Perform a backup​

Be sure that you have fully backed up your environment for the following servers:

Update the RPM signing key​

For security reasons, the keys used to sign Centreon RPMs are rotated regularly. The last change occurred on October 14, 2021. When upgrading from an older version, you need to go through the key rotation procedure, to remove the old key and install the new one.

Run the following commands:

yum install -y https://yum.centreon.com/standard/20.10/el7/stable/noarch/RPMS/centreon-release-20.10-4.el7.centos.noarch.rpm

If you are using a CentOS environment, you must install the Software Collections repositories with the following command:

yum install -y centos-release-scl-rh

Clean yum cache:

yum clean all --enablerepo=*
