Managing the sites
table
The sites
table is shipped without data for a new MediaWiki installation.
Importing sites
table from another wiki
There're two ways of populating the sites
table using another wiki as a source.
If you have access to the other wiki's server, you can run the exportSites.php
maintenance script and import the data using the importSites.php
maintenance script of your MediaWiki installation.
If you don't have access to the other wiki's server but the other MediaWiki installation has the SiteMatrix extension installed, you can use a maintenance script from the Wikibase extension (populateSitesTable.php
) to import all sites from the other wiki.
添加新的网站
If you want to add a new site into your MediaWiki's site table, you can use the maintenance script addSite.php
.
Additionally, the above mentioned importSites.php
maintenance script can be used to add an arbitrary group of wikis from custom made XML file in the following format:
<sites version="1.0" xmlns="https://www.mediawiki.org/xml/sitelist-1.0/">
<site type="mediawiki">
<globalid>wikisite1</globalid>
<group>mywikigroup</group>
<path type="file_path">https://www.wikisite1.org/$1</path>
<path type="page_path">https://www.wikisite1.org/index.php/$1</path>
</site>
<site type="mediawiki">
<globalid>wikisite2</globalid>
<group>mywikigroup</group>
<path type="file_path">https://www.wikisite2.org/w/$1</path>
<path type="page_path">https://www.wikisite2.org/wiki/$1</path>
</site>
</sites>
Each <site>
element representing a site.
file_path
and page_path
can be inferred from Special:Version
page of the intended wiki.
Insert wiki family (using Script)
Sometimes, you have to add your wikis in this table. 您可以使用此代码:
$sites = [];
foreach ( [ 'en', 'fr' ] as $langCode ) {
$site = new MediaWikiSite();
$site->setGlobalId( $langCode . 'mywiki' );
$site->setGroup( 'mywiki' );
$site->setLanguageCode( $langCode );
$site->addInterwikiId( $langCode );
$site->addNavigationId( $langCode );
$site->setPath( MediaWikiSite::PATH_PAGE, "http://$langCode.mywiki.org/wiki/$1" );
$site->setPath( MediaWikiSite::PATH_FILE, "http://$langCode.mywiki.org/w/$1" );
$sites[] = $site;
}
$siteStore = MediaWikiServices::getInstance()->getSiteStore();
$siteStore->clear(); // This will remove all previous entries from the table. Remove this call if you want to keep them.
$siteStore->saveSites( $sites );
Reloading the cached sites
table
MediaWiki caches the sites
table in the local-server cache (CACHE_ACCEL
) if it is available (ACPu or WinCache installed).
After making changes to the sites
table using any of the above methods, you should reload or restart any long-running MediaWiki PHP processes: your web server, continuous job runners (if any), etc.
Otherwise, changes to the sites
table will only become effective after the cache expires.
