DSpace is an open source repository software package typically used for creating open access repositories for scholarly and/or published digital content.
DSpace by default uses port 8080
Koha is a fully featured, scalable library management system.
Koha by default uses two ports that is 80 and 8080.
By this, you realise that there is a conflict with regards to the ports.
So, what we do here is to change the ports for Koha to different ports
Adding Koha ports
Open following file and add ports
sudo vi /etc/apache2/ports.conf
Type the following lines below such that they can work for both OPAC and Staff interface instead of ports 80 and 8080 since by default are also used by DSpace.
NOTE: You can use any different port of your own choice as long as they don't conflict with the ones already in use.
Listen 8000
Listen 8001
Restart Apache,
sudo service apache2 restart
Open following link in a broswer to confirm that the ports you have added are working,
http://127.0.1.1:8000
http://127.0.1.1:8001
After that you can start installation of DSpace.
