DAViCal is an open-source CalDAV and CardDAV server that allows you to sync your calendar and contact information across multiple devices.
In this tutorial, we will learn how to install DAViCal on Alpine Linux Latest. We will be using the Alpine Linux package manager to install DAViCal.
Before we start with the installation process, make sure that you have the following prerequisites:
The first step is to update the system to the latest packages. To do this, run the following command:
sudo apk update && sudo apk upgrade
DAViCal has some dependencies that need to be installed before installing DAViCal. We need to install Apache, PostgreSQL, and PHP.
Run the following command to install these dependencies:
sudo apk add apache2 postgresql postgresql-client php7 php7-fpm php7-pgsql php7-curl php7-mbstring php7-xml php7-zip
Once the dependencies are installed, we can proceed to install DAViCal.
Run the following command to download and install the DAViCal package:
sudo apk add davical
Once the installation is complete, DAViCal is installed and ready to use.
DAViCal uses Apache as its web server. We need to configure Apache to use DAViCal.
Run the following command to enable Apache modules and to configure the virtual host file for DAViCal:
sudo sh -c "cat <<EOF > /etc/apache2/conf.d/davical.conf
LoadModule dav_module /usr/lib/apache2/mod_dav.so
LoadModule dav_fs_module /usr/lib/apache2/mod_dav_fs.so
LoadModule davical_module /usr/lib/apache2/mod_davical.so
LoadModule auth_digest_module /usr/lib/apache2/mod_auth_digest.so
LoadModule rewrite_module /usr/lib/apache2/mod_rewrite.so
<VirtualHost *:80>
ServerName <your-server-name>
DocumentRoot /usr/share/davical/htdocs
DirectoryIndex index.php
## Change this to your timezone
SetEnv TZ Europe/London
## This is the path to the database configuration file.
## You should not need to change this unless you move things around
SetEnv DAVICAL_CONFIG /etc/davical/config.php
## Enable CalDAV/CardDAV and WebDAV access
<Directory /usr/share/davical/htdocs/>
Dav On
AllowOverride None
AuthType Digest
AuthName "DAViCal"
AuthDigestDomain /usr/share/davical/htdocs/
AuthDigestProvider file

Require valid-user
</Directory>

CustomLog /var/log/apache2/davical_access.log combined
</VirtualHost>
EOF"
Be sure to replace <your-server-name> with the domain name or IP address of your server.
DAViCal uses PostgreSQL as its database management system. We need to create a new PostgreSQL user and database for DAViCal.
Run the following commands to create a new PostgreSQL user and database:
sudo -u postgres createuser davical_appuser
sudo -u postgres createdb -O davical_appuser davical_db
DAViCal needs to be configured to use PostgreSQL as its database management system.
Run the following command to create the DAViCal configuration file:
sudo cp /etc/davical/config.php.example /etc/davical/config.php
Then, edit the /etc/davical/config.php file:
sudo nano /etc/davical/config.php
Change the following lines according to your setup:
$config['server']['type'] = 'pgsql';
$config['server']['hostname'] = 'localhost';
$config['calendar']['system_timezone'] = 'GMT';
$config['database']['name'] = 'davical_db';
$config['database']['user'] = 'davical_appuser';
$config['database']['password'] = '<your-password>';
Note that <your-password> should be replaced with the password you set for the davical_appuser PostgreSQL user.
To start the services, run the following commands:
sudo rc-service apache2 start
sudo rc-service postgresql start
sudo rc-update add apache2
sudo rc-update add postgresql
You can now access DAViCal by navigating to http://<your-server-ip>/caldav.php.
It will prompt you for a username and password, which you can create by running the following command:
sudo htdigest -c /etc/apache2/digest DAViCal <username>
Be sure to replace <username> with your desired username.
Congratulations! You have successfully installed DAViCal on Alpine Linux Latest.
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!
