Oracle Linux/Apache httpd

Installing Apache HTTPD from source

More recently CVEs have been discovered in the latest versions of httpd available from the repos, which presents a problem for administrators since they cannot easily upgrade to a patched version. For such cases, sometimes manually compiling httpd from source is the only temporary solution until the repositories are updated or backported.

Remove if already installed

If you already have httpd installed, remove it.

~$ sudo yum remove httpd -y

Install dependencies, download and unpack source

Install the epel repo, then grab some needed packages.

~$ sudo yum install epel-release -y
~$ sudo yum install autoconf expat-devel libtool libnghttp2-devel pcre-devel -y

Next we need to download apache httpd and (2) of apache's runtime libraries.

~$ curl -L https://github.com/apache/httpd/archive/2.4.35.tar.gz -o /tmp/apache/2.4.35.tar.gz --create-dirs
~$ curl -L https://github.com/apache/apr/archive/1.6.5.tar.gz -o /tmp/apache/1.6.5.tar.gz --create-dirs
~$ curl -L https://github.com/apache/apr-util/archive/1.6.1.tar.gz -o /tmp/apache/1.6.1.tar.gz --create-dirs

untar them

~$ tar -zxvf 2.4.35.tar.gz -C /tmp/apache/
~$ tar -zxvf 1.6.5.tar.gz -C /tmp/apache/
~$ tar -zxvf 1.6.1.tar.gz -C /tmp/apache/

Move APR libraries into place. Make sure the new directory names do not have a version number.

~$ cp -r /tmp/apache/apr-1.6.5 /tmp/apache/httpd-2.4.35/srclib/apr
~$ cp -r /tmp/apache/apr-util-1.6.1 /tmp/apache/httpd-2.4.35/srclib/apr-util

Compile time

It's easiest just to be within the directory.

~$ cd /tmp/apache/httpd-2.4.35

Now lets build the conf and then compile including SSL support (mod-ssl)

~$ ./buildconf
~$ ./configure --enable-ssl --enable-so --enable-http2 --with-mpm=event --with-included-apr --with-ssl=/usr/local/openssl --prefix=/usr/local/apache2
~$ make
~$ sudo make install

Add to /usr/bin

So that we can execute httpd, we need to add a symlink to /usr/bin:

~$ sudo ln -s /usr/local/apache2/bin/httpd /usr/bin/httpd
