# Apache / suexec
# Mod Gzip
# Mod Perl
# Mod PHP (built in) w/ pgsql, imap, ftp support
#   xor
# PHP-suexec (standalone) w/ pgsql, imap, ftp support
# Mod SSL
# Mod Throttle

### Step 1: Configuration
SUEXEC=1
MODGZIP=1
MODPERL=0
# You can have mod_php or php-suexec, but NOT BOTH!
MODPHP=0
PHPSUEXEC=1
MODSSL=0
MODTHROTTLE=1

SUEXEC_USER=httpd
SUEXEC_GROUP=nogroup
SUEXEC_UIDMIN=999
SUEXEC_GIDMIN=99

APACHE_VERSION="1.3.27"
PHP_VERSION="4.3.0"
MODSSL_VERSION="2.8.11"
MODPERL_VERSION="1.27"
MODTHROTTLE_VERSION_SHORT="312"
MODTHROTTLE_VERSION_LONG="3.1.2"
### PostgreSQL must be compiled beforehand if you want this to work.
PGSQL_DIR="/usr/local/pgsql"

### Step 2: source code retrieval.

wget http://httpd.apache.org/dist/httpd/apache_$APACHE_VERSION.tar.gz
tar zxf apache_$APACHE_VERSION.tar.gz
wget ftp://ftp.vectorstar.net/pub/apache/http_protocol_vectorstar.patch

  wget http://www.modssl.org/source/mod_ssl-$MODSSL_VERSION-$APACHE_VERSION.tar.gz
  tar zxf mod_ssl-$MODSSL_VERSION-$APACHE_VERSION.tar.gz
fi

### If you are doing either PHP or PHP-suexec, grab this
if [ $MODPHP == 1 || $PHPSUEXEC == 1 ]; then
  wget http://www.php.net/distributions/php-$PHP_VERSION.tar.gz
  tar zxf php-$PHP_VERSION.tar.gz

  wget --passive-ftp ftp://ftp.cac.washington.edu/imap/imap.tar.Z
  tar zxf imap.tar.Z
fi

  cd apache_$APACHE_VERSION

  cd ..
fi

if [ $MODPERL == 1 ]; then
  wget http://perl.apache.org/dist/mod_perl-$MODPERL_VERSION.tar.gz
  tar zxf mod_perl-$MODPERL_VERSION.tar.gz
fi
