Hi,

“I don’t know if my sistem is LEMP or XAMP or LAMP… How I discover it?” :

Your System is CentOS 6 :-)

“And I want download all file of my webserver to my local host, because I need search files in my explorer, because in terminal commands I don’t find files.” :

The unsafe way

yum install zip
zip -r /var/www/html/html.zip /var/www/html

Now you can dowload all files at domain.com_or_IP/html.zip

The safe way

yum install zip
zip -r /var/www/html/html.zip /root

Use SFTP and download it
