ownCloud Server Administration Manual
Installing ownCloud on Linux from our Open Build Service packages is the preferred method (see Preferred Linux Installation Method). These are maintained by ownCloud engineers, and you can use your package manager to keep your ownCloud server up-to-date.
If there are no packages for your Linux distribution, or you prefer installing from the source tarball, you can setup ownCloud from scratch using a classic LAMP stack (Linux, Apache, MySQL/MariaDB, PHP). This document provides a complete walk-through for installing ownCloud on Ubuntu LTS Server with Apache and MariaDB, using the ownCloud .tar archive.
Note
Admins of SELinux-enabled distributions such as CentOS, Fedora, and Red Hat Enterprise Linux may need to set new rules to enable installing ownCloud. See SELinux Configuration Tips for a suggested configuration.
Prerequisites¶
The ownCloud .tar archive contains all of the required PHP modules. This section lists all required and optional PHP modules. Consult the PHP manual for more information on modules. Your Linux distribution should have packages for all required modules. You can check the presence of a module by typing . If you get a result, the module is present.
Required:
- php5 (>= )
- PHP module ctype
- PHP module dom
- PHP module GD
- PHP module iconv
- PHP module JSON
- PHP module libxml (Linux package libxml2 must be >=)
- PHP module mb multibyte
- PHP module posix
- PHP module SimpleXML
- PHP module XMLWriter
- PHP module zip
- PHP module zlib
Database connectors (pick the one for your database:)
- PHP module sqlite (>= 3, usually not recommended for performance reasons)
- PHP module pdo_mysql (MySQL/MariaDB)
- PHP module pgsql (requires PostgreSQL >= )
Recommended packages:
- PHP module curl (highly recommended, some functionality, e.g. HTTP user authentication, depends on this)
- PHP module fileinfo (highly recommended, enhances file analysis performance)
- PHP module bz2 (recommended, required for extraction of apps)
- PHP module intl (increases language translation performance and fixes sorting of non-ASCII characters)
- PHP module mcrypt (increases file encryption performance)
- PHP module openssl (required for accessing HTTPS resources)
Required for specific apps:
- PHP module ldap (for LDAP integration)
- PHP module ftp (for FTP storage / external user authentication)
- PHP module imap (for external user authentication)
- PHP module smbclient (SMB/CIFS integration)
Note
SMB/Windows Network Drive mounts require the PHP module smbclient; see SMB/CIFS.
Recommended for specific apps (optional):
- PHP module exif (for image rotation in pictures app)
- PHP module gmp (for SFTP storage)
For enhanced server performance (optional) select one of the following memcaches:
- PHP module apc
- PHP module apcu
- PHP module memcached
- PHP module redis (>= +, required for Transactional File Locking)
See Configuring Memory Caching to learn how to select and configure a memcache.
For preview generation (optional):
- PHP module imagick
- avconv or ffmpeg
- OpenOffice or LibreOffice
For command line processing (optional):
- PHP module pcntl (enables command interruption by pressing )
You don’t need the WebDAV module for your Web server (i.e. Apache’s ), as ownCloud has a built-in WebDAV server of its own, SabreDAV. If is enabled you must disable it for ownCloud. (See Apache Web Server Configuration for an example configuration.)
MySQL/MariaDB Require InnoDB¶
The InnoDB storage engine is required, and MyISAM is not supported, see: db-storage-engine-label.
Example Installation on Ubuntu LTS Server¶
On a machine running a pristine Ubuntu LTS server, install the required and recommended modules for a typical ownCloud installation, using Apache and MariaDB, by issuing the following commands in a terminal:
- This installs the packages for the ownCloud core system. provides the following PHP extensions: . If you are planning on running additional apps, keep in mind that they might require additional packages. See Prerequisites for details.
- At the installation of the MySQL/MariaDB server, you will be prompted to create a root password. Be sure to remember your password as you will need it during ownCloud database setup.
Now download the archive of the latest ownCloud version:
Go to the ownCloud Download Page.
Go to Download ownCloud Server > Download > Archive file for server owners and download either the www.cronistalascolonias.com.ar2 or .zip archive.
This downloads a file named www.cronistalascolonias.com.ar2 or www.cronistalascolonias.com.ar (where x.y.z is the version number).
Download its corresponding checksum file, e.g. www.cronistalascolonias.com.ar5, or www.cronistalascolonias.com.ar
Verify the MD5 or SHA sum:
md5sum -c www.cronistalascolonias.com.ar5 < www.cronistalascolonias.com.ar2 shasum -c www.cronistalascolonias.com.ar < www.cronistalascolonias.com.ar2 md5sum -c www.cronistalascolonias.com.ar5 < www.cronistalascolonias.com.ar shasum -c www.cronistalascolonias.com.ar < www.cronistalascolonias.com.arYou may also verify the PGP signature:
wget www.cronistalascolonias.com.ar wget www.cronistalascolonias.com.ar gpg --import www.cronistalascolonias.com.ar gpg --verify www.cronistalascolonias.com.ar www.cronistalascolonias.com.ar2Now you can extract the archive contents. Run the appropriate unpacking command for your archive type:
tar -xjf www.cronistalascolonias.com.ar2 unzip www.cronistalascolonias.com.arThis unpacks to a single directory. Copy the ownCloud directory to its final destination. When you are running the Apache HTTP server you may safely install ownCloud in your Apache document root:
cp -r owncloud /path/to/webserver/document-rootwhere is replaced by the document root of your Web server:
On other HTTP servers it is recommended to install ownCloud outside of the document root.
BINLOG_FORMAT = STATEMENT¶
If your ownCloud installation fails and you see this in your ownCloud log:
See MySQL / MariaDB with Binary Logging Enabled.
Apache Web Server Configuration¶
On Debian, Ubuntu, and their derivatives, Apache installs with a useful configuration so all you have to do is create a file with these lines in it, replacing the Directory and other filepaths with your own filepaths:
Then create a symlink to :
Additional Apache Configurations¶
For ownCloud to work correctly, we need the module . Enable it by running:
Additional recommended modules are , , and :
a2enmod headers a2enmod env a2enmod dir a2enmod mimeIf you&#;re running instead of the standard also enable:
You must disable any server-configured authentication for ownCloud, as it uses Basic authentication internally for DAV services. If you have turned on authentication on a parent folder (via e.g. an directive), you can turn off the authentication specifically for the ownCloud entry. Following the above example configuration file, add the following line in the section:
When using SSL, take special note of the ServerName. You should specify one in the server configuration, as well as in the CommonName field of the certificate. If you want your ownCloud to be reachable via the internet, then set both of these to the domain you want to reach your ownCloud server.
Now restart Apache:
If you&#;re running ownCloud in a subdirectory and want to use CalDAV or CardDAV clients make sure you have configured the correct Service discovery URLs.
Multi-Processing Module (MPM)¶
Apache prefork has to be used. Don’t use a threaded like or with , because PHP is currently not thread safe.
Enabling SSL¶
Note
You can use ownCloud over plain HTTP, but we strongly encourage you to use SSL/TLS to encrypt all of your server traffic, and to protect user&#;s logins and data in transit.
Apache installed under Ubuntu comes already set-up with a simple self-signed certificate. All you have to do is to enable the ssl module and the default site. Open a terminal and run:
Note
Self-signed certificates have their drawbacks - especially when you plan to make your ownCloud server publicly accessible. You might want to consider getting a certificate signed by a commercial signing authority. Check with your domain name registrar or hosting service for good deals on commercial certificates.
Installation Wizard¶
After restarting Apache you must complete your installation by running either the graphical Installation Wizard, or on the command line with the command. To enable this, temporarily change the ownership on your ownCloud directories to your HTTP user (see Setting Strong Directory Permissions to learn how to find your HTTP user):
Note
Admins of SELinux-enabled distributions may need to write new SELinux rules to complete their ownCloud installation; see SELinux Configuration Tips.
To use see Installing ownCloud From the Command Line.
To use the graphical Installation Wizard see Installation Wizard.
Setting Strong Directory Permissions¶
After completing installation, you must immediately set the directory permissions in your ownCloud installation as strictly as possible for stronger security. Please refer to Setting Strong Directory Permissions.
Now your ownCloud server is ready to use.
SELinux Configuration Tips¶
See SELinux Configuration for a suggested configuration for SELinux-enabled distributions such as Fedora and CentOS.
www.cronistalascolonias.com.ar Configuration Notes¶
Keep in mind that changes to may have to be configured on more than one ini file. This can be the case, for example, for the setting.
www.cronistalascolonias.com.ar - used by the Web server:
www.cronistalascolonias.com.ar - used by the php-cli and so by ownCloud CRON jobs:
php-fpm Configuration Notes¶
Security: Use at least PHP => or >=
Due to a bug with security implications in older PHP releases with the handling of XML data you are highly encouraged to run at least PHP or when in a threaded environment.
System environment variables
When you are using , system environment variables like PATH, TMP or others are not automatically populated in the same way as when using . A PHP call like can therefore return an empty result. So you may need to manually configure environment variables in the appropropriate ini/config file.
Here are some example root paths for these ini/config files:
| Ubuntu/Mint | CentOS/Red Hat/Fedora |
In both examples, the ini/config file is called , and depending on the distro version or customizations you have made, it may be in a subdirectory.
Usually, you will find some or all of the environment variables already in the file, but commented out like this:
Uncomment the appropriate existing entries. Then run to confirm your paths, for example:
If any of your system environment variables are not present in the file then you must add them.
When you are using shared hosting or a control panel to manage your ownCloud VM or server, the configuration files are almost certain to be located somewhere else, for security and flexibility reasons, so check your documentation for the correct locations.
Please keep in mind that it is possible to create different settings for and , and for different domains and Web sites. The best way to check your settings is with PHP Version and Information.
Maximum upload size
If you want to increase the maximum upload size, you will also have to modify your configuration and increase the and values. You will need to restart and your HTTP server in order for these changes to be applied.
.htaccess notes for Apache
ownCloud comes with its own file. Because can&#;t read PHP settings in these settings and permissions must be set in the file.
