If you are not familiar with building software on - Linux, this is the way to go. - - If you have built your Gentoo system so far, you are probably used to - Portage already. Installing Apache and PHP is no different than the - other system tools. - - The first decision you need to make is whether you want to install - Apache 1.3.x or Apache 2.x. While both can be used with PHP, the steps - given bellow will use Apache 1.3.x. Another thing to consider is - whether your local Portage tree is up to date. If you have not updated - it recently, you need to run emerge sync before anything else. This - way, you will be using the most recent stable version of Apache and - PHP. - - Now that everything is in place, you can use the following example to - install Apache and PHP: - - Example 3-1. Gentoo Install Example with Apache 1.3 -# emerge \<apache-2 -# USE="-*" emerge php mod_php -# ebuild /var/db/pkg/dev-php/mod_php-<your PHP version>/mod_php-<your PHP versi -on>.ebuild config -# nano /etc/conf.d/apache - Add "-D PHP4" to APACHE_OPTS - -# rc-update add apache default -# /etc/init.d/apache start - - You can read more about emerge in the excellent Portage Manual - provided on the Gentoo website. - - If you need to use Apache 2, you can simply use emerge apache in the - last example. - _________________________________________________________________ - -Better control on configuration - - In the last section, PHP was emerged without any activated modules. As - of this writing, the only module activated by default with Portage is - XML which is needed by PEAR. This may not be what you want and you - will soon discover that you need more activated modules, like MySQL, - gettext, GD, etc. - - When you compile PHP from source yourself, you need to activate - modules via the configure command. With Gentoo, you can simply provide - USE flags which will be passed to the configure script automatically. - To see which USE flags to use with emerge, you can try: - - Example 3-2. Getting the list of valid USE flags -# USE="-*" emerge -pv php - -[ebuild N ] dev-php/php-4.3.6-r1 -X -berkdb -crypt -curl -debug -doc --fdftk -firebird -flash -freetds -gd -gd-external -gdbm -gmp -hardenedphp --imap -informix -ipv6 -java -jpeg -kerberos -ldap -mcal -memlimit -mssql --mysql -ncurses -nls -oci8 -odbc -pam -pdflib -png -postgres -qt -readline --snmp -spell -ssl -tiff -truetype -xml2 -yaz 3,876 kB - - As you can see from the last output, PHP considers a lot of USE flags. - Look at them closely and choose what you need. If you choose a flag - and you do not have the proper librairies, Portage will compile them - for you. It is a good idea to use emerge -pv again to see what Portage - will compile in accordance to your USE flags. As an example, if you do - not have X installed and you choose to include X in the USE flags, - Portage will compile X prior to PHP, which can take a couple of hours. - - If you choose to compile PHP with MySQL, cURL and GD support, the - command will look something like this: - - Example 3-3. Install PHP with USE flags - # USE="-* curl mysql gd" emerge php mod_php - - As in the last example, do not forget to emerge php as well as - mod_php. php is responsible for the command line version of PHP as - mod_php is for the Apache module version of PHP. - _________________________________________________________________ - -Common Problems - - * If you see the PHP source instead of the result the script should - produce, you have probably forgot to edit /etc/conf.d/apache. - Apache needs to be started with the -D PHP4 flag. To see if the - flag is present, you should be able to see it when using ps ax | - grep apache while Apache is running. - * Due to slotting problems, you might end up with more than one - version of PHP installed on your system. If this is the case, you - need to unmerge the old versions manually by using emerge unmerge - mod_php-<old version>. - * If you cannot emerge PHP because of Java, try putting -* in front - of your USE flags like in the above examples. - * If you are having problems configuring Apache and PHP, you can - always search the Gentoo Forums. Try searching with the keywords - "Apache PHP". - _________________________________________________________________ - -HP-UX specific installation notes - - This section contains notes and hints specific to installing PHP on - HP-UX systems.

You now need bison, you can download a binary distribution from - http://hpux.connect.org.uk/ftp/hpux/Gnu/bison-1.28/bison-1.28-sd-1 - 0.20.depot.gz, install as above. - 5. You now need flex, you need to download the source from one of the - http://www.gnu.org mirrors. It is in the non-gnu directory of the - ftp site. Download the file, gunzip, then tar -xvf it. Go into the - newly created flex directory and run ./configure, followed by - make, and then make install. - If you have errors here, it's probably because gcc etc. are not in - your PATH so add them to your PATH. - 6. Download the PHP and apache sources. - 7. gunzip and tar -xvf them. We need to hack a couple of files so - that they can compile OK. - 8. Firstly the configure file needs to be hacked because it seems to - lose track of the fact that you are a hpux machine, there will be - a better way of doing this but a cheap and cheerful hack is to put - lt_target=hpux10.20 on line 47286 of the configure script. - 9. Next, the Apache GuessOS file needs to be hacked. Under - apache_1.3.9/src/helpers change line 89 from echo - "hp${HPUXMACH}-hpux${HPUXVER}"; exit 0 to: echo - "hp${HPUXMACH}-hp-hpux${HPUXVER}"; exit 0 - 10. You cannot install PHP as a shared object under HP-UX so you must - compile it as a static, just follow the instructions at the Apache - page. - 11. PHP and Apache should have compiled OK, but Apache won't start. - you need to create a new user for Apache, e.g. www, or apache. You - then change lines 252 and 253 of the conf/httpd.conf in Apache so - that instead of - -User nobody -Group nogroup - - you have something like - -User www -Group sys - - This is because you can't run Apache as nobody under hp-ux. Apache - and PHP should then work. - _________________________________________________________________ - -OpenBSD installation notes - - This section contains notes and hints specific to installing PHP on - OpenBSD 3.4. - _________________________________________________________________ - -Using Binary Packages - - Using binary packages to install PHP on OpenBSD is the recommended and - simplest method. The core package has been separated from the various - modules, and each can be installed and removed independently from the - others. The files you need can be found on your OpenBSD CD or on the - FTP site. - - The main package you need to install is php4-core-4.3.3.tgz, which - contains the basic engine (plus gettext and iconv). Next, take a look - at the module packages, such as php4-mysql-4.3.3.tgz or - php4-imap-4.3.3.tgz. You need to use the phpxs command to activate and - deactivate these modules in your php.ini. - - Example 3-4. OpenBSD Package Install Example -# pkg_add php4-core-4.3.3.tgz -# /usr/local/sbin/phpxs -s -# cp /usr/local/share/doc/php4/php.ini-recommended /var/www/conf/php.ini - (add in mysql) -# pkg_add php4-mysql-4.3.3.tgz -# /usr/local/sbin/phpxs -a mysql - (add in imap) -# pkg_add php4-imap-4.3.3.tgz -# /usr/local/sbin/phpxs -a imap - (remove mysql as a test) -# pkg_delete php4-mysql-4.3.3 -# /usr/local/sbin/phpxs -r mysql - (install the PEAR libraries) -# pkg_add php4-pear-4.3.3.tgz - - Read the packages(7) manual page for more information about binary - packages on OpenBSD. - _________________________________________________________________ - -Using Ports - - You can also compile up PHP from source using the ports tree. However, - this is only recommended for users familiar with OpenBSD. The PHP 4 - port is split into two sub-directories: core and extensions. The - extensions directory generates sub-packages for all of the supported - PHP modules. If you find you do not want to create some of these - modules, use the no_* FLAVOR. For example, to skip building the imap - module, set the FLAVOR to no_imap. - _________________________________________________________________ - -Common Problems - - * The default install of Apache runs inside a chroot(2) jail, which - will restrict PHP scripts to accessing files under /var/www. You - will therefore need to create a /var/www/tmp directory for PHP - session files to be stored, or use an alternative session backend. - In addition, database sockets need to be placed inside the jail or - listen on the localhost interface. If you use network functions, - some files from /etc such as /etc/resolv.conf and /etc/services - will need to be moved into /var/www/etc. The OpenBSD PEAR package - automatically installs into the correct chroot directories, so no - special modification is needed there. More information on the - OpenBSD Apache is available in the OpenBSD FAQ. - * The OpenBSD 3.4 package for the gd extension requires XFree86 to - be installed. If you do not wish to use some of the font features - that require X11, install the php4-gd-4.3.3-no_x11.tgz package - instead. - _________________________________________________________________ - -Older Releases - - Older releases of OpenBSD used the FLAVORS system to compile up a - statically linked PHP. Since it is hard to generate binary packages - using this method, it is now deprecated. You can still use the old - stable ports trees if you wish, but they are unsupported by the - OpenBSD team. If you have any comments about this, the current - maintainer for the port is Anil Madhavapeddy (avsm at openbsd dot - org). - _________________________________________________________________ - -Solaris specific installation tips - - This section contains notes and hints specific to installing PHP on - Solaris systems. - _________________________________________________________________ - -Required software - - Solaris installs often lack C compilers and their related tools.

The required software is as follows: - - * gcc (recommended, other C compilers may work) - * make - * flex - * bison - * m4 - * autoconf - * automake - * perl - * gzip - * tar - * GNU sed - - In addition, you will need to install (and possibly compile) any - additional software specific to your configuration, such as Oracle or - MySQL. - _________________________________________________________________ - -Using Packages - - You can simplify the Solaris install process by using pkgadd to - install most of your needed components. - _________________________________________________________________ - Apache 1.3.x on Unix systems This section contains notes and hints specific to Apache installs of @@ -546,7 +155,7 @@ Apache 1.3.x on Unix systems You will need to replace the 'xxx' here with the correct values from your files. - Example 3-5.

The required software is as follows: + + * gcc (recommended, other C compilers may work) + * make + * flex + * bison + * m4 + * autoconf + * automake + * perl + * gzip + * tar + * GNU sed + + In addition, you will need to install (and possibly compile) any + additional software specific to your configuration, such as Oracle or + MySQL. + _________________________________________________________________ + +Using Packages + + You can simplify the Solaris install process by using pkgadd to + install most of your needed components. + _________________________________________________________________ + +Gentoo installation notes + + This section contains notes and hints specific to installing PHP on + Gentoo Linux. + _________________________________________________________________ + +Using Portage (emerge) + + While you can just download the PHP source and compile it yourself, + using Gentoo's packaging system is the simplest and cleanest method of + installing PHP. If you are not familiar with building software on + Linux, this is the way to go. + + If you have built your Gentoo system so far, you are probably used to + Portage already. Installing Apache and PHP is no different than the + other system tools. + + The first decision you need to make is whether you want to install + Apache 1.3.x or Apache 2.x. While both can be used with PHP, the steps + given bellow will use Apache 1.3.x. Another thing to consider is + whether your local Portage tree is up to date. If you have not updated + it recently, you need to run emerge sync before anything else. This + way, you will be using the most recent stable version of Apache and + PHP. + + Now that everything is in place, you can use the following example to + install Apache and PHP: + + Example 2-7. Gentoo Install Example with Apache 1.3 +# emerge \<apache-2 +# USE="-*" emerge php mod_php +# ebuild /var/db/pkg/dev-php/mod_php-<your PHP version>/mod_php-<your PHP versi +on>.ebuild config +# nano /etc/conf.d/apache + Add "-D PHP4" to APACHE_OPTS + +# rc-update add apache default +# /etc/init.d/apache start + + You can read more about emerge in the excellent Portage Manual + provided on the Gentoo website. + + If you need to use Apache 2, you can simply use emerge apache in the + last example. + _________________________________________________________________ + +Better control on configuration + + In the last section, PHP was emerged without any activated modules. As + of this writing, the only module activated by default with Portage is + XML which is needed by PEAR. This may not be what you want and you + will soon discover that you need more activated modules, like MySQL, + gettext, GD, etc. + + When you compile PHP from source yourself, you need to activate + modules via the configure command. With Gentoo, you can simply provide + USE flags which will be passed to the configure script automatically. + To see which USE flags to use with emerge, you can try: + + Example 2-8. Getting the list of valid USE flags +# USE="-*" emerge -pv php + +[ebuild N ] dev-php/php-4.3.6-r1 -X -berkdb -crypt -curl -debug -doc +-fdftk -firebird -flash -freetds -gd -gd-external -gdbm -gmp -hardenedphp +-imap -informix -ipv6 -java -jpeg -kerberos -ldap -mcal -memlimit -mssql +-mysql -ncurses -nls -oci8 -odbc -pam -pdflib -png -postgres -qt -readline +-snmp -spell -ssl -tiff -truetype -xml2 -yaz 3,876 kB + + As you can see from the last output, PHP considers a lot of USE flags. + Look at them closely and choose what you need. If you choose a flag + and you do not have the proper libraries, Portage will compile them + for you. It is a good idea to use emerge -pv again to see what Portage + will compile in accordance to your USE flags. As an example, if you do + not have X installed and you choose to include X in the USE flags, + Portage will compile X prior to PHP, which can take a couple of hours. + + If you choose to compile PHP with MySQL, cURL and GD support, the + command will look something like this: + + Example 2-9. Install PHP with USE flags + # USE="-* curl mysql gd" emerge php mod_php + + As in the last example, do not forget to emerge php as well as + mod_php. php is responsible for the command line version of PHP as + mod_php is for the Apache module version of PHP. + _________________________________________________________________ + +Common Problems + + * If you see the PHP source instead of the result the script should + produce, you have probably forgot to edit /etc/conf.d/apache. + Apache needs to be started with the -D PHP4 flag. To see if the + flag is present, you should be able to see it when using ps ax | + grep apache while Apache is running. + * Due to slotting problems, you might end up with more than one + version of PHP installed on your system. If this is the case, you + need to unmerge the old versions manually by using emerge unmerge + mod_php-<old version>. + * If you cannot emerge PHP because of Java, try putting -* in front + of your USE flags like in the above examples. + * If you are having problems configuring Apache and PHP, you can + always search the Gentoo Forums. Try searching with the keywords + "Apache PHP". + _________________________________________________________________ + +Chapter 3. Installation on Mac OS X + + This section contains notes and hints specific to installing PHP on + Mac OS X. There are two slightly different versions of Mac OS X, + Client and Server, our manual deals with installing PHP on both + systems. Note that PHP is not available for MacOS 9 and earlier + versions. + _________________________________________________________________ + +Using Packages + + There are a few pre-packaged and pre-compiled versions of PHP for Mac + OS X. This can help in setting up a standard configuration, but if you + need to have a different set of features (such as a secure server, or + a different database driver), you may need to build PHP and/or your + web server yourself. If you are unfamiliar with building and compiling + your own software, it's worth checking whether somebody has already + built a packaged version of PHP with the features you need. + _________________________________________________________________ + +Compiling for OS X Server + + Mac OS X Server install. + + 1. Get the latest distributions of Apache and PHP. + 2. Untar them, and run the configure program on Apache like so. + +./configure --exec-prefix=/usr \ +--localstatedir=/var \ +--mandir=/usr/share/man \ +--libexecdir=/System/Library/Apache/Modules \ +--iconsdir=/System/Library/Apache/Icons \ +--includedir=/System/Library/Frameworks/Apache.framework/Versions/1.3/Headers \ +--enable-shared=max \ +--enable-module=most \ +--target=apache + + 3. If you want the compiler to do some optimization, you may also + want to add this line: + +setenv OPTIM=-O2 + + 4. Next, go to the PHP 4 source directory and configure it. + +./configure --prefix=/usr \ + --sysconfdir=/etc \ + --localstatedir=/var \ + --mandir=/usr/share/man \ + --with-xml \ + --with-apache=/src/apache_1.3.12 + + If you have any other additions (MySQL, GD, etc.), be sure to add + them here. For the --with-apache string, put in the path to your + apache source directory, for example /src/apache_1.3.12. + 5. Type make and make install. This will add a directory to your + Apache source directory under src/modules/php4. + 6. Now, reconfigure Apache to build in PHP 4. + +./configure --exec-prefix=/usr \ +--localstatedir=/var \ +--mandir=/usr/share/man \ +--libexecdir=/System/Library/Apache/Modules \ +--iconsdir=/System/Library/Apache/Icons \ +--includedir=/System/Library/Frameworks/Apache.framework/Versions/1.3/Headers \ +--enable-shared=max \ +--enable-module=most \ +--target=apache \ +--activate-module=src/modules/php4/libphp4.a + + You may get a message telling you that libmodphp4.a is out of + date. If so, go to the src/modules/php4 directory inside your + Apache source directory and run this command: ranlib libmodphp4.a. + Then go back to the root of the Apache source directory and run + the above configure command again. That'll bring the link table up + to date. Run make and make install again. + 7. Copy and rename the php.ini-dist file to your bin directory from + your PHP 4 source directory: cp php.ini-dist + /usr/local/bin/php.ini or (if your don't have a local directory) + cp php.ini-dist /usr/bin/php.ini. + _________________________________________________________________ + +Compiling for MacOS X Client + + The following instructions will help you install a PHP module for the + Apache web server included in MacOS X. This version includes support + for the MySQL and PostgreSQL databases. These instructions are + graciously provided by Marc Liyanage. + + Warning + + Be careful when you do this, you could screw up your Apache web + server! + + Do this to install: + + 1. Open a terminal window. + 2. Type wget + http://www.diax.ch/users/liyanage/software/macosx/libphp4.so.gz, + wait for the download to finish. + 3. Type gunzip libphp4.so.gz. + 4. Type sudo apxs -i -a -n php4 libphp4.so + 5. Now type sudo open -a TextEdit /etc/httpd/httpd.conf. TextEdit + will open with the web server configuration file. Locate these two + lines towards the end of the file: (Use the Find command) + +#AddType application/x-httpd-php .php +#AddType application/x-httpd-php-source .phps + + Remove the two hash marks (#), then save the file and quit + TextEdit. + 6. Finally, type sudo apachectl graceful to restart the web server. + + PHP should now be up and running. You can test it by dropping a file + into your Sites folder which is called test.php. Into that file, write + this line: <?php phpinfo() ?>. + + Now open up 127.0.0.1/~your_username/test.php in your web browser. You + should see a status table with information about the PHP module. + _________________________________________________________________ + +Chapter 4. Installation of PECL extensions + +Introduction to PECL Installations + + PHP extensions may be installed in a variety of ways. PECL is a + repository of PHP extensions living within the PEAR structure, and the + following demonstrates how to install these extensions. + + These instructions assume /your/phpsrcdir/ is the path to the PHP + source, and extname is the name of the PECL extension. Adjust + accordingly. These instructions also assume a familiarity with the + pear command. + + Shared extensions may be installed by including them inside of php.ini + using the extension PHP directive. See also the extensions_dir + directive, and dl(). The installation methods described below do not + automatically configure PHP to include these extensions, this step + must be done manually. + + When building PHP modules, it's important to have the appropriate + versions of the required tools (autoconf, automake, libtool, etc.) See + the Anonymous CVS Instructions for details on the required tools, and + required versions. + _________________________________________________________________ + +Downloading PECL extensions + + There are several options for downloading PECL extensions, such as: + + * http://pecl.php.net + Listed here is information like the ChangeLog, release + information, requirements, revisions, etc. Although not every PECL + extension has a webpage, most do. + * pear download extname + The pear command may also be used to download source files. + Specific revisions may also be specified. + * CVS + All PECL files reside in CVS. A web-based view may be seen at + http://cvs.php.net/pecl/. To download straight from CVS, consider + the following where phpfi is the password for user cvsread: + +$ cvs -d:pserver:cvsread@cvs.php.net:/repository login +$ cvs -d:pserver:cvsread@cvs.php.net:/repository co pecl/extname + + * Windows downloads + Windows users may find compiled PECL binaries by downloading the + Collection of PECL modules from the PHP Downloads page, and by + retrieving a PECL Snapshot. To compile PHP under Windows, read the + Win32 Build README. + _________________________________________________________________ + +PECL for Windows users + + Like with any other PHP extension DLL, to install move the PECL + extension DLLs into the extension_dir folder and include them within + php.ini. For example: + + extension=php_extname.dll + + After doing this, restart the web server. + _________________________________________________________________ + +Compiling shared PECL extensions with PEAR + + PEAR makes it easy to create shared PHP extensions. Using the pear + command, do the following: + + $ pear install extname + + That will download the source for extname, and compile it on the + system. This results in an extname.so file that may then be included + in php.ini + + In case the systems preferred_state is set higher than an available + extname version, like it's set to stable and the extension is still in + beta, either alter the preferred_state via pear config-set or specify + a specific version of the PECL extension. For example: + + $ pear install extname-0.1.1 + + Regardless, pear will copy this extname.so into the extensions + directory. Adjust php.ini accordingly. + _________________________________________________________________ + +Compiling shared PECL extensions with phpize + + If using pear is not an option, like for building shared PECL + extensions from CVS, or for unreleased PECL packages, then creating a + shared extension may also be done by manually using the phpize + command. The pear command essentially does this but it may also be + done manually. Assuming the source file is named extname.tgz, and that + it was downloaded into the current directory, consider the following: + +$ pear download extname +$ gzip -d < extname.tgz | tar -xvf - +$ cd extname +$ phpize +$ ./configure && make + + Upon success, this will create extname.so and put it into the modules/ + and/or .libs/ directory within the extname/ source. Move this shared + extension (extname.so) into the PHP extensions directory, and adjust + php.ini accordingly. + _________________________________________________________________ + +Compiling PECL extensions statically into PHP + + To statically include the extension within the PHP build, put the + extensions source into the ext/ directory found in the PHP source. For + example: + +$ cd /your/phpsrcdir/ext +$ pear download extname +$ gzip -d < extname.tgz | tar -xvf - +$ mv extname-x.x.x extname +$ rm package.xml + + This will result in the following directory: + + /your/phpsrcdir/ext/extname + + From here, build PHP as normal: + +$ cd /your/phpsrcdir +$ ./buildconf +$ ./configure --help +$ ./configure --with-extname --enable-someotherext --with-foobar +$ make +$ make install + + Whether --enable-extname or --with-extname is used depends on the + extension. Typically an extension that does not require external + libraries uses --enable. To be sure, run the following after + buildconf: + + $ ./configure --help | grep extname + _________________________________________________________________ + +Chapter 5. Problems?
