NextCloud

Prerequisites: 

• php 8.1 or php 8.2 or php 8.3

Used ISPConfig to provision an A record and website and database/database user / shell user, set the version of PHP to 8.1 , using php-fpm.

Almost verbatim to:

https://www.howtoforge.com/how-to-install-nextcloud-with-ispconfig/

Except comment out this line

;opcache.enable=1

Used the web installer

Issues after installation:

• sending emails from the web client

More setup:

opcache (enable opcache here)

; /etc/php/8.3/fpm/php.ini do the same for:
; /etc/php/8.1/fpm/php.ini
; opcache settings (reviewing these)
opcache.enable=1
opcache.enable_cli=1
opcache.memory_consumption=512
opcache.interned_strings_buffer=24
opcache.max_accelerated_files=299999
opcache.revalidate_freq=1
opcache.save_comments=1
opcache.jit_buffer_size=500000000
opcache.jit=1235

; Also put the same entry in /etc/php/8.3/cli/php.ini 
; Also put the same entry in /etc/php/8.1/cli/php.ini 

Restart php8.1-fpm (whichever version you're using)

Restart php8.3-fpm (whichever version you're using)

Restart redis-server (Oh ya I installed this also)

sudo apt install redis-server -y

service php8.1-fpm restart; service php8.3-fpm restart; service redis-server restart;

Nextcloud occ command (similar to artisan or drush):

make occ an executable

chmod 754 /path/to/nextcloud/occ

~/.bash_profile
PATH=/path/to/nextcloud/:$PATH
