Memory

^^^^^^
|
||||
|
||||
Memory requirements for running an Nextcloud server are greatly variable,
|
||||
depending on the numbers of users and files, and volume of server activity.
|
||||
Nextcloud needs a minimum of 128MB RAM, and we recommend a minimum of 512MB.
|
||||
depending on the numbers of users, apps, files and volume of server activity.
|
||||
|
||||

Database requirements for MySQL / MariaDB
|
||||
-----------------------------------------
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
The following is currently required if you're running Nextcloud together with a MySQL / MariaDB database:
|
||||
|
||||
* InnoDB storage engine (MyISAM is not supported)
|
||||
* "READ COMMITED" transaction isolation level (See: :ref:`db-transaction-label`)
|
||||
* Disabled or BINLOG_FORMAT = ROW configured Binary Logging (See: https://dev.mysql.com/doc/refman/5.7/en/binary-log-formats.html)
|
||||
* For **Emoji (UTF8 4-byte) support** see :doc:`../configuration_database/mysql_4byte_support`
|
||||
|
||||
Emoji (UTF8 4-byte) support with MySQL / MariaDB
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
Desktop client
|
||||
--------------
|
||||
|
||||
If you want to use UTF8 4-byte characters such as Emojis on your server, the database needs to be created with character set ``utf8mb4`` and collate ``utf8mb4_general_ci``, e.g.::
|
||||
We strongly recommend using the latest version of your operating system to get the full and most stable experience out
|
||||
of our clients.
|
||||
|
||||
CREATE DATABASE nextcloud CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
|
||||
* **Windows** 7+
|
||||
* **macOS** Lion (10.7)+ (64-bit only)
|
||||
* **Linux** (CentOS 6.5+, Ubuntu 14.04+, Fedora 21+, openSUSE 13, SUSE Linux Enterprise 11 SP3+, Debian 8 (Jessie)+, Red Hat
|
||||
Enterprise Linux 7)
|
||||
|
||||
Additionally the following InnoDB settings need to be set::
|
||||
Mobile apps
|
||||
-----------
|
||||
|
||||
[mysqld]
|
||||
innodb_large_prefix=on
|
||||
innodb_file_format=barracuda
|
||||
innodb_file_per_table=true
|
||||
We strongly recommend using the latest version of your mobile operating system to get the full and most stable experience out
|
||||
of our mobile apps.
|
||||
|
||||
See :doc:`../configuration_database/mysql_4byte_support` for more information.
|
||||
- **iOS** 9.x+
|
||||
- **Android** 4.x+
|
||||
|
||||
.. note:: The separate Nextcloud Talk app requires iOS 9.x+ or Android 5.x+.
|
||||
|
||||
Webbrowser
|
||||
----------
|
||||
|
||||
For best experience with the Nextcloud webinterface, we recommend you to use the latest and supported version of a browser from this list, or one based on those:
|
||||
|
||||
- Microsoft **Internet Explorer 11** (latest version)
|
||||
- Microsoft **Edge**
|
||||
- Mozilla **Firefox**
|
||||
- Google **Chrome**/Chromium
|
||||

|
||||
|
||||
.. note:: If you want to use Nextcloud Talk you should use Mozilla **Firefox** 52+ or Google **Chrome**/Chromium 49+ to have
|
||||
the full experience with video calls and screensharing. Google Chrome/Chromium requires a additional plugin for
|
||||
screensharing.
