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.

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

中放置(或符号链接)

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

中的设置
# For more information on configuration, see:

#   * Official Russian Documentation: http://nginx.org/ru/docs/

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

# Load dynamic modules. See /usr/share/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;

events {
    worker_connections 1024;
}

http {
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 2048;

    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;

    # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include
    # for more information.
    include /etc/nginx/conf.d/*.conf;

    server {
        listen       80 default_server;
        listen       [::]:80 default_server;
        server_name  _;
        root         /usr/share/nginx/html;

        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;

        location / {
        }

        error_page 404 /404.html;
            location = /40x.html {
        }

        error_page 500 502 503 504 /50x.html;
            location = /50x.html {
        }
    }

}

这是/etc/nginx/conf.d/self_configure.conf

中的设置
# /etc/nginx/conf.d/self_configure.conf
server {
    listen       80;
    server_name  www.ourlab.cn;

    # note that these lines are originally from the "location /" block
    root   /mnt/data/www/ourlab;
    index index.php index.html index.htm;

    location / {
        try_files $uri $uri/ =404;
    }
    error_page 404 /404.html;
    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
        root /usr/share/nginx/html;
    }

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }

    # 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 {
        # second project's static files path
        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。
