#####
# 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=1
PHPSUEXEC=0
MODSSL=0
MODTHROTTLE=1

SUEXEC_USER=httpd
SUEXEC_GROUP=nofiles
SUEXEC_UIDMIN=999
SUEXEC_GIDMIN=100

APACHE_VERSION="1.3.27"
PHP_VERSION="4.2.3"
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

if [ $MODSSL == 1 ]; then
  #wget http://www.modssl.org/source/mod_ssl-$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 ftp://ftp.cac.washington.edu/imap/imap.tar.Z
  tar zxf imap.tar.Z
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

if [ $MODTHROTTLE == 1 ]; then
  #wget http://www.snert.com/Software/mod_throttle/mod_throttle$MODTHROTTLE_VERSION_SHORT.tgz
  tar zxf mod_throttle$MODTHROTTLE_VERSION_SHORT.tgz
fi

if [ $MODGZIP == 1 ]; then
  #wget http://www.remotecommunications.com/apache/mod_gzip/src/1.3.19.1a/mod_gzip.c.gz
  gunzip mod_gzip.c.gz
fi

### Step 3: Compilation.
