Set up Apache¶

1. Install Apache + mod_wsgi¶

Command:

sudo apt-get update
sudo apt install apache2 libapache2-mod-wsgi-py3

2. Install SSL Certificates¶

Obtain SSL certificates to enable HTTPS from a Certificate Authority(CA) like Let’s Encrypt. See SSL Certificates of how to get SSL certificates from Let’s Encrypt.

See NO-IP Client of how to setup of a Linux dynamic update client to automatically updates the hostname to the correct IP address for the SSL certificates.

3. Enable SSL and WSGI¶

Apache needs the SSL and WSGI module enabled:
sudo a2enmod ssl
sudo a2enmod wsgi

4. Enable proxy modules¶

Enable necessary Apache proxy modules:
sudo a2enmod proxy proxy_http

5. Service for Apache Server¶

The service apache2 for the Apache Server has been automatically created in the directory /lib/systemd/system.

6. Configure Apache¶

Main configuration in /etc/apache2/apache2.conf:
sudo nano /etc/apache2/apache2.conf

7. Configure Apache Ports¶

Main configuration in /etc/apache2/apache2.conf:
sudo nano /etc/apache2/apache2.conf

8. Configure Virtual Hosts¶

Create separate configuration files for each virtual host in the directory /etc/apache2/sites-available/.

For example for dingx.gotdns.ch:

sudo nano /etc/apache2/sites-available/dingx.gotdns.ch.conf

Content:

<VirtualHost *:443>
    ServerName dingx.gotdns.ch
    ServerAlias dingx.gotdns.ch

    DocumentRoot /var/www/html

    SSLEngine on
    SSLCertificateFile /etc/letsencrypt/live/dingx.gotdns.ch/cert.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/dingx.gotdns.ch/privkey.pem
    SSLCertificateChainFile /etc/letsencrypt/live/dingx.gotdns.ch/chain.pem

    <Directory /var/www/html>
        Options FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>

</VirtualHost>

9. Enable virtual host¶

Enable the virtual host using the a2ensite command:
sudo a2ensite dingx.gotdns.ch.conf
A symbolic link will be created in /etc/apache2/sites-enabled to enable the virtual host.

10. Disable virtual host¶

Disable the virtual host configuration file using the a2dissite command:
sudo a2dissite dingx.gotdns.ch
The symbolic link in /etc/apache2/sites-enabled will be deleted.

11. Test the Apache configuration¶

sudo apache2ctl -t

12. Restart Apache¶

Restart Apache after making any changes to Apache’s configuration for the changes to take effect:
sudo systemctl daemon-reload
sudo systemctl restart apache2
