Change 218625 merged by jenkins-bot:
Point MediaWiki database host to 127.0.0.1

https://gerrit.wikimedia.org/r/218625

So installing with $wgDBServer = localhost causes MediaWiki/PHP to connect over a socket but our HHVM 3.6.x does not support that connection method.

I injected port 3306 to $wgDBServer but that did not make the trick. Thus later switched to 127.0.0.1:3306 which trigger a TCP connection.

I triggered Jenkins jobs mediawiki-phpunit-hhvm pass.

mediawiki-extensions-hhvm fails though:

Flow\Tests\Import\TalkpageImportOperationTest::testImportDoesntCompletelyFail
Flow\Exception\PermissionException: Formatting for wrong user: 127.0.0.1 instead of UTSysop
