Unattended installation of a central server

To install a central server quicker, you can use a script. This will carry out the full installation procedure, including the web installation.

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 & 12

apt update && apt upgrade

2. Download the script using the following command:

curl -L https://raw.githubusercontent.com/centreon/centreon/24.04.x/centreon/unattended.sh --output /tmp/unattended.sh

3. Run the following command as root:

• To specify the password for the default admin account:

bash /tmp/unattended.sh install -t central -v 24.04 -r stable -s -p <admin_password> -l DEBUG  2>&1 |tee -a /tmp/unattended-$(date +"%m-%d-%Y-%H%M%S").log

• To get an autogenerated password for the default admin account (the script will tell you where the password is stored):

bash /tmp/unattended.sh install -t central -v 24.04 -r stable -s -l DEBUG  2>&1 |tee -a /tmp/unattended-$(date +"%m-%d-%Y-%H%M%S").log

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

Help

To get help on the script, use the following command:
