This section contains notes and hints specific to installing PHP on » OpenBSD.
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 php, which contains the basic engine (plus fpm, gettext and iconv) and might be available in several versions to choose from. Next, take a look at the module packages, such as php-mysqli or php-imap. You need to use the phpxs command to activate and deactivate these modules in your php.ini.
Example #1 OpenBSD Package Install Example
# pkg_add php # pkg_add php-apache # pkg_add php-mysqli (install the PEAR libraries) # pkg_add pear Follow the instructions shown with each package! (to remove packages) # pkg_delete php # pkg_delete php-apache # pkg_delete php-mysqli # pkg_delete pear
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 port is split into core and extensions. The extensions generate 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.
UPDATE: OpenBSD 6.9:
- The package "php-fpm" no longer exists. It's the default, so you can just install "php".
- The /var/www/tmp directory will be created automatically when you install PHP.
- PHP 8 is available :D as well as older versions. pkg_add will ask you which version to install.A brief update: As of OpenBSD 5.7 (2015) the installation process is extremely easy. Apache httpd was replaced by Nginx, which has since been further replaced by OpenBSD's own server, aptly named 'httpd'.
'httpd' is installed by default, everything else you can still get from packages, with a couple name changes (including Apache and Nginx.) You will be asked which version to install - at the time of writing, versions 5.3.29p1 thru 5.6.5 are available.
#pkg_add php
#pkg_add php-fpm
#pkg_add pear
----
OpenBSD disables most services by default; a blank '_flags' line overrides default 'NO' value. pkg_scripts are located in /etc/rc.d/
To start at boot, edit "/etc/rc.conf.local":
httpd_flags=
pkg_scripts=php_fpm
----
Example /etc/httpd.conf
#
# paths are relative to chroot - e.g, '/var/www/run/php-fpm.sock'
server "default" {
listen on * port 80
location "*.php" {
fastcgi socket "/run/php-fpm.sock"
}
directory index index.php
root "/htdocs"
}
----
For date, timezone issues, copy /etc/localtime:
$cp /etc/localtime /var/www/etc/localtime
If 'localhost' DNS name fails to resolve, copy /etc/hosts
$cp /etc/hosts /var/www/etc/hostsI just finished spinning my wheels with PHP/Apache on OpenBSD 3.3, and it took a Google to fix my problem. I followed the instructions by (0429196301 at netcabo dot pt) written on Sep 19, 2003 and kept being fed a segmentation fault when I tried to start httpd.
Then I read the page cited below that suggested playing with the order of the LoadModules, and put the PHP first. I followed that recommendation and httpd started without problems!
Page that saved me:

"Change around the order of the Apache modules, this is one of the
drawbacks to the module API for Apache 1.3 is that the order is very
important. I would try making the PHP 4 module first, Perl module second
and FP module last. "I am user that is just migrating to open source and thought I would take openbsd for a spin. This article, by Gregory L. Magnusson, really helped me to get a working apache-php-mysql server going on openbsd.
http://www.devx.com/security/Article/28059/0/page/1On OpenBSD 3.2, given the steps outlined above using pre-built packages you will get a new "/var/www/conf/httpd.conf" that contains a section like this:
<IfDefine SSL>
AddModule mod_ssl.c
AddModule mod_php4.c
</IfDefine>
This causes mod_php4 to load only when starting Apache w/SSL, so if this isn't what you want add the mod_php4 line again above (or below) this section, like so:
AddModule mod_php4.c <<------ SEE? - now should load normally.
<IfDefine SSL>
AddModule mod_ssl.c
AddModule mod_php4.c
</IfDefine>
I also added this for good measure:
<IfModule mod_php4.c>
AddType application/x-httpd-php .php [blah blah]
</IfModule>
Seems to work.Also you should add "-a /var/www/dev/log" to the syslogd_flags
for propper logging of php-extensions like imap.so and create
a /var/www/etc/master.passwd with an www-user-entry and run
pwd_mkdb -d /var/www/etc /var/www/etc/master.passwd for propper
use of libc-client.a functions in imap.so.
