Tutorial: How to Install Horde on Fedora CoreOS Latest

Horde is a webmail and collaboration suite that offers email, contact management, calendaring, tasks, notes, and more. This tutorial will guide you through the process of installing Horde on Fedora CoreOS, the latest version of the container-focused operating system.

Requirements

Before you start, make sure you have the following:

• A server running Fedora CoreOS
• Sudo access or root user privileges
• A web server (Apache or Nginx) installed and running on the same server as Fedora CoreOS
• Basic knowledge of Linux command line interface

Step 1: Install Required Packages

First, update the system package manager by running the following command:

sudo dnf update

Then, install the required packages for Horde using the following command:

sudo dnf install -y php php-pear php-mbstring php-xml php-pgsql php-ldap php-imap php-gd

Step 2: Download and Unpack Horde

Download the latest version of Horde from the official website at https://www.horde.org/ and save the package to a temporary location on your server.

Then, unpack the package to the web server root directory (/var/www/html) using the following command:

sudo tar -zxvf horde-5.2.22.tgz -C /var/www/html

Replace the "horde-5.2.22.tgz" with the name of the downloaded package file.

Step 3: Configure Horde

Create a new configuration file for Horde by copying the example file using the following command:

sudo cp /var/www/html/horde/config/conf.php.dist /var/www/html/horde/config/conf.php

Then, edit the configuration file using a text editor:

sudo nano /var/www/html/horde/config/conf.php

In the configuration file, set the following values:

• $conf['sql']['username'] - The username for your PostgreSQL database server.
• $conf['sql']['password'] - The password for your PostgreSQL database server.
• $conf['sql']['database'] - The name of the PostgreSQL database where Horde will store its data.
• $conf['sql']['phptype'] - The type of database, usually pgsql for PostgreSQL.

Save and close the file.

Step 4: Configure PostgreSQL

Create a new database for Horde using the following command:

sudo su - postgres -c "createdb horde"

Then, create a new user with a password using the following command:

sudo su - postgres -c "createuser -P horde"

Follow the prompts to set a password for the user.

Grant the new user permissions to the Horde database using the following command:

sudo su - postgres -c "psql -c 'grant all on database horde to horde;'

Step 5: Verify and Test

Restart your web server to apply the changes by running the following command:

sudo systemctl restart httpd

Now access the Horde web interface by entering your server's IP address or domain name in your browser followed by "/horde".

For example:

http://server_ip_address/horde

You should see the Horde login page.

Enter the username and password you created earlier in Step 4 to log in and start using Horde.

Congratulations! You have successfully installed Horde on Fedora CoreOS Latest.
