Questions[uwsgi](ubuntu)

I'm working on this tutorial to setup uWSGI but I'm stuck by this command:

uwsgi --http :8080 --home /home/user/Env/firstsite --chdir /home/user/firstsite -w firstsite.wsgi

first of all, my actual directory path in /home/ubuntu/Es2al2/website, "website": is a project which I work on.

I have no idea what is that command does exactly also, I place my virtual environment into the project itself like so: /home/ubuntu/Es2al2/website/venv/ so, how can I show virtual environment for uWSGI, have I should place my venv like he does by outside the main project or may I place my own venv as I typed in my path?

Note:

"firstsite" is the project that tutorial has created and you can substitute by my real project "website" instead, as I explained.

I get the following error:

The error says I do not have a C compiler but gcc is installed.

Good day! I have an apache and wsgi application. Everything works fine, but I can’t configure Apache so that the Cyrillic alphabet is written to the journal in its normal form, and not \ xd0 \ xa1 \ xd0. The application works with strings normally, but if I give print(), nonsense is written to the log.

I tried all the options except the right one. Py 3.6 Ubumtu 18 Apache 2.4

I have installed "uwsgi" using pip method. But when I run uwsgi, I'm getting "Command 'uwsgi' not found, but can be installed with" error. If I again try to install using pip, I'm getting

Collecting uwsgi
Installing collected packages: uwsgi
Successfully installed uwsgi-2.0.18

which means it's already been installed.

What else am I missing out here. Thank you.

I am trying to deploy a django website on a Ubuntu 16.04 system using nginx but I am having issues.

ERRORS

Error I get from my nginx error.log file:

SET UP

• Using Python 3
• Ubuntu 16.04
• Using Virtualenvwrapper and virtualenv

Virtualenvwrapper set up

echo "export WORKON_HOME=~/Env" >> ~/.bashrc
echo "source /usr/local/bin/virtualenvwrapper.sh" >> ~/.bashrc

/etc/uwsgi/sites/contoursandcolors.ini:

[uwsgi]
project = contoursandcolors
uid = teddycrepineau
base = /home/%(uid)

chdir = %(base)/%(project)
home = %(base)/Env/%(project)
module = %(project).wsgi:application

master = true
processes = 2

socket = %(base)/%(project)/%(project).sock
chmod-socket = 664
vacuum = true

/etc/nginx/sites-available/contoursandcolor:

server {
        listen 80;
        server_name 173.255.210.63;

        location = /favicon.io { access_log off; log_not_found off; }

        location /static/ {
                root /home/teddycrepineau/contoursandcolors;
        }

        location / {
                include uwsgi_params;
                uwsgi_pass unix:/home/teddycrepineau/contoursandcolors/contoursandcolors.sock;
        }
}

WHAT I'VE TRIED

• Changed default python version from 2.7 to 3.5
• Change socket file location from project to run (get me a file not found error)
• I looked at quite a few StackExchange posts, but none have resolved my issue thus far

From what I read, my issue may be related to virtualenv location set up. Where should I go from here?

EDIT

I ended up using gunicorn (instead of uWSGI). It worked fine and was pretty easy to set up. Here is the link to the tutorial: https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-16-04
