Omeka is an open-source web publishing platform that is designed to showcase cultural heritage materials, scholarly research, and digital exhibits. In this tutorial, we will walk you through the steps to install Omeka on the latest version of Fedora CoreOS.
Before we begin, make sure you have the following:
Omeka requires a web server to function properly. In this tutorial, we will use Apache as our webserver. To install Apache, run the following command:
sudo dnf install httpd
Once the installation is complete, start the Apache service and enable it to start at boot time:
sudo systemctl start httpd
sudo systemctl enable httpd
To check if Apache is running, open your web browser and enter your server's IP address. You should see the Apache default page.
Omeka is a PHP application, so we need to install PHP on our server. To install PHP and its dependencies, run the following command:
sudo dnf install php php-mysqlnd php-xml php-gd php-zip
Once the installation is complete, restart Apache to load the PHP module:
sudo systemctl restart httpd
To verify if PHP is installed correctly, create a PHP test file by entering the following command:
sudo nano /var/www/html/info.php
In the file, enter the following PHP code:
<?php
phpinfo();
Save the file and exit. Now open your web browser and enter http://your_server_ip/info.php. You should see a PHP information page.
Omeka uses a MySQL or MariaDB database to store its data. To install MariaDB, run the following command:
sudo dnf install mariadb-server
Once the installation is complete, start the MariaDB service and enable it to start at boot time:
sudo systemctl start mariadb
sudo systemctl enable mariadb
Next, secure your MariaDB installation by running the following command:
sudo mysql_secure_installation
Follow the prompts and answer the questions as per your requirements.
Now, we need to create a database and a user for Omeka. Log in to the MySQL/MariaDB shell with the following command:
sudo mysql
Enter the following commands to create a new MariaDB database, user, and grant permissions to the user:
CREATE DATABASE omeka_db;
GRANT ALL ON omeka_db.* TO 'omeka_user'@'localhost' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;
EXIT;
Make sure to replace omeka_user and password with your desired username and password.
Before installing Omeka, we need to download it from the official website. Run the following command to download the latest version of Omeka:
wget https://omeka.org/download/latest/omeka-2.7.1.zip
Unzip the downloaded file and move it to the Apache document root directory:
unzip omeka-2.7.1.zip
sudo mv omeka-2.7.1 /var/www/html/omeka
Next, set the correct ownership and permissions for the Omeka directory:
sudo chown -R apache:apache /var/www/html/omeka
sudo chmod -R 755 /var/www/html/omeka
We need to configure Omeka with the database details and other settings. Open the Omeka configuration file with the following command:
sudo nano /var/www/html/omeka/application/config/config.ini
Change the following lines as below:
database.host = "localhost"
database.username = "omeka_user"
database.password = "password"
database.dbname = "omeka_db"
Save the file and exit.
Now we need to configure Apache to serve Omeka from the document root directory. Open the Apache virtual host configuration file using the following command:
sudo nano /etc/httpd/conf.d/omeka.conf
Enter the following lines:
<VirtualHost *:80>
ServerName your_domain_name.com
ServerAlias www.your_domain_name.com
DocumentRoot /var/www/html/omeka/
ErrorLog /var/log/httpd/omeka_error.log
CustomLog /var/log/httpd/omeka_access.log combined
</VirtualHost>
Make sure to replace your_domain_name.com with your actual domain name.
Save the file and exit. Reload the Apache service for changes to take effect:
sudo systemctl reload httpd
Open your web browser and enter your domain name or IP address. You should see the Omeka installation page. Follow the on-screen instructions to complete the installation.
Congratulations! You have successfully installed Omeka on the latest version of Fedora CoreOS. You can now use this powerful platform to create digital exhibits and showcase your cultural heritage materials and research.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
