DAViCal is an open-source calendar and contacts server that uses open protocols to store data. In this tutorial, we'll show you how to install DAViCal on Fedora CoreOS Latest.
Before you start this tutorial, you should have access to a Fedora CoreOS Latest instance with root privileges.
To install DAViCal, we need to install some required packages. Run the following command to install the required packages:
$ sudo dnf install -y postgresql-server httpd php php-pgsql php-mbstring php-gd
After the installation is complete, start the PostgreSQL server and enable it to start at boot:
$ sudo systemctl enable postgresql
$ sudo systemctl start postgresql
Now that we have installed PostgreSQL, we need to create a new database and a database user for DAViCal to use. To create a new database and a user, run the following command:
$ sudo su - postgres
$ psql
postgres=# CREATE USER davical WITH PASSWORD 'davicalpassword';
postgres=# CREATE DATABASE davical OWNER davical ENCODING 'UTF8';
postgres=# \q
$ exit
Next, we need to download DAViCal's source code and extract it. Run the following commands to download and extract the source code:
$ cd /tmp/
$ wget https://gitlab.com/davical-project/davical/-/archive/1.1.10/davical-1.1.10.tar.gz
$ tar -xzf davical-1.1.10.tar.gz
$ sudo mv davical-1.1.10 /var/www/html/davical
DAViCal comes with a configuration file named config.php.example. You need to copy this file to config.php and configure it according to your needs. Run the following commands to copy and configure the config.php file:
$ cd /var/www/html/davical/config/
$ cp config.php.example config.php
$ sudo nano config.php
Update the following parameters in the config.php file:
$c->pg_connect = 'host=localhost port=5432 dbname=davical user=davical password=davicalpassword options=\'--client-min-messages=warning\''; // Update according to PostgreSQL configuration
$c->server_name = 'https://yourdomain.com/davical/'; // Replace 'yourdomain.com' with your domain name
$c->server_admin = 'admin@yourdomain.com'; // Replace 'yourdomain.com' with your domain name
$c->admin_email = 'admin@yourdomain.com'; // Replace 'yourdomain.com' with your domain name
Save and exit the file.
Next, we need to set the correct file permissions on the DAViCal installation directory. Run the following command to set the correct file permissions:
$ sudo chown -R apache:apache /var/www/html/davical
DAViCal requires mod_rewrite to be enabled in Apache. Run the following command to enable mod_rewrite:
$ sudo a2enmod rewrite
Next, create a new virtual host configuration file for DAViCal. Run the following command to create the file:
$ sudo nano /etc/httpd/conf.d/davical.conf
Add the following configuration to the file:
<VirtualHost *:80>
ServerName yourdomain.com # Replace 'yourdomain.com' with your domain name
ServerAdmin admin@yourdomain.com # Replace 'yourdomain.com' with your domain name
DocumentRoot /var/www/html/davical/
RewriteEngine On
RewriteRule ^/principals /caldav.php/principals/ [PT]
RewriteRule ^/calendars/(.*) /caldav.php/calendars/$1 [PT]
RewriteRule ^/addressbooks/(.*) /carddav.php/addressbooks/$1 [PT]
<Directory /var/www/html/davical>
Options FollowSymLinks
AllowOverride All
Require all granted
</Directory>
</VirtualHost>
Save and exit the file.
Finally, restart Apache to apply the changes:
$ sudo systemctl restart httpd
Now that you have completed the installation, you can access DAViCal by navigating to http://yourdomain.com/davical/ using your web browser.
In this tutorial, you learned how to install DAViCal on Fedora CoreOS Latest. You also learned how to create a database, download and install DAViCal, set file permissions, configure Apache, and access DAViCal.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
