Default New httpd and PHP

Is someone knows how to setup PHP with the new httpd web server on OpenBSD 5.6?

It's really boring how there's is no documentation for this new webserver... The man page says nothing about PHP and the example httpd.conf file is very incomplete not showing all commented (#) availables options.

Why the developper doesn't give all availables options in the example conf file?

So I want to setup PHP with this server. Anyone knows how to?

See /etc/examples/httpd.conf for an example that uses php-fpm.

Reyk Flöter presented this slide deck at AsiaBSDCon 2015. (Related paper.).

It not only covers the development of the FastCGI interface used by php-fpm, mentioned above, but may be of general interest to OpenBSD users, as it discusses the history of all of the webservers that have been included in the base, and gives clear reasoning for the removal of nginx from base.

Here is how I got it going:
I had to install the php-fpm package.
I restarted httpd
I started fpm with
Code:
/etc/rc.d/php_fpm start
If I understand correctly, in order to start after reboot I need to have this in my rc.conf.local file:
Code:
pkg_scripts="php_fpm"
I hope that helps.

Default OpenBSD-5.7

The default /etc/php-fpm.conf doesn't seem to be adequate to start the service.

$ sudo php-fpm-5.6
Code:
                                                              
[17-Aug-2015 12:16:30] ALERT: [pool www] user has not been defined
[17-Aug-2015 12:16:30] ERROR: failed to post process the configuration
[17-Aug-2015 12:16:30] ERROR: FPM initialization failed
Is anyone willing to post their php config files?

Also, I didn't know what might be needed during my PHP dev explorations so I installed everything. Are there any conflicts or contradictions in here?

$ pkg_info | grep php

I use php-fpm with nginx, but the settings should be similar. I'll dig through my configuration files when I'm out from behind $DAYJOB's Great Corporate Firewall (tm).

Meanwhile, I note there was a -stable update to php 5.6 which affecting this configuration file, and it was committed on May 18. You'll want the -stable php 5.6, as it may resolve your problem.

(My system running php with nginx is 5.7-stable/i386.)

The system I am working with is also a 5.7-stable/i386. PHP was installed with pkg_add.
$ echo $PKG_PATH
Code:
ftp://ftp.openbsd.org/pub/OpenBSD/5.7/packages/i386/
Does PHP need to be built from an updated /usr/ports tree to get the -stable version? That should only take a day or two Updating src, ports, and xenocara now. Will build all tonight and take another crack at configuring PHP tomorrow. Looking forward to seeing your config

You'll note the date on that package is May 9, which predates the commit. The Project does not build -stable packages; we -stable users must build them ourselves or use M:Tier's services.

Here is the -stable php-fpm.conf file, with the bazillion comments removed:
Code:
[global]
[www]
user = www
group = www
listen = /var/www/run/php-fpm.sock
listen.owner = www
listen.group = www
listen.mode = 0660
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
chroot = /var/www
Here is my php-fpm.conf file, with the bazillion comments removed. The only difference from the default is I am using the loopback address rather than a filesystem TCP socket, so I have a different listen value, and I do not use the listen.* filesystem options.

I'm using the loopback NIC for historical reasons -- the nginx webserver and the PHP application server used to be on separate systems.
Code:
[global]
[www]
user = www
group = www
listen = 127.0.0.1:9000
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
chroot = /var/www
Comparing the -stable and -release versions of /usr/local/share/examples/php5.6/php-fpm.conf, the only differences I note are in the comments.

Thanks, jggimi! The recent 5.7-stable version (php-fpm-5.6.10) starts and works just fine with the default conf file settings.

This might be a resources issue. Here's my test setup (unbound resolves names):

/etc/httpd.conf
Code:
prefork 1

server "lucidrine.bohemia.net" {
        listen on 192.168.0.1 port 80

        directory { no auto index, index "index.php" }

        location "*.php" {
                fastcgi socket "/run/php-fpm.sock"
        }

        root "/htdocs/lucidrine.bohemia.net"
}
/var/www/htdocs/lucidrine.bohemia.net/index.php
Code:
<!DOCTYPE html>
<html>
  <head>
         <title>Test</title>
  </head>
  <body>
        <?php
                echo "<h1>Hello World!</h1>";
                phpinfo(); 
        ?>
  </body>
</html>
$ curl http://lucidrine.bohemia.net/
Code:
curl: (52) Empty reply from server
/var/log/php-fpm.log
Code:
[19-Aug-2015 16:05:54] NOTICE: fpm is running, pid 7052

Is there a tuning guide anywhere? The default settings don't seem to utilize the machine's resources and sometimes programs seem to hit the limit and either fail to start or coredump.

$ top
Code:

Edit2: It works without the phpinfo() function.

I just did this in a virtual machine, using your httpd.conf and index.php, and was successful. I used i386-stable, and the -stable packages I'd built. However, I used php 5.5, not 5.6.

If I recall correctly, I'm on 5.5 because of a php-<something> sub package dependency which was not available with 5.6.

If it's a resource issue, is there a way to coax OpenBSD into using more of what's available? I haven't found a decent explanation of how to do that (yet). The defaults seem to assume a very limited machine. Often, programs seem to hit that very low ceiling. Any doc pointers and maybe suggestions for conf files? (jeez, does it sound like I'm getting lazy? )

I just built 5.6.10 on my i386-stable build machine, and installed it in the -stable virtual machine. I cannot reproduce your problem.

This was a 5.7-stable installation. The only changes from default install were the addition of your httpd.conf (with an address on my local network) , your index.php, and an /etc/rc.conf.local file containing only:
Code:
http_flags=
pkg_scripts=php_fpm
The browser was tested against the listening IP address, so DNS was not involved.

It's a default Qemu virtual machine, with 128MB of virtual RAM, with virtio(4) drivers used for storage and for network interconnect. I ran the network in tap mode, so the virtual machine is on the local network and I could reach it from my browser. The vlan2 NIC is the local subnet.
Code:
sudo ifconfig tun0 link0
sudo ifconfig bridge0 add tun0 add vlan2 up

sudo sh -c "qemu-system-i386 -runas $USER \
-nographic \
-net nic,model=virtio -net tap \
-drive file=i386.img,if=virtio,format=raw"
You are getting SIGSEGV - segmentation violations. This doesn't appear to be resources. I suspect a misconfiguration of software of some kind. Double check libraries. Here's the output from $ ldd /usr/local/sbin/php-fpm-5.6 on that functioning -stable test system. Do you have the same levels of libraries in yours?

OK, then I'm at a loss to explain the errors, as the libraries match. And, since I can't replicate the error, I can't help with debugging it.

According to signal(3), SIGSEGV should create a core(5) image. There may be .core files available.

Success, httpd returns the phpinfo page!

Hmm, so what's wrong with php-tidy-5.6.10? Or what did I do wrong?

Well, I installed php-tidy, and still could not replicate the failure. And ldd(1) shows tidy was built with libpthread.so.18.1. I'll assume yours was too, but before digging through .core files with gdb(1), you might double-check that.

I always double-check libraries ... probably because mismatches are a common thing to check when running -current. (I run -current on workstations, where I only keep -stable for building.)

Many of the installed packages are probably out of date with the current ports. I guess the problem has to do with that. Is there a canonical way to update (build from ports) all installed packages after each src,xenocara,ports update?

Wrong tidy. That's a binary from www/tidyp. I know, because I have databases/pkglocatedb installed.
Code:
$ pkglocate bin/tidy
tidyp-1.04p1v0:www/tidyp:/usr/local/bin/tidy
tidyp-1.04p1v0:www/tidyp:/usr/local/bin/tidyp
$
Here's what I know about the php-tidy I installed:
Code:
$ pkg_info -L php-tidy
Information for inst:php-tidy-5.6.10

Files:
/usr/local/lib/php-5.6/modules/tidy.so
/usr/local/share/examples/php-5.6/tidy.ini


$ ldd /usr/local/lib/php-5.6/modules/tidy.so
/usr/local/lib/php-5.6/modules/tidy.so:
    Start     End      Type Open Ref GrpRef Name
    09bf5000 29bfa000 dlib 1    0    0      /usr/local/lib/php-5.6/modules/tidy.so
