How to Compile Apache HTTP Server 2.4.3 from Source on CentOS 6.3

This post describes how do I compile the Apache HTTP Server 2.4.3 from Source tarball on CentOS Linux 6.3. I am writing this blog post is because the YUM server does not provide any HTTPD packages on Apache HTTP Server version 2.4.3. At the time of writing of this blog post, the version provided by the YUM repository is version 2.2.15.

Prerequisite

Install the required packages to compile the Apache HTTP Server by using yum.
  • yum install gcc
  • yum install gcc-c++

Compile the Apache Portable Runtime Project

The Apache Portable Runtime Project (APR) is required for building Apache HTTP Server 2.4.3 on CentOS 6.3.

1. Download the Apache Portable Runtime project from http://apr.apache.org. As the time of writing this blog post, APR version 1.4.6 was used.
2. Extract the Unix Source file downloaded

tar zxvf apr-1.4.6.tar.gz


3. Run the following command to compile the Apache Portable Runtime project

cd apr-1.4.6
./configure --prefix=/opt/apr-1.4.6
make
make install

4. The Apache Portable Runtime project should be installed at the location /opt/apr-1.4.6

Compile the Apache Portable Runtime Utility Library

The Apache Portable Runtime Utility (APR-util) Library is also required for building Apache HTTP Server 2.4.3 on CentOS 6.3

1. Download the Apache Portable Runtime Utility project from http://apr.apache.org. As the time of writing this blog post, APR-util version 1.5.1 was used.
2. Extract the Unix Source file downloaded

tar zxvf apr-util-1.5.1.tar.gz

3. Run the following command to compile the Apache Portable Runtime Utility Library


cd apr-util-1.5.1
./configure --prefix=/opt/apr-util-1.5.1
make
make install

4. The Apache Portable Runtime project should be installed at the location /opt/apr-util-1.5.1

Compile the Perl Compatible Regular Expression Library

The Perl Compatible Regular Expression Library (PCRE) is a set of functions that implement regular expression pattern matching using the same syntax and semantics as Perl 5. It is used by Apache HTTP Server 2.4.

1. Download the PCRE library from http://www.pcre.org
2. Extract the Unix Source file downloaded

tar zxvf pcre-8.32.tar.gz

3. Run the following command to compile the PCRE Library. Assuming the directory to be installed is /opt/pcre-8.32.

cd pcre-8.32
./configure --prefix=/opt/pcre-8.32
make
make install

4. The PCRE Library should be installed at the location /opt/pcre-8.32

Compile the Apache HTTP Server 2.4.3

Finally, it comes to compiling the Apache HTTP Server 2.4.3

1. Download the Unix Source of Apache HTTP Server 2.4.3 from http://httpd.apache.org
2. Extract the Unix Source file downloaded

tar zxvf httpd-2.4.3.tar.gz

3. Run the following commands to compile the Apache HTTP Server 2.4.3. Assuming the directory to be installed is /opt/httpd-2.4.3

cd httpd-2.4.3
./configure --prefix=/opt/httpd-2.4.3 --with-apr=/opt/apr-1.4.6 --with-apr-util=/opt/apr-util-1.5.1 --with-pcre=/opt/pcre-8.32
make
make install

To start the Apache HTTP Server 2.4.3

Assuming you completed the compiling procedures stated above, run the following command to start the Apache HTTP Server.

cd /opt/httpd-2.4.3/bin
./apachectl start
