-===== PHP installation ===== +===== PHP Installation (Specified: PHP 8.4) ===== 
-Installing PHP's versions and libraries are pretty easy with the Ondrej Sury's personal package archive (PPA). I will install PHP 8.4 for this guide, but you can check which PHP version you want to install from the following page: [[https://launchpad.net/~ondrej/+archive/ubuntu/php|https://launchpad.net/~ondrej/+archive/ubuntu/php]]+The **Ondrej Sury PPA** is used for installing and managing PHP versions. We will target **PHP 8.4** as specified. You can check the available versions and their support status on the official PPA page: [[https://launchpad.net/~ondrej/+archive/ubuntu/php|ondrej/php PPA]]
  
 ==== Adding Repository ==== ==== Adding Repository ====
 +The PPA must be added to your system's sources list.
 <code bash> <code bash>
-sudo add-apt-repository ppa:ondrej/php+sudo add-apt-repository ppa:ondrej/php -y 
 +sudo apt update
 </code> </code>
  
-After adding the repository successfully, we can update the system.+==== Installing PHP and Required Modules ==== 
 + 
 +DokuWiki requires specific PHP modules (extensions). The following command installs PHP 8.4 alongside the necessary modules for DokuWiki's functionality (e.g., image manipulation, multi-byte string handling, XML parsing, and internationalization).
  
 <code bash> <code bash>
-sudo apt update+sudo apt install -y php8.4 php8.4-fpm php8.4-cli php8.4-gd php8.4-mbstring php8.4-xml php8.4-zip php8.4-intl php8.4-pdo php8.4-mysql

-==== Installing PHP ====+<WRAP center round info 60%> 
 +**Note:** We include **php-fpm** for use with high-performance web servers like **Nginx** or **Apache** via **mod_fcgid** or **mod_proxy_fcgi**. If you encounter issues, ensure `php8.4` is available in the PPA at the time of installation, as this version may be a development or future release.

 +===== MariaDB Server Installation ===== 
 +MariaDB is the recommended drop-in replacement for MySQL. 
 + 
 +==== Installation ====
 <code bash> <code bash>
-sudo apt install -y php8.4 php8.4-gd php8.4-mbstring php8.4-xml php8.4-zip php8.4-intl+sudo apt install mariadb-server -y 
 +sudo systemctl start mariadb 
 +sudo systemctl enable mariadb
 </code> </code>
  
-===== MySQL or MariaDB =====+==== Initial Security Setup ==== 
 +Then, secure the installation by running the following script. **Execute all steps carefully.**
 <code bash> <code bash>
-sudo apt install mariadb-server+sudo mysql_secure_installation
 </code> </code>
  
-Then we can start the installation by:+* **1- Enter current password for root (enter for none):** 
 +    * **Action:** Press **ENTER** (the root MariaDB user has no password by default after installation). 
 + 
 +* **2- Switch to unix_socket authentication [Y/n]:** 
 +    * **Action:** Type **n**. We will set a password instead. 
 + 
 +* **3- Change the root password? [Y/n]:** 
 +    * **Action:** Type **Y** and set a strong password. 
 +    * RESPONSE: 
 +        - New password: SET A STRONG PASS 
 +        - Re-enter new password: RE-ENTER PASS 
 + 
 +* **4- Remove anonymous users? [Y/n]:** 
 +    * **Action:** Type **Y**. Anonymous users are a security risk. 
 + 
 +* **5- Disallow root login remotely? [Y/n]:** 
 +    * **Action:** Type **Y**. **Highly Recommended** for security unless absolutely required. 
 + 
 +* **6 - Remove test database and access to it? [Y/n]:** 
 +    * **Action:** Type **Y**. 
 + 
 +* **7 - Reload privilege tables now? [Y/n]:** 
 +    * **Action:** Type **Y**. This applies the changes immediately.
  
 +==== MariaDB Service Status ====
 +When installed from the default repositories, MariaDB will start running automatically. To test the MariaDB's status, you can run the following command:
 <code bash> <code bash>
-sudo mysql_secure_installation+sudo systemctl status mariadb
 </code> </code>
  
-Installation script will ask some questions: +You should see a similar output as following one:

 +===== Composer Installation =====
 +Composer has an awesome description and installation guide on its webpage. You can use the following link: [[https://getcomposer.org/download/]] and see the section that "Command-line installation". I am just referencing the same code here:
 +
 +It is better to go your home directory first:
 +<code bash>
 +cd ~
 +</code>
 +
 +== 1. Download the terminal script ==
 +<code bash>
 +php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
 +</code>
 +
 +== 2. Check the hash file ==
 +<code bash>
 +php -r "if (hash_file('sha384', 'composer-setup.php') === 'c8b085408188070d5f52bcfe4ecfbee5f727afa458b2573b8eaaf77b3419b0bf2768dc67c86944da1544f06fa544fd47') { echo 'Installer verified'.PHP_EOL; } else { echo 'Installer corrupt'.PHP_EOL; unlink('composer-setup.php'); exit(1); }"
 +</code>
 +It should return the following message: **Installer verified**
 +== 3. Run the Script ==
 +<code bash>
 +php composer-setup.php
 +</code>
 +
 +It should return the following message:
 +
 +<code bash>
 +All settings correct for using Composer
 +Downloading...
 +
 +Composer (version 2.9.2) successfully installed to: /home/USER/composer.phar
 +Use it: php composer.phar
 +</code>
 +
 +
 +== 4. Delete (Unlink) the File ==
 +<code bash>
 +php -r "unlink('composer-setup.php');"
 +</code>
 +
 +== 5. Add it to the PATH ==
 +Then you can add the composer into your PATH to access the composer with just running `composer` command from any directory:
 +<code bash>
 +sudo mv composer.phar /usr/local/bin/composer
 +</code>
 +
 +== 6. Test the Installation ==
 +<code bash>
 +composer --version
 +</code>
 +
 +You need to see something similar like:
 +<code bash>
 +Composer version 2.9.2 2025-11-19 21:57:25
 +PHP version 8.4.15 (/usr/bin/php8.4)
 +Run the "diagnose" command to get more detailed diagnostics output.
