Prerequisites for Installing cPanel on CentOS 6

Step-by-Step Guide to Installing cPanel on CentOS 6

1. Prepare Your Environment

Ensure your server is updated and clean from residual configurations:

yum -y update yum -y clean all

2. Set the Hostname and Disable SELinux

Proper hostname configuration is critical:

hostnamectl set-hostname your.server.domain

Disabling SELinux (Security-Enhanced Linux) temporarily for installation:

setenforce 0 sed -i 's/^SELINUX=.*/SELINUX=permissive/' /etc/selinux/config

3. Install Required Dependencies

cPanel requires some essential packages:

yum -y install perl curl screen

4. Download the cPanel Installation Script

Navigate to a temporary directory and download the official cPanel installation script:

cd /home curl -o latest -L https://securedownloads.cpanel.net/latest

5. Launch the cPanel Installer

Start the installation process using the following command:

sh latest

Important: The installation can take 1-2 hours depending on server performance and network speed. Do not interrupt the process.

6. Post-Installation Configuration

  • Access the WebHost Manager (WHM) via https://your.server.ip:2087
  • Complete the setup wizard to configure basic settings, such as nameservers, IP addresses, and contact information.

Additional Tips for a Successful cPanel on CentOS 6 Installation

  • Firewall Settings: Configure firewalld or iptables to allow necessary ports like 2087, 2083, 80, 443, 22.
  • SSL Configuration: Enable SSL for secure data transmission, especially on public interfaces.
  • Automatic Updates: Enable cPanel auto-update feature to keep your server secure and up to date.
  • Backup Solutions: Implement daily backups using cPanel’s backup manager or third-party solutions to prevent data loss.
  • Monitoring & Security: Use cPanel’s monitoring features and frequently audit server logs for suspicious activity.

Common Challenges and Troubleshooting

Installation Failures

If the installation halts or throws errors, ensure that your server is up-to-date, has sufficient memory, and your hostname configuration is proper. Check logs located at /var/cpanel/logs for insights.

Networking Issues

Verify DNS records, firewall rules, and IP configurations. Ensuring ports are open and correctly routed is crucial for remote access.

Security Concerns

Post-installation, immediately configure security measures like firewalls, SELinux policies, and SSH key access to protect your server.
