Hi, Im follow this steps to preview libreoffice files, but without success. Im using Centos 7.2.

I need help configuring it, thanks in advance:

My config file:

'preview_libreoffice_path' => '/usr/bin/libreoffice',
);

File php.ini:
disable_functions =
;open_basedir = ( ** if I set to /usr/bin/ OC stops ** )

Selinux is disabled;

If I run the libreoffice manually it works:
->/usr/bin/libreoffice --headless --convert-to pdf test\ word\ format.doc
convert /var/owncloud/data/admin/files/Documentos/test word format.doc -> /var/owncloud/data/admin/files/Documentos/test word format.pdf using writer_pdf_Export
