Installing Apache, PHP, and MySQL Under Unix 891 Source Installation Let’s install Apache, PHP, and MySQL under a Unix environment. First, you need to decide which extra modules you will load under the trio. Because some of the examples covered in this book use a secure server for web transactions, you should install an SSLenabled server. For purposes of this book, the PHP configuration is more or less the default setup but also covers ways to enable the gd2 library under PHP. The gd2 library is just one of the many libraries available for PHP.We included this installation step so that you can get an idea of what is required to enable extra libraries within PHP. Compiling most Unix programs follows a similar process. You usually need to recompile PHP after installing a new library, so if you know what you need in advance, you can install all required libraries on your machine and then begin to compile the PHP module. Here, we describe installation on an SuSE Linux server, but the description is generic enough to apply to other Unix servers. Start by gathering the required files for the installation.You need these items: n Apache (http://httpd.apache.org/)—The web server n OpenSSL (http://www.openssl.org/)—Open source toolkit that implements the Secure Sockets Layer n MySQL (http://www.mysql.com/)—The relational database n PHP (http://www.php.net/)—The server-side scripting language n ftp://ftp.uu.net/graphics/jpeg/—The JPEG library, needed for PDFlib and gd n http://www.libpng.org/pub/png/libpng.html—The PNG library, needed for gd n http://www.zlib.net/—The zlib library, needed for the PNG library, above n http://www.libtiff.org/—The TIFF library, needed for PDFlib n ftp://ftp.cac.washington.edu/imap/—The IMAP c client, needed for IMAP If you want to use the mail() function, you will need to have an MTA (mail transfer agent) installed, although we do not go through this here. We assume that you have root access to the server and the following tools installed on your system: n n gzip or gunzip gcc and GNU make When you are ready to begin the installation process, you should start by downloading all tar file sources to a temporary directory. Make sure you put them somewhere with plenty of space. In our case, we chose /usr/src for the temporary directory. You should download them as root to avoid permissions problems.
892 Appendix A Installing PHP and MySQL Installing MySQL In this section, we show you how to do a binary install of MySQL.This type of install automatically places files in various locations.We chose the following directories for the remainder of our trio: n n /usr/local/apache2 /usr/local/ssl You can install the applications in different directories by changing the prefix option before installing. Let’s begin! Become root by using su: $ su root Then enter the user root’s password. Next, change to the directory where you have stored the source files. For example, use # cd /usr/src MySQL recommends that you download a binary of MySQL instead of compiling from scratch.Which version to use depends on what you want to do. Although MySQL prerelease versions are generally very stable, you may choose not to use them on a production site. If you are learning and experimenting on your own machine, you may choose to use one of these versions. You should download the following packages: MySQL-server-VERSION.i386.rpm MySQL-Max-VERSION.i386.rpm MySQL-client-VERSION.i386.rpm (The word VERSION is a placeholder for the version number. For whichever version you choose, make sure that you choose a matching set.) If you intend to run the MySQL client and server on this machine and to compile MySQL support into other programs such as PHP, you need all these packages. Enter the following commands to install the MySQL servers and client: rpm -i MySQL-server-VERSION.i386.rpm rpm -i MySQL-Max-VERSION.i386.rpm rpm -I MySQL-client-VERSION.i386.rpm The MySQL server should now be up and running. Now it’s time to give the root user a password. Make sure you replace new-password in the following command with a password of your choice; otherwise, new-password will be your root password: mysqladmin -u root password ‘new-password’ When you install MySQL, it automatically creates two databases. One is the mysql table, which controls users, hosts, and DB permissions in the actual server.The other is a test DB.
