Steps

Cloudflare

(Optional) Opnsense: Create virtual IP for HA Proxy (Entry point)

2. HAProxy: Redirect to inernal Nextcloud Server

3. Unbound DNS: Local DNS entry for reverse proxying to nextcloud

PHP OPcache buffer

Error from Nextcloud The OPcache buffer is nearly full. To assure that all scripts can be hold in cache, it is recommended to apply opcache.memory_consumption to your PHP configuration with a value higher than 256. PHP Documentation Nextcloud Documentation

/etc/php/8.2/fpm/php.ini

vi /etc/php/8.2/fpm/php.ini

...
; The OPcache shared memory storage size.
opcache.memory_consumption=512
...

systemctl restart php8.2-fpm.service

Troubleshooting PHP-fpm

• Good Guide Source
• Helps determine how to calculate the FPM parameters.FPM Calculator ATTENTION! please remind yourself, that you need to reserve memory for DB, Redis, OPcache and the System!
• Nextcloud Docu

vi /etc/php/8.2/fpm/pool.d/www.conf

#Edit the following lines according to the previously mentioned FPM Calculator
pm.max_children = 220
pm.start_servers = 55
pm.min_spare_servers = 55
pm.max_spare_servers = 165

Troubleshooting PHP

; Maximum amount of memory a script may consume
; https://php.net/memory-limit
memory_limit = 14G

Migration

How to migrate to a new Nextcloud instance (no HA). Mostly needed because of security reasons. See Nextcloud Migration and Nextcloud Backup documentation.

Steps

1. Set up ne Nextcloud instance
2. Enable Maintenance mode on current Nextcloud instance
3. Create a dump of the database and copy it to the new instance
4. Copy all files with rsync

rsync -Aavx /data_nvme/ root@192.168.3.110:/data/

1. Check the "old" system for a data-fingerprint
2. Make some checks with a client that you changed the hosts file
3. Release your new Nextcloud instance!
