System Requirements
Make sure that you complete the following tasks before you start the installation process:
1. Setup Hostname
This hostname cannot be the same as any domain that is on your server (for example, if example.com is a domain on your server, use hostname.example.com as your fully qualified hostname).
You can use the following command for hostname setup eg. srv1.example.com
hostname srv1.example.com
2. Setup Server IP addresses
Define additional IP address, subnet address, and default gateway IP address for your server — your service provider can provide you with this information.
3. Software Requirements
You must have a clean/fresh installation of supported operating systems:
- CentOS 7 MINIMAL is recommended version. (RECOMMENDED STABLE)
The best version to be used with CWP as it provides the most features and CWP Secure Kernel.
- CWP-CentOS 8 MINIMAL or BOOT Stream-Delayed. (RECOMMENDED LATEST)
We have our custom repositories making CentOS 8 Stream a stable version. More Info
- CentOS 8 Stream MINIMAL or BOOT
Direct installation or converted from CentOS 8 Linux. (Recommended)

4. Hardware Requirements
64 bit operating systems require a MINIMUM of 2GB RAM.
Recommended System: 4 GB+ RAM so you would have the full functionality such as Anti-virus scan of emails.
5. Preparing Server
Let’s install required packages for CWP installation
yum -y install wget
CentOS 8, Alma Linux and Rocky Linux: may need to install the EPEL repository to be able to install tools like wget:
yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm dnf install wget -y
6. Server Update
Now we need to update your server to the latest version
yum -y update
7. Reboot Server
Reboot your server so that all updates can take effect.
reboot
Now you are ready to start CWP Installation
CWP installer can run more than 30 minutes because it needs to compile apache and php from source.
