Overview of Modern Web Hosting & Control Panels
Managing production web servers at scale requires choosing the right hosting stack. Whether utilizing traditional enterprise panels like cPanel/WHM and Plesk or lightweight modern panels like CyberPanel (OpenLiteSpeed) and CloudPanel, this playbook details automated SSL provisioning, PHP-FPM optimization, virtual host configuration, and server recovery procedures.
1. Web Control Panels Comparison
- cPanel & WHM: Industry standard for shared and reseller hosting with deep email (Exim/Dovecot) and MySQL management.
- CyberPanel: Built on OpenLiteSpeed for lightning-fast WordPress performance, native LSCache, and automated Let’s Encrypt certificates.
- CloudPanel: Minimalist PHP/Node.js/Python panel powered by Nginx and MySQL with ultra-low resource footprint.
- aaPanel: Modular web hosting control panel supporting one-click LAMP/LNMP environment deployment.
2. cPanel / WHM Service Troubleshooting
When web services fail to bind or Apache encounters syntax errors after vhost updates:
# Step 1: Check Apache configuration syntax
/usr/local/apache/bin/apachectl configtest
# Step 2: Gracefully restart Apache web daemon
/usr/local/cpanel/scripts/restartsrv_httpd
# Step 3: Rebuild user userdata vhost files
/scripts/rebuildhttpdconf
/scripts/updateuserdatacache --force3. CyberPanel & OpenLiteSpeed Tuning
# Restart OpenLiteSpeed server daemon
sudo systemctl restart lsws
# Check CyberPanel core service status
sudo systemctl status lscpd --no-pager
# Force renewal of expired SSL certificate for domain
/root/.acme.sh/acme.sh --renew -d linuxlab.art --force4. Automated Let’s Encrypt SSL with Certbot & Nginx
# Generate Wildcard SSL certificate using DNS verification
sudo certbot certonly --manual --preferred-challenges=dns \
-d "linuxlab.art" -d "*.linuxlab.art" \
--agree-tos --email admin@linuxlab.art
# Test automatic SSL certificate renewal dry-run
sudo certbot renew --dry-run
