Introduction
Before DSpace can be installed and setup we have to prepare the server with the software needed by DSpace.
- Print this page and manually tick off the steps as you complete them.
Requirements
- It is essential that you have first completed the installation of Ubuntu. If you have not, please do so now.
Step 1. Login to the remote server
Step 2. Become the "root" user
Step 3. Install Java Software Dependencies
Step 4. Setup Maven Java Installer
Step 5. Setup Tomcat Java Webapp Server
Step 6. Install PostgreSQL
Step 7. Setup the Postfix mail server
Step 8. Setup the environment variables
Step 9. Check the installation
Next Procedure
Congratulations, you now have a very high performance java with postgresql, webapp server. The next step is to install and setup DSpace.
- If everything is OK, then proceed to the installation of DSpace itself.

We have more than enough compute muscle.

Our memory usage stabilised when we stopped using the JSPUI. However after the upgrade to DSpace 1.8.2 and enabling discovery we are back to a memory intensive system.
