Download the EASA installer package either to begin a new installation, or to upgrade to a newer version.
The new installation process requires the following:
The process to upgrade an existing installation to a newer version requires the following:
The EASA Help Pages provide detailed instructions on installing and testing the EASA Server and also provide solutions to many common problems. However if further assistance is needed, please email firstname.lastname@example.org.
Before providing instructions on installing the EASA Server, there are a few issues regarding the installation of EASA that need to be addressed in order for the installation process to proceed smoothly.
If another web server such as Microsoft Internet Information Services (IIS) is already installed and listening on port 80; the EASA Server will be installed on a different port which is displayed during the installation process. If no other web server software is running, the EASA Server will be installed on the default (HTTP) port 80.
Tomcat™ (6.x or 8.x) is third party software that is required and installed as part of the EASA Server.
However if Tomcat is already installed and running, we suggest one of two actions:
On computers running Windows the EASA Server is installed and configured by default to run as a 'service'. On computers running Linux EASA can be set up to run as a service after completing the installation as described in Running EASA as a Service.
Note: Installing the EASA Server as a service during the EASA installation is completely automatic on Windows. If needed, manually configure the service to use a particular user account to login, as described in Running EASA as a Service.
The EASA installer for Linux computers does not include a Java Runtime Environment (jre) as it did with past versions. A jre version 1.7 or later must be installed on the computer prior to installing EASA for the installation to work properly.
Linux distributions such as Ubuntu Server should have all of the packages required to run the EASA installer and to run the EASA Server. One exception to this is C Shell (csh), which may not be included in your distribution by default and is required for correct operation of Compute Servers. If you do not know if csh is included in your distribution, simply install EASA and afterwards, check the EASA→Administrator→Configure→Compute Servers EASA web page.
If the local Compute Server is showing as 'inactive', it is likely that csh needs to be installed, as follows:
Please follow the step-by-step instructions provided below to install the EASA software.
Note: To upgrade from a previous version of EASA: first stop the EASA Server if it is running, and then remove any Start EASA or Start Tomcat shortcuts from the startup folder.
Note: The selected folder will be referred to as <EASAROOT>
Next appears the 'Select Installation Type' window which offers three choices:
Select one and Click on Next to continue.
For Custom and Advanced installations, the Select Components window appears. Choose from the following components:
The 'Data Folder' window appears next and prompts for a folder in which to save User data. This folder is also referred to as <SERVERDATA>. Make your selection and then click on Next to continue
Note: The full path of the 'Data Folder' cannot contain more than 218 characters.
The following two steps are completed only when performing an Advanced installation. These steps allow for installing multiple EASA Server installations on the same computer. In this case, each EASA Server must have a unique port number and a unique Windows service name.
Now we check the configuration before installation begins:
Note: The 'Completing Setup' window will display the URL or address that can be used to access EASA from the EASA Server. Please note if a port number other than 80 has been chosen. To access EASA from a different computer, the correct domain name must be substituted for ‘localhost’. See Testing the EASA Web Pages for details.
