First things first, you're going to need Apache to be installed already.
1. Download Apache from http://httpd.apache.org/download.cgi, this will assume you download the latest version as of this publication, which is 2.4.3. If you use a different one, be sure to change the commands below (since we use the name of the file).
2. Move this to your src folder, at /usr/local/src, and run the following commands, which will un archive the zipped source, in a shell:
cd /usr/local/src
gzip -d httpd-2.4.3.tar.bz2
tar xvf httpd-2.4.3.tar
cd httpd-2.4.3
3. The following command is semi-optional. If you don't mind the default options, which installs it to /usr/local/apache2, you can skip to step 4. If you're interested as to what can be customized, then run this command:
./configure --help
This will give you a list of the options you can change for when it installs.
4. This will install Apache:
./configure --enable-so
make
make install
Note: if you get an error that says something like this: configure: error: no acceptable C compiler found in $PATH, then you need to install a C compiler. This probably won't happen, but if it does, Google "install gcc on [insert your brand of linux]"
5. Yay! Now you can start up and test Apache:
cd /usr/local/apache2/bin
./apachectl start
Then pointing your browser to http://local-host and it should tell you "It Works!"
Note: if you changed where Apache installed, you should adjust the above cd command accordingly.
Now that you have Apache installed, you can install and test PHP!
Again, this assumes you're downloading a certain file, which is a certain version of PHP. And again, this is the latest stable release as of writing this. That file is named php-5.4.9.tar.bz2
1. Download php-5.4.9.tar.bz2 from www.php.net/downloads.php and again place it in your /usr/local/src then run the following commands:
cd /usr/local/src
bzip2 -d php-5.4.9.tar.bz2
tar xvf php-5.4.9.tar
cd php-5.4.9
2. Again, this step is semi optional as it deals with configuring php before you install it. So, if you want to customize the installation, or see how you can customize it:
./configure --help
3. The next commands actually install PHP, with the default apache install location of /usr/local/apache2:
./configure --with-apxs2=/usr/local/apache2/bin/apxs
make
make install
cp php.ini-dist /usr/local/lib/php.ini
4. Open the file /usr/local/apache2/conf/httpd.conf and add the following text:
<FilesMatch "\.ph(p[2-6]?|tml)$">
SetHandler application/x-httpd-php
</FilesMatch>
Then while in that file make sure it has a line that says LoadModule php5_module modules/libphp5.so
5. Now you will want to restart apache and verify that php is installed and woking correctly:
/usr/local/bin/apache2/apachectl restart
No make a file called test.php in your /usr/local/apache2/htdocs folder with the following line in it:
<?php phpinfo(); ?>
Now point your favorite internet browser at http://local-host/test.php and it should tell you all about your working php installation.
