Rotating keys

For security reasons, the keys used to sign Centreon RPMs or the Debian repository must be rotated occasionally.

Fresh installation​

If you performed a fresh installation after the new RPM key was published, no additional actions are necessary, apart from accepting the new rpm key.

Retrieving key from https://yum-gpg.centreon.com/RPM-GPG-KEY-CES
Importing GPG key 0x3FC49C1B:
Userid     : "Centreon Enterprise Server Official Signing Key <admin@centreon.com>"
Fingerprint: 1035 e42c b766 7952 ee42 dee9 a97d aa5a 3fc4 9c1b
From       : https://yum-gpg.centreon.com/RPM-GPG-KEY-CES
Is this ok [y/N]:

However, you can check that you have the correct key.

Existing installation​

If you performed a fresh installation of a Centreon platform before the new RPM key was published, the existing key must be replaced with the new one.

  1. Download the following script:

    curl -JO https://raw.githubusercontent.com/centreon/centreon/master/centreon/check-centreon-gpg-key.sh

  2. Make the script executable:

    chmod u+x check-centreon-gpg-key.sh

  3. Run the script:

    sh check-centreon-gpg-key.sh

    The script will:

    • check the RPM key in the RPM database and ask you to remove it
    • check the key file in the /etc/pki/rpm-gpg directory
    • ask you to fetch and import the new RPM key into the RPM database
    • ask you to update the release RPM package (this will remove the revoked key from /etc/pki/rpm-gpg)
    • ask you to check the signature of the RPM packages.

Checks​

You can then check that the new key has been correctly imported. For the new key published on October 14, 2021:

  • After installation, check if the new key has been correctly imported into the RPM database:

    rpm -qi gpg-pubkey-3fc49c1b-651d4c25

    The results should be as follows:

    Name        : gpg-pubkey

    Release     : 651d4c25

  • Check that the only Centreon key in the RPM database is this one: gpg-pubkey-3fc49c1b-651d4c25:

    rpm -q gpg-pubkey --qf '%{NAME}-%{VERSION}-%{RELEASE}\t%{SUMMARY}\n'

    The results should be as follows:

    gpg-pubkey-f4a80eb5-53a7ff4b	gpg(CentOS-7 Key (CentOS 7 Official Signing Key) <security@centos.org>)
    gpg-pubkey-f2ee9d55-560cfc0a	gpg(CentOS SoftwareCollections SIG (https://wiki.centos.org/SpecialInterestGroup/SCLo) <security@centos.org>)
