How to install Apache from Source Code on CentOS 7

To install Apache from Source Code on CentOS 7  

In our previous article, we have been briefed about the installation of Apache from Source code on CentOS 6. Now, we will see about the installation of Apache from source code on CentOS 7. Apache is a web server used to serve web page content over HTTP and HTTPS protocol. For the easy installation of Apache web server we normally use yum install command. In this tutorial, we will install Apache by compiling from it's source code. For compiling Apache from its source, it will require for APR and APR-UTIL, which means Apache Portable Runtime (APR)

 

Remove any the previous installation of Apache if it is installed from yum command in the target system.

 

Installation procedure

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

[root@linuxhelp1 ~]# yum groupinstall "Development Tools" -y
Loaded plugins: fastestmirror, langpacks
There is no installed groups file.
Maybe run: yum groups mark convert (see man yum)

Now install pcre and pcre-devel packages which is also required for Apache installation by running the following command.

Download the Apache source code along with apr and apr-util from Apache's official website or from Git repository by using the following URLs

Apache httpd    -       https://github.com/apache/httpd/releases
Apr                   -        https://github.com/apache/apr/releases
Apr-util             -        https://github.com/apache/apr-util/releases

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

[root@linuxhelp1 ~]# tar -xzf httpd-2.4.28.tar.gz
[root@linuxhelp1 ~]# tar -xzf apr-1.6.2.tar.gz
[root@linuxhelp1 ~]# 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 the following command to move apr and apr-util directory to the respective directory. 

[root@linuxhelp1 ~]# mv apr-1.6.2 httpd-2.4.28/srclib/apr
[root@linuxhelp1 ~]# mv apr-util-1.6.0 httpd-2.4.28/srclib/apr-util

Now move to HTTPD directory. 

[root@linuxhelp1 ~]# cd httpd-2.4.28

 

Compilation of Apache source
To build configure script, execute the following buildconf script file as follows. 

[root@linuxhelp1 httpd-2.4.28]# ./buildconf 
found apr source: srclib/apr
found apr-util source: srclib/apr-util
rebuilding srclib/apr/configure
buildconf: checking installation...

buildconf: copying libtool helper files using /usr/bin/libtoolize
.
.
rebuilding rpm spec file
fixing timestamps for ap_expr sources

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@linuxhelp1 httpd-2.4.28]# ./configure --enable-ssl --enable-so --with-mpm=event --with-included-apr --prefix=/usr/local/apache2

    LIBS:           
    CPPFLAGS:        -DLINUX -D_REENTRANT -D_GNU_SOURCE
    C preprocessor: gcc -E

Execute the make command to prepare the files for the installation of Apache.

[root@linuxhelp1 httpd-2.4.28]# make

Execute the make install command to install Apache in it's appropriate directory. 

[root@linuxhelp1 httpd-2.4.28]# make install
Making install in srclib
make[1]: Entering directory `/root/httpd-2.4.28/srclib'

.
.
mkdir /usr/local/apache2/manual
make[1]: Leaving directory `/root/httpd-2.4.28'

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

[root@linuxhelp1 httpd-2.4.28]# 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@linuxhelp1 httpd-2.4.28]# vim /etc/profile.d/httpd.sh
pathmunge /usr/local/apache2/bin

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

[root@linuxhelp1 ~]# httpd -v
Server version: Apache/2.4.28 (Unix)
Server built:   Oct 13 2017 23:23:07

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@linuxhelp1 ~]# vim /etc/systemd/system/httpd.service

[Unit]

[Install]
WantedBy=multi-user.target

Reload the Systemctl daemon by executing the following command. 

[root@linuxhelp1 ~]# systemctl daemon-reload

Now start and enable your Apache httpd service with the following command.

[root@linuxhelp1 ~]# systemctl start httpd
[root@linuxhelp1 ~]# systemctl enable httpd
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /etc/systemd/system/httpd.service.

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.Apache server

Thus we conclude the installation and configuration of Apache from its Source Code on CentOS 7.
