Many times on this forum it is said do that and that and recompile then. Example is recompile php with option 5 in centmin menu, after update some php extension. So, when I choose option 5 (Upgrade/downgrade PHP), what exactly to choose in menu after that if I'm allready on newest version of PHP
See step 2 of below guide, most of the time to recompile, you just enter the same version number of your existing Nginx or PHP version. Upgrading Centmin Mod Code to Latest Version Upgrading Centmin Mod involves 2 parts. Upgrading the actual Centmin Mod code outlined at Upgrade Centmin Mod - CentminMod.com LEMP Nginx web stack for CentOS 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. Upgrade software that Centmin Mod installed or manages. For this part following outline at Upgrade - How to upgrade Centmin Mod | Centmin Mod Community So essentially, you can upgrade from .07 to .08 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 .08's configuration, then you would need a fresh OS install and fresh .08 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.
So basically update to same version I have installed? So when advice is recompile php/nginx I should choose upgrade php or nginx and set same version when asked me to which version I should to upgrade?
