(Redirected from Installation of Sphinx search engine)
Contents
Start
- 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.
- Executed ./configure which did all the tests succesfully and generated the Makefiles.
- Executed make to generate the binaries. Showing minor warnings, but ran all tests succesfully
- 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)
Download mediawiki files for sphinx
Download Showfiles Unpack and copy all the files except sphinx.conf /usr/local/www/data/mediawiki/extensions (Create directory if nessasary)
- Option 1:
copy the sphnix.conf file to /usr/local/etc directory and change the file where nessasary. - Option 2:
make your own sphinx.conf file. See below - Option 3: Copy and Edit a preparred sphinx.conf for mediawiki. See next section
sphnix.conf
- /usr/local/etc/sphinx.conf
- First config I made, indexed history of all articles. Only want latest version. See working sphinx.conf below

Indexing the search database

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 start
searchd --config /usr/local/etc/sphinx.conf
Run command script to FreeBSD
Add this file as /usr/local/etc/rc.d/searchd to automatically start search daemon at boot.
#!/bin/sh

. /etc/rc.subr
name="searchd"
rcvar=`set_rcvar`
command="/usr/local/bin/${name}"
load_rc_config $name
run_rc_command "$1"
add the following line to /etc/rc.conf
searchd_enable="YES"
Updating the search database
The search database should be updated at regular intervals to let new articles and changes searchable.
While the database is small I've set the indexer to run once every hour in root's crontab file
3 * * * * /usr/local/bin/indexer --config /usr/local/etc/sphinx.conf --rotate --all >/dev/null 2>&1
- --rotate sends SIGHUP to the searchdaemon to use the new database index
- --all indexes all index'es specified in sphinx.conf
Implementing sphinx in the wiki
extension ExtensionFunctions
Sphinx need teh extension ExtensionFunctions
cd /usr/local/www/data/mediawiki/extensions svn export http://svn.wikimedia.org/svnroot/mediawiki/trunk/extensions/ExtensionFunctions.php
Copying sphinx php extension script
cp /usr/local/sw/sphinx-0.9.9-rc1/api/sphinxapi.php /usr/local/www/data/mediawiki/extensions/SphinxSearch
Installation change
LocalSettings.php
Add the following text to your LocalSettings.php

#$wgSphinxSearch_mode = 'SPH_MATCH_PHRASE';
#$wgSphinxSearch_mode = 'SPH_MATCH_BOOLEAN';
$wgSphinxSearch_mode = 'SPH_MATCH_EXTENDED';
####SPHINX
For different search modes see Sphinx Searching
Sphinx as default search engine
uncomment the following lines in /usr/local/www/mediawiki/extensions/SphinxSearch/SphinxSearch.php
$wgDisableInternalSearch = true;
$wgDisableSearchUpdate = true;
$wgSearchType = 'SphinxSearch';
Did you mean suggestions
Uses aspell or pspell. Aspell configured uncomment and change lines in usr/local/www/mediawiki/extensions/SphinxSearch/SphinxSearch.php
# Path to where aspell has location and language data files. Leave commented out if unsure
#$wgSphinxSearchPspellDictionaryDir = "/usr/local/lib/aspell-0.60/";
# Path to personal dictionary (for example personal.en.pws.) Needed only if using a personal dictionary
$wgSphinxSearchPersonalDictionary = "/usr/local/www/data/mediawiki/aspell.en_US.per";
# Path to Aspell. Needed only if using command line interface instead of the PHP built in PSpell interface.
$wgSphinxSearchAspellPath = "/usr/local/bin/aspell";
Configuring aspell
Aspell default don't accept special characters in dictionary files such as '-' or '0123456789'
