Install Nextcloud on Rocky 9: SELinux, LDAP & Clustering

How to Install Nextcloud

4. 6. Download and Extract Nextcloud

   Get the latest Nextcloud release from the official site and extract it under your web root:

   cd /var/www/html && sudo curl -O https://download.nextcloud.com/server/releases/latest.tar.bz2 && sudo tar -xjf latest.tar.bz2 && sudo chown -R apache:apache nextcloud

5. 7. Configure Apache Virtual Host

   Create a new Apache configuration file for Nextcloud:

   sudo tee /etc/httpd/conf.d/nextcloud.conf <<'EOF'
   <VirtualHost *:80>
       ServerName nextcloud.example.com
       DocumentRoot /var/www/html/nextcloud
       <Directory /var/www/html/nextcloud>
           AllowOverride All
           Require all granted
       </Directory>
   </VirtualHost>
   EOF

6. 8. Adjust SELinux Contexts

   Apply proper SELinux permissions to allow Apache to write to Nextcloud’s directories:

   sudo semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/nextcloud(/.*)?' && sudo restorecon -Rv /var/www/html/nextcloud

7. 9. Allow HTTP/HTTPS Through Firewall

   Open the firewall ports for web access:

   sudo firewall-cmd --permanent --add-service=http && sudo firewall-cmd --permanent --add-service=https && sudo firewall-cmd --reload

8. 10. Enable HTTPS with Certbot

   Install Certbot and automatically configure HTTPS for Apache:

   sudo dnf install certbot python3-certbot-apache -y && sudo certbot --apache

9. 11. Configure PHP for Performance

   Tune PHP settings for better performance and clustering compatibility:

   sudo sed -i 's/memory_limit = .*/memory_limit = 512M/' /etc/php.ini && sudo systemctl restart php-fpm httpd

10. 12. Setup LDAP Authentication

    Enable enterprise-grade LDAP integration via the Nextcloud app (GUI) or command line:

    sudo -u apache php /var/www/html/nextcloud/occ app:enable user_ldap

11. 13. Enable Clustering Support

    For high availability, enable Redis caching and configure session locking:

    sudo dnf install redis php-redis -y && sudo systemctl enable --now redis && sudo -u apache php /var/www/html/nextcloud/occ config:system:set memcache.locking --value '\OC\Memcache\Redis'

12. 14. Optional: Configure NGINX Instead of Apache

    To use NGINX, disable Apache and install NGINX with a compatible PHP setup:

    sudo systemctl disable --now httpd && sudo dnf install nginx php-fpm -y && sudo systemctl enable --now nginx php-fpm

13. 15. Finalize Installation via Browser

    Open your browser at http://nextcloud.example.com and complete the web installer by entering your database credentials and admin user.
