Description of problem:
I believe it happedned because I have tried to change the context of an SELinux protected area under the home directory of root when testing something with docker...
SELinux is preventing /usr/local/apache2/bin/httpd from 'open' accesses on the file /usr/local/apache2/htdocs/index.html.

*****  Plugin restorecon (99.5 confidence) suggests   ************************

If you want to fix the label. 
/usr/local/apache2/htdocs/index.html default label should be usr_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /usr/local/apache2/htdocs/index.html

*****  Plugin catchall (1.49 confidence) suggests   **************************

If you believe that httpd should be allowed open access on the index.html file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep httpd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
