgi.ini file
[uwsgi]
http = :80
# Django-related settings
# the base directory (full path)
chdir = /home/ubuntu/webapps/kenyabuzz
# Django's wsgi file
module = kb.wsgi
# the virtualenv (full path)
home = /home/ubuntu/webapps/djangoenv
# process-related settings
# master
master = true
# maximum number of worker processes
processes = 10
# the socket (use the full path to be safe
socket = /tmp/kb.sock
# ... with appropriate permissions - may be needed
chmod-socket = 664
# clear environment on exit
#vacuum = true
答案 0 :(得分：0)
在uwsgi文件中配置了http端口80。默认情况下，不允许普通用户绑定到此端口。这就是为什么您得到bind(): Permission denied的原因。您可以give permission给www数据用户使用该端口，也可以使用其他端口。
