Just installed Prestashop in CentOS 7 and it is working very nice.
Would you please consider adding it to the script installers? Some webhostings has one click installer for prestashop but I am not sure what control panel they are using.
Here is a quick list of what you need to get started with the installation of PrestaShop 1.6. Should you not feel comfortable with the lack of details, you will find detailed instructions in the sections following this one.
System requirements: PHP 5.2 or later. Useful settings (in the php.ini file): allow_url_fopen set to On, register_globals set to Off, magic_quotes_* set to Off, safe_mode set to Off, upload_max_filesize set to "16M" (ou plus). Useful PHP extensions (in the php.ini file): PDO_MySQL, cURL, SimpleXML, mcrypt, GD, OpenSSL, DOM, SOAP. Useful server tools: cron/crontab, Memcached. MySQL 5.0 or later. Better if: Unix/Linux hosting. Apache Web Server 1.3 or later or nginx Web Server. Apache module settings: mod_rewrite enabled, mod_security disabled, mod_auth_basic disabled. At least 64 Mb of RAM dedicated to PHP. The more the better. Access codes to your FTP server, your MySQL database These should be provided by your web-host if you are not doing a local installation. Any text editor. Any FTP client. Any modern Web browser (if using Internet Explorer: at least IE8).
You also need to know which URL on your domain you want your store(s) to be accessible from.
