Sphinx+Scws 搭建千万级准实时搜索&应用场景详解

2014-03-23 00:00 573 查看
目标： 一、搭建准确的千万级数据库的准实时搜索（见详情） 二、实现词语高亮（客户端JS渲染，服务器端渲染，详见7.3） 三、实现搜索联想（输入框onchange,ajax请求搜索，取10条在层上展示方可） 四、实现词库管理（仅需管理scws下的自定义词库dd.txt即可） 五、实现全文搜索（提供了两种方案，详见8） 案例： 本文第五部分，针对实际应用场景，典型案例分析。 软件： sphinx: sphinx-2.0.2-beta scws: scws-1.2.0 =========================================================================== 一、Sphinx安装 1、安装
# ./configure --prefix=/opt/server/sphinx --with-mysql=/opt/server/mysql
# make
# make install
2、配置 见sphinx.conf 详见下文，多索引增量索引方案 3、php 扩展 性能方面，扩展和直接使用API文件，差别不大；可以做选择；都在源码API中； 个人建议使用API文件，系统更稳定 3.1 sphinx客户端libsphinxclient
# ./configure --prefix=/opt/server/libsphinxclient
# make
# make install
3.2 扩展 下载 http://pecl.php.net/package/sphinx 
# /opt/server/php/bin/phpize./configure --with-sphinx=/opt/server/libsphinxclient --with-php-config=/opt/server/php/bin/php-config
# make
# make install
查看
# /opt/server/php/bin/php -m |grep sphinx
使用手册 http://docs.php.net/manual/zh/book.sphinx.php 4、索引 启动服务
# /opt/server/sphinx/bin/indexer --all
# /opt/server/sphinx/bin/searchd
二、php 分词 scws 官网 http://www.ftphp.com/scws/ 1、 安装
# ./configure --prefix=/opt/server/scws
# make
# make install
2、 词库 scws-dict-chs-utf8.tar.bz2 解压放入 /opt/server/scws/etc 词库 dict.utf-8.xdb 规则 rules.utf-8.ini 3、 php 扩展 源码在phpext下
# /opt/server/php/bin/phpize./configure --with-scws=/opt/server/scws --with-php-config=/opt/server/php/bin/php-config
# make
# make install

# vi php.ini
[scws]
extension = scws.so
scws.default.charset = utf-8
scws.default.fpath = /opt/server/scws/etc
查看
# /opt/server/php/bin/php -m |grep scws
4、 分词测试 http://www.ftphp.com/scws/docs.php 详见测试文件 test_all.php 三、 索引
//索引某个索引
# /opt/server/sphinx/bin/indexer test1
//searchd 索引某个索引
# /opt/server/sphinx/bin/indexer test1 --rotate
//指定索引搜索
# /opt/server/sphinx/bin/indexer -i test1 '逗她男'
1、 增量索引方案
//创建表记录偏移
CREATE TABLE IF NOT EXISTS `search_counter` (
`counterid` int(11) unsigned NOT NULL AUTO_INCREMENT COMMENT '统计标示',
`max_doc_id` int(11) unsigned NOT NULL COMMENT '已统计数',
PRIMARY KEY (`counterid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;
//增量索引
# /opt/server/sphinx/bin/indexer test1stemmed --rotate
//合并索引
# /opt/server/sphinx/bin/indexer --merge test1 test1stemmed --rotate
索引策略 1、搜索时，同时从主索引和增量索引取数据 2、每5分钟，运行一次增量索引；满足新数据搜索需求 3、每晚，运行一次主索引，同时会更新索引标示；再运行增量索引，实质为清空增量索引，避免与主索引重复索引 4、好处：避免开合并索引，合并索引效率较差 5、如数据量特别大，可考虑合并索引的方案 索引策略shell
//add.sh
#!/bin/sh
/opt/server/sphinx/bin/indexer test1stemmed --rotate >> /opt/server/sphinx/var/log/add.sh.log
//all.sh
#!/bin/sh
/opt/server/sphinx/bin/indexer test1 --rotate >> /opt/server/sphinx/var/log/all.sh.log
/opt/server/sphinx/bin/indexer test1stemmed --rotate >> /opt/server/sphinx/var/log/add.sh.log
四、 多个表独立索引方案 场景：如有用户搜索、商品搜索等多个索引需求 策略：配置一个多索引方案，每个表单独建立索引 前端根据不同类型选择不同的查询索引；全部，即选择所有索引 =========================================================================== 五、性能及应用场景总结 1、基础数据、假如我们是一家商城；有用户user，商品goods，以及增量索引计数表search_counter。
--
-- 数据库: `sphinx`
--
-- --------------------------------------------------------
--
-- 表的结构 `goods`
--
CREATE TABLE IF NOT EXISTS `goods` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT COMMENT '商品ID',
`name` varchar(50) NOT NULL COMMENT '商品名称',
`price` int(11) NOT NULL COMMENT '商品价格',
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;
-- --------------------------------------------------------
--
-- 表的结构 `user`
--
CREATE TABLE IF NOT EXISTS `user` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT COMMENT '用户ID',
`name` varchar(50) NOT NULL COMMENT '用户昵称',
`info` text NOT NULL COMMENT '用户简介',
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;
-- --------------------------------------------------------
--
-- 表的结构 `search_counter`
--
CREATE TABLE IF NOT EXISTS `search_counter` (
`counterid` int(11) unsigned NOT NULL AUTO_INCREMENT COMMENT '统计标示',
`max_doc_id` int(11) unsigned NOT NULL COMMENT '已统计数',
PRIMARY KEY (`counterid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;
-- --------------------------------------------------------
--
-- 统计初始值 `search_counter`
--
INSERT INTO `search_counter` (`counterid`, `max_doc_id`) VALUES
(1, 0),
(2, 0);
2、编写配置文件 sphinx.conf

3、索引，启动服务
# /opt/server/sphinx/bin/indexer --all
# /opt/server/sphinx/bin/searchd
4、索引方案 索引策略 1、搜索时，同时从主索引和增量索引取数据 2、每5分钟，运行一次增量索引；满足新数据搜索需求 3、不同表的索引，分别执行方可 4、每晚，运行一次主索引，同时会更新索引标示；再运行增量索引，实质为清空增量索引，避免与主索引重复索引 5、好处：避免开合并索引，合并索引效率较差 6、如数据量特别大，可考虑合并索引的方案 索引策略shell
//add.sh
#!/bin/sh
/opt/server/sphinx/bin/indexer useradd goodsadd --rotate >> /opt/server/sphinx/var/log/add.sh.log
//all.sh

6、小结 通过分词 和 采用 SPH_MATCH_EXTENDED (Sphinx内部查询语言的表达式) 模式； 能获取较好的搜索结果，排序和权值都是比较理想的。 7、优化扩展 7.1 如访问量较大，可将分词结果添加一层memecache，避免每次调用分词接口。 7.2 本文的的准实时索引，只对新增数据有效，如修改了老数据的内容则不能及时索引。 补充方案:(基于性能，不推荐) 7.2.1 全文重新索引 7.2.1在启一个索引为 updategoods，当数据发生改变时候，将来变化数据ID存如数据库，动态读取更新； 定时将更新的数据merge到主索引 7.3 词语高亮 利用API，SphinxClient::buildExcerpts可实现对关键词加入标签高亮
public array SphinxClient::buildExcerpts ( array $docs , string $index , string $words [, array $opts ] )
$opts 可实现对索引ID，搜索出的详情数组；进行匹配处理，得出理想的搜索结果。具体参数，见PHP手册。 8、全文搜索 由于sphinx索引ID唯一的问题，跨表的全文搜索不能直接实现；即，不能简单通过查询多个索引而获得结果； 不过通过如下方式，亦可实现全文搜索。 方案A 可在索引时对每个表的ID进行处理； 如：SELECT (id+1000000) AS id,name,price FROM goods; 在提供外部使用时，根据规则（如：ID > 1000000 为商品类）还原相应ID即可。 方案B 将数据来源存储为一个属性,将类比在属性中返回；获得的结果集中，可通过source_id进行类别区分了；如下：
source src1
{
sql_query = SELECT id, 1 AS source_id FROM table1
sql_attr_uint = source_id
…
}
source src2
{
sql_query = SELECT id, 2 AS source_id FROM table2
sql_attr_uint = source_id
…
}
