How to Install Omeka S on POP! OS

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.

Prerequisites

Before starting with the installation process, ensure that you have the following prerequisites:

Step 1: Install LAMP Stack

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

Step 2: Create a MySQL Database and User

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;

Step 3: Download and Install Omeka S

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

Step 4: Configure the Omeka S

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.

Step 5: Configure Apache for Omeka S

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

Step 6: Access Omeka S via Web Browser

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.
