This tutorial is for users of Debian GNU/Linux using the LAMP stack, wanting TLS encryption, multiple self-hosted websites, feature rich content management, etc., without sacrificing ownership or security. This tutorial will cover:

  • Establish LAMP stack
  • Virtual hosts for more than one website
  • TLS - Creation of self-signed SSL
  • TLS - Let's Encrypt with Certbot
  • MySQL survival commands
  • Installation of Joomla, Wordpress, Dokuwiki, Cacti
  • Installation and configuration of local sftp server
  • Directory permissions
  • firewall rules with ufw
  • symbolic links for External Drive outside of root of webserver (risky)

There is probably a bit more … but this will get us started. With the exception of Cacti, these are skills I learned on BSD / macOS and then migrated to Debian GNU/Linux which runs them better, has better implementations of the LAMP stack, more feature control, and most importantly is #freesoftware.

Installing apache, setting up two ore more websites. If you are interested in setting up a website outside of /var/www/, say for example, /home/server, then please see the addenda at the bottom covering non-standard web root directories. There is nothing wrong with this approach, but there are some simple precautions. For now, proceed with the examples below which guide you through creating two virtual hosts, but this can be scaled to as many as you like: 

sudo apt install apache2 
sudo mkdir -p /var/www/site1.com/public_html
sudo mkdir -p /var/www/site2.com/public_html
sudo chown -R $USER:$USER /var/www/site1.com/public_html 
sudo chown -R $USER:$USER /var/www/site2.com/public_html
sudo chmod -R 755 /var/www
nano /var/www/site1.com/public_html/index.html

<html>
  <head>
    <title>site1</title>
  </head>
  <body>
    <h1>site1</h1>
  </body>
</html>

nano /var/www/site2.com/public_html/index.html

<html>
  <head>
    <title>site2</title>
  </head>
  <body>
    <h1>site2</h1>
  </body>
</html>

sudo cp /etc/apache2/sites-available/000-default.conf /etc/apache2/sites-available/site1.com.conf
sudo cp /etc/apache2/sites-available/000-default.conf /etc/apache2/sites-available/site2.com.conf

sudo nano /etc/apache2/sites-available/site1.com.conf

<VirtualHost *:80>
      ServerAdmin name@site1.com
      ServerName site1.com
      ServerAlias www.site1.com
      DocumentRoot /var/www/site1.com/public_html
      ErrorLog ${APACHE_LOG_DIR}/error.log
      CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

sudo nano /etc/apache2/sites-available/site2.com.conf

<VirtualHost *:80>
      ServerAdmin name@site2.com
      ServerName site2.com
      ServerAlias www.site2.com
      DocumentRoot /var/www/site2.com/public_html
      ErrorLog ${APACHE_LOG_DIR}/error.log
      CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

sudo a2ensite site1.com.conf
sudo a2ensite site2.com.conf
sudo cp -r /var/www/html /root/
sudo rm -r /var/www/html
sudo a2dissite 000-default.conf

sudo nano /etc/hosts

127.0.0.1       localhost
127.0.1.1       host.domain.com  hostname
# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
#Virtual Hosts - NOT Optional - replace xxx etc., with external IP
xxx.xxx.xxx.xxx site1.com
xxx.xxx.xxx.xxx www.site1.com
xxx.xxx.xxx.xxx site2.com
xxx.xxx.xxx.xxx www.site2.com

sudo apache2ctl configtest 

sudo systemctl restart apache2.service

Visit site1.com and site2.com - debug, set up TLS - repeat this for additional sites, set up firewall w/ common exceptions. 

sudo ufw install
sudo ufw allow ssh
sudo ufw allow 22
sudo ufw allow 222
sudo ufw allow http
sudo ufw allow 80
sudo ufw allow https
sudo ufw allow 443
sudo ufw allow 'WWW Secure'
sudo ufw allow 'WWW Full'
sudo ufw allow 'WWW'
sudo ufw allow 1194/udp
sudo ufw allow 1194
sudo ufw allow git
sudo ufw allow openvpn
sudo ufw allow samba
sudo ufw allow nfs
sudo ufw allow vnc
sudo ufw allow 21
sudo ufw allow ftp
sudo ufw enable

Create self-signed TLS certificates, set up ssl.conf for each virtual host. 

sudo openssl req -x509 -nodes -days 365 -newkey rsa:4096 -keyout /etc/ssl/private/site1.key -out /etc/ssl/certs/site1.crt

Country Name (2 letter code) [AU]: <Country Initials>
State or Province Name (full name) [Some-State]: <State or Commonwealth, etc., Name>
Locality Name (eg, city) []: <City or Township, etc., Name> 
Organization Name (eg, company) [Internet Widgits Pty Ltd]: <Group or Entity, etc., Name>
Organizational Unit Name (eg, section) []: <Department or Branch, etc., Name>
Common Name (e.g. server FQDN or YOUR name) []: <site1 ip address>
Email Address []: person@site1.com

sudo openssl req -x509 -nodes -days 365 -newkey rsa:4096 -keyout /etc/ssl/private/site2.key -out /etc/ssl/certs/site2.crt

Country Name (2 letter code) [AU]: <Country Initials>
State or Province Name (full name) [Some-State]: <State or Commonwealth, etc., Name>
Locality Name (eg, city) []: <City or Township, etc., Name> 
Organization Name (eg, company) [Internet Widgits Pty Ltd]: <Group or Entity, etc., Name>
Organizational Unit Name (eg, section) []: <Department or Branch, etc., Name>
Common Name (e.g. server FQDN or YOUR name) []: <site1 ip address>
Email Address []: person@site1.com

Configure diffie-hellman key for all TLS enabled virtual hosts, configure ssl-params.conf for all TLS enabled virtual hosts. 

sudo openssl dhparam -out /etc/ssl/certs/dhparam.pem 4096
sudo cp /etc/apache2/conf-available/ssl-params.conf /root/
sudo nano /etc/apache2/conf-available/ssl-params.conf

Configure virtual hosts for TLS for each domain previously configured above. 

sudo cp /etc/apache2/sites-available/default-ssl.conf /root/default-ssl.conf.bak
sudo cp /etc/apache2/sites-available/default-ssl.conf /etc/apache2/sites-available/site1.com-ssl.conf.bak
sudo cp /etc/apache2/sites-available/default-ssl.conf /etc/apache2/sites-available/site2.com-ssl.conf.bak

Create TLS sites in sites-enabled: 

sudo nano /etc/apache2/sites-available/site1.com-ssl.conf

<IfModule mod_ssl.c>

              CustomLog ${APACHE_LOG_DIR}/access.log combined
              SSLEngine on
              SSLCertificateFile      /etc/ssl/certs/site1.crt

              <Directory /usr/lib/cgi-bin>
                              SSLOptions +StdEnvVars
              </Directory>
              BrowserMatch "MSIE [2-6]" \
                             nokeepalive ssl-unclean-shutdown \
                             downgrade-1.0 force-response-1.0
      </VirtualHost>
</IfModule>
sudo nano /etc/apache2/sites-available/site2.com-ssl.conf

  <IfModule mod_ssl.c>
      <VirtualHost _default_:443>
              ServerAdmin name@site2.com
              ServerName site2.com
              ServerAlias www.site2.com

              SSLCertificateFile      /etc/ssl/certs/site2.crt
              SSLCertificateKeyFile /etc/ssl/private/site2.key
              <FilesMatch "\.(cgi|shtml|phtml|php)$">
                              SSLOptions +StdEnvVars
              </FilesMatch>
              <Directory /usr/lib/cgi-bin>
                              SSLOptions +StdEnvVars

Redirect the original sites-enabled to default to TLS. 

sudo nano /etc/apache2/sites-available/site1.com.conf
      Redirect permanent "/" "https://site1.com/
sudo nano /etc/apache2/sites-available/site2.com.conf
      Redirect permanent "/" "https://site2.com/

Enable both TLS sites, check configuration: 

sudo a2enmod ssl
sudo a2enmod headers
sudo a2ensite site1.com-ssl.conf
sudo a2ensite site2.com-ssl.conf
sudo apache2ctl configtest

Ignore error below, or set global ServerName (not advised) to avoid: 

AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1. Set the 'ServerName' directive globally to suppress this message
Syntax OK
sudo systemctl restart apache2

Set up Let's Encrypt for free certificate authority on the SSL certs you just made. 

sudo apt install certbot letsencrypt python-certbot-apache
certbot --authenticator standalone --installer apache -d site1.com --pre-hook "systemctl stop apache2" --post-hook "systemctl start apache2"
certbot --authenticator standalone --installer apache -d site2.com --pre-hook "systemctl stop apache2" --post-hook "systemctl start apache2"
sudo systemctl restart apache2

Test them both, first clear cache and restart browser, set up cron job to update every week: 

https://www.ssllabs.com/ssltest/analyze.html?d=site1.com&latest
https://www.ssllabs.com/ssltest/analyze.html?d=site2.com&latest

sudo crontab -e
30 2 * * 1 /usr/bin/certbot renew >> /var/log/le-renew.log
sudo systemctl restart cron.service
sudo systemctl restart apache2

Manually check certificates by: 

sudo certbot renew

Might be a good idea now … to set up a self-hosted Word Press site … Check this tutorial: Self-Hosted Word Press
