System Requirements¶

Officially Recommended & Supported Options¶

For best performance, stability, support, and full functionality we officially recommend and support:

Server¶

Platform	Options
Operating System	Ubuntu 16.04, 17.04 and 17.10; Debian 7, 8 and 9; SUSE Linux Enterprise Server 12 with SP1, SP2 and SP3; Red Hat Enterprise Linux/Centos 6.9, 7.3 and 7.4; Fedora 26, 27 and 28; open Suse Tumbleweed and Leap 42.1, 42.2, 42.3

PHP Runtime	PHP (5.6+, 7.0, & 7.1)

Important

For the future release of ownCloud 10.1, a minimum php version of 7.1 is needed. If you use Ubuntu 16.04:

PHP 7.1 is only available via ppa. To add a ppa to your system, use this command: sudo add-apt-repository ppa:user/ppa-name.
PHP 7.2 standard installable, but you have to install some mandatory modules yourself, like intl.

Note

Red Hat Enterprise Linux & Centos 7 are 64-bit only.
Oracle 11g is only supported for the Enterprise edition.
SQLite is not encouraged for production use.

Mobile¶

iOS 9.0+
Android 4.0+

Web Browser¶

Edge (current version on Windows 10)
IE11+ (except Compatibility Mode)
Firefox 57+ or 52 ESR
Chrome 64+
Safari 10+

Hypervisors¶

Hyper-V
VMware ESX
Xen
KVM

Desktop¶

Windows 7+
Mac OS X 10.7+ (64-bit only)
CentOS 6 & 7 (64-bit only)
Debian 7.0 & 8.0 & 9.0
Fedora 26 & 27
Ubuntu 16.04 & 17.04 & 17.10
openSUSE Leap 42.2 & 42.3

Note

For Linux distributions, we support, if technically feasible, the latest 2 versions per platform and the previous LTS.

Alternative (But Unsupported) Options¶

If you are not able to use one or more of the above tools, the following options are also available.

Web Server¶

NGINX with PHP-FPM

Memory Requirements¶

Memory requirements for running an ownCloud server are greatly variable, depending on the numbers of users and files, and volume of server activity. ownCloud officially requires a minimum of 128MB RAM. But, we recommend a minimum of 512MB.

Note

Consideration for low memory environments

Scanning of files is committed internally in 10k files chunks. Based on tests, server memory usage for scanning greater than 10k files uses about 75MB of additional memory.

Database Requirements¶

The following are currently required if you’re running ownCloud together with a MySQL or MariaDB database:

Disabled or BINLOG_FORMAT = MIXED or BINLOG_FORMAT = ROW configured Binary Logging (See: MySQL / MariaDB with Binary Logging Enabled)
InnoDB storage engine (The MyISAM storage engine is not supported, see: MySQL / MariaDB storage engine)
“READ COMMITED” transaction isolation level (See: MySQL / MariaDB “READ COMMITED” transaction isolation level)
