# Apache 2.x
#   suexec
#   SSL
#   Compression (now mod_deflate and mod_headers)
#   see http://wiki.vhcs.net/en/index.php/HowTo:_Apache2_Gzip_Content-Encoding
#     http://httpd.apache.org/docs-2.0/mod/mod_deflate.html
#
# PHP (suexec) w/ pgsql, mysql, imap, ftp support
#
# mod_cband for throttling

### Step 1: Configuration
SUEXEC=1
COMPRESS=1
CBAND=1
PHP=1
SSL=1
IMAP=0

SUEXEC_USER=httpd
SUEXEC_GROUP=nobody
SUEXEC_UIDMIN=999
SUEXEC_GIDMIN=100

APACHE_VERSION="2.0.59"
PHP_VERSION="5.2.1"
CBAND_VERSION="0.9.7.5"
PGSQL_DIR="/usr/local/pgsql"
MYSQL_DIR="/usr/local/mysql"

###
### Step 2: source code retrieval.
###

wget http://mirror.candidhosting.com/pub/apache/httpd/httpd-$APACHE_VERSION.tar.bz2
tar xjf httpd-$APACHE_VERSION.tar.bz2

wget --passive-ftp ftp://ftp.vectorstar.net/pub/apache-2.x/http-service-unavailable.patch
cd httpd-$APACHE_VERSION
patch -p0 < ../http-service-unavailable.patch
cd ..
if [ $CBAND == 1 ]; then
  wget http://cband.linux.pl/download/mod-cband-$CBAND_VERSION.tgz
  tar xzf mod-cband-$CBAND_VERSION.tgz
fi

if [ $PHP == 1 ]; then
  if [ $SUEXEC == 1 ]; then
    wget --passive-ftp ftp://ftp.vectorstar.net/pub/apache-2.x/httpd-2.x-suexec.patch
    cd httpd-$APACHE_VERSION
    patch -p0 < ../httpd-2.x-suexec.patch
    cd ..
  fi
  if [ $IMAP == 1 ]; then
    wget --passive-ftp ftp://ftp.cac.washington.edu/imap/imap.tar.Z
    tar zxf imap.tar.Z
  fi
  wget http://us2.php.net/distributions/php-$PHP_VERSION.tar.bz2

### Step 3: Compilation.
