For this particular setup we will need 3 machines to act as kubernetes (k3s) masters and one machine to act as a datastore
The datastore will be a mysql (mariadb) server although you can choose different options
The operating system chosen for this task is Debian 11 (theoretically the setup can be performed on any linux machine)
Setup etcdctl using the instructions at https://github.com/etcd-io/etcd/releases/tag/v3.4.13 (changed path to /usr/local/bin):
Note: if you want to match th etcdctl binaries with the embedded k3s etcd version, please run the curl command for getting the version first and adjust ETCD_VER below accordingly:
curl -L --cacert /var/lib/rancher/k3s/server/tls/etcd/server-ca.crt --cert /var/lib/rancher/k3s/server/tls/etcd/server-client.crt --key /var/lib/rancher/k3s/server/tls/etcd/server-client.key https://127.0.0.1:2379/version

| the Dnf repoquery subcommand supports has a new option for listing all user-installed packages: | |
| $ dnf repoquery --qf '%{name}' --userinstalled \ | |
| | grep -v -- '-debuginfo$' \ | |
| | grep -v '^\(kernel-modules\|kernel\|kernel-core\|kernel-devel\)$' > pkgs_a.lst | |
| In contrast to other methods, it also lists all debuginfo packages. The additional grep in the above example filters them out. | |
| To install the list on host B: | |
| $ < pkgs_a.lst xargs dnf -y install |

The NGINX Unit control API includes a /status endpoint for usage statistics. This is a solution for exposing these metrics in Prometheus format.
The application (run by Unit) queries the /status URI on the control socket and converts the JSON response into Prometheus text format. PHP and Python implementations are available.
These instructions assume an existing Unit installation with a working configuration. We will add a new listener on the default prometheus port (9090) and route it directly to the Prometheus app.
Step 0. Install the preferred Unit language module (unit-php or unit-python)
