Django 2.1 deployment on centos 7 with apache, mod_wsgi, python3 venv

Question

I've stumbled with this seemingly most relevant deployment option because guides seem to either reference mod_wsgi with python2, or deployment on deb based systems where expected paths are different.
So I'm following these steps:

#repos for python3.6, wsgi for python3.6 yum install epel-release centos-release-scl #base packages yum install python36 python36-devel httpd httpd-devel rh-python36-mod_wsgi #python3.6 venv cd /var/www; python36 -m venv django-venv source django-venv/bin/activate pip3 install django #apache config to support wsgi edit /etc/httpd/conf/httpd.conf to include LoadModule wsgi_module modules/mod_wsgi.so 

apache config to serve django content located at /var/www/mysite

<VirtualHost *:80> ServerAdmin [email protected] ServerName mysite.com ServerAlias www.mysite.com WSGIDaemonProcess mysite python-home=/var/www/django-venv/ python-path=/var/www/django-venv/lib/python3.6/site-packages WSGIProcessGroup mysite WSGIScriptAlias / /var/www/mysite/mysite/wsgi.py Alias /static /var/www/mysite/static <Directory /var/www/mysite/mysite/static> Require all granted </Directory> <Directory /var/www/mysite/mysite> <Files wsgi.py> Require all granted </Files> </Directory> </VirtualHost> 

SEL changes:
chown apache:apache -R /var/www/mysite chown apache:apache -R /var/www/django-venv

httpd starts successfully but I keep getting the following in the error log:

Current thread 0x00007f5b5a486880 (most recent call first): [Fri Nov 23 14:29:02.019635 2018] [core:notice] [pid 4837] AH00052: child pid 5159 exit signal Aborted (6) Fatal Python error: Py_Initialize: Unable to get the locale encoding ModuleNotFoundError: No module named 'encodings' 

Could you guys confirm what am I missing in the steps so far for this setup?

I got everything to work. Here are the full steps:

yum install epel-release centos-release-scl yum install python36 python36-devel httpd httpd-devel rh-python36-mod_wsgi` 

Check if rh-python36-mod_wsgi places everything in correct dirs

rpm -ql rh-python36-mod_wsgi 

If found in:

/opt/rh/httpd24/root/etc/httpd/conf.modules.d/10-rh-python36-wsgi.conf /opt/rh/httpd24/root/usr/lib64/httpd/modules/mod_rh-python36-wsgi.so 

Move them to:

/etc/httpd/conf.modules.d/10-rh-python36-wsgi.conf /etc/httpd/modules/mod_rh-python36-wsgi.so 

Create python3 venv. if you're moving from somewhere, not creating in, check SEL to make sure apache can use it

cd /var/www python36 -m venv django-venv source /var/www/django-venv/activate 

Configure virtual host at /etc/httpd/conf.d/django.conf

<VirtualHost *:80> ServerName mysite.com ServerAlias www.mysite.com WSGIDaemonProcess mysite python-home=/var/www/django-venv python-path=/var/www/mysite WSGIProcessGroup mysite WSGIScriptAlias / /var/www/mysite/mysite/wsgi.py Alias /static /var/www/mysite/static <Directory /var/www/mysite/static> Require all granted </Directory> <Directory /var/www/mysite/mysite> <Files wsgi.py> Require all granted </Files> </Directory> </VirtualHost> 

If project is moved to /var/www, restore correct SEL labels:

restorecon -Rv /var/www 

Make project dir owned by apache:

chown -R apache:apache /var/www/mysite 

If SQLite is used, allow SEL to permit apache access to it (improvement needed):

semanage boolean -p http_unified on
