Configuring ownCloud

Increasing file upload limits

Many people use ownCloud as a repository to store files. Because ownCloud runs PHP scripts, its file size upload limits are defined by the system-wide PHP configuration. PHP often has small file upload limits in place to prevent memory overload, but these limits may be too small for uploading large files into your ownCloud repostitory.

To change the PHP file upload limits:

  1. Locate the php.ini file. The php.ini file location depends on which Linux distribution is installed on your system:
    • CentOS and Fedora: The php.ini file is located in the /etc directory .
    • Debian and Ubuntu: The php.ini file is located in the /etc/php5/apache2 directory.
  2. Open the php.ini file, and edit the following settings:

    • upload_max_filesize: This setting defines the maximum file size, in megabytes, that a user can upload.
    • post_max_size: This setting defines the maximum amount of POST data, in megabytes, that a user can submit.
  3. If you experience timeouts or memory errors when uploading large files, you may need to adjust the following php.ini settings as well:

    • memory_limit: This setting defines the maximum amount of memory, in megabytes, that a script can use.
    • max_execution_time: This setting defines the maximum execution time, in seconds, for a script.
    • max_input_time: This setting defines the maximum amount of time, in seconds, that a script can spend to parse request data.

You can customize the appearance of your ownCloud installation by using different themes. However, the ownCloud theme files are not accessible through the ownCloud web interface. You must log in to your server using SSH or SFTP to view and modify theme files. The location of the ownCloud theme files depends on which Linux distribution you have installed:

  • CentOS and Fedora: The theme files are located in the /var/www/html/owncloud/themes directory.
  • Debian and Ubuntu: The theme files are located in the /var/www/owncloud/themes directory.

See the More Information section below for additional information about ownCloud themes.

Using the ownCloud Sync Client

You can install the ownCloud Sync Client to keep a local folder on your desktop synchronized with your ownCloud file repository. The ownCloud Sync Client is available for a wide variety of operating systems. To download the ownCloud Sync Client, please visit

The A2 QuickInstaller currently installs ownCloud version 4.5. Therefore, you should download the Sync Client version 1.0.5 for previous ownCloud versions.

By default, the ownCloud installation is not configured to use secure connections (that is, URLs that begin with https://). Therefore, when you use the Sync Client to create an initial ownCloud connection, you should clear the Use secure connection check box.

Also, ownCloud uses file timestamps to synchronize files. To keep the file timestamps on your local computer and remote server the same, the time zones must be the same as well. Additionally, your local computer's clock should be synchronized with a network time server to ensure that timestamps are accurate.
