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
但是,如果我运行它,我得到：
uwsgi --xml /etc/uwsgi/apps-enabled/li.xml
[uWSGI] parsing config file /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：

最佳答案
这一直是我在谷歌的第一个结果,这个页面对我来说相对没有帮助,所以我要补充一下我的答案,尽管回想起来是相当明显的.
我的问题是我的stats socket的权限问题.如果您更改uWSGI配置的uid或gid参数,请确保您使用chmod或rm所有旧套接字/ pid及其父文件夹. （编辑：大庆站长网）
