To install Apache from Source Code on CentOS 6

Apache is a web server used to server web page content over HTTP and HTTPS protocol. For the easy installation of Apache web server we normally use yum install command to install Apache in the system. In this tutorial, we will install Apache by compiling from it' s source code. For compling Apache from it' s source it will require for APR and APR-UTIL, which means Apache Portable Runtime (APR). This tutorial will cover the ground on the installation of Apache from Source code on CentOS 6.

Remove the previous installation of Apache web server in the system if it is installed via yum command.

Installation procedure

To proceed with the installation procedure, run the below command to install all the required packages for the source code compilation of Apache and press y to continue with the installation.

All the required packages has been downloaded. Now extract the packages by running the tar command as follows. 

[root@linuxhelp ~]# tar -xzf httpd-2.4.28.tar.gz
[root@linuxhelp ~]# tar -xzf apr-1.6.2.tar.gz
[root@linuxhelp ~]# tar -xzf apr-util-1.6.0.tar.gz

Next we need to place apr and apr-util directory inside srclib directory which is located under HTTPD directory, and the name should be in apr and apr-util. Use below command to move apr and apr-util directory to the respective directory. 

[root@linuxhelp ~]# mv apr-1.6.2 httpd-2.4.28/srclib/apr
[root@linuxhelp ~]# mv apr-util-1.6.0 httpd-2.4.28/srclib/apr-util

Now move to HTTPD directory. 

[root@linuxhelp ~]# cd httpd-2.4.28

Compilation of Apache source

To build configure script, execute the following buildconf script file as follows. 

[root@linuxhelp httpd-2.4.28]# ./buildconf 
found apr source: srclib/apr
found apr-util source: srclib/apr-util

Next run the configure command as shown below. You can change the default Apache installation directory path, here we have mentioned /usr/local/apache2 directory path. 

[root@linuxhelp httpd-2.4.28]# ./configure --enable-ssl --enable-so --with-mpm=event --with-included-apr --prefix=/usr/local/apache2

Now the Apache is successfully installed on the server from it' s source code. Next run the httpd -v command to check Apache version. A error may appear as shown below. 

[root@linuxhelp ~]# httpd -v
bash: httpd: command not found

To remove that error, create a HTTPD commad manually. Create a script file for httpd command under /etc/profile.d/ directory. Enter the following line in the file and save it. 

[root@linuxhelp ~]# vim /etc/profile.d/httpd.sh
pathmunge /usr/local/apache2/bin

The file has been created, now logout from the current session and relogin to reload the profile. Check the Apache version by running the following command. 

[root@linuxhelp ~]# httpd -v
Server version: Apache/2.4.28 (Unix)
Server built:   Oct 11 2017 06:10:14

Create an init script for managing httpd service. So create a httpd file under /etc/init.d/ directory using vim editor and make the following changes in the file. Save and exit the file. 

[root@linuxhelp ~]# vim /etc/init.d/httpd

#!/bin/sh
#

echo -n " Starting httpd: "

echo

stop)
echo -n " Shutting down httpd: "

echo

rm -f /var/run/httpd.pid

status httpd

$0 stop
$0 start
  
reload)
echo -n " Reloading httpd: " 
killproc httpd -HUP
echo
  
*)
echo " Usage: $0 {start|stop|restart|reload|status}" 
exit 1
esac

exit 0

Create the new init script for httpd executable using below command. 

[root@linuxhelp ~]# chmod +x /etc/init.d/httpd

Now manage httpd service via command line as shown below. 

[root@linuxhelp ~]# service httpd start
Starting httpd:                                            [  OK  ]
[root@linuxhelp ~]# chkconfig httpd on

Switch over to the browser and enter the IP address for the Apache server to run in the target system. It runs without any glitches.

Q

Where can I find the Apache license?

A

See the following links; 2.0 is the current version while 1.1 and 1.0 are older versions that the ASF no longer use:

Apache License 2.0: http://www.apache.org/licenses/LICENSE-2.0.txt

Apache Software License 1.1: http://www.apache.org/licenses/LICENSE-1.1.txt

Apache Software License 1.0: http://www.apache.org/licenses/LICENSE-1.0.txt

Q

Why are the license files for the different Apache Software Foundation projects different?

A

While the core Apache developed code will be under one of the Apache licenses, other third party works may have been included and their license text may have been added to the Apache projects' LICENSE or NOTICE files. Alternatively, they may be available separately.

Q

Is software from The Apache Software Foundation free of charge?

A

Yes. All software developed by all projects of The Apache Software Foundation is freely available without charge from the Foundation's Web sites. This is specified in the Foundation's Articles of Incorporation and explained in more detail about why our software is always free (no charge).

Q

Is there a fee for using Apache software in a commercial product?

A

No. We do not distinguish between personal, internal, or commercial use of our software, nor does the ASF charge for any of them. Packaging and redistribution of any of it is subject to the terms of our license , however.

Q

Does the X Project really have to go in the Incubator to get to Apache?

A

Yes. Code that has existed outside the ASF can only enter the ASF through the Incubator. There is no other option. The Incubator, among other things, is where the due-diligence of making sure the licence is correct, the copyright license is received, and all of the initial developers submit their CLAs. The Incubator is also the place where projects can familiarize themselves with how the ASF works under the guidance of Incubator PMC members (mentors).
