CENTOS WEB PANEL – 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 6, RedHat 6 or CloudLinux 6, MINIMAL installation and English version only!
• CentOS 7 is NOT supported.

4. Hardware Requirements

• 32 bit operating systems require a minimum of 512 MB RAM
• 64 bit operating systems require a minimum of 1024 MB RAM (recommended)
• Recommended System: 4 GB+ RAM so you would have the full functionality such as Anti-virus scan of emails.

How TO Setup Remote Backup CWP

ssh remote key authentication

Instructions for adding ssh pub key on the remote backup server.
Replace the USERNAME with the existing username on the remote server, it’s not recommended to use the root user.

This instructions are only for the backups on the remote server.
To Enable remote backup in your CWP.admin go to CWP Settings –> Backup Configuration

You will need to enter the login details into the fields of “Remote Backup Settings”
Don’t forget to generate the new remote access Key.

On the remote backup server you need to add the pub key
cd ~USERNAME
mkdir .ssh
chmod 700 .ssh
nano .ssh/authorized_keys
Now add all content from the file /root/.ssh/backup/id_rsa.pub to .ssh/authorized_keys
chmod 600 .ssh/authorized_keys
chown -R USERNAME:USERNAME .ssh
chown USERNAME:USERNAME .ssh/authorized_keys

You can use test connection button in CWP.admin to check connectivity with the remote backup server.

To connect and check content on the backup server you can use ssh key access:

ssh USERNAME@SERVER-IP -i /root/.ssh/backup/id_rsa
