mini_httpd + PHP is an easy way to write a web app with root access.

Install mini_httpd

cd /usr/ports/www/mini_httpd
make install clean

Install php

To use PHP with mini_httpd, you need to fix an outstanding PHP bug #28227 with a patch by Luke Mewburn.

cd /usr/ports/lang/php4
make fetch
cd /tmp
tar xyf /usr/ports/distfiles/php-4.4.2.tar.bz2
cd php-4.4.2
fetch http://tomclegg.net/software/patch-php4-script_filename
patch <patch-php4-script_filename
./configure --prefix=/usr/local/php-cgi
mkdir /usr/local/php-cgi
make install

Install daemontools

cd /usr/ports/sysutils/daemontools
make install clean
echo >>/etc/rc.conf 'svscan_enable="YES"'
echo >>/etc/rc.conf 'svscan_servicedir="/service"'
mkdir /service /var/service
/usr/local/etc/rc.d/svscan.sh start

Set up a supervised mini_httpd service

In this example, mini_httpd will listen on port 808. Change the port number to suit.

cd /var/service
mkdir mini_httpd
cd mini_httpd
chmod +t .
mkdir root log log/main
cat <<EOF >run
#!/bin/sh
exec \
 env - PATH=/bin:/sbin:/usr/bin:/usr/sbin:\
/usr/local/bin:/usr/local/sbin:/var/qmail/bin \
 mini_httpd -D -p 808 -u root -d root/ -c '**.php|**.cgi' 2>&1
EOF

cat <<EOF >log/run
#!/bin/sh
exec multilog t ./main/
EOF

cat <<EOF >root/index.php
#!/usr/local/php-cgi/bin/php
<? echo "ok"; ?>
EOF

chmod +x run log/run root/index.php
chmod 700 .

Start the mini_httpd service

cd /service
ln -s /var/service/mini_httpd

sleep 6
svstat /service/mini_httpd
sockstat | grep mini_httpd

Install your web app

Your web files go in /var/service/mini_httpd/root/. If you don't like it, remove that directory and replace it with a symlink to your preferred location.

Files ending in .cgi or .php are expected to be CGI programs. PHP programs should have #!/usr/local/php-cgi/bin/php on the first line. PHP (and other) programs must be executable.

Your web app runs at http://your.host.name.here:808/. Change 808 to your port number if you used a different one.

mini_httpd supports HTTP authentication. Beware: putting .htpasswd in the web root doesn't protect lower level directories.

If your programs don't need to run as root then you should pick a different user (eg. nobody) and change two things:

1. Change "-u root" to "-u nobody" in /var/service/mini_httpd/run
2. chmod 755 /var/service/mini_httpd/root
