Omeka S is a web publishing platform that helps you create and share online exhibits, digital collections, and more. If you're running Fedora CoreOS and want to install Omeka S, you're in luck. This tutorial will walk you through the installation process step-by-step.
First, we need to install a web server and PHP. In this case, we'll be using Apache and PHP-FPM. Use the following command to install them:
sudo rpm-ostree install httpd php php-fpm
Next, we need to install MariaDB, which is a popular open-source database management system. Use the following command to install it:
sudo rpm-ostree install mariadb-server mariadb
After installation, start the MariaDB service using the following command:
sudo systemctl start mariadb
Omeka S requires a MariaDB instance and a user with full privileges on that instance. We'll create both of them now.
Log in to MariaDB console using the following command:
sudo mysql -u root -p
Enter your root password when prompted. Once logged in, create a new database and user using the following commands:
CREATE DATABASE omeka_s;
CREATE USER 'omeka_user'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON omeka_s.* TO 'omeka_user'@'localhost';
FLUSH PRIVILEGES;
Replace password with a strong password of your choice.
Exit the MariaDB console using the following command:
exit;
We need to configure Apache to serve Omeka S. Create a new virtual host configuration file for Omeka S using the following command:
sudo vi /etc/httpd/conf.d/omeka_s.conf
Add the following lines to the configuration file:
<VirtualHost *:80>
ServerName your-domain-name
DocumentRoot /var/www/html/omeka_s
<Directory /var/www/html/omeka_s>
AllowOverride All
</Directory>
</VirtualHost>
Replace your-domain-name with your domain name or IP address. Save and close the file.
Download the latest stable version of Omeka S from the official website using the following command:
sudo wget https://omeka.org/s/download/omeka-s-latest.zip
Extract the zip file using the following command:
sudo unzip omeka-s-latest.zip -d /var/www/html/
Rename the extracted folder to omeka_s using the following command:
sudo mv /var/www/html/omeka-s-* /var/www/html/omeka_s
Change the ownership of the Omeka S files to Apache user using the following command:
sudo chown -R apache:apache /var/www/html/omeka_s
Create a new .env file by copying the .env.local file included with the Omeka S distribution using the following command:
sudo cp /var/www/html/omeka_s/.env.local /var/www/html/omeka_s/.env
Edit the .env file using any text editor and set the following configuration variables:
APPLICATION_ENV = production
DATABASE_NAME = omeka_s
DATABASE_USER = omeka_user
DATABASE_PASSWORD = password
DATABASE_HOST = localhost
BASE_URL = http://your-domain-name/
Replace password with the password you set in step 3, and your-domain-name with your domain name or IP address.
Finally, reload Apache configuration using the following command:
sudo systemctl reload httpd
If SELinux is enabled on your system, you may need to adjust the SELinux settings to allow Apache to access the Omeka S files. Use the following command to set the correct SELinux context:
sudo semanage fcontext -a -t httpd_sys_rw_content_t "/var/www/html/omeka_s(/.*)?"
sudo restorecon -Rv /var/www/html/omeka_s
That's it! You should now have a working Omeka S installation on your Fedora CoreOS machine. Point your web browser to http://your-domain-name/ to access Omeka S and start creating digital collections and exhibits.
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!
