• Installer and date: Henrik Thomsen 07:32, 28 February 2009 (UTC)
• Following the instuctions at MW:Extension:SphinxSearch
• Documentation sphinx docs
• Really good article on configuring sphinx
• Downloaded Sphinx from: [1]
• Unpacked and unzipped in /usr/local/sw/sphinx-0.9.9-rc1 om mars.tekkom.dk

Compiling

Sphinx installs default in /usr/local and search for database. No options really nessasary.

1. Executed ./configure which did all the tests succesfully and generated the Makefiles.
2. Executed make to generate the binaries. Showing minor warnings, but ran all tests succesfully
3. Executed make install showing output below

Making install in src
if test -d ../.svn; then svn info .. --xml | perl svnxrev.pl; fi;
make  install-am
test -z "/usr/local/bin" || /usr/local/sw/sphinx-0.9.9-rc1/config/install-sh -d "/usr/local/bin"
  /usr/bin/install -c 'indexer' '/usr/local/bin/indexer'
  /usr/bin/install -c 'searchd' '/usr/local/bin/searchd'
  /usr/bin/install -c 'search' '/usr/local/bin/search'
  /usr/bin/install -c 'spelldump' '/usr/local/bin/spelldump'
Making install in test
test -z "/usr/local/etc" || /usr/local/sw/sphinx-0.9.9-rc1/config/install-sh -d "/usr/local/etc"
 /usr/bin/install -c -m 644 'sphinx.conf.dist' '/usr/local/etc/sphinx.conf.dist'
 /usr/bin/install -c -m 644 'sphinx-min.conf.dist' '/usr/local/etc/sphinx-min.conf.dist'
 /usr/bin/install -c -m 644 'example.sql' '/usr/local/etc/example.sql'
make  install-data-hook
mkdir -p /usr/local/var/data && mkdir -p /usr/local/var/log

• created directory /var/data/tekkom
• created directory /var/data/tekkomstemmed (English morpholgy)

sphnix.conf

• /usr/local/etc/sphinx.conf

Testing the search database

time search "dhcp relay"
search -q "dhcp relay"

Works fine :-), but apparently shows history documents as well. Lets se later when searching the wiki.

Starting the search daemon manually

searchd --config /usr/local/etc/sphinx.conf
