Requirements

The Nexus Server supports x64-bit versions of Windows, Windows Server, and Linux (Debian-based and RHEL-based) operating systems. It can be installed on a physical device, a virtual machine, or a cloud server. A minimum of 1 CPU is required, although 2 CPUs or more are recommended for optimal performance. The server also requires a minimum of 4 GB of RAM and at least 50 GB of free disk space. An exception is required for the system firewall, if active, to permit traffic on the Nexus Server port.

Installation Path
The installation path will be set to the following location and must not be changed:

• Windows: c:\xcware\nexus-server
• Linux: /xcware/nexus-server

Installation User
The installation or update procedure must be performed by an Administrator on Windows and by the root user on Linux systems.

Nexus Image Repository Strategy

Before setting up your xcware environment, you need to define your Nebula image repository strategy, which also includes selecting the appropriate installation packages. The xcware platform can be deployed in various configurations, including Public, Private, Hybrid, Edge, On-Premises, Multi, or Mixed environments. You can even configure multiple Nexus servers for different use cases, which will influence how you deploy the Nebula system. There are two package options available for this purpose:

1. Rollout Package
   The Rollout Package includes the Nexus Server and Nebula image repositories, making it the preferred choice for On-Premises, Private, or Hybrid environments.
   
   
2. Server Package
   The Server Package includes only the Nexus Server, with the Nebula image repository hosted on xcware.com, making it the preferred choice for Cloud, Edge, or Mixed environments.
   
   

Installing the Nexus Server

1. Download the package from our Downloads Section.
   
   
   xcware Repository
   If your environment has Internet access, you can install the Nexus Server using the Server Package. In this case, you will need to set "https://xcware.com/c/_data/" as your repo_address in the configuration.
2. Extract the archive to the installation path specified in the requirements.
   
   
3. To verify the folder structure, ensure the following file exists:
   • Windows
     

     c:\xcware\nexus-server\web\c\index.html

     
     
   • Linux
     

     /xcware/nexus-server/web/c/index.html

   
   
4. Now we need to install the Nexus Server Service. For that, open a terminal as an administrator and execute the following command:
   • Windows
     

     powershell.exe c:\xcware\nexus-server\register-nexus-server.ps1

     
     
   • Linux
     

     bash /xcware/nexus-server/register-nexus-server.sh

   
   
5. That's it! You have successfully installed the Nexus Server.
