是否可以使用Nginx和uWSGI在同一台服务器上运行多个Django站点?
我认为有必要运行多个uWSGI实例(每个站点一个)。我将/etc/init.d/uwsgi复制到uwsgi2并更改了端口号。但是,我收到了以下错误:
# /etc/init.d/uwsgi2 start
Starting uwsgi: /usr/bin/uwsgi already running.
如何运行多个uWSGI实例?

您可以创建多个虚拟主机,允许您托管多个站点,彼此独立。更多信息:http://wiki.nginx.org/VirtualHostExample。
此处还有一些更详细的信息,以及如何设置虚拟主机http://projects.unbit.it/uwsgi/wiki/RunOnNginx#VirtualHosting。

您可以使用Emperor Mode运行多个uwsgi实例。
这将处理新工作器实例的创建。这些实例非常出色地被称为vassals。每个附庸只需要一个配置文件,通常在/etc/uwsgi/vassals
对于nginx,您需要为要提供服务的每个主机创建一个服务器块。只需更改要提供服务的每个主机的server_name
指令即可。这是一个例子:
#Simple HTTP server
server {
listen 80;
root /usr/share/nginx/www;
server_name host1.example.com;
}
#Django server
server {
listen 80;
server_name host2.example.com;
#...upstream config...
}
重要提示:确保您已在/etc/hosts
中指定了主机名。我发现如果不这样做,我的django站点也会在默认服务器IP上提供服务,尽管指定它只应该在我的nginx配置中的特定主机名上提供。

我看到许多建议,比如@ donturner的回答。即在nginx配置文件中设置两个或多个不同的server
。但问题是每个服务器需要一个唯一的server_name
不同的域名或子域名。这种情况怎么样:我想像这样服务两个不同的Django项目:
www.ourlab.cn/site1/ # first Django project
www.ourlab.cn/site2/ # second Django project
通过这种方式,我们可以在一台服务器中配置的所有设置。
这是/etc/nginx/nginx.conf

}
# Django media
location /media {
# your Django project's media files - amend as required
alias /mnt/data/www/metCCS/metCCS/static/media;
}
location /static {
# your Django project's static files - amend as required
# first project's static files path
alias /mnt/data/www/metCCS/metCCS/static/static_dirs;
}
location /static_lip {

alias /mnt/data/www/lipidCCS/lipidCCS/static/static_dirs;
}
# match www.ourlab.cn/metccs/*
location ~* ^/metccs {
include uwsgi_params;
uwsgi_pass unix:/run/uwsgi/metCCS.sock;
}
# match www.ourlab.cn/lipidccs/*
location ~* ^/lipidccs {
include uwsgi_params;
uwsgi_pass unix:/run/uwsgi/lipidCCS.sock;
}
}
您还需要将Django项目的settings.py
文件之一更改为STATIC_URL = '/static_lip/'
,因此两个项目可以分别使用其静态文件。
新发现nginx
可以自行为服务器提供静态文件。即使我们关闭uwsgi和Django,我们也可以通过浏览器使用这些文件。

确实可以,查看http://www.simme.org/blog/2013/05/08/deploying-your-django-projects-with-uwsgi/ - 这是通过uwsgi + nginx部署django项目的演练。
