Install Knot

1. Connect to the server (nsX.lab.nxdomain.se) by using SSH or PuTTY.

2. Change the host name:

   hostnamectl set-hostname nsX.lab.nxdomain.se
   

3. Logout and login to get an updated command prompt.

4. Upgrade base operating system:

   dnf upgrade
   

5. On RedHat, CentOS and Rocky, install EPEL:

   dnf install epel-release
   

   Not needed here since we're using Fedora Linux.

6. Enable Knot repostory:

   dnf install 'dnf-command(copr)'
   dnf copr enable @cznic/knot-dns-latest
   

7. Install Knot. Also install bind-utils for dig(1):

   dnf install knot knot-utils bind-utils
   

8. Ensure that Knot has a reasonable default configuration:

   vi /etc/knot/knot.conf
   

   Add:

   server:
       rundir: "/run/knot"
       user: knot:knot
       listen: [ 0.0.0.0@53, ::@53 ]
   
   log:
     - target: syslog
       any: info
   
   database:
       storage: "/var/lib/knot"
   
   acl:
     - id: acl_localhost
       address: 127.0.0.1
       action: transfer
   
   template:
     - id: default
       storage: "/var/lib/knot"
       file: "%s.zone"
   

9. Check that the configuration is valid:

   knotc conf-check
   

10. Disable systemd-resolved(8) as it might interfer with Knot:

    systemctl disable systemd-resolved
    systemctl stop systemd-resolved
    

11. Enable and start Knot:

    systemctl enable knot
    systemctl start knot
