To whom it may concern, 0) Context I have a working wiki farm that mirrors one or more of the WMF wikis from each project (wikipedia, wikibooks, wikisource, wiktionary, ...). I am now trying to enable Extension:CirrusSearch and Extension:Elastica, with a view to retiring Extension:TitleKey and to enabling Extension:Popups. 1) Elasticsearch I setup elasticsearch on a separate PC (darkstar-4). Its status is `green'. I can give commands to it using `curl' from the PC where I have the wiki farm. (shell) curl 'darkstar-4:9200/_cat/health?v' epoch timestamp cluster status node.total node.data shards pri relo init unassign 1411453848 02:30:48 elasticsearch green 1 1 0 0 0 0 0 2) MediaWiki extensions I am following the instructions provided by <https://www.mediawiki.org/wiki/Extension:CirrusSearch>. When I append to `LocalSettings.php' the following lines: require_once "$IP/extensions/CirrusSearch/CirrusSearch.php"; $wgCirrusSearchServers = array( 'darkstar-4' ); and then navigate to <http://simple.wikipedia.site/wiki/Special:Version>, I get the following error. If I comment out the above lines, the page renders properly and shows `Elastica' installed but not `CirrusSearch'. 3) Error message Fatal error: Call to undefined function Elastica\Transport\curl_init() in /usr/share/wp-mirror-mediawiki/extensions/Elastica/Elastica/lib/Elastica/Transport/Http.php on line 183 Call Stack # Time Memory Function Location 1 0.0000 232680 {main}( ) ../index.php:0 2 0.0468 7406888 MediaWiki->run( ) ../index.php:46 3 0.0468 7407952 MediaWiki->main( ) ../Wiki.php:452 4 0.0482 7530816 MediaWiki->performRequest( ) ../Wiki.php:603 5 0.0877 8342448 SpecialPageFactory::executePath( ) ../Wiki.php:288 6 0.0880 8397232 SpecialPage->run( ) ../SpecialPageFactory.php:510 7 0.0955 8959456 SpecialVersion->execute( ) ../SpecialPage.php:361 8 0.1679 10068912 SpecialVersion::softwareInformation( ) ../SpecialVersion.php:128 9 0.1683 10081160 wfRunHooks( ) ../SpecialVersion.php:217 10 0.1683 10081208 Hooks::run( ) ../GlobalFunctions.php:4056 11 0.1684 10081920 call_user_func_array:{/usr/share/wp-mirror-mediawiki/includes/Hooks.php:206} ( ) ../Hooks.php:206 12 0.1684 10082896 CirrusSearch\Hooks::onSoftwareInfo( ) ../Hooks.php:206 13 0.4028 10129040 CirrusSearch\Searcher->getElasticsearchVersion( ) ../Hooks.php:195 14 0.5084 10217552 Elastica\Client->request( ) ../Searcher.php:676 15 0.5142 10230784 Elastica\Request->send( ) ../Client.php:587 16 0.5144 10236736 Elastica\Transport\Http->exec( ) ../Request.php:168 17 0.5144 10236944 Elastica\Transport\Http->_getConnection( ) ../Http.php:51 4) Other notes Git branch: MediaWiki and most extensions wmf/1.24wmf8; wikidata mw1.24-wmf8. OS: GNU/Linux 3.14 amd64. Distribution: Debian jessie (testing). Relevant packages installed: `curl' `php5-curl'. I see that `curl_init()' is also mentioned in `includes/HttpFunctions.php', but am not sure which dependency should be providing `curl_init()'. Sincerely Yours, Kent
5) Fix 5.1) Apparently, I neglected to restart `apache2' after installing `php5-curl'. (rootshell)# /etc/init.d/apache2 restart 5.2) Now `phpinfo()' shows that `curl' is enabled. (shel) php --interactive Interactive mode enabled php > phpinfo(); ... cURL support => enabled ... 5.3) Now <https://simple.wikipedia.site/wiki/Special:Version> shows both `CirrusSearch' and `Elastica' as installed. Sincerely Yours, Kent
Sorry for the trouble!
