Unattended installation of a poller

To install a poller quicker, you can use a script. This will perform all installation steps. You must then register the poller and attach it to the central server or the remote server.

Installation procedure

1. Update your system:

RHEL 8

dnf update
subscription-manager register --username my_username --password my_password --auto-attach --force
subscription-manager repos --enable codeready-builder-for-rhel-8-x86_64-rpms

Replace my_username and my_password with the credentials of your RedHat account.

Alma / Oracle Linux 8

dnf update

RHEL 9

dnf update
subscription-manager register --username my_username --password my_password --auto-attach --force
subscription-manager repos --enable codeready-builder-for-rhel-9-x86_64-rpms

Alma / Oracle Linux 9

dnf update

Debian 11

apt update && apt upgrade

2. Download the script using the following command:

curl -L https://download.centreon.com/22.10/unattended.sh --output /tmp/unattended.sh

3. Run the following command as root:

bash /tmp/unattended.sh install -t poller -v 22.10 -r stable -l DEBUG  2>&1 |tee -a /tmp/unattended-$(date +"%m-%d-%Y-%H%M%S").log

You will get a full log file with all errors in your tmp folder, named unattended(date).log.

4. Once the script has run, carry out steps 3 to 5 of the standard installation procedure for a poller.
