Setting up an Apache HTTP server

Through some config file hacking, I have managed to set up an Apache HTTP server on my Macbook.  I did this so that I could test the full functionality of PHP.  Since PHP is one of the top most needed skills for freelance coding jobs, I figured it would be a good idea to learn it, and of course to use any of the features of PHP beyond just the core language, you need a web server.

Starting the Apache server is pretty easy.  All you have to do is type sudo httpd at the command line (assuming Apache is installed on your system, which I think it is for most Unix-based systems). It is recommended that you use apachectl as a frontend instead of using httpd directly, but I couldn’t seem to get this to work, so to start Apache I use sudo httpd and to stop it I use sudo killall httpd.

Now configuring the server to use PHP was somewhat more difficult, though still not too much so. First of all, for a server to use PHP, the PHP DOS initialization file needs to be present as /usr/local/lib/php.ini. After some digging around, I found the PHP ini file at etc/php.ini.default, so I just copied it (changing the filename of course).

The next thing I had to do was tell Apache to load the PHP module at startup. This is done by editing the file /etc/apache2/httpd.conf and uncommenting the appropriate code line.  It must be remembered that editing this file requires root privileges.

httpd.conf-uncomment

The appropriate line is


LoadModule php5_module libexec/apache2/libphp5.so

…Shown here already uncommented.

The next thing you have to do is find out what directory Apache is using to serve files to clients. This is determined by the DocumentRoot environment variable, and controlled by a <Directory> tag.

http.conf-root

Here we see that the server’s filesystem is rooted at /Library/WebServer/Documents. Of course this is Mac-specific, and the root will be different on other systems, and we can also change it, though I felt no need to.

If you title a document “index.html”, “index.php”, etc. then this will be the file that the client goes to when the user types your domain name without appending a path at the end. Also, if you title a document, say, my-pictures.html, the file extension can be omitted in the URL.
