  Before you install DokuWiki on Ubuntu 22.04, you need to have the meet the prerequisites below.

Prerequisites

• Stable internet for downloading required packages
• Root privileges for installation
• A web server
• PHP

Install PHP

• Update system packages

sudo apt update && sudo apt upgrade -y

• Ubuntu 22.04 has PHP 8 in its repository but DokuWiki is well supported. Keep in mind that PHP 5.6 is the minimum supported version. Do some tweaks to install PHP 7.4

sudo add-apt-repository ppa:ondrej/php --yes &> /dev/null

sed -i 's/jammy/focal/' /etc/apt/sources.list.d/ondrej-ubuntu-php-jammy.list

sudo apt update

• For some reason Ubuntu 22.04 seems to be having broken packages. So ensure that libssl is installed. You may need to run apt update after this too.

wget http://archive.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.0g-2ubuntu4_amd64.deb

sudo dpkg -i libssl1.1_1.1.0g-2ubuntu4_amd64.deb

• Now install PHP 7.4 and required modules

sudo apt install php7.4 php7.4-gd php7.4-xml php7.4-json libapache2-mod-php7.4 -y

Install Apache Web Server

• Installation of PHP installs Apache2 server automatically. Confirm is Apach2 was installed. If a path is printed, it is installed, otherwise, it is not.

which apache2

• If it is not installed, install using the command:

sudo apt install apache2 -y

• Start and enable apache2 server on system start

sudo systemctl enable --now apache2

Allow HTTP access through firewall.

Ubuntu 22.04 has UFW as the firewall although it is not enabled by default. In case yours is running, you need to allow HTTP traffic through port 80.

sudo ufw allow Apache

            </IfModule>
            <IfModule !mod_authz_core.c>
                Order allow,deny
                Deny from all
            </IfModule>
