A DHS sweep of the network showed that one of the researchers Macs is running a non-safe version of Apache (2.4.25) and they would like him to update to at least 2.4.27.
He is having difficulty getting MacOS to use the new version of Apache rather than the one installed by default with Sierra. His issues are:
Mac OS X 10.12.6 Sierra
I have installed httpd 2.4.27 . . . /usr/local/apache2/bin/
but the default httpd running is located at /usr/sbin/
I cannot install a new httpd into /usr/sbin/ - no write persmissions for sudo
I made a root user active - but "root" does not have write permissions for /usr/sbin/ either
I cannot find any source on the web that describes how to change the httpd path from the default system version (/usr/sbin/httpd) to a new USER installed version, like /usr/local/apache2/bin/httpd
My Google-foo is failing me in finding a walk through for this scenario.
