我正在准备使用Nginx / uwsgi与烧瓶我正在开发的网站,但我遇到问题.注意,网站本身运行良好使用烧瓶的调试：5000端口,但我现在想投入生产.解释我做了什么

它是一个linode ubuntu 12.04LTS服务器,我安装它像这样：

# install Nginx

sudo apt-get install python-software-properties

sudo add-apt-repository ppa:Nginx/stable

sudo apt-get update

sudo apt-get upgrade --show-upgraded

sudo apt-get install Nginx-full

# installing uwsgi

sudo apt-get install build-essential python-dev libxml2-dev

sudo apt-get install libc6 libexpat1 libgd2-xpm libgeoip1 libpam0g libpcre3 libssl1.0.0 libxml2 libxslt1.1 zlib1g

sudo pip install uwsgi

# python basics

sudo apt-get install python-pip build-essential python-dev

sudo pip install virtualenv

sudo pip install virtualenvwrapper

sudo mkdir -p /srv/www/li/

cd /srv/www/li/

virtualenv venv

source /srv/www/li/venv/bin/activate

pip install flask

然后我开始配置一切,但我已经遇到麻烦与uwsgi(不介意Nginx,这将是下一步.

sudo nano /etc/uwsgi/apps-available/li.xml

cpu-affinity>1cpu-affinity>

RSS>192RSS>

但是,如果我运行它,我得到：

uwsgi --xml /etc/uwsgi/apps-enabled/li.xml

open("./python_plugin.so"): No such file or directory [core/utils.c line 4755]

谁能帮帮我吗？由于www数据在www数据组中,他运行它,我尝试了一些东西：

sudo usermod -a -G www-data $USER

sudo chown -R $USER:www-data /srv/www/li

sudo chmod -R g+r+w+x /srv/www/li

sudo chown -R $USER:www-data /etc/uwsgi/apps-enabled

sudo chmod -R g+r+w+x /etc/uwsgi/apps-enabled

sudo chown -R $USER:www-data /run/uwsgi/app

sudo chmod -R g+r+w+x /run/uwsgi/app

但这真的没有帮助.我也尝试了一个tcp端口,而不是unix / run / uwsgi / app / port,没有任何区别…

这让我疯狂:(我希望有人对这里发生的事情有一个线索.

亲切的问候,

CARST

编辑：服务器重新启动后仍然给出一个错误,但是不同的：
