If you want to run modern, high-performance applications alongside your Nextcloud—like AI backends or real-time collaborative tools—you’ll be dealing with the AppAPI and . However, the old ways of connecting Nextcloud to ExApps came with significant performance bottlenecks and configuration headaches. This is where HaRP changes everything.
This appears to be a known behavior where HaRP's internal state is not fully restored after a system reboot. The current workaround is to add a systemd service or cron job that automatically restarts the HaRP container after reboot, or to manually restart it with docker restart appapi-harp .
File ownership mismatch during deployment. Fix: Run this on the server:
One of HaRP's most powerful features is the ability to run on a separate machine from your Nextcloud instance. This is particularly useful if you have a dedicated server with specialized hardware (like a powerful GPU for AI workloads) that you want to use for ExApps while keeping Nextcloud on another machine. harp nextcloud install
: You will need to define a HP_SHARED_KEY (e.g., a long random string) in your environment variables. This key must match what you enter later in the Nextcloud UI. 2. Configure Your Main Reverse Proxy
sudo apt install -y php-fpm php-mysql php-common php-curl php-gd php-intl php-mbstring php-xml php-zip php-bcmath php-gmp php-imagick php-opcache php-cli Use code with caution. Optimize PHP Settings
objectStore: enabled: true type: s3 s3: bucket: nextcloud-data region: us-east-1 endpoint: https://minio.example.com accessKey: "minioadmin" secretKey: "minioadmin123" If you want to run modern, high-performance applications
Here's a conceptual example, which you would need to adapt to your specific reverse proxy software.
Nextcloud requires a robust relational database to store file metadata, user accounts, and system configurations. MariaDB runs exceptionally well on ARM64 platforms. Install the MariaDB server package: sudo apt install -y mariadb-server Use code with caution.
Install Apache along with the required PHP 8.x modules for Nextcloud: This appears to be a known behavior where
Additionally, append the allowed application server IP addresses to /etc/postgresql/16/main/pg_hba.conf : host nextcloud_db nextcloud 192.168.1.0/24 scram-sha-256 Use code with caution. Restart the service to apply changes: sudo systemctl restart postgresql Use code with caution. Step 2: Install and Configure Redis (The "R")
Locate and modify the following directives to match these production recommendations:
