To begin a new installation or upgrade to a newer version, download the EASA installer.
The new installation process involves the following sequence of steps:
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, especially when migrating to a newer version of EASA, please email email@example.com.
If another web server such as Microsoft Internet Information Services (IIS) is already installed and listening on port 80, the EASA Server will install itself on a different port displayed during installation. If no other web server software is running, the EASA Server will install itself 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, follow one of these suggestions:
On computers running Windows the EASA Server is installed and configured automatically by default to run as a 'service'. To manually configure the service to use a particular user account to log in, see Run EASA as a Service.
On computers running Linux EASA can be set up to run as a service after completing the installation as described in Run 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 beforehand if EASA is 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 the distribution by default but is required for correct operation of Compute Servers. If csh is not included in the distribution, simply install EASA and afterwards, check the 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.
To upgrade from a previous version of EASA:
These Help Pages will refer to the selected folder as <EASAROOT> or the installation folder.
At the 'Select Installation Type' window, choose from the following:
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 or <SERVERDATA> window appears.
The full path of the data folder cannot contain more than 218 characters.
Complete the following two steps for 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 check the configuration before installation begins:
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 is chosen. For remote access, the correct domain name must be substituted for ‘localhost’. See Test the EASA Web Pages.
