The instructions do not make clear that in order for Redis to handle the job queue, mediawiki-services-jobrunner is required or else a critical error will occur:
Exception from line 92 of /var/www/html/w/includes/jobqueue/JobQueueRedis.php: Non-daemonized mode is no longer supported. Please install the mediawiki/services/jobrunner service and update $wgJobTypeConf as needed.
I have found the service required, but the instructions are not clear and installation is not intuitive for end-users. Puppet does not appear simple or necessary to install for most users, and it is not immediately obvious that the service is simply a script which needs to be perpetually run.
I am thinking I may be able to develop a solution by modifying the config available at https://github.com/wikimedia/mediawiki-services-jobrunner into a systemd service or init script by some other means.
Any ideas or support would be appreciated as Redis has been suggested as a more responsive cache system for use with some of Extension:Semantic MediaWiki's new features.
