Our web company runs our entire hosting infrastructure on Clear Linux and we absolutely love it. Great work.
However, the need has arisen to install an older version of PHP on Clear Linux (7.2) alongside the current 7.3. We don’t want to disrupt 7.3 from being the default but want 7.2 accessible for only one NGINX site on a server hosting around 100 sites.
What’s the best way to achieve this and deploy 7.2 on a live production server, preferably without downtime?
