The other day our webhost (AWS to be specific) did a reboot due to hardware maintenance and one of our sites went down. It returned a 503 and after some time we figured out that the php71-php-fpm service wasn't running. Once started the site was up again (also some less crucial services like Grafana & Prometheus had to be started again). I now intend to make sure this doesn't happen again by enabling the service as its current setting is disabled. But...
...when checking the status for the service I find this this line quite puzzling:
Loaded: loaded (/usr/lib/systemd/system/php71-php-fpm.service; disabled; vendor preset: disabled)
- Would I create undesired side effects if I enabled the service?
I mean, there must (?) be a reason a service like this is disabled by default by the vendor. Or am I just being paranoid? :-)
