PHP-FPM 8.0 on OpenBSD 7.0

( modified )



PHP-FPM, PHP FastCGI Process Manager, is a part of PHP package in OpenBSD packages nowadays. So installing PHP (php-?.? due to the version) comes with php??_fpm automatically 💃 This post will show you how to set it up.


  • OS: OpenBSD 7.0 amd64
  • PHP: 8.0

The first step is to install the PHP package:

$ doas pkg_add php
Ambiguous: choose package for php
a	0: <None>
	1: php-7.3.33
	2: php-7.4.27
	3: php-8.0.14
Your choice:

I chose “3” because it’s longer supported term due to each support term of the PHP versions.

The output was:

php-8.0.14:femail-1.0p1: ok
php-8.0.14:femail-chroot-1.0p3: ok
php-8.0.14:argon2-20190702: ok
php-8.0.14:libsodium-1.0.18p1: ok
php-8.0.14:libxml-2.9.12: ok
php-8.0.14:oniguruma- ok
php-8.0.14: ok
Running tags: ok
The following new rcscripts were installed: /etc/rc.d/php80_fpm
See rcctl(8) for details.
New and changed readme(s):

Then these directories/files were made:

$ ls /etc/php*
/etc/php-8.0.ini  /etc/php-fpm.conf




Well, the .ini file(s) in /etc/php-8.0.sample are PHP extensions. According to necessity, copy each of them to /etc/php-8.0/ to activate the extensions:

$ doas ln -sf /etc/php-8.0.sample/%target-ini-files% /etc/php-8.0/

Also edit /etc/php-8.0.ini as needed. For example:

  ; Maximum allowed size for uploaded files.
- upload_max_filesize = 2M
+ upload_max_filesize = 5M

Besides, the manual is also installed as /usr/local/share/doc/pkg-readmes/php-8.0 which declares:

The main OpenBSD php packages include php-fpm, FastCGI Process Manager. This manages pools of FastCGI processes: starts/restarts them and maintains a minimum and maximum number of spare processes as configured. You can use rcctl(8) to enable php-fpm at boot, and start it at runtime:

rcctl enable php80_fpm
rcctl start php80_fpm

OK. We’re ready. Let’s start daemon:

$ doas rcctl enable php80_fpm

It appended a line to /etc/rc.conf.local:

+ pkg_scripts=php80_fpm

OK. It’s time to start the daemon:

$ doas rcctl start php80_fpm


Next, we need to prepare a web server. Let’s edit /etc/httpd.conf to add fastcgi socket in SERVERS sections like this:

types {
    include "/usr/share/misc/mime.types"


server "default" {
    listen on $ext_addr port 80

    root "/htdocs"
    directory index index.php

    location "/*.php" { 
        fastcgi socket "/run/php-fpm.sock"
    location "/*.php[/?]*" { 
        fastcgi socket "/run/php-fpm.sock"

Note that chroot works in this context. Therefore, fastcgi socket "/run/php-fpm.sock" in /etc/httpd.conf actually means fastcgi socket "/var/www/run/php-fpm.sock". This is the same to that root "/htdocs" means "/var/www/htdocs".


Let’s make /var/www/htdocs/index.php for testing like this:

# echo "<?php phpinfo(); ?>" > /var/www/htdocs/index.php
# # delete the file above afterwards as needed

Then browsing your host will show you the whole phpinfo!
