Access to the PHP71 preview branch?

Fresh install of 123.08stable and 123.09beta01 instructions are both on official install page at https://centminmod.com/install.html

If you are switching from 123.08stable existing install to upgrade to 123.09beta01, then below instructions

Upgrading Centmin Mod Code to Latest Version

Getting Started Guide step 19 outlines also how to keep Centmin Mod code updated or how to switch version branches or you can run cmupdate command that was recently added.

Centmin Mod LEMP stack's script code is constantly updated for improvements, bug fixes and security fixes so keeping the Centmin Mod code up to date is important. With Centmin Mod 1.2.3-eva2000.08) (123.08stable) and higher releases, a newly added centmin.sh menu option 23 allows much easier code updates and version branch switching via Git backed environment you can setup.

For 123.08stable that means centmin.sh menu option 23 submenu option 2 (if you previously ran submenu option 1) first, then exit centmin.sh, re-enter /usr/local/src/centminmod and re-run centmin.sh menu.

For 123.09beta01 and higher that means running SSH command = cmupdate and then re-enter /usr/local/src/centminmod and re-run centmin.sh menu.

Example of using 123.09beta01 cmupdate command to update Centmin Mod code on your server

Upgrading Centmin Mod involves 2 parts.

1. Upgrading the actual Centmin Mod code outlined at Upgrade Centmin Mod. This is heart of Centmin Mod where the code is the engine that runs centmin.sh shell based menu and all the automation you're accustomed to. You can easily update within a Centmin Mod version branch or switch version branches via centmin.sh menu option 23 outlined here.
2. Upgrade software that Centmin Mod installed or manages. For this part following outline at How to upgrade Centmin Mod software installed on your server.

So essentially, you can upgrade from one version branch to another i.e. 123.08stable to 123.09beta01 or higher in place, but not everything is upgraded as some things like server initial environment setup isn't changed i.e. how swap, tmp setup and allocation are created etc. The main parts from part 2 above are what in place upgrades do i.e. Nginx and PHP-FPM compilation and config/settings parameters and MariaDB version from 5.5 to 10.0.x. If you want the full environment changed including tmp and swap setup to 123.09beta01 etc configuration, then you would need a fresh OS install and fresh 123.09beta01 initial install. You can think of it like upgrading Windows 7 to Windows 8. An in place upgrade will upgrade code but won't change your computer environment from when you installed Windows 7 i.e. disk configuration and partition sizes won't change from when you initially installed Windows 7. Only way to change that would be fresh Windows 8 install.

 

Not right now, only one version of PHP supported still. If you're referring to multiple PHP version preview support at https://community.centminmod.com/th...multiple-php-fpm-versions-work-preview.11900/, that isn't ready for production use yet and still in internal private testing.

 

Yeah it would out of box but you'd need to know how to reconfigure Remi PHP 7 so that it doesn't interfere. The easiest thing to do is do upgrade on separate VPS server with PHP 7 - just spin up an hourly billed VPS from Upcloud, Linode, DigitalOcean or Vultr for the upgrade itself by making copy of existing forum on the separate VPS server. That's how I usually do it as I never touch the live server files/database for upgrades, always only do upgrades on a copy of the live data/files.
