# ownCloud 9.0 Server Administration Manual

# Preferred Linux Installation Method

## Installation Quick Start

See the System Requirements for the recommended ownCloud setup and supported platforms.

Installing ownCloud Server (the free community edition) on Linux from our Open Build Service packages is the preferred method. These are maintained by ownCloud engineers, and you can use your package manager to keep your ownCloud server up-to-date. Follow the instructions for your distro to add the ownCloud Open Build Service repository, download and install the repository signing key, and install ownCloud. Then run the Installation Wizard to complete your installation. (see Installation Wizard).

Note

Do not move the folders provided by these packages after the installation, as this will break updates.

## Installing ownCloud Enterprise Subscription

See Installing & Upgrading ownCloud Enterprise Subscription for instructions on installing ownCloud Enterprise Subscription.

## Downgrading Not Supported

Downgrading is not supported and risks corrupting your data! If you want to revert to an older ownCloud version, install it from scratch and then restore your data from backup. Before doing this, file a support ticket (if you have paid support) or ask for help in the ownCloud forums to see if your issue can be resolved without downgrading.

## Additional Installation Guides and Notes

See Installation Wizard for important steps such as choosing the best database and setting correct directory permissions.

See SELinux Configuration for a suggested configuration for SELinux-enabled distributions such as Fedora and CentOS.

If your distribution is not listed, your Linux distribution may maintain its own ownCloud packages, or you may prefer to install from source code (see Manual Installation on Linux).

Archlinux: The current stable version is in the official community repository, and more packages are in the Arch User Repository.

Mageia: The Mageia Wiki has a good page on installing ownCloud from the Mageia software repository.

Debian/Ubuntu: The package installs an additional Apache config file to `/etc/apache2/conf-available/owncloud.conf` which contains an `Alias` to the owncloud installation directory as well as some more needed configuration options.

Running ownCloud in a subdir: If you’re running ownCloud in a subdir and want to use CalDAV or CardDAV clients make sure you have configured the correct Service discovery URLs.

Note for MySQL/MariaDB environments: Please refer to MySQL / MariaDB with Binary Logging Enabled on how to correctly configure your environment if you have binary logging enabled.
