chkconfig: command not found

The error message "chkconfig: command not found" indicates that the `chkconfig` command is not available on your system. `chkconfig` is a command-line tool used to manage services in some Linux distributions.

If you are using a distribution that does not include `chkconfig` by default, you might consider using an alternative service management tool like `systemctl` or `service`. These tools are commonly available in modern Linux distributions.

For example, to start a service using `systemctl`, you can use the following command:

sudo systemctl start <service-name>

Replace `<service-name>` with the actual name of the service you want to start.
