Before we get started, make sure that your system is up to date by running the following command in the terminal:

Step 1: Install Apache2 and PostgreSQL

We need to install Apache2 web server and PostgreSQL database to use DAViCal. Run the following command to install them:

sudo apt install apache2 postgresql -y

Step 2: Install DAViCal

To install DAViCal, we need to add its repository to our system:

sudo echo "deb https://debian.davical.org/ buster-davical main" > /etc/apt/sources.list.d/davical.list

Next, download the repository key and add it to your trusted keys:

wget -O - https://debian.davical.org/debian.davical.org.gpg | sudo apt-key add -

Now run the update command:

sudo apt update

Once all the packages are updated, run the installation command for DAViCal:

Step 3: PostgreSQL Setup

We need to create a PostgreSQL database for DAViCal. Run the following command to enter into the PostgreSQL shell:

sudo -u postgres psql

Create a new user with a password:

create user davical_app_user with password 'password';

Next, create a database for DAViCal:

create database davical_db owner davical_app_user encoding 'UTF-8' template template0;

Exit from the PostgreSQL shell by running:

\q

Step 4: DAViCal Configuration

Now we need to configure DAViCal. Open the following configuration file in your favorite text editor:

$sysabbr = "DAViCal";
$admin_email = "[email protected]";
$admin_password = "password";
$db_dsn = "pgsql:host=localhost;port=5432;dbname=davical_db";
$db_username = "davical_app_user";
$db_password = "password";

Save the file and exit.

Step 5: Apache2 Configuration

We need to configure Apache2 to serve DAViCal. Open the Apache2 default configuration file in your text editor:

sudo nano /etc/apache2/sites-available/000-default.conf

Add the following lines to the file:

Alias /davical /usr/share/davical/htdocs

<Location /davical>
  SetHandler php-fcgi
  Action php-fcgi /fcgi-bin/php-cgi.cgi
  AuthType Basic
