+# Installing Apache2 and mod_wsgi on Ubuntu 18.04
+
+Prepare the system:
+```bash
+# Update the System
+sudo apt update && sudo apt upgrade -y
+
+# Install Apache, mod_wsgi, and python3-venv module
+sudo apt install apache2 libapache2-mod-wsgi-py3 python3-venv -y
+
+# Add User to www-data Group
+sudo usermod -aG $(whoami) www-data
+```
+
+For the group assignment to take effect you need to logout and back in.
+
+Prepare document root:
+```bash
+# Make Directory Structure in Root of:
+.
+└── api
+	└── webqueue2_api
+		├── __init__.py
+		└── webqueue2_api.wsgi
+
+# Create Python virtual environment
+cd /var/www/html && python3 -m venv venv
+```
+
+**__init__.py:** (Whatever the API code is)
+```python
+from flask import Flask
+app = Flask(__name__)
+@app.route("/")
+def hello():
+	return "Hello, Flask!"
+if __name__ == "__main__":
+	app.run()
+```
+
+**webqueue2_api.wsgi** (Code calling the Flask app)
+```python
+#!/usr/bin/python3
+import sys
+sys.path.insert(0,"/var/www/html/api")
+from webqueue2_api import app as application
+```
+Configure Apache2
+```bash
+# Add Apache configuration
+sudo nano /etc/apache2/sites-available/flasksite.conf
+```
+
+**flasksite.conf**
+```
+WSGIPythonHome /var/www/html/api/webqueue2_api/venv
+<VirtualHost *:80>
+	ServerAdmin webmaster@localhost
+	DocumentRoot /var/www/html
+
+	ErrorLog ${APACHE_LOG_DIR}/error.log
+	CustomLog ${APACHE_LOG_DIR}/access.log combined
+
+	WSGIScriptAlias /api /var/www/html/api/webqueue2_api/webqueue2_api.wsgi
+</VirtualHost>
+```
+
+```bash
+# Enable the new site
+sudo a2ensite flasksite.conf
+
+# Reload apache2
+sudo systemctl reload apache2
+```
