Install ownCloud on Rocky Linux 9: SELinux, LDAP & Clustering

How to Install ownCloud

6. 6. Download and Extract ownCloud

   Get the latest ownCloud release from the official repository and extract it into your web root:

   cd /var/www/html && sudo curl -O https://download.owncloud.org/community/owncloud-complete-latest.tar.bz2 && sudo tar -xjf owncloud-complete-latest.tar.bz2 && sudo chown -R apache:apache owncloud

7. 7. Configure Apache Virtual Host

   Create a new Apache configuration file for ownCloud:

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

8. 8. Adjust SELinux Contexts

   Apply proper SELinux permissions so Apache can write to ownCloud’s directories:

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

9. 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

10. 10. Enable HTTPS with Certbot

    Install Certbot and automatically configure HTTPS for Apache:

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

11. 11. Configure PHP for Performance

    Optimize PHP settings for better performance and high availability:

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

12. 12. Setup LDAP Authentication

    Enable enterprise-level LDAP integration from the ownCloud app settings or CLI:

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

13. 13. Enable Clustering Support

    Set up Redis caching for locking and session management in clustered environments:

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

14. 14. Optional: Configure NGINX Instead of Apache

    To use NGINX, disable Apache and install NGINX with compatible PHP-FPM configuration:

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

15. 15. Finalize Installation via Browser

    Open your browser at http://owncloud.example.com and complete the web setup wizard by entering database credentials and admin account details.
