How to install apache without a linux or unix package installer?

Ever wondered why your apache directory layout is different? Take a look at this link:
https://wiki.apache.org/httpd/DistrosDefaultLayout

Download the software from main site or one of the many mirror sites.
Note: apache advise to use the mirror sites to save on bandwidth.

$ wget -L http://mirror.catn.com/pub/apache/httpd/httpd-2.4.25.tar.gz
--2017-01-25 08:52:07--  http://mirror.catn.com/pub/apache/httpd/httpd-2.4.25.tar.gz
Resolving mirror.catn.com (mirror.catn.com)... 87.124.126.49

Saving to: ‘httpd-2.4.25.tar.gz’

Verity the integrity of the downloaded file using the keys.

Download the .asc and keys from the main site not the mirror. http://www.apache.org/dist/httpd/

$ wget  -L http://www.apache.org/dist/httpd/httpd-2.4.25.tar.gz.asc
$ wget  -L http://www.apache.org/dist/httpd/KEYS

Import the keys, in this case for gpg
In this case the signature was signed by: httpd-2.4.25.tar.* are signed by Jim Jagielski 791485A8, check your signature at the end of the web page: http://httpd.apache.org/download.cgi

$ gpg --import KEYS
gpg --verify httpd-2.4.25.tar.gz.asc httpd-2.4.25.tar.gz

Pre-reqs are
Installing apr and apr util, going through the downloading and verifying the integrity of the files.
Download the files from http://apr.apache.org/download.cgi and install into srclib, where you are working from eg: <apache source dir>/srclib/ Create a directory called apr and apr-util and extract the files into these directories, without the version number on them, e.g:

$ pwd
/var/tmp/httpd-2.4.25/srclib
$ ls
apr  apr-util  Makefile.in

Make sure you have the gcc compiler, make, & pcre development tools installed . see this link under requirements: https://httpd.apache.org/docs/2.4/install.html

Compile & Install the software
Note: Here I have just used /usr/local, if I didn't specify the --prefix, the install would have defaulted to /usr/local/apache2, which is better as it keeps all apache related files under that directory.

$ gzip -d httpd-2.4.25.tar.gz
$ tar xvf httpd-2.4.25.tar
$ cd httpd-2.4.25
$ ./configure --with-included-apr --prefix=/usr/local
$ make 
$ sudo make install
$ sudo /usr/local/bin/apachectl -k start
$ ps -ef | grep httpd
root     31320     1  0 10:14 ?        00:00:00 /usr/local/bin/httpd -k start
daemon   31321 31320  0 10:14 ?        00:00:00 /usr/local/bin/httpd -k start
daemon   31322 31320  0 10:14 ?        00:00:00 /usr/local/bin/httpd -k start
daemon   31323 31320  0 10:14 ?        00:00:00 /usr/local/bin/httpd -k start
