CyberPanel and aaPanel get compared frequently, but the core difference between them isn't the interface โ it's the choice of web server. CyberPanel runs OpenLiteSpeed by default; aaPanel runs Nginx. For WordPress deployments, that distinction has meaningful performance implications and is worth understanding before you start installing anything.
OpenLiteSpeed vs Nginx: Which Is Faster for WordPress?
Nginx is the most widely deployed web server today โ stable, well-documented, with a large community. But it doesn't handle caching natively. WordPress page caching on Nginx has to be implemented at the application layer through plugins like W3 Total Cache or WP Rocket.
OpenLiteSpeed is the open-source version of LiteSpeed Enterprise, and its caching works differently. LSCache operates at the web server level โ it intercepts requests and serves cached static versions of dynamic pages before they ever reach PHP or the database. The performance gap between server-level caching and plugin-based application caching is significant. On equivalent VPS hardware, OpenLiteSpeed + LSCache typically handles WordPress concurrency noticeably better than Nginx with a caching plugin.
HTTP/3 and QUIC support is another advantage โ OpenLiteSpeed enables these by default. Getting HTTP/3 working on Nginx still requires a custom compile in most environments and is more involved to configure.
The tradeoff is that OpenLiteSpeed uses different configuration syntax from Nginx. Nginx tutorials don't translate directly, troubleshooting requires LiteSpeed-specific documentation, and the available learning resources are thinner.
Bottom line: for pure WordPress and WooCommerce hosting, CyberPanel has a higher performance ceiling than aaPanel. If you also need to run Docker applications or you're more comfortable with Nginx, aaPanel is the lower-friction option.
System Requirements
CyberPanel has one important constraint: it must be installed on a clean system. Installing it on a server already running Apache, Nginx, or another control panel will cause port conflicts. The official configuration doesn't support co-existing panels.
Recommended operating systems:
Minimum 1 GB RAM, though 2 GB is more stable for WordPress + MySQL + LSCache. WooCommerce should start at 4 GB.
Connect to the Server and Update the System
SSH connection and system update commands are standard โ just the essentials here:
# Connect to the server
ssh root@your-server-ip
# Update on Ubuntu / Debian
apt update && apt upgrade -y
# Update on AlmaLinux / Rocky Linux
dnf update -y
# Set timezone
timedatectl set-timezone Asia/Shanghai
Complete the update before running the installer to avoid dependency version conflicts.
Installing CyberPanel
Download and run the official installation script:
wget -O installer.sh \
https://cyberpanel.net/install.sh
chmod +x installer.sh
bash installer.sh
The installation is interactive and will ask a few key questions. Here's what each one means:
Choose a version: OpenLiteSpeed or LiteSpeed Enterprise
For most users, choose OpenLiteSpeed (enter 1). It's free and fully capable for personal sites and small-to-medium commercial sites. LiteSpeed Enterprise delivers better performance at higher concurrency but requires a license โ a single-domain free trial is available, multi-domain requires purchase. If you're unsure, start with OpenLiteSpeed and upgrade later if needed.
Full installation vs Basic (PowerDNS, Postfix, Pure-FTPd)
If you need to host domain DNS or run a mail server on this machine, choose Full installation. If you're only running websites and don't need email services, Basic reduces resource usage and attack surface. For most website hosting scenarios, Full installation is the safer default โ fewer gaps to fill in later.
Redis and Memcached
Leave both enabled. Redis makes a measurable difference for WordPress object caching and only takes minimal configuration to activate after installation.
Installation takes roughly 5โ15 minutes. When complete, the terminal displays your login credentials:
CyberPanel Successfully Installed
Current Disk usage : ...
Current RAM usage : ...
CyberPanel admin's password: xxxxxxxx
To Login to CyberPanel:
https://SERVER-IP:8090
Save the password โ you'll need it for first login.
Opening Firewall Ports
Same as with aaPanel โ ports need to be opened in two places: your cloud provider's security group and the server's own firewall.
Required ports:
| Port | Purpose |
|---|---|
| 22 | SSH |
| 80 | HTTP |
| 443 | HTTPS |
| 8090 | CyberPanel control panel |
| 8443 | HTTPS panel access (optional) |
| 53 | DNS (if enabled) |
Ubuntu firewall commands:
ufw allow 22
ufw allow 80
ufw allow 443
ufw allow 8090
ufw enable
Logging In and Creating a Website
Open https://your-ip:8090 in a browser. Log in with the admin account and the password shown at the end of installation. The browser will warn about an untrusted certificate โ ignore it and proceed.
Change the admin password immediately after first login. Don't put this off.
To create a site: go to "Websites" โ "Create Website" in the left sidebar. Enter your domain, select PHP 8.2, and check "SSL" to have the system automatically request a Let's Encrypt certificate. You can create the database in this same step or add it separately afterward.
One-Click WordPress Installation
CyberPanel includes a built-in WordPress installer โ no manual file upload required. In the website management page, find your domain and click "WP+LSCache," fill in the WordPress admin details, and click install. When it finishes, you can log in to the WordPress dashboard immediately.
This one-click installer automatically installs and activates the LiteSpeed Cache plugin. That's the critical part โ without it, LSCache caching does not activate, and you lose CyberPanel's main performance advantage.
LSCache Configuration: CyberPanel's Core Advantage
After the LiteSpeed Cache plugin is installed, a few settings in the WordPress LiteSpeed Cache panel are worth configuring immediately:
Enable page caching โ this is the most important setting. With it on, dynamic page requests are served directly from the server cache without touching PHP or the database.
Image lazy loading and CSS/JS minification and combining are under the "Page Optimization" tab and contribute meaningfully to page load speed.
CDN integration: if you're using Cloudflare, enter your Cloudflare API credentials under the "CDN" tab. This lets WordPress cache purges also clear the CDN cache simultaneously, preventing stale content from being served.
HTTP/3 is enabled by default and requires no additional configuration. You can verify it's working by checking the Network tab in Chrome DevTools โ requests should show the protocol as h3.
Security Hardening
General SSH key authentication and firewall configuration are covered in the aaPanel guide โ this section focuses on what's specific or especially important for CyberPanel.
Change the default panel port
In CyberPanel settings, change 8090 to a non-default port. This reduces exposure to automated scanning tools looking for known panel ports.
Enable two-factor authentication
Turn on 2FA in account settings and bind it with an Authenticator app.
Keep CyberPanel updated
CyberPanel has had security vulnerabilities in the past. Staying current on updates is one of the most important security measures. Check for updates in the panel, or run from the command line:
cd /usr/local/CyberCP
git pull origin stable
python manage.py migrate
Automated backups
Configure scheduled backups under "Backup" โ daily is recommended. Set up a remote backup destination (FTP or S3) as well. Local-only backups don't protect against disk failure or a compromised server.
Common Issues
Installation fails: the most common cause is an existing web server or control panel on the system. CyberPanel requires a clean install. Insufficient RAM (under 1 GB) will also interrupt the installation.
Can't access port 8090: check both the cloud security group and the server firewall โ both need to allow this port. Run ss -tlnp | grep 8090 to confirm whether LiteSpeed is listening.
SSL issuance fails: confirm your domain's DNS is resolving to the current server IP. Let's Encrypt validates ownership by making an external request to port 80.
503 errors: usually means the OpenLiteSpeed service isn't running. Restart it with systemctl restart lsws.
CyberPanel vs aaPanel: How to Choose
| Attribute | CyberPanel | aaPanel |
|---|---|---|
| Web server | OpenLiteSpeed | Nginx / Apache |
| WordPress performance ceiling | Higher | Good |
