If you are not familiar with building software on Linux, this is the way to go. </p> <p class="simpara"> The first decision you need to make is whether you want to install Apache 1.3.x or Apache 2.x. The corresponding PHP packages are respectively named libapache-mod-php* and libapache2-mod-php*. The steps given below will use Apache 1.3.x. Please note that, as of this writing, there is no official Debian packages of PHP 5. Then the steps given below will install PHP 4. </p> <p class="simpara"> PHP is available in Debian as CGI or CLI flavour too, named respectively php4-cgi and php4-cli. If you need them, you'll just have to reproduce the following steps with the good package names. Another special package you'd want to install is php4-pear. It contains a minimal PEAR installation and the <strong class="command">pear</strong> commandline utility. </p> <p class="simpara"> If you need more recent packages of PHP than the Debian's stable ones or if some PHP modules lacks the Debian official repository, perhaps you should take a look at <a href="http://www.apt-get.org/" class="link external">» http://www.apt-get.org/</a>. One of the results found should be <a href="http://www.dotdeb.org/" class="link external">» Dotdeb</a>. This unofficial repository is maintained by <a href="mailto:gui@php.net" class="link external">» Guillaume Plessis</a> and contains Debian packages of the most recent versions of PHP 4 and PHP 5. To use it, just add the to following two lines to your <var class="filename">/etc/apt/sources.lists</var> and run <strong class="command">apt-get update</strong> : </p> <div class="example"> <p><b>Example #1 The two Dotdeb related lines</b></p> <div class="example-contents"><div class="cdata"><pre>deb http://packages.dotdeb.org stable alldeb-src http://packages.dotdeb.org stable all</pre></div> </div> </div> <p class="simpara"> The last thing to consider is whether your list of packages is up to date. If you have not updated it recently, you need to run <strong class="command">apt-get update</strong> before anything else. This way, you will be using the most recent stable version of the Apache and PHP packages. </p> <p class="simpara"> Now that everything is in place, you can use the following example to install Apache and PHP: </p> <div class="example" id="install.unix.debian.apt.example" name="install.unix.debian.apt.example"> <p><b>Example #2 Debian Install Example with Apache 1.3</b></p> <div class="example-contents"><div class="cdata"><pre># apt-get install libapache-mod-php4</pre></div> </div> </div> <p class="simpara"> APT will automatically install the PHP 4 module for Apache 1.3, and all its dependencies and then activate it. If you're not asked to restart Apache during the install process, you'll have to do it manually : </p> <div class="example" id="install.unix.debian.apt.example2" name="install.unix.debian.apt.example2"> <p><b>Example #3 Stopping and starting Apache once PHP 4 is installed</b></p> <div class="example-contents"><div class="cdata"><pre># /etc/init.d/apache stop# /etc/init.d/apache start</pre></div> </div> </div> </div> <div id="install.unix.debian.config" class="sect2"> <h3 class="title">Better control on configuration</h3> <p class="simpara"> In the last section, PHP was installed with only core modules. This may not be what you want and you will soon discover that you need more activated modules, like MySQL, cURL, GD, etc. </p> <p class="simpara"> When you compile PHP from source yourself, you need to activate modules via the <strong class="command">configure</strong> command. With APT, you just have to install additional packages. They're all named 'php4-*' (or 'php5-*' if you installed PHP 5 from a third party repository). </p> <div class="example" id="install.unix.debian.config.example" name="install.unix.debian.config.example"> <p><b>Example #4 Getting the list of PHP additional packages</b></p> <div class="example-contents"><div class="cdata"><pre># dpkg -l 'php4-*'</pre></div> </div> </div> <p class="simpara"> As you can see from the last output, there's a lot of PHP modules that you can install (excluding the php4-cgi, php4-cli or php4-pear special packages). Look at them closely and choose what you need. If you choose a module and you do not have the proper libraries, APT will automatically install all the dependencies for you. </p> <p class="simpara"> If you choose to add the MySQL, cURL and GD support to PHP the command will look something like this: </p> <div class="example" id="install.unix.debian.config.example2" name="install.unix.debian.config.example2"> <p><b>Example #5 Install PHP with MySQL, cURL and GD</b></p> <div class="example-contents"><div class="cdata"><pre># apt-get install php4-mysql php4-curl php4-gd</pre></div> </div> </div> <p class="simpara"> APT will automatically add the appropriate lines to your different <var class="filename">php.ini</var> (<var class="filename">/etc/php4/apache/php.ini</var>, <var class="filename">/etc/php4/cgi/php.ini</var>, etc). </p> <div class="example" id="install.unix.debian.config.example3" name="install.unix.debian.config.example3"> <p><b>Example #6 These lines activate MySQL, cURL and GD into PHP</b></p> <div class="example-contents"><div class="cdata"><pre>extension=mysql.soextension=curl.soextension=gd.so</pre></div> </div> </div> <p class="simpara"> You'll only have to stop/start Apache as previously to activate the modules. </p> </div> <div id="install.unix.debian.faq" class="sect2"> <h3 class="title">Common Problems</h3> <ul class="itemizedlist"> <li class="listitem"> <span class="simpara"> If you see the PHP source instead of the result the script should produce, APT has probably not included <var class="filename">/etc/apache/conf.d/php4</var> in your Apache 1.3 configuration. Please ensure that the following line is present in your <var class="filename">/etc/apache/httpd.conf</var> file then stop/start Apache: </span> <div class="example" id="install.unix.debian.faq.example" name="install.unix.debian.faq.example"> <p><b>Example #7 This line activates PHP 4 into Apache</b></p> <div class="example-contents"><div class="cdata"><pre># Include /etc/apache/conf.d/</pre></div> </div> </div> </li> <li class="listitem"> <span class="simpara"> If you installed an additional module and if its functions are not available in your scripts, please ensure that the appropriate line is present in your <var class="filename">php.ini</var>, as seen before. APT may fail during the installation of the additional module, due to a confusing debconf configuration. </span> </li> </ul> </div></div><hr /><div style="text-align: center;"> <div class="prev" style="text-align: left; float: left;"><a href="install.unix.html">Installation on Unix systems</a></div> <div class="next" style="text-align: right; float: right;"><a href="install.macosx.html">Installation on Mac OS X</a></div> <div class="up"><a href="install.unix.html">Installation on Unix systems</a></div> <div class="home"><a href="index.html">PHP Manual</a></div></div></body></html>⌨️ 快捷键说明
