I have server created based on Perfect Server tutorial. I am confused about few php.ini files. Inside /etc/php/7.0/ are directories like apache2, cgi, cli, fpm and mods-available. Inside first four is php.ini file. What's the difference between them? For example to change size of database imported by Phpmyadmin from default 2MB to something more I had to change values in php.ini from apache2 directory. Changes in another php.ini files don't do anything. Executing command php --ini gives result: Code: root@s1:~# php --ini Configuration File (php.ini) Path: /etc/php/7.0/cli Loaded Configuration File: /etc/php/7.0/cli/php.ini Scan for additional .ini files in: /etc/php/7.0/cli/conf.d Additional .ini files parsed: /etc/php/7.0/cli/conf.d/10-mysqlnd.ini, [...] so I thought /etc/php/7.0/cli/php.ini is default file and settings from him should work but it doesn't. I would like to use php-fpm for WordPress website set under ISP. If I would like to change some php settings for this website should I edit /etc/php/7.0/fpm/php.ini, yes? PS Is there any preferred php handler?
apache2: mod_php cgi: php-cgi and php-fcgi cli: commandline PHP fpm: php-fpm so the apache2 php.ini file was the correct one, but you have to restart apache afterwards. and you can't test it by using commandline php of course as commandline php iuses a different php.ini than mod_php. The recommended php handler for websites is php-fpm
Thank you till for answer. How could I determine that exactly for phpmyadmin changes I should change php.ini from apache2 directory?
Thank you for answer but where I am able to find this enigmatic howto? And what about, for example, some websites or mysql etc?
I was referring to the perfect ispconfig server howto. I don't know what examples you think of and in which context?
Thank you for answer. I thought that each software which uses php have some information about required php handler.
na, almost every phpscript ( no matter if u spent money big time or use wordpress + extensions ) works more or less as the following principle: try upgrading your php-version ; something stopped working? no error? try adding some common modules like -curl, -imap ..... still not working? oh well, go down a version and continue if it works again or fix the code yourself if its not encoded ^^ The software with accurate requirements beeing minimalistic and correct ... rare
Mhm, got it. Appreciate detailed answer. But I suppose there is some recommendations to use specific handler with specific software (easier or more complexity).
well there are some ( really old and horrific bad coded ) rare scripts out there needing mod_php or apache. setupwise: mod_php easiest, php-fpm mid, fastcgi complex and not beeing developed anymore anyway fcgi complex performancewise (throughput) mod_php, fastest php-fpm, depends on sockets/tcp-ip local or remote php-processes but still very fast fastcgi, fast fcgi, I don't know, but probably almost compareable to fastcgi resourcewise mod_php huge memory usage and loaded in each apache process, even if processing non-php content php-fpm, excellent - allows good fine-tuning + supports dynamic increase/decrease of php-processes based on load fastcgi pretty good fcgi uh well no figures on that really issue-wise mod_php causes issues with wrong file-permissions and general security, you would want to use some hacks like mpm_itk to isolate users, however mpm_itk is not best option to serve webs php-fpm, might want to chroot aswell, maybe need some fix if using sockets, depends on system but affects admins only and easy fix fastcgi can be a nightmare if you do it wrong fcgi same all non mod_php need additional configuration which wasnt documented very well until recent distro updates... missgin authorization headers and alike these are very basic and probably not fit for everyone thoughts.... I'd recommend apache2 mpm_worker, php-fpm if you have apache 2.4.34+ you could also try mpm_event if you use keepalive and want to trade some memory usage with cpu usage
