Hello, friends. In this post, you will learn how to install Baikal on Ubuntu 22.04 and create your own Calendar server. Let’s go.

According to Baikal website

Baïkal is a lightweight CalDAV+CardDAV server. It offers an extensive web interface with easy management of users, address books and calendars. It is fast and simple to install and only needs a basic php capable server. The data can be stored in a MySQL or a SQLite database.

One of the great advantages it offers is that it is open source and being created with web technology, you can install it without problems in many web servers. In addition to this, it is designed so that customers can access from the mobile (Android, iOS) or from the web browser.

But it is also excellent because it allows full integration with Thunderbird, so many companies will see it with good eyes.

Create your own Calendar server with Baikal

Before proceeding with the installation of Baikal, you need to update the whole system. So log in with your root user and run.

sudo apt update
sudo apt upgrade

Then, proceed to install a LAMP server. Remember that Baikal requires PHP 7+ and a database manager like MariaDB.

To achieve it all in one command, run this

sudo apt install apache2 mariadb-server php8.1 libapache2-mod-php php8.1-intl php8.1-curl php8.1-curl php8.1-mbstring php8.1-gd php8.1-exif php8.1-cgi php8.1-xml php8.1-mysqlnd unzip

Next, make sure that ports 80 and 443 are open in the firewall

sudo ufw allow 80
sudo ufw allow 443

This is enough for now.

Preparing a database for Baikal

The goal of this post is to install Baikal on a sample environment. Of course, you can always improve the steps and increase the security. For example, you can check this post, where we detail more the installation of MariaDB on Ubuntu 22.04

Now create a new database for Baikal. Assign it the name you want.


Then the user, his password, and the permissions on the new database

GRANT ALL PRIVILEGES ON baikal.* TO 'user'@'localhost' IDENTIFIED BY 'pss';

Refresh permissions


And finally exit the console.


MariaDB is ready for Baikal.

Make Apache the owner of the folder and give it the correct permissions.

        Require all granted

    <IfModule mod_expires.c>
        ExpiresActive Off

  1. Thanks for this,
    A straightforward setup that works. I only wish I’d found it before I lost a couple of hours trying the composer route.
