How to Use Vultr’s WP Squared Marketplace Application

Deploy and configure WP Squared on Vultr with WHM setup, DNS, SSL, and WordPress site management.

WP Squared is a cPanel/WHM-based WordPress management platform designed for hosting and managing multiple WordPress sites on a single server. It combines the power of cPanel’s hosting control panel with WordPress-specific optimizations, automated SSL via Let’s Encrypt, and streamlined site creation workflows. The Vultr Marketplace provides a pre-configured WP Squared instance, enabling quick deployment and setup on a Vultr server.

This guide explains deploying and using Vultr’s WP Squared Marketplace Application. You will deploy an instance, configure DNS and SSL, complete the WHM initial setup, create WordPress sites, and implement best practices for production deployments.

Deploy Vultr’s WP Squared Marketplace Application

Log in to your Vultr Customer Portal and click the Deploy Server button.
Select your preferred server type.
Choose a server location.
Select a server plan with at least 2GB RAM and 2 CPU cores for a few sites, or 4GB RAM and 4 CPU cores for multiple WordPress sites.
Click the Configure button to proceed.
Under Marketplace Apps, search for WP Squared and select it as the Marketplace Application.
Select the Limited Login option from the Additional Features section to create a limited user with sudo access.
Review your configurations and click the Deploy Now button to start deployment.

Note

It may take up to 15 minutes for your server to finish installing WP Squared.
After the instance shows the status of Running, navigate to the Server Overview page and copy the SSH connection details.

Initial Setup and Configuration

After deployment, configure DNS, verify the installation, and complete the WHM initial setup before creating WordPress sites.

Create a DNS A record pointing to your server’s IP address, such as wpsquared.example.com.
Connect to your Vultr server instance over SSH using the connection details from the Server Overview page.

Verify WP Squared Installation

Check the cPanel service status.
console
```
$ sudo /usr/local/cpanel/cpanel -V
```
This displays the installed cPanel version.
Verify the license is active.
console
```
$ sudo /usr/local/cpanel/cpkeyclt
```
Access WHM by visiting https://YOUR_SERVER_IP:2087 in a web browser.
You’ll see a browser warning because of the self-signed certificate. Bypass it to continue.

Configure Firewall Security

Secure your server by configuring the firewall to allow only necessary traffic.

Allow SSH connections.
console
```
$ sudo ufw allow OpenSSH
```

Allow HTTP and HTTPS traffic.

console

$ sudo ufw allow 80/tcp
$ sudo ufw allow 443/tcp

Allow WHM and cPanel ports.

console

$ sudo ufw allow 2087/tcp
$ sudo ufw allow 2083/tcp

Enable the firewall.
console
```
$ sudo ufw enable
```
Verify firewall status.
console
```
$ sudo ufw status
```

Complete WHM Initial Setup

Open the WHM interface in your browser.
```
https://wpsquared.example.com:2087/
```
If DNS is not yet configured, use your server’s IP address instead.
Log in with the root account credentials from the Server Overview page.
Accept the cPanel & WebHost Manager end user agreement.
Enter your contact email address and nameservers. If using Vultr DNS, enter:
- ns1.vultr.com
- ns2.vultr.com
Click Finish to complete the initial setup.

Change Server Hostname

In WHM, navigate to Networking Setup > Change Hostname.
Enter your FQDN (e.g., wpsquared.example.com).
Click Change to apply.

Note

Do not use a hostname that begins with www, a number, or ends with a hyphen. Use a unique FQDN that identifies the server and is not used by any hosted site.

Configure SSL with AutoSSL

WP Squared automatically manages SSL certificates using Let’s Encrypt.

In WHM, navigate to SSL/TLS > Manage AutoSSL.
Ensure a provider is selected (Let’s Encrypt or cPanel Sectigo).
Click Run AutoSSL For All Users to issue certificates for all configured domains.
SSL certificates will be automatically renewed before expiration.

Create WordPress Sites

Set up WP Squared accounts and create WordPress websites.

Create an Account in WHM

In WHM, click Account Functions > Create a New Account.
Enter the account details:
- Domain: The domain for the WordPress site
- Username: Account username (8 characters max)
- Password: Strong password
- Email: Contact email
Click Create to provision the account.
Click Go To WP Squared to access the site setup.

Create a WordPress Site

Access WP Squared via WHM or directly at:
```
https://wpsquared.example.com:2083/
```
Log in with the account credentials you created.
Choose your language and click Next, select privacy preferences.
Choose your account type and click Continue.
Select a WordPress theme and click Next, Name Your Site.
Enter your website name and tagline.
Click Finish Setup and wait for installation to complete.
Your WordPress site is now live at your configured domain.

Follow the same setup wizard to create additional WordPress sites.
