This section contains notes and hints specific to installing PHP on » OpenBSD 3.6.
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
which contains the basic engine (plus gettext and iconv). Next, take a look
at the module packages, such as
php4-imap-4.3.8.tgz. You need to use the phpxs
command to activate and deactivate these modules in your
# pkg_add php4-core-4.3.8.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-4.3.8.tgz
# /usr/local/sbin/phpxs -a mysql
(add in imap)
# pkg_add php4-imap-4.3.8.tgz
# /usr/local/sbin/phpxs -a imap
(remove mysql as a test)
# pkg_delete php4-mysql-4.3.8
# /usr/local/sbin/phpxs -r mysql
(install the PEAR libraries)
# pkg_add php4-pear-4.3.8.tgz
Read the » packages(7) manual page for more information about binary packages on OpenBSD.
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.
/var/www. You will therefore need to create a
/var/www/tmpdirectory 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
localhostinterface. If you use network functions, some files from
/etc/serviceswill 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.
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).
