Installing DAViCal on Clear Linux Latest

DAViCal is an open-source calendar and address book server that is designed to be very easy to set up and use. In this tutorial, we will guide you through the process of installing DAViCal on Clear Linux Latest.

Prerequisites

Before you start, you need to have the following:

• A system running Clear Linux Latest
• A user with sudo privileges
• Internet connectivity
• A domain name or IP address that you want to use for your DAViCal server

Step 1: Install PostgreSQL and Apache web server

The first thing you need to do is to install the PostgreSQL database and the Apache web server using the following command:

sudo swupd bundle-add postgresql server-apache

Step 2: Install PHP and related modules

Next, we need to install PHP and related modules. We can install them using the following command:

sudo swupd bundle-add php-basic php-pdo php-pgsql php-xml php-mbstring php-pecl-imagick

Step 3: Download and install DAViCal

We can download the latest release of DAViCal from its official website. In this tutorial, we will download version 1.1.9 using the following command:

wget https://github.com/stephane-klein/davical/releases/download/v1.1.9/davical-1.1.9.tar.gz

Once downloaded, extract the tarball using the following command:

tar -xzvf davical-1.1.9.tar.gz

Next, move the extracted directory to the default Apache web root directory using the following command:

sudo mv davical-1.1.9 /var/www/html/

Step 4: Create a PostgreSQL database user and a database

Now we need to create a PostgreSQL database user and a database for DAViCal. We can accomplish this by running the following commands:

sudo su postgres
createuser --pwprompt dcalendar
createdb --owner=dcalendar davical
exit

Step 5: Set up the DAViCal configuration file

Next, we need to set up the DAViCal configuration file. We can start by copying the config.php.example file to config.php using the following command:

cd /var/www/html/davical-1.1.9/
cp config.php.example config.php

Next, we need to edit config.php using our preferred text editor, and make the following changes:

• Set $c->pg_connect[] to the connection string for your PostgreSQL database (example: pgsql:host=localhost;dbname=davical)
• Set $c->base_url to the domain name or IP address of your DAViCal server
• Set $c->admin_email to your email address
• Set $c->admin_name to your name

sudo nano config.php

Once you are done editing the configuration file, save and close it.

Step 6: Set up the DAViCal database

Next, we need to set up the DAViCal database using the following command:

sudo -u apache php bin/mkcal.php --db davical --user dcalendar --create

This command will create the necessary tables and indexes in the PostgreSQL database.

Step 7: Set up Apache

Finally, we need to set up Apache to serve the DAViCal application. We can do this by creating an Apache configuration file for DAViCal using the following command:

sudo nano /etc/httpd/conf.d/davical.conf

Then, paste the following contents

Alias /davical /var/www/html/davical-1.1.9/
Alias /caldav /var/www/html/davical-1.1.9/caldav.php
Alias /carddav /var/www/html/davical-1.1.9/carddav.php

<Directory /var/www/html/davical-1.1.9>
  <IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteRule ^index\.php$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /index.php [L]
  </IfModule>
  <IfModule mod_php5.c>
    php_admin_flag engine on
    php_admin_value open_basedir "/var/lib/php/:/var/www/html/davical-1.1.9/"
  </IfModule>
</Directory>

<Location /davical/system/export/>
  <Limit PUT>
    Require all denied
  </Limit>
  <Limit DELETE>
    Require all denied
  </Limit>
</Location>

<Location /carddav/>
  <Limit PUT>
    Require all denied
  </Limit>
  <Limit DELETE>
    Require all denied
  </Limit>
  <Limit TRACE>
    Require all denied
  </Limit>
</Location>

<Location /caldav/>
  <Limit PUT>
    Require all denied
  </Limit>
  <Limit DELETE>
    Require all denied
  </Limit>
  <Limit TRACE>
    Require all denied
  </Limit>
</Location>

Save and close the file.

Finally, restart Apache using the following command:

sudo systemctl restart httpd

Step 8: Access DAViCal

You can now access DAViCal by navigating to http://your-domain-or-ip-address/davical/ in your web browser. You will see the DAViCal welcome screen.
