As of MISP version 2.4.151 we introduced a simpler way to handle background jobs without relying in CakeResque as this library is no longer mantained.
For the time being both background jobs backends will be supported, but we plan to phase out the CakeResque one in a near future.
The new backend requires Supervisor and some extra PHP packages.
This guide is intended for RHEL systems (tested on RHEL8)
