This is a complete Ubuntu Linux based web server for Website, PHP, SSL, TLS, Database and Email hosting purpose.
Built with the below components for good performance. Also, I tried to make it as secure as possible.

DISCLAIMER: I’m making this guide just for my own purpose and needs. But, If it meets your requirements,
please feel free to use those commands below. Remember, I’m not liable if any bad thing happens to your server.
My recommendation is to you that use this on a testing server before using it on a production server.
Just kidding; do whatever you like, at your own risk.

Please contact me: If you need Linux server maintenance and installation help.

### PCSNET info: You can now make multiple php version apps so old apps will be no problem to run!!! PS Best and secure is newer version of php8+, but many good apps dont run on newer version of php so use for them for example php5.6 or php7.0 Extention module apache fcgi, run your CMS in newest phpversion!
# # # # # # # # # # # # # # # # # # # # # #
## Check Avaliable PHP7.2 Extensions / Modules [OPTIONAL] sudo apt-cache search php7.2
sudo apt-cache search php7.4
# # # # # # # # # # # # # # # # # # # # # #

## Let’s Configure PHP7.2-FPM with Apache2
sudo a2enmod actions fcgid alias proxy_fcgi
sudo a2enconf php5.6-fpm php7.0-fpm php7.1-fpm php7.2-fpm php7.3-fpm
sudo a2enconf php7.4-fpm php8.2-fpm php8.1-fpm
sudo a2dismod mpm_prefork

## Below Commands is only for just to make sure that php7.2 is disables. May show errors that php7.2 is not exist…
sudo a2dismod php7.2
sudo a2enmod mpm_event

sudo systemctl restart apache2.service
sudo systemctl restart php5.6-fpm.service
sudo systemctl restart php7.0-fpm.service

sudo systemctl restart php7.4-fpm.service

sudo systemctl restart php8.1-fpm.service
sudo systemctl restart php8.2-fpm.service
sudo systemctl restart php8.0-fpm.service

## Configure PHP.ini file
sudo nano /etc/php/7.2/fpm/php.ini

sudo nano /etc/php/7.4/fpm/php.ini

sudo nano /etc/php/8.0/fpm/php.ini
sudo nano /etc/php/8.1/fpm/php.ini
sudo nano /etc/php/8.2/fpm/php.ini

# # # # # # # # # # # # # # # # # # # # # #
## Make the changes on the following lines below in the file and save…
cgi.fix_pathinfo=0
file_uploads = On
allow_url_fopen = On
date.timezone = Europe/Ljubljana
upload_tmp_dir = /var/tmp
post_max_size = 4096M
upload_max_filesize = 4096M
max_execution_time = 5000
max_input_time = 5000
memory_limit = 1024M
max_input_vars = 5000
# # # # # # # # # # # # # # # # # # # # # #

## Check installed php extensions
php -m

## Lets restart the service
sudo systemctl restart php7.2-fpm.service

sudo systemctl restart php7.4-fpm.service

sudo systemctl restart php8.0-fpm.service
sudo systemctl restart php8.1-fpm.service
sudo systemctl restart php8.2-fpm.service

 

03. HTTP/2 [OPTIONAL] ———————-

## Prerequisites
### Enable HTTPS on your server. All major browsers allow using of HTTP/2 only over HTTPS.
### TLS protocol version >= 1.2 with modern cipher suites is required.
### Ensure that you are running Apache 2.4.17 or above because HTTP/2 is supported from this version and upwards.
### If you run PHP in Apache via mod_php, you need to switch to FPM. That is not a bad thing. FPM is newer and faster.

Switching Apache’s PHP Module from MPM Prefork to Event
sudo apt-get install php7.2-fpm (not required if already installed)

sudo a2enmod proxy_fcgi

sudo a2enconf php7.4-fpm

sudo a2enconf php8.0-fpm
sudo a2enconf php8.1-fpm
sudo a2enconf php8.2-fpm
sudo a2dismod php7.2 (not required if not installed)
sudo a2dismod mpm_prefork
sudo a2enmod mpm_event
sudo systemctl restart apache2.service

## Lets enable the module mod_http2
sudo a2enmod http2
sudo systemctl restart apache2.service
sudo systemctl restart php7.4-fpm.service

sudo systemctl restart php8.0-fpm.service
sudo systemctl restart php8.1-fpm.service
sudo systemctl restart php8.2-fpm.service

## Enable the HTTP/2 protocol by adding the following to /etc/apache2/apache2.conf:
Protocols h2 http/1.1

sudo nano /etc/apache2/sites-available/example.com.conf
## Examples of adding apache2.conf file Protocols h2 http/1.1
# # # # # # # # # # # # # # # # # # # # # #
## Don not forget to put the below code inside the both SSL and HTTP conf for the domain
<VirtualHost *:443>
Protocols h2 http/1.1
...
...
...
</VirtualHost>
# # # # # # # # # # # # # # # # # # # # # #

## Lets restart few services
sudo systemctl restart apache2.service
sudo systemctl restart php7.2-fpm.service

## Verify that HTTP/2 is Working from here: https://tools.keycdn.com/http2-test

04. MariaDB
——————-

## Lets Install MariaDB Database Server
sudo apt-get install mariadb-server mariadb-client -y

# # # # # # # # # # # # # # # # # # # # # #
## Commands below can be used to stop, start and enable MariaDB service
sudo systemctl stop mariadb.service
sudo systemctl start mariadb.service
sudo systemctl enable mariadb.service
# # # # # # # # # # # # # # # # # # # # # #

## Secure MariaDB server
sudo mysql_secure_installation

# # # # # # # # # # # # # # # # # # # # # #
## Answer the questions below by following the guide.
Enter current password for root (enter for none): Just press the Enter
Set root password? [Y/n]: Y
New password: Enter password
Re-enter new password: Repeat password
Remove anonymous users? [Y/n]: Y
Disallow root login remotely? [Y/n]: Y
Remove test database and access to it? [Y/n]: Y
Reload privilege tables now? [Y/n]: Y
# # # # # # # # # # # # # # # # # # # # # #

## Let’s restart MariaDB server
sudo systemctl restart mariadb.service

05. phpMyAdmin [OPTIONAL] —————————

## Lets Install phpMyAdmin
sudo apt install phpmyadmin -y

# # # # # # # # # # # # # # # # # # # # # #
## When prompted to choose “Configuring phpmyadmin”
Web server to reconfigure automatically: select apache2 and continue. Configure database for phpmyadmin with dbconfig-common: Yes
Create a password for phpMyAdmin: Please provide a password for phpmyadmin to register with the database…
# # # # # # # # # # # # # # # # # # # # # #

## Lets restart
sudo systemctl restart apache2.service

## Now browse yourdomain.com/phpmyadmin and try to use (root) user login and password.
## Can’t login there? Because, (root) user login is not permitted! Lets fix it below…
sudo mysql -u root
use mysql;
update user set plugin='' where User='root';
flush privileges;
exit
sudo systemctl restart mariadb.service

06. LetsEncrypt [OPTIONAL] —————————

## Let’s make sure that the apache2 domain conf is avaliable
sudo nano /etc/apache2/sites-available/example.com.conf
sudo ln -s /etc/apache2/sites-available/example.com.conf /etc/apache2/sites-enabled/

# # # # # # # # # # # # # # # # # # # # # #
<VirtualHost *:80>
...
...
ServerName example.com
ServerAlias www.example.com
...
...
<VirtualHost>
# # # # # # # # # # # # # # # # # # # # # #

## Let’s Install Let’s Encrypt Apache Client
sudo apt-get install python3-certbot-apache -y

## Please repleace the below example.com text with your own domain name.
sudo certbot --apache --agree-tos --email admin@example.com --redirect --hsts -d example.com -d www.example.com

# # # # # # # # # # # # # # # # # # # # # #
## The commands options above are explained below:
### –apache: Use the Apache2 Let’s Encrypt installer
### –agree-tos: Agree to Let’s Encrypt terms of service
### –redirect: Adds 301 redirect.
### –email: Contact email address.
### –hsts: Adds the Strict-Transport-Security header to every HTTP response.
### – d flag is followed by domains you want to secure.
# # # # # # # # # # # # # # # # # # # # # #

## Now, the SSL client should install the cert and configure your website to redirect all traffic over HTTPS.
## A new configuration file for the domain should also be created named /etc/apache2/sites-available/example.com-le-ssl.conf.

## The below highlighted code block should be added to your website configuration file automatically by Let’s Encrypt certbot.
## Your site should be ready to be used over HTTPS.

# # # # # # # # # # # # # # # # # # # # # #
<VirtualHost *:80>
...
...
ServerName example.com
ServerAlias www.example.com
...
...
RewriteEngine on
RewriteCond %{SERVER_NAME} =example.com [OR]
RewriteCond %{SERVER_NAME} =www.example.com
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
...
...
<VirtualHost>
# # # # # # # # # # # # # # # # # # # # # #

## Let’s add Let’s Encrypt certificate auto renewal process using crontab sudo crontab -e

## Add the line below and save
# # # # # # # # # # # # # # # # # # # # # #
# Lets Encrypt Monthly Domain Auto Renewal
0 1 * * * /usr/bin/certbot renew & > /dev/null
# # # # # # # # # # # # # # # # # # # # # #

## Manual Let’s Encrypt Renewal command is below
sudo certbot renew --dry-run

07. IonCube [OPTIONAL] ————————

## Create a php info file in html folder and use your IP to browse it.
