With the development of the times, PHP is also being updated. Here we will introduce the PHP5.0 installation, hoping to be helpful to friends who love PHP. It is assumed that you have the Linux version installed and that it runs correctly. Please make sure that a executable C language compiler has been installed in the system, otherwise our operation will not be possible. Moreover, you also need to make sure that you have downloaded all relevant software: the latest MySQL version (now the MySQL 4.1.3 beta version) can be downloaded from MySQL.com. The latest PHP version (now PHP 5.0.0) can be downloaded from Php.net. The latest Apache 2 version (now Apache 2.0.50), download from Apache.org.
The most important point is: in these versions, the combination of Apache 2.0 and PHP 5.0 is not seamless, so they should not be used on the same system at the same time. However, this combination should be beneficial for developing systems. You may also need the following support libraries: the latest version of the libxml2 library (now libxml2 2.6.11), downloaded from XmlSoft.org. The latest version of the zlib library (now zlib 1.2.1) is downloaded from Gzip.org. Copy everything to your /tmp subdirectory and unzip it as follows:
<ol class="dp-xml"> <li class="alt"><span><span>$ cd /tmp </span></span></li> <li class=""><span>$ tar -xzvf mysql-standard-4.1.3-beta-pc-linux-i686.tar.gz </span></li> <li class="alt"><span>$ tar -xzvf php-5.0.0.tar.gz </span></li> <li class=""><span>$ tar -xzvf httpd-2.0.50.tar.gz </span></li> <li class="alt"><span>$ tar -xzvf libxml2-2.6.11.tar.gz </span></li> <li class=""><span>$ tar -xzvf zlib-1.2.1.tar.gz </span></li> </ol>
Install support library
The first step is to check whether you have libxml2 or zlib installed. PHP5.0 installation requires libxml2 2.6.0 (or a better version than libxml2 2.6.0) and zlib 1.0.9 (or a better version than zlib 1.0.9). If neither support library exists, leave it in read-only form, otherwise proceed to the next section. To begin, compile and install the libxml2 XML parser. This parser provides PHP5.0 with the new XML APL installed:
<ol class="dp-xml"> <li class="alt"><span><span>$ cd /tmp/libxml2-2.6.11 $ ./configure </span></span></li> <li class=""><span>$ make && make install </span></li> </ol>
At the end of this step, libxml2 is installed under /usr/local/. If you want to install it elsewhere, you should explicitly specify the prefix option to the configure settings in the previous step.
Step 2: Perform similar operations on zlib:
<ol class="dp-xml"> <li class="alt"><span><span>$ cd /tmp/zlib-1.2.1 $ ./configure </span></span></li> <li class=""><span>$ make && make install </span></li> </ol>
At the end of this step, zlib is also installed under /usr/local/. You can not use the default value and install it elsewhere using the specified prefix option.
Installing Apache
There are two ways to use PHP with Apache Two ways: as a dynamic module, which can be loaded into the Web server in the running state, or as a static module, which can be compiled directly into the Web server code. For this article, we focus on the first way. In order to enable PHP to be dynamically loaded with the Apache2.0 module, the Apache server must be compiled with Dynamic Shared Object (DSO, Dynamic Shared Object). This feature can be enabled by passing the --enable-so parameter to Apache 2.0 configure:
<ol class="dp-xml"> <li class="alt"><span><span>$ cd /tmp/httpd-2.0.50 </span></span></li> <li class=""> <span>$ ./configure </span><span class="attribute"><font color="#ff0000">--prefix</font></span><span>=/usr/local/apache2 --enable-so $ make </span> </li> <li class="alt"><span>&& make install </span></li> </ol>
This process will set up, compile, and install the server to /usr/local/apache2. After completing the installation of MySQL and Apache, the last step is to compile and install PHP. The most critical step in this step is to use a series of stimulus extension functions to provide PHP configure and the correct file path of the external class library. The above example looks quite complicated, but it is not: prefix sets the installation path of PHP5. with-apxs2 tells PHP where to look for Apache 2.0. with-libxml-dir and --with-zlib-dir tell PHP where to place the libxml2 and zlib libraries. The with-mysql variable activates regularmySQL extension functionality. The with-mysqli variable activates the newly added MySQL functionality. The with-gd variable activates GD extension functionality. The with-zlib variable activates the ZLIB compression library. The enable-sockets variable activates the socket communication feature. The enable-soap variable activates SOAP and Web services support.
Of course, you can also try other options and extensions:
<ol class="dp-xml"><li class="alt"><span><span>$ ./configure --help </span></span></li></ol>
Once configure has completed, you can compile and install PHP.
<ol class="dp-xml"> <li class="alt"><span><span>$ make </span></span></li> <li class=""><span> </span></li> <li class="alt"><span>$ make install </span></li> </ol>
It can be noticed that these installation processes can automatically install the PHP module in the correct directory , for Apache 2.0 to find.
