Remarks:

Problem 1:

Web page cannot create a (/var/www/moodledata ) directory
Solution 1: (off security linux for a while)
set off selinux

Solution 2: (enable web directory writability)
chown 777  /var/www/

Solution 3: (apache ownership of the file [permission])
chown -R apache:apache /var/www/
chown -R apache:apache /var/www/moodle
chown -R apache:apache /var/www/moodledata 

Problem 2:

Cannot load mysql for UTF-8 unicode format

Solution 1:(mysql configuration)
edit /etc/my.cnf

Solution 2: (brute force mysql for setting utf-8)

Problem 3:

SELinux is preventing /usr/sbin/httpd from write access on the directory /var/www/moodledata.

Plugin: catchall
you want to allow httpd to have write access on the moodledata directoryIf you believe that httpd should be allowed write access on the moodledata directory by default.
You should report this as a bug.
You can generate a local policy module to allow this access.
Allow this access for now by executing:
root@localhost# grep httpd /var/log/audit/audit.log | audit2allow -M mypol
root@localhost# semodule -i mypol.p
