File permissions issue

Hello,
I’m trying to install SuiteCRM 7.7.5 on Centos 6.8 with MySQL 5.6.33 and Php 5.5.38.
Following your guide https://suitecrm.com/wiki/index.php/Installation I set
sudo chown -R apache:apache
sudo chmod -R 755 .
sudo chmod -R 775 cache custom modules themes data upload config_override.php

Then, I browse the installation wizard and it asks me to set 766 some folders and config_override.php ok
Now I get this error:
Writable Cache Sub-Directories

The files or directories listed below are not writeable or are missing and cannot be created. Depending on your Operating System, correcting this may require you to change permissions on the files or parent directory (chmod 755), or to right click on the parent directory and uncheck the ‘read only’ option and apply it to all subfolders.

Please fix the following files or directories before proceeding:
[…]/cache/images
[…]/cache/layout
[…]/cache/pdf
[…]/cache/xml
[…]/cache/include/javascript

I try all combination: 755, 775, 766, 777 but nothing.
Please, what I’m doing wrong? What is the correct guide to install SuiteCRM?
Thank you
