Spoiler: my question should be irrelevant with this info Please fill in any relevant information that applies to you: CentOS Version: CentOS 7 64bit Centmin Mod Version Installed: 123.09beta01 Nginx Version Installed: 1.11.8 (on ma way to 1.11.9) PHP Version Installed: 7.1.1 MariaDB MySQL Version Installed: 10.1.20 When was last time updated Centmin Mod code base ? : i dunno, there was a cronjob for it, and centmin said that it was up to date when i logged in, so~~ I think someone might have asked about this before, but I couldn't think up the right phrases for the keywords. So yeah, my question is on the title. As we know, if we want to enable ngx_pagespeed, we'll have to write NGINX_PAGESPEED=y in custom_config.inc (update me if my knowledge is already outdated) and then, I can't remember if it's a "must" or not, we also have to write NGXPGSPEED_VER and NGINX_PAGESPEEDPSOL_VER with the desired version (with '-beta' on the former). What if I want to just remain 'up-to-date' with the latest version whenever I rebuild my NGINX though? Can't I just remove NGXPGSPEED_VER and NGINX_PAGESPEEDPSOL_VER so that Centmin Mod will automatically choose the latest version available if I have NGINX_PAGESPEED=y? (experimenting this sounds risky for some reason, so I haven't tried - there should be many failsafes in Centmin Mod though, so I don't know what I'm afraid of) Thanks in advance btw!
