II. Install ESET Remote Administrator Server on the first node

Shared storage required

Shared storage must be located on your first node for a successful installation.

  1. Double-click the installer file. Click Next
     
  2. Select the check box next to This is a cluster and click Next.

    We recommend using a CNAME during installation as it is easier to remember than a cluster listener name.

V. Install ESET Remote Administrator Web Console

  1. Install the ESET Remote Administrator Web Console (ERA Web Console).
     
  2. Edit the following file in Notepad: 

    C:\Program Files\Apache Software Foundation\Tomcat 7.0\webapps\era\WEB-INF\classes\sk\eset\era\g2webconsole\server\modules\config\EraWebServerConfig.properties

    Change “server_address” to your CNAME cluster listener address.
     
  3. Restart (or start) the Tomcat service.
     
  4. Log into ERA Web Console. How do I open the ESET Remote Administrator Web Console?
