How to install Omeka CMS on Ubuntu Linux with Apache support
As described above, Omeka Classic is a modern, lightweight web publishing platform (CMS) for sharing digital collections and creating media-rich content.
Below is how to install it on Ubuntu Linux.
Install Apache2 HTTP Server on Ubuntu
Apache2 HTTP Server is the most popular web server in use. So, install it since Omeka CMS needs it.
To install Apache2 HTTP on the Ubuntu server, run the commands below.
sudo apt update sudo apt install apache2
After installing Apache2, the commands below can stop, start, and enable the Apache2 service to always start up with the server boots.
sudo systemctl stop apache2.service sudo systemctl start apache2.service sudo systemctl enable apache2.service
To test the Apache2 setup, open your browser and browse to the server hostname or IP address. You should see the Apache2 default test page, as shown below. When you see that, then Apache2 is working as expected.
http://localhost
Install MariaDB Database Server
MariaDB database server is a great place to start when looking at open-source database servers for Magento. To install MariaDB, run the commands below.
sudo apt-get install mariadb-server mariadb-client
After installing MariaDB, the commands below can stop and start the service and enable it to start when the server boots.
Run these on Ubuntu 16.04 LTS
sudo systemctl stop mysql.service sudo systemctl start mysql.service sudo systemctl enable mysql.service
Run these on Ubuntu 17.10 and 18.04 LTS
sudo systemctl stop mariadb.service sudo systemctl start mariadb.service sudo systemctl enable mariadb.service
After that, run the commands below to secure the MariaDB server by creating a root password and disallowing remote root access.
sudo mysql_secure_installation
When prompted, answer the questions below by following the guide.
- Enter current password for root (enter for none): Press the Enter
- Set root password? [Y/n]: Y
- New password: Enter the password
- Re-enter new password: Repeat password
- Remove anonymous users? [Y/n]: Y
- Disallow root login remotely? [Y/n]: Y
- Remove test database and access to it? [Y/n]: Y
- Reload privilege tables now? [Y/n]: Y
Restart MariaDB server
Type the commands below to log on to the MariaDB server to test if MariaDB is installed.
sudo mysql -u root -p
Then, type the password you created above to sign on. If successful, you should see a MariaDB welcome message.
Install PHP 7.2 and Related Modules
PHP 7.2 may not be available in Ubuntu default repositories. To install it, you must get it from third-party repositories.

To test PHP 7.2 settings with Apache2, create a phpinfo.php file in the Apache2 root directory by running the commands below
sudo nano /var/www/html/phpinfo.php
Then, type the content below and save the file.
<?php phpinfo( ); ?>
Save the file. Then browse to your server hostname followed by /phpinfo.php
http://localhost/phpinfo.php
