# Quick Installation Using All-in-one Script

This chapter guides you through the process of installing both the vPlus server and node on a new machine using the provided installation script.

## Prerequisites

Ensure your system meets the following requirements:

* Operating System: AlmaLinux 9 (preferred), Red Hat Enterprise Linux (RHEL) 8, or CentOS Stream 8
* Hardware: Minimum 4 CPU cores, 8 GB RAM, and 100 GB storage
* Network: Stable internet connection
* Permissions: Root or sudo access

{% endhint %}

## Installation Steps

1.  **Download the Installation Script**

    Obtain the vPlus installation script from the [Catalogic MySupport website](https://mysupport.catalogicsoftware.com/).
2.  **Run the Installation Script**

    Execute the script with root privileges:

```bash
sudo ./DPX-vPlus-online-install.sh
```

During the installation process, you will be prompted to:

* Set a password for the vPlus server "admin" user account
* Set a password for the database root account

{% hint style="info" %}
<mark style="color:blue;">**Important**</mark><mark style="color:blue;">.</mark> Make sure to securely store both passwords as they will be needed for future administrative tasks.
{% endhint %}

The script will automatically install both the vPlus server and node components on your machine.

{% hint style="warning" %}
<mark style="color:orange;">**Attention!**</mark> If the installation fails on step "Check if port forwarding from 443 to 8181 is already set", disable the firewall and rerun the installation command.
{% endhint %}

## Post-Installation Steps

After successful installation, you can access the vPlus server using `https://IP_OF_YOUR_MACHINE`. The local node will be automatically registered and running.

{% hint style="info" %}
<mark style="color:blue;">**Note.**</mark> For security reasons, the default password (vPr0tect) has been replaced by the password you set during installation.
{% endhint %}

After the initial log in, you can configure single sign-on using LDAP or Keycloak.

Remember to prepare your staging space as described in the [Staging space configuration](../common-tasks/staging-space-configuration).

Now proceed with the Initial configuration instructions, to configure access to the hypervisors and backup destinations.
