Build nginx on an Accelerator with support for flash video. Assumes you have PCRE and OpenSSL built as per the wiki/forum. Keep everything tidy in /opt/local/nginx.

./configure --prefix=/opt/local/nginx --with-http_ssl_module --with-openssl=../openssl-0.9.8e --with-cc-opt="-m64 -I/usr/local/include -I/usr/local/ssl/include" --with-ld-opt="-L/lib/64 -L/usr/sfw/lib/64 -R/usr/sfw/lib/64 -R/lib/64 -L/usr/local/ssl/lib -m64 -L/usr/local/lib -R/usr/local/lib" --with-http_flv_module

# Some configuration options:
PREFIX: Let -prefix= default to /usr/local/nginx
--with-cc-opt="-I /usr/local/include"

# from http://wiki.codemongers.com/NginxInstall:
# --with-cc-opt=OPTIONS - Additional parameters which will be added to the variable CFLAGS.
# With the use of the system library PCRE in FreeBSD, it is necessary to indicate 
# --with-cc-opt="-I /usr/local/include". If we are using select() and it is necessary
# to increase the number of file descriptors, then this also can be assigned here:
# --with-cc-opt="-D FD_SETSIZE=2048".

# Look for configuration options:
./configure --help

# Make directory for log files (my preferences!)
mkdir /var/log/nginx
mkdir /var/log/nginx/drupal
chmod -R 777 /var/log/nginx

mkdir /usr/local/etc/nginx
chown www /usr/local/etc/nginx
chmod 775 /usr/local/etc/nginx

# I tell it where to put the nginx binary. Specifically not in the path. Scripts will start it.
# I like to put conf files in /usr/local/etc/
# I like to put pid files in /var/run
# I have PCRE in /usr/local/include (look for pcre.h)

# Test nginx configuration
/usr/local/nginx/nginx -t -c /usr/local/etc/nginx/nginx.conf

# Run it on port 81. Note that conf file was modified. Change it back for production use.
# First spawn an FCGI process to pass PHP scripts to.
# php was compiled like this:
# ./configure --enable-cgi --enable-fastcgi --enable-force-redirect (plus more flags)
# so PHP resides in /usr/local/bin/
# Note I specified port 9000 in the nginx.conf file. Must match here:
/usr/local/bin/spawn-fcgi -f /usr/local/bin/php -a 127.0.0.1 -p 9000 -u www

// output: spawn-fcgi.c.190: child spawned successfully: PID: 6414

# Then start the nginx.
