Install Nextcloud on an Ubuntu 20.04/22.04 server ★

This article details the complete deployment process for a Nextcloud server, from basic configuration to advanced optimization. First, it is necessary to modify `overwrite.cli.url` in `config.php` and set up Cron mode to automate background tasks. Second, it is recommended to install practical plugins such as two-factor authentication, task management, and notes. To expand storage capacity, create a new partition, format it, and mount a large-capacity hard drive, while ensuring that the data directory migration and permission settings are correctly configured. Additionally, the article covers region settings, preview feature optimization, and mail server configuration. It focuses on installing and configuring the Redis caching system, including APCu local caching and distributed lock settings, to resolve performance warnings and improve system efficiency. To prevent data loss, write an automated backup script to regularly sync the application directory, data files, and database to independent storage. Finally, a Caddy reverse proxy configuration solution is provided for specific needs, along with a guide for setting up a GPU acceleration environment if using the Recognize app, aiming to build a high-performance, secure, and easy-to-maintain private cloud environment.
