APR and APR-utill 

Either you may install APR and APR-Utill on your system already or you may use both with Apache installation by downloading latest version from apache apr website. User needs to unpack the both folder into ./srclib/apr and ./srclib/apr-util ( here user has to make sure both directories names do not contain version numbers : Example :-  ./srclib/apr & ./srclib/apr-utill ). Some platforms may require -dev package to be installed for httpd server.

PCRE ( Perl -Compatible Regular Expression Library )

This library files are required for Apache HTTP server 2.4.9. it is not bundled with https, user may download it from http://www.pcre.org. First, User has to build pcre library for the system that will create pcre-config scripts installed by the PCRE build. To configuring Apache , user needs to add  --with-pcre parameter.

Configure PCRE

$ cd pcre-8.35

$ ./configure --prefix=PREFIX

PREFIX :- Here prefix represents home directory of pcre library. 

$ make

$ make install

above command will generate the pcre-config scripts under the pcre home directory. this pcre-config will be used during Apache installation.

Apache Installation Steps

Extraction

  $ gzip -d httpd-xx.tar.gz

 $ tar xvf httpd-xx.tar

  $ cd httpd-NN

Enter into the 03-httpd directory.

Configure Apache

Copy the APR, APR-Utill and pcre directory into the ./srclib of Apache installation.

$ ./configure --prefix=PREFIX --with-included-apr --with-included-pcre=<PATH TO PCRE-CONFIG generated at above step>

PREFIX = it is home directory of installation or by default location system will take /usr/local/apache2

Note :- Here user can add multiple modes for Apache Web server according to requirement.

Compile & install Apache

$ make 

Above command will compile the Apache package and file system.

$ make install

Upon successfully completion of above command. you can access your Apache HTTP server at port 80. To test it just hit the URL :- http://<hostname>:80

But you need to start the https service to access this. Please follow the below steps.

$ vi PREFIX/conf/httpd.conf

here user can change the server parameters like hostname, port and modules for the Apache.

$ cd PREFIX/bin

$ ./apachectl -k start  ( To start httpd server)

$ ./apachectl -k stop   ( To stop httpd server)

Other methods

$ /etc/init.d/httpd -start

$ /etc/init.d/httpd -stop

sometimes if service is registered with name "apache" then

$ /etc/intit.d/apache -start
$ /etc/init.d/apache -stop

using service

$ httpd stop
$ service httpd start

Verify httpd process on linux

$ ps -aef | grep httpd

Above command will show the running process information.
