WHM & cPanel Server Support That Goes Beyond the Control Panel
A cPanel server can look fine from the dashboard while something underneath is causing websites to fail, emails to queue, or services to stop responding.
Onlive Server provides WHM cPanel support and server management for businesses, agencies, developers, resellers, and website owners who need help with installation, configuration, migration, security, or troubleshooting.
From setting up a new WHM server to resolving Apache, PHP, MySQL, DNS, or Exim issues, we work on the server environment behind the panel.
WHM Support for the Work You Actually Need Done
You may need a complete WHM setup. Or perhaps one service has stopped working and you need someone to find out why. Our support covers the following server and account tasks.
WHM & cPanel Installation
Install and configure cPanel & WHM on a supported VPS or dedicated server.
Server Configuration
Set up hostname, nameservers, packages, services, PHP, Apache and other required components.
Account Management
Create, modify, suspend, transfer and manage individual cPanel accounts.
DNS Configuration
Handle nameservers, DNS zones, A, MX, CNAME and TXT records.
Email Troubleshooting
Investigate Exim queues, SMTP problems, mail routing and domain email configuration.
PHP & Apache Issues
Work through PHP errors, PHP-FPM problems, Apache configuration and website service failures.
Database Support
Troubleshoot MySQL/MariaDB connections, permissions, imports and related website errors.
WHM & cPanel Migration
Move cPanel accounts, websites, databases, email and configuration to another server.
WHM Is the Server Side of cPanel
If you’re managing a cPanel server, you’ll normally work with two interfaces.
WHM controls the server and hosting accounts. cPanel gives individual hosting users access to their own websites, domains, email, databases and files.
WHM
Web Host Manager
Used by server administrators and hosting providers to manage server-wide settings and hosting accounts.
cPanel
Website & Hosting Account Tools
Used by individual hosting account owners to manage the websites and services available within their accounts.
A Website Error May Start in cPanel, but the Fix Could Be on the Server
For example, a customer may report that their website is returning a 500 error. The cause might involve PHP settings inside the account—or it could be an Apache configuration, PHP-FPM process, permission problem, or server resource issue.
New WHM Server? Get the Initial Setup Right
A fresh cPanel installation needs more than running the installer and logging in.
We can handle the initial configuration, including:
The goal is straightforward: get the server into a usable state before customer websites and production workloads are moved onto it.
cPanel Account Creation and Management
Running multiple websites from one server becomes much easier when each customer or project has its own cPanel account.
We can help with:
- ✓ New cPanel account creation
- ✓ Package assignment
- ✓ Account resource limits
- ✓ Domain configuration
- ✓ Account suspension
- ✓ Account transfers
- ✓ Account restoration
- ✓ Website migrations
- ✓ Account-level troubleshooting
This is particularly useful for hosting resellers, agencies and developers managing several client websites.
cPanel Migration Without Rebuilding Everything
Moving from one cPanel server to another doesn’t normally mean starting from zero.
Move the Parts That Matter
A proper migration can move the important parts of an account, including:
We first review the source and destination environments, transfer the required data, check the migrated account and test the website before the final DNS change.
Review accounts, test websites and verify required services.
Review, Transfer, Test, Then Switch
Check the source and destination server environments.
Move the required account data and configuration.
Check websites, email and other account services.
Make the final DNS change after validation.
For larger migrations, individual accounts can be moved and tested in stages rather than switching everything at once.
DNS Problems Can Affect Both Website and Email
A DNS mistake can make a perfectly healthy server appear broken.
For example, the website may load correctly while email stops working because the MX record points somewhere else. A missing A record can prevent a domain from resolving to its intended IPv4 address.
One Domain. Different Destinations.
DNS Records, Nameservers & Email Authentication
We can work with the following DNS records and related configurations.
Map hostnames to IPv4 addresses.
Map hostnames to IPv6 addresses.
Direct incoming email to mail exchangers.
Create DNS aliases for hostnames.
Publish text-based DNS information.
Publish authorized mail senders using TXT records.
Publish keys used to verify email signatures.
Publish email authentication policies and reporting settings.
Configure authoritative DNS delegation.
Review and manage a domain’s DNS records.
Website Works, but Incoming Email Fails
The web hostname resolves to the intended server.
The MX record may point to the wrong mail provider.
Review MX targets, related address records and mail settings.
If your website and email use different providers, we can also help keep the DNS configuration separated correctly.
PHP, Apache and Website Errors
A website showing HTTP 500, 502 or 503 does not always have a problem with its application code.
The cause may be:
- 01PHP configuration
- 02PHP-FPM
- 03Apache
- 04File permissions
- 05Missing PHP extensions
- 06Memory limits
- 07Service failures
- 08Incorrect virtual-host configuration
- 09Server resource pressure
Instead of treating every error as a WordPress or application problem, we check the server components involved in serving the request.
MySQL and MariaDB Support
Database errors can stop an otherwise healthy website from working.
We can troubleshoot issues such as:
- Database connection failures
- Incorrect database credentials
- User permission problems
- MySQL/MariaDB service issues
- Database imports
- Database exports
- phpMyAdmin access problems
- Database-related website errors
For larger databases, the server’s available CPU, RAM, storage performance and database configuration may also need to be reviewed.
Secure Your WHM Server
WHM gives administrators considerable control over the hosting environment. That control needs to be protected.
We can assist with server-level security tasks such as:
- ✓Firewall configuration
- ✓SSH access controls
- ✓Security updates
- ✓SSL/TLS configuration
- ✓Brute-force protection
- ✓User-access review
- ✓Service exposure checks
- ✓Malware-related investigation
- ✓Backup configuration
Security settings should match the server’s actual workload. Blocking a required service with an overly restrictive firewall rule is not a useful security improvement.
Backup Configuration and Recovery
A backup is useful only when the required data can actually be restored.
For supported cPanel environments, we can help review backup configuration for:
- Website files
- Databases
- cPanel accounts
- Server configuration
- Backup retention
- Backup storage
For production websites, maintaining an independent backup outside the primary server is also worth considering.
