======  AWStats config management  ======
AWStats Version which this Document is based on: 6.4

Prefix: AWStats "include" statement does not work as I would an include statement expect to work
so I do not use it. I do not know how it works...

What I have:
  *  /etc/awstats/awstats.conf -> A default config file with default settings
  *  /etc/awstats/awstats.conf.local -> A local config file containing common local settings for every domain

What I want:
  *  One config per domain generated automatically using default- and common settings and and a template
for per domain settings

=====  Template /etc/awstats/template  =====
<code>
#
# domain specific settings
#

SiteDomain="%DOMAIN%"
HostAliases="%ALIASES%"
LogFile="%LOGFILE%"
AllowAccessFromWebToFollowingAuthenticatedUsers="%USERS%"
</code>

=====  Directory /etc/awstats/domain.conf.d/ containing one shell fragment file per domain  =====
Example: links2linux.de
File: /etc/awstats/domain.conf.d/links2linux.de.conf
<code>
# awstats config for links2linux.de
AW_DOMAIN="links2linux.de"
AW_ALIASES="wiki.links2linux.de"
AW_ACCESS_LOG="/var/log/apache/access_links2linux.de.log"
AW_USER="aw-user $AW_SUPERUSER"
</code>

=====  Script to create configs /etc/awstats/create_configs.sh  =====
Whenever you change the template, the common or default settings you only have to run this script again to have fresh configs.
<code>
#!/bin/sh
#
# create awstats configs
#

AW_SUPERUSER="awstats-root"

find domain.conf.d/*.conf | while read CONFIG; do
  . $CONFIG
  echo -n "Creating awstats.$AW_DOMAIN.conf ... "
  echo -n "" > awstats.$AW_DOMAIN.conf
  for f in awstats.conf awstats.conf.local; do
    echo "#" >> awstats.$AW_DOMAIN.conf
    echo "# Include $f" >> awstats.$AW_DOMAIN.conf
    echo "#" >> awstats.$AW_DOMAIN.conf
    sed 's/#.*//;s/^[[awstatsmultidomainsetup|\t]]*//;s/[[awstatsmultidomainsetup|\t]]*$//' $f | sort -u >> awstats.$AW_DOMAIN.conf
  done
  cat template \
    | sed "s|%DOMAIN%|$AW_DOMAIN|" \
    | sed "s|%ALIASES%|$AW_ALIASES|" \
    | sed "s|%LOGFILE%|$AW_ACCESS_LOG|" \
    | sed "s|%USERS%|$AW_USER|" \
    >> awstats.$AW_DOMAIN.conf
    echo "OK"
done

======  Handy tools  ======
=====  recreate_stats.sh - recreate as much stats as possible for one domain  =====
Imagine you changed some common stats parameters like enabling a new plugin and now you want to recreate
as much stats as possible (all stats where logfiles still exist from).
This Script does this automatically:
<code>
#!/bin/sh
#
# recreate awstats for a specific domain
# 
# what does it do?
# 
# what we have:
#   awstats for a sepcific timeframe, maybe much greater than 1 year
#   max last ~52 logfiles ~= 1 year
#
#   what we can do:
#     1) check for which timeframe we have logs now
#     2) remove awstats for that timeframe we detected in 1)
#     3) let awstats create stats from all logfiles

DOMAIN="$1"
LOG="$2"

# try to find LOG automatically if not defined
test "$LOG" || {
  echo "Logfile not specified, trying to find it automatically (in domain.conf.d)"
  if [[awstatsmultidomainsetup|-f domain.conf.d/$DOMAIN.conf ]]; then
    . domain.conf.d/$DOMAIN.conf
    if [[awstatsmultidomainsetup|"$AW_ACCESS_LOG" ]]; then
      echo "Logfile found: $AW_ACCESS_LOG"
      LOG="$AW_ACCESS_LOG"
    else
      echo "Nothing found"
    fi
  fi
}


test "$DOMAIN" || { echo "Syntax: ./me /path/to/access_log example.com "; exit 1; }
test "$LOG"    || { echo "Syntax: ./me /path/to/access_log example.com "; exit 1; }

=====  recreate_all_stats.sh - recreate stats for all domains  =====
Calls the previous script for all domains
<code>
#!/bin/sh
#
# recreate awstats for all known domains
#

find domain.conf.d/*.conf | while read CONFIG; do
  . $CONFIG
  ./recreate_stats.sh $AW_DOMAIN $AW_ACCESS_LOG
done
