I am running nginx 1.2.6 on Ubuntu. With nginx, I can perform upgrades gracefully, so that no incoming requests will be lost.
Is there any process like that for PHP-FPM? If so, what is the process for doing the upgrade? Is it possible to ask PHP-FPM to reload
php.ini with no downtime?
If not, what's the next best way to perform the upgrade? Taking into account:
- that, we minimize downtime.
- Ensure that all current requests are performed and finished.
Note that our setup currently only consists of 1 server, with all services running on that machine.
