install letodms on centos6

[seighalani]

hi everyone

i installed letodms4 on centos6.4 64bit. i think there are difficulties in installation method(it is not clear) and please work on it.

step1:download requirements
#yum install php-pear php-pear-Log php-mbstring php-ZendFramework* httpd mysql php-mysql phpmyadmin
#pear install --alldeps MDB2#MySQL
#pear install --alldeps MDB2#MySQLi
#pear install channel://pear.php.net/HTTP_WebDAV_Server-1.0.0RC6


step 2: download letodms , letodms_core , letodms_lucene from this link:

http://sourceforge.net/projects/mydms/fi...4.0.0-RC1/

step3:

extract letodms to this path: /var/www/html
extract letodms_core , letodms_lucene in /var/www/html/letodms
touch /var/www/html/letodms/config/ENABLE_INSTALL_TOOL
chown -R apache. /var/www/html/letodms

step4:
mkdir /opt/letodms
mkdir /opt/letodms/staging
mkdir /opt/letodms/lucene
chown -R apache. /opt/letodms


step5: create letodms database

#mysql -u root -p
>create database leto;
>grant usage on leto.* to leto@localhost identified by 'letoleto';


final step: in the webbrowser

http://localhost/letodms/install/install.php


i think there is a problem in this step and mybe i entered wrong parameter (specially extra include path):

after delete enable_install_tool when i want to connect to letodms console from http://localhost/letodms/index.php it shows me a blank page.
