How to Install Horde on macOS

Horde is a free, open-source web-based groupware application. It provides a suite of tools that includes email, calendar, task-list, address book, and more.

In this tutorial, we will learn how to install Horde on macOS.

Prerequisites

Before installing Horde, you need to have the following installed on your macOS:

Apache web server
PHP 7.2 or higher
MySQL/MariaDB or PostgreSQL database server

Installation Steps

Download the latest version of Horde from https://www.horde.org/apps/horde/download.
Extract the downloaded archive to a directory on your macOS.
Open Terminal and navigate to the directory where you extracted Horde.
Run the following command to install the required dependencies:
```
composer install
```
Configure Apache web server to serve Horde.
- Open the Apache httpd.conf configuration file using your favorite text editor.
```
sudo nano /etc/apache2/httpd.conf
```
- Add the following lines at the end of the file.
```
Alias /horde "/path/to/horde/"
<Directory "/path/to/horde/">
    AllowOverride All
    Options FollowSymLinks MultiViews
    Require all granted
</Directory>
```
  Replace /path/to/horde/ with the actual path to the directory where you extracted Horde.
- Save and close the httpd.conf file.
Start Apache web server.
```
sudo apachectl start
```
Create a new database and user for Horde in your MySQL/MariaDB or PostgreSQL database server.
- Open the MySQL/MariaDB or PostgreSQL command-line interface.
- Create a new database.
```
CREATE DATABASE horde CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
```
- Create a new user and grant it full access to the database.
```
CREATE USER 'hordeuser'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON horde.* TO 'hordeuser'@'localhost';
```
  Replace hordeuser and password with your preferred username and password.
Configure Horde.
- Rename the conf.php.dist file to conf.php.
```
mv conf.php.dist conf.php
```
- Open the conf.php file using your favorite text editor.
- Change the following lines according to your MySQL/MariaDB or PostgreSQL database server configuration.
```
$conf['sql']['phptype'] = 'mysql';
$conf['sql']['username'] = 'hordeuser';
$conf['sql']['password'] = 'password';
$conf['sql']['protocol'] = 'tcp';
$conf['sql']['hostspec'] = 'localhost';
$conf['sql']['port'] = 3306;
$conf['sql']['database'] = 'horde';
```
  If you are using PostgreSQL, replace mysql with pgsql, and change the port number accordingly.
- Save and close the conf.php file.
Open a web browser and go to http://localhost/horde/. You should see the Horde login page.
Log in with the default username admin and the password pass.
Follow the on-screen instructions to set up Horde.

Congratulations! You have successfully installed Horde on your macOS.
