我準備將nginx/uwsgi與燒瓶用於我正在開發的網站，但我遇到了問題。注意網站本身運行良好使用燒瓶的調試：5000端口，但我想現在投入生產。解釋我做了什麼。只能以root身份運行uwsgi
這是一個的Linode的Ubuntu 12.04LTS服務器，我安裝了它這樣的：
# 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
然後我開始配置一切，但我已經運行到與uwsgi麻煩（沒關係NGINX，這將是。下一步
sudo nano /etc/uwsgi/apps-available/li.xml
<uwsgi>
<plugin>python</plugin>
<socket>/run/uwsgi/app/li.socket</socket>
<chmod-socket>666</chmod-socket>
<chdir>/srv/www/li</chdir>
<pythonpath>/srv/www/li</pythonpath>
<virtualenv>/srv/www/li/venv</virtualenv>
<module>li</module>
<wsgi-file>/srv/www/li/li.py</wsgi-file>
<callable>app</callable>
<master/>
<processes>4</processes>
<harakiri>60</harakiri>
<reload-mercy>8</reload-mercy>
<cpu-affinity>1</cpu-affinity>
<stats>/tmp/stats.socket</stats>

<reload-on-as>256</reload-on-as>
<reload-on-rss>192</reload-on-rss>
<no-orphans/>
<vacuum/>
</uwsgi>
sudo ln -s /etc/uwsgi/apps-available/li.xml /etc/uwsgi/apps-enabled/li.xml
但是，如果我運行它，我得到：
uwsgi --xml /etc/uwsgi/apps-enabled/li.xml

，所以我得到不允許取消鏈接操作，並且綁定地址已經在使用錯誤（在python_plugin錯誤旁邊，我也沒有線索如何解決這個錯誤！）。如果我作爲sudo運行，它似乎工作正常 - >

任何人都可以請幫助我嗎？由於WWW的數據是www數據組中，他跑了，我嘗試了一些東西：
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
但真的沒有幫助。我也嘗試了一個tcp端口，而不是unix/run/uwsgi/app/port，這兩個端口沒有任何區別... 這讓我很瘋狂:(我希望有人對這裏發生的事情有一點線索
親切的問候，
岩溶

後小評：蟒插件（這是在每個一派示例）在新版本中似乎不再需要。所以最終它確實比我以前想象的更容易和開箱即用！ – Carst 2013-03-03 21:02:38
你能更清楚地知道你的修補程序需要什麼嗎？我的情況完全相同，但我無法破譯我的案例中可重現的內容。 – bearrito 2013-03-06 05:30:38
用我所做的來編輯它！另外：我的工作者的內存限制是真的，所以不要複製:)（與一個沉重的分析過程有關） – Carst 2013-03-06 19:11:39
