我用的是ubuntu13.10，在安装完毕sphinxsearch后，在/etc/sphinxsearch/下有个sphinx.conf配置文件(注：不要问我关于windows下如何配置sphinx)

searchd
{
        # [hostname:]port[:protocol], or /unix/socket/path to listen on
        # known protocols are 'sphinx' (SphinxAPI) and 'mysql41' (SphinxQL)
        #
        # multi-value, multiple listen points are allowed
        # optional, defaults are 9312:sphinx and 9306:mysql41, as below
        #
        # listen                        = 127.0.0.1
        # listen                        = 192.168.0.1:9312
        # listen                        = 9312
        # listen                        = /var/run/searchd.sock
        listen                  = 9312
        listen                  = 9306:mysql41
        # log file, searchd run info is logged here
        # optional, default is 'searchd.log'
        log                     = /var/log/sphinxsearch/searchd.log
        # query log file, all search queries are logged here
        # optional, default is empty (do not log queries)
}

在composer.json中的require中添加："yiisoft/yii2-sphinx": "*"
然后在配置文件中添加该插件：

return [
    //....
    'components' => [
        'sphinx' => [
            'class' => 'yii\sphinx\Connection',
            'dsn' => 'mysql:host=127.0.0.1;port=9306;',
            'username' => '',
            'password' => '',
        ],
    ],
];

使用的时候，举个例子如下：

$sql = 'SELECT * FROM idx_item WHERE group_id = :group_id';
$params = [
    'group_id' => 17
];
$rows = Yii::$app->sphinx->createCommand($sql, $params)->queryAll();

searchd
{
    listen = localhost:9306:mysql41
    ...
}

没有解决我遇到的问题。。。
