Requirements

Cells ships as a set of precompiled static binaries, one for each operating system. The only required dependency is a MySQL database.

Hardware/OS

• CPU: AMD 64bit architecture only, 2 core or more are recommended.
• RAM: 4GB RAM
• Disk: SSD is highly recommended for storage.
• Supported OS:
  • Debian Like: Debian 10 (Buster) LTS, Debian 9 (Stretch) LTS / Raspbian Stretch, Debian 8 (Jessie) LTS / Raspbian Jessie, Ubuntu 20.04 (Focal Fossa), Ubuntu 18.04 (Bionic Beaver), Ubuntu 16.04 (Xenial Xerus)
  • RHEL: RHEL7, CentOS7, RHEL6, CentOS 6
  • MacOSX: 10.13/11.1
  • Windows: 10 (Cells Home only)

Important Settings

• Dedicated OS user: never run Cells as "root" user!
• Ulimit: the number of allowed open files must be greater than 2048. For production use, a minimum of 8192 is recommended (see ulimit -n).

MySQL/Maria DB versions

Supported server versions:

• MariaDB version 10.3 and above
• MySQL version 5.7 and above (except 8.0.22 that has a bug preventing cells to run correctly)

Creating a database and a privileged user

CREATE USER 'pydio'@'localhost' IDENTIFIED BY '<your-password-here>';
CREATE DATABASE cells DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_bin;
GRANT ALL PRIVILEGES ON cells.* to 'pydio'@'localhost';
FLUSH PRIVILEGES;

Important Settings

Always ensure that the database is created with character set and collation set to UTF8.

Make sure not to leave the max_connections to its default value (151) for production we advise at least 500, for a better understanding see MySQL manual.

Network requirements

Gateway

Cells provides its own webserver as a unified Gateway to public-facing services. As such, unlike old versions of Pydio, you do not need Apache or equivalent.

The Gateway will "bind" to a TCP Port like a standard web server. The port number used is defined in the ./cells configure sites command, or directly as a parameter of the start command in the command line interface.

This is the port that need to be opened in your firewall to make Cells accessible outside the server.

Services

Cells uses TCP/IP connections to communicate between services. Most of the services use random available ports. The following are using pre-defined ports, that can be overridden in all commands that refer to services in the command line interface (eg start, admin, ...)
