Confused or stuck on the requirements?
If your current server or host can't meet the requirements, or you don't want to hassle with figuring things out, consider Cerb5 On-Demand. We'll handle the installation, hardware, upgrades, maintenance, performance tuning, troubleshooting, monitoring, local backups, twice weekly off-site backups to a redundant storage "cloud"; and we'll provide personal support by e-mail, chat, or phone.

Quick Start

  2. Extract the ZIP file into your website's filesystem.
  3. Set permissions (Linux, Mac OS X, BSD, Solaris):
    chown -R apache:apache *
    chmod -R 0774 storage/
  4. Copy the .htaccess-dist to .htaccess (Apache only)
  5. Create a database and user:
    mysql> CREATE DATABASE cerb5 CHARACTER SET utf8;
    mysql> GRANT ALL PRIVILEGES ON cerb5.* TO user@localhost IDENTIFIED BY 'password';
  6. Open http://www.example.com/cerb5/ in your browser and complete the guided installation process.
