How to solve the problem

Solution Centos/RedHat
 

• Check permissions:

ll /etc/centreon-engine/

ll /etc/centreon-broker/

• As you can see apache isn’t the owner

Here is the commands to solve:

chown apache:apache /etc/centreon-engine/*

chown apache:apache /etc/centreon-broker/*

su - apache -s /bin/bash -c umask

• If the issue isn’t solved, check the permissions here:

ll -R /var/cache/centreon/config/

ll -R /var/cache/centreon/symfony

Apache should be the owner aswell.
