How To Set Permissions To Upload-tmp Owncloud 10

Uploading large files > 512MB¶

The default maximum file size for uploads, in ownCloud, is 512MB. Y'all can increment this limit up to the maximum file size which your filesystem, operating organisation, or other software allows, for example:

• < 2GB on a 32Bit Bone-architecture
• < 2GB with IE6 - IE8
• < 4GB with IE9 - IE11

64-fleck filesystems accept much college limits. Delight consult the documentation for your filesystem.

Note

The ownCloud sync client itself however is able to upload files of whatever size, as it uploads files by transmitting them in pocket-size chunks. But, it can never exceed the maximum file size limits of the remote host.

Organisation Configuration¶

• Make sure that the latest version of PHP (at least 5.6) is installed
• Disable user quotas, which makes them unlimited
• Your temp file or partition has to exist big plenty to hold multiple parallel uploads from multiple users; e.g. if the max upload size is 10GB and the average number of users uploading at the aforementioned time is 100: temp space has to agree at least 10x100 GB

Configuring Your Web server¶

Note

ownCloud comes with its own owncloud/.htaccess file. Because php-fpm tin can't read PHP settings in .htaccess these settings must be set in the owncloud/.user.ini file.

Set the following two parameters within the respective php.ini file (see the Loaded Configuration File section of PHP Version and Information to discover your relevant php.ini files)

                            php_value              upload_max_filesize              =              16              Chiliad              php_value              post_max_size              =              16              G            

Adjust these values for your needs. If you come across PHP timeouts in your logfiles, increase the timeout values, which are in seconds:

                            php_value              max_input_time              3600              php_value              max_execution_time              3600            

The mod_reqtimeout Apache module could also stop large uploads from completing. If y'all're using this module and getting failed uploads of big files either disable it in your Apache config or raise the configured RequestReadTimeout timeouts.

There are also several other configuration options in your Web server config which could prevent the upload of larger files. Please see the manual of your Spider web server for how to configure those values correctly:

Apache with mod_fcgid¶

• FcgidMaxRequestInMem
• FcgidMaxRequestLen

Note

If you are using Apache/2.4 with mod_fcgid, equally of February/March 2016, FcgidMaxRequestInMem still needs to be significantly increased from its default value to avoid the occurence of segmentation faults when uploading big files. This is non a regular setting but serves as a workaround for Apache with mod_fcgid issues #51747.

Setting FcgidMaxRequestInMem significantly college than normal may no longer be necessary, in one case bug #51747 is fixed.

NGINX¶

• client_max_body_size
• fastcgi_read_timeout
• client_body_temp_path

Since NGINX one.7.eleven a new config option fastcgi_request_buffering is availabe. Setting this option to fastcgi_request_buffering off; in your NGINX config might help with timeouts during the upload. Furthermore information technology helps if you're running out of disc space on the /tmp partition of your system.

For more than info how to configure NGINX to raise the upload limits see also this wiki entry.

Notation

Make sure that client_body_temp_path points to a partition with adequate infinite for your upload file size, and on the aforementioned sectionalisation equally the upload_tmp_dir or tempdirectory (see below). For optimal functioning, place these on a separate difficult bulldoze that is defended to swap and temp storage.

If your site is behind a NGINX frontend (for instance a loadbalancer):

By default, downloads will be limited to 1GB due to proxy_buffering and proxy_max_temp_file_size on the frontend.

• If you tin access the frontend's configuration, disable proxy_buffering or increase proxy_max_temp_file_size from the default 1GB.
• If you do not have access to the frontend, fix the X-Accel-Buffering header to add_header X-Accel-Buffering no; on your backend server.

Configuring PHP¶

If you don't desire to use the ownCloud .htaccess or .user.ini file, you may configure PHP instead. Make certain to comment out whatever lines .htaccess pertaining to upload size, if you entered whatsoever.

If y'all are running ownCloud on a 32-bit organisation, whatever open_basedir directive in your php.ini file needs to exist commented out.

Set the following two parameters inside php.ini , using your own desired file size values:

                            upload_max_filesize              =              16              G              post_max_size              =              xvi              G            

Tell PHP which temp file you want it to use:

                            upload_tmp_dir              =              /              var              /              big_temp_file              /            

Output Buffering must be turned off in .htaccess or .user.ini or php.ini , or PHP volition render retentiveness-related errors:

• output_buffering = 0

Configuring ownCloud¶

As an alternative to the upload_tmp_dir of PHP (e.g., if you lot don't have access to your php.ini ) you tin besides configure a temporary location for uploaded files by using the tempdirectory setting in your config.php (Encounter Config.php Parameters).

If you have configured the session_lifetime setting in your config.php (See Config.php Parameters) file then make sure it is not as well depression. This setting needs to be configured to at least the fourth dimension (in seconds) that the longest upload volition accept. If unsure remove this completely from your configuration to reset it to the default shown in the config.sample.php .

Configuring upload limits within the GUI¶

If all prerequisites described in this documentation are in place an admin can change the upload limits on demand past using the File handling input box within the administrative backend of ownCloud.

Depending on your surround you might get an insufficient permissions message shown for this input box.

To be able to use this input box you need to make sure that:

• Your Web server is exist able to apply the .htaccess file shipped by ownCloud (Apache only)
• The user your Web server is running as has write permissions to the files .htaccess and .user.ini

Set Strong Directory Permissions might preclude write admission to these files. As an admin yous demand to decide between the ability to use the input box and a more secure ownCloud installation where you need to manually modify the upload limits in the .htaccess and .user.ini files described above.

Full general upload issues¶

Various environmental factors could crusade a brake of the upload size. Examples are:

• The LVE Manager of CloudLinux which sets a I/O limit
• Some services like Cloudflare are also known to cause uploading bug
• Upload limits enforced past proxies used by your clients
• Other webserver modules like described in General Troubleshooting
