Question

我使用本教程将原始的sphinx索引转换为实时索引：http://www.ivinco.com/blog/converting-sphinx-original-indexes-to-real-time-indexes/

我改变了我的sphinx.conf：

source movies_dev
{
    type                            = mysql

    sql_host                        = localhost
    sql_user                        = ********
    sql_pass                        = ********
    sql_db                          = ********
    sql_sock                        = /var/run/mysqld/mysqld.sock
    sql_port                        = 3306

    sql_query                       = \
            SELECT \
                    CRC32(movie_id) AS id, movie_id, format_id, active, year, title \
            FROM \
                    movie;
    sql_attr_uint                   = format_id
    sql_attr_uint                   = active
    sql_attr_uint                   = year
    sql_field_string                   = movie_id
    sql_field_string                   = title

    sql_query_info          = SELECT * FROM movie WHERE CRC32(movie_id)=$id
    sql_query_pre = SET NAMES utf8
}

index movies_dev
{
    source                  = movies_dev
    path                    = /var/data/sphinx/movies_dev
    morphology              = stem_en
    enable_star = 1
    min_word_len            = 3
    min_prefix_len          = 0
    min_infix_len           = 3
    charset_type = utf-8
    charset_table   = 0..9, A..Z->a..z, _, a..z, U+410..U+42F->U+430..U+44F, U+430..U+44F, U+DC->U+FC, U+C4->U+E4, U+D6->U+F6, U+DF, U+E4, U+F6, U+FC
}

index rt_movies_dev
{
    type                    = rt
    rt_mem_limit            = 32M

    path                    = /var/data/sphinx/rt_movies_dev
    charset_type            = utf-8

    rt_field                   = movie_id
    rt_field                   = title
    rt_attr_uint                   = format_id
    rt_attr_uint                   = year
    rt_attr_uint                   = active
}

source attach_movies_dev
{
    type                    = mysql

    sql_host                = localhost
    sql_user                = ********
    sql_pass                = ********
    sql_db                  = ********

    sql_query               = SELECT 1 FROM rt_movies_dev
    sql_query_post          = ATTACH INDEX movies_dev TO RTINDEX rt_movies_dev
}

index attach_movies_dev
{
    source                  = attach_movies_dev
    path                    = /var/data/sphinx/attach_movies_dev
    docinfo                 = extern
    charset_type            = utf-8
}

我创建了“rt_movies_dev”表：

SET NAMES utf8;
SET foreign_key_checks = 0;
SET time_zone = '+01:00';
SET sql_mode = 'NO_AUTO_VALUE_ON_ZERO';

DROP TABLE IF EXISTS `rt_movies_dev`;
CREATE TABLE `rt_movies_dev` (
  `movie_id` varchar(20) NOT NULL,
  `format_id` int(10) NOT NULL,
  `title` varchar(255) NOT NULL,
  `year` int(20) DEFAULT NULL,
  `active` tinyint(1) NOT NULL,
PRIMARY KEY (`movie_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

之后，我运行这三个命令：

root@server:~# /usr/local/sphinx/bin/searchd --config /usr/local/sphinx/etc/sphinx.conf;
root@server:~# /usr/local/sphinx/bin/indexer --config /usr/local/sphinx/etc/sphinx.conf movies_dev --rotate;
root@server:~# /usr/local/sphinx/bin/indexer --config /usr/local/sphinx/etc/sphinx.conf attach_movies_dev;

前两个命令后没有错误（除了教程中的警告之外）。但最后一个命令抛出了这个：

ERROR: index 'attach_movies_dev': No fields in schema - will not index.

我不确切地知道错误是什么，我找不到任何有用的东西。你能说出错了吗？我被困在这里。

首先是attach_movies_dev源码，连接到SPHINX，而不是mysql。所以不需要mysql表。

您只是使用索引器来调用SphinxQL命令。

但是从我所看到的尝试索引附加索引，将始终导致错误，因为RT索引本身必须为空（因此可以附加磁盘索引！）

因此，请更改附加索引以连接到searchd。它应该更好。可能是一个空的RT索引，没关系，索引器只会创建一个空索引，但重要的是它仍然会运行_post命令。这是索引存在的全部原因！

还要注意您的磁盘索引和RT索引具有不同的字段，在磁盘索引中，您有两个sql_field_string，它们同时创建属性AND字段。所以你的RT索引应该包含两个匹配的字符串属性（而不仅仅是字段）。
