Wagtail deployment on Centos7

Question

I could really use some help here. I am in the process of setting up a test deployment of wagtail on a CentOS7 box and it seems as though the wsgi daemon is not getting access to the necessary python modules. I have checked permissions on all of the directories in the virtual environment and made sure that the owner was apache as well as the group owner was apache (recursively). SELinux is also in permissive mode while I'm trying to figure this out. It's a fresh install of wagtail, no modifications have been made after running the start command from wagtail.

My virtual host config file is as follows:

<VirtualHost *:80>
ServerName <server.name>
ServerAdmin <server.admin>
Alias /static /var/www/<virtual.env>/<project.name>/static
<Directory /var/www/<virtual.env>/<project.name>/static>
    Require all granted
</Directory>
<Directory /var/www/<virtual.env>/<project.name>/wsgi.py>
    <Files wsgi.py>
        Require all granted
    </Files>
</Directory>
WSGIDaemonProcess <project> python-path=/var/www/<virtual.env>/<project.name>/<project.name>:/var/www/<virtual.env/lib/python3.4/site-packages
WSGIProcessGroup <project>
WSGIScriptAlias / /var/www/<project.env>/<project.name>/<project.name>/wsgi.py

ErrorLog /var/log/httpd/<project.name>_error.log
CustomLog /var/log/httpd/<project.name>_access.log combined

My project_error.log file contains the following:

Huge thanks in advance.

Answer 1

Two things I noticed. <Directory /var/www/<virtual.env>/<project.name>/wsgi.py> should point to the directory <Directory /var/www/<virtual.env>/<project.name>/ , not the file itself. Also, mod_wsgi needs to be compiled against the same version of Python you developed against, as @gasman mentioned.

If you want to upgrade to Python 3.5 and install mod_wsgi from the IUS repository:

sudo yum install https://centos7.iuscommunity.org/ius-release.rpm
sudo yum install python35u python35u-pip python35u-devel python35u-mod_wsgi

Good luck!
