Python3 + venv + wsgi implementation

Issue description

The mod_wsgi engine cannot find python modules / project files after configuration

Scripts

⚠️ The name of project folders, repository, IP address of the remote are variables and may differ from your implementation, pay special attention for not just copy and paste the commands

Install Apache engine

  1. Now install apache software as grader.
  sudo apt-get install apache2
  1. Enter public IP of the Amazon EC2 instance into browser to check whether Apache installed or not. If success, it displays the APACHE PAGE. Step 3. Now again install library functions of apache using the command
sudo apt-get install libapache2-mod-wsgi-py3

Step 3. Enable the mod_wsgi using the command:

sudo a2enmod wsgi

Step 4. Install some libraries of python development:

sudo apt-get install libpq-dev python-dev

Installing the virtual environment

  1. From /var/www/catalog/catalog directory install pip:
sudo apt-get install python3-pip.
  1. Install the virtual environment:
sudo apt-get install python-virtualenv
  1. Create the virtual environment:
sudo virtualenv -p python3 venv3.
  1. Change the ownership to grader with:
sudo chown -R grader:grader venv3/.

Clone your project

cd /var/www/catalog
git clone https://github.com/youraccount/projectrepo

Create the .wsgi file (check content on screenshots)

touch catalog.wsgi

Install app dependecies

cd projectFolder
pip install requirements.txt //assuming that there is a requirements file, otherwise install manually every dependency

Configure and Enabling New Virtual Host

  1. Configure by typing the following command:
sudo nano /etc/apache2/sites-available/catalog.conf
  1. Add the following lines:
<VirtualHost *:80>
    ServerName YOUR_REMOTE_IP
    ServerAlias YOUR_REMOTE_NAME_SERVER (optional)
    ServerAdmin ubuntu@YOUR_REMOTE_IP
    WSGIDaemonProcess catalog python-path=/var/www/catalog:/var/www/catalog/catalog/venv3/lib/python3.6/site-packages
    WSGIProcessGroup catalog
    WSGIScriptAlias / /var/www/catalog/catalog.wsgi
    <Directory /var/www/catalog/catalog/>
        Order allow,deny
        Allow from all
    </Directory>
    Alias /static /var/www/catalog/catalog/static
    <Directory /var/www/catalog/catalog/static/>
        Order allow,deny
        Allow from all
    </Directory>
    ErrorLog ${APACHE_LOG_DIR}/error.log
    LogLevel warn
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
  1. Enable the virtual host by using the command:
sudo a2ensite catalog
  1. Type the following command for restarting the apache:
service apache2 reload
service apache2 restart
