Omeka S is a free and open-source web-publishing platform that is primarily used by libraries, archives, museums, and scholars to showcase their collections. In this tutorial, we will guide you step by step on how to install Omeka S on the POP! OS latest release.
Before starting with the installation process, ensure that you have the following prerequisites:
Omeka S is a PHP-based web application that requires a web server, a database server, and PHP support to function correctly. Therefore, the first step is to install the LAMP stack on your server. To do that, run the following commands:
sudo apt update
sudo apt install apache2 mysql-server php php-mysql libapache2-mod-php php-json php-gd php-xml
During the installation process, you will be prompted to set up a root password for the MySQL database server. Enter a strong and secure password and remember it for future use.
After installing the LAMP stack, start the Apache and MySQL services and enable them to start at boot time by executing the following commands:
sudo systemctl start apache2
sudo systemctl enable apache2
sudo systemctl start mysql
sudo systemctl enable mysql
Next, you need to create a new MySQL database and user for Omeka S. To do that, log in to the MySQL server as the root user using the following command:
sudo mysql -u root -p
Enter the MySQL root password that you set in the previous step.
Once you are logged in, create a new database by running the following command:
CREATE DATABASE omeka_db CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
Replace omeka_db with the name of your desired database.
Next, create a new MySQL user and grant all privileges to the newly created database by running the following commands:
CREATE USER 'omeka_user'@'localhost' IDENTIFIED BY 'your_password';
GRANT ALL PRIVILEGES ON omeka_db.* TO 'omeka_user'@'localhost';
FLUSH PRIVILEGES;
Replace omeka_user and your_password with your desired username and password.
Finally, exit the MySQL command prompt by running this command:
exit;
Now that you have set up the LAMP stack and created a new MySQL database and user, you can download and install Omeka S on the POP! OS server.
First, go to the official website of Omeka S and download the latest release. You can use the following command to download the latest version:
wget https://download.omeka.org/s/omeka-s-3.1.2.zip
Replace omeka-s-3.1.2.zip with the latest release if there is a new release.
Once the download is complete, extract the downloaded file by running the following command:
unzip omeka-s-3.1.2.zip
Next, move the extracted directory to the Apache webserver root directory:
sudo mv omeka-s-3.1.2 /var/www/html/omeka
Now you need to configure the Omeka S according to your needs. You can do that by modifying the .env file in your Omeka S installation directory:
sudo nano /var/www/html/omeka/.env
Here you will find all the settings that need to be set for Omeka S to function correctly. Generally, you will only need to modify the following settings:
APP_ENV=production
APP_SECRET=
OMEGA_DB_NAME=omeka_db
OMEGA_DB_USER=omeka_user
OMEGA_DB_PASSWORD=your_password
OMEGA_DB_HOST=localhost
OMEGA_BASE_URL=https://domain.name/omeka
After modifying the settings, save and close the file.
Next, create an Apache virtual host file for Omeka S to configure the webserver. You can use the following command to create a new virtual host file:
sudo nano /etc/apache2/sites-available/omeka.conf
Paste the following configuration to the file:
<VirtualHost *:80>
ServerName domain.name
DocumentRoot /var/www/html/omeka
<Directory /var/www/html/omeka>
AllowOverride All
</Directory>
ErrorLog ${APACHE_LOG_DIR}/omeka_error.log
CustomLog ${APACHE_LOG_DIR}/omeka_access.log combined
</VirtualHost>
Make sure to replace domain.name with your actual domain name.
Once you are done with the configuration, save, and close the file.
Next, enable the newly created virtual host and the required Apache modules by running the following commands:
sudo a2ensite omeka.conf
sudo a2enmod rewrite headers env dir mime setenvif ssl
Restart the Apache service to apply the changes:
sudo systemctl restart apache2
You have successfully installed Omeka S on POP! OS. Now, open your web browser and access Omeka S by entering the following URL in the address bar:
http://domain.name/omeka
Replace domain.name with your actual domain name.
You will see the Omeka S installation wizard, follow the on-screen instructions to complete the installation.
In this tutorial, you learned how to install Omeka S on POP! OS. By following this tutorial, you have now a fully functional Omeka S website up and running. With your collection of content ready to go, you can now focus on creating an engaging web presence.
