The tutorial addresses the cPanel curl not found issue caused by missing hostnames and nameservers. It provides a step-by-step guide to set up the hostname, update the /etc/hosts file, configure nameservers, restart the networking service, and verify changes.

1. Open Terminal or SSH into your server:
   Use your preferred terminal or SSH client to connect to your server.
2. Set the Hostname:
   Run the following command to set the hostname:

   hostnamectl set-hostname yourhostname.example.com

Replace “yourhostname.example.com” with your desired hostname.

3. Update the /etc/hosts file:
   Open the /etc/hosts file using a text editor:

   nano /etc/hosts

Add the following line:

   your_server_ip yourhostname.example.com

Save and exit.

4. Update Nameservers:
   Edit the /etc/resolv.conf file:

   nano /etc/resolv.conf

Add your nameservers:

   nameserver 8.8.8.8
   nameserver 8.8.4.4

Replace these with your preferred nameservers. Save and exit.

5. Restart Networking Service:
   Restart the networking service to apply changes:

   systemctl restart network

6. Verify Changes:
   Check if the hostname is set correctly:

   hostname

It should display your chosen hostname.

7. Verify Curl:
   Test if curl is now working:

   curl http://google.com

Replace “google.com” with any valid URL. If the curl is working, you’ve resolved the issue.
