You can see here that the context is incorrect for the file to be served by
apache. You can change it using:

"chcon user_u:object_r:httpd_sys_content_t /var/www/html/Alex.html" with no
quotes.

This will change the file to the specific context needed. You can also use
restorecon -R as others have mentioned

You can use "setenforce 0" without the quotes to disable selinux from the
command line till next reboot or until you issue "setenforce 1" - this is
useful for testing as is looking at /var/log/audit/audit.log and also using
commands such as audit2why and audit2allow (I strongly recommend reading at
least the man pages and also such websites as
http://www.nsa.gov/research/selinux/docs.shtml (google selinux))

I recommend that you keep selinux running and enforcing and that you spend
some time learning it. It is very useful. The config files are located here:
/etc/selinux and you can set selinux to be disabled or if you want
permissive i.e. it will not stop you or others doing things but will report
on the violations.

Have fun
