How to Install Omeka on Arch Linux

In this tutorial, we will show you how to install Omeka on Arch Linux. Omeka is a free, open-source content management system that allows you to create and publish digital exhibits and collections.

Prerequisites

Before you start installing Omeka, you need to have the following:

• A running instance of Arch Linux
• A user account with sudo privileges

Step 1: Update your system

The first step is to update the system packages and repositories using the following command:

sudo pacman -Syu

Step 2: Install Apache and MySQL

Omeka requires a web server and a database server to run. We will install Apache as the web server and MySQL as the database server.

sudo pacman -S apache
sudo pacman -S mysql

Step 3: Install PHP

Omeka is written in PHP, so we need to install PHP and its extensions. You can install PHP and the required extensions by running the following command:

sudo pacman -S php php-apache php-gd php-mysql php-intl php-zip php-xml

Once the installation is complete, restart Apache to apply the changes.

sudo systemctl restart httpd

Step 4: Download Omeka

Next, we will download the latest version of Omeka from the official website using the following command:

wget http://omeka.org/files/omeka-2.7.1.zip

Extract the downloaded file using the following command:

unzip omeka-2.7.1.zip

Move the extracted directory to the Apache web root directory.

sudo mv omeka-2.7.1 /srv/http/omeka

Step 5: Configure MySQL

The next step is to create a MySQL database and user for Omeka. Log in to the MySQL shell using the following command:

sudo mysql -u root -p

Create a new database for Omeka using the following command:

CREATE DATABASE omeka_db;

Create a new user and grant permissions to the Omeka database using the following command:

GRANT ALL PRIVILEGES ON omeka_db.* TO 'omeka_user'@'localhost' IDENTIFIED BY 'password';

Replace the "omeka_user" and "password" with your desired values.

Exit the MySQL shell.

exit

Step 6: Configure Apache

Create a new virtual host configuration file for Omeka using the following command:

sudo nano /etc/httpd/conf/extra/omeka.conf

Add the following configuration to the file and save it.

<VirtualHost *:80>

    ServerAdmin webmaster@localhost
    DocumentRoot "/srv/http/omeka"
    ServerName omeka.example.com

    ErrorLog "/var/log/httpd/omeka.error_log"
    CustomLog "/var/log/httpd/omeka.access_log" common

    <Directory "/srv/http/omeka">
        Require all granted
        AllowOverride All
    </Directory>

</VirtualHost>

Replace "omeka.example.com" with your domain name.

Enable the newly created virtual host configuration using the following command:

sudo a2ensite omeka.conf
sudo systemctl reload httpd

Step 7: Install Omeka

Open your web browser and go to the following URL:

http://omeka.example.com/install/install.php

Follow the on-screen instructions to complete the installation. You will be prompted to enter the MySQL database credentials that you configured in Step 5.

Congratulations! You have successfully installed Omeka on Arch Linux.
