Example:

/opt/my_apache_new TO /opt/my_apache

After renaming i am getting below error:

./apachectl -V
./apachectl: line 79:  4425 Segmentation fault      (core dumped) $HTTPD "$@"

"Job for apache2.service failed because the control process exited with error code.
See "systemctl status apache2.service" and "journalctl -xe" for details." 

But I’ve changed the apache.conf how it is before do it and now works… help please. And this is a good article (but it don’t works for me ;-D )

To change Apache2 server name to anything, refer to this guide: https://www.tecmint.com/change-apache-server-name-to-anything-in-server-headers/

If you only want to use the htaccess file, consult its documentation: https://httpd.apache.org/docs/2.4/howto/htaccess.html
