Przygotowuję się do użycia nginx/uwsgi z kolbą do strony, którą rozwijam, ale mam problemy. Uwaga: sama strona działa doskonale przy użyciu debugowania kolby: 5000 portów, ale teraz chcę rozpocząć produkcję. Aby wyjaśnić, co zrobiłem.Może uruchamiać tylko uwsgi z korzeniem
Jest to Linode ubuntu serwer 12.04LTS, zainstalowałem go tak:
# 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
Potem określone skonfigurować wszystko, ale ja już popaść w kłopoty z uwsgi (nieważne nginx, który będzie . następnym krokiem
sudo nano /etc/uwsgi/apps-available/li.xml

sudo ln -s /etc/uwsgi/apps-available/li.xml /etc/uwsgi/apps-enabled/li.xml
Jednakże jeśli uruchomię go uzyskać:

więc mogę operacja odłączenia nie jest dozwolona, a adres powiązania jest już w użyciu (obok błędu python_plugin, którego również nie mam pojęcia, jak to rozwiązać!). Jeśli działam jako sudo, wygląda na to, że działa poprawnie ->

Czy ktoś może mi pomóc? Jak www-data jest w grupie www-data i prowadzi go, próbowałem kilka rzeczy:
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
Ale to naprawdę nie pomogło. Próbowałem też portu TCP zamiast unix/run/uwsgi/app/port, które nie miało żadnej różnicy ... To doprowadza mnie do szału :(Mam nadzieję, że ktoś ma pojęcie o tym, co się tutaj dzieje:
poważaniem,
wapiennym
edit: po serwerze restart nadal daje się erro ale inną:

Mały później komentarz: plugin python (który jest w każdym google przykład) nie wydaje się już konieczne w nowszych wersjach. W końcu to naprawdę działa łatwiej i po wyjęciu z pudełka, niż myślałem wcześniej! – Carst
Czy możesz odgadnąć bardziej szczegółowo, co pociąga za sobą poprawka? Jestem w tym samym scenariuszu, ale nie byłem w stanie odcyfrować czegoś odtwarzalnego w moim przypadku. – bearrito
Edytowałeś to, co zrobiłem! Ponadto: moje ograniczenia pamięci robotniczej są naprawdę, więc nie kopiujmy tego :) (ma to związek z ciężkim procesem analitycznym) – Carst
