LNMP+sphinx实现大数据秒查

Sphinx是由俄罗斯人Andrew Aksyonoff开发的一个全文检索引擎。意图为其他应用提供高速、低空间占用、高结果 相关度的全文搜索功能。Sphinx可以非常容易的与SQL数据库和脚本语言集成。当前系统内置MySQL和PostgreSQL 数据库数据源的支持，也支持从标准输入读取特定格式 的XML数据。

Sphinx的特性如下：

a) 高速的建立索引(在当代CPU上，峰值性能可达到10 MB/秒);

b) 高性能的搜索(在2 - 4GB 的文本数据上，平均每次检索响应时间小于0.1秒);

c) 可处理海量数据(目前已知可以处理超过100 GB的文本数据, 在单一CPU的系统上可处理100 M 文档);

d) 提供了优秀的相关度算法，基于短语相似度和统计（BM25）的复合Ranking方法;

e) 支持分布式搜索;

f) 支持短语搜索

g) 提供文档摘要生成

h) 可作为MySQL的存储引擎提供搜索服务;

i) 支持布尔、短语、词语相似度等多种检索模式;

j) 文档支持多个全文检索字段(最大不超过32个);

k) 文档支持多个额外的属性信息(例如：分组信息，时间戳等);

l) 支持断词;

虽然mysql的MYISAM提供全文索引，但是性能却不敢让人恭维，另外数据库毕竟不是很善于做这样的事情，我们需要把这些活让给更适合的程序去做，减少数据库的压力。因此采用Sphinx来做mysql的全文索引工具是一个很好的选择。这个星期主要来学习这个这个工具的使用，下面将学习过程大致的记录一下，做个备忘，也希望能对学习这个工具的其他朋友有所启发。

1. 安装sphinx

wget http://sphinxsearch.com/files/sphinx-2.2.11-release.tar.gztar -xf sphinx-2.2.11-release.tar.gz  && cd sphinx-2.2.11-release./configure  --prefix=/usr/local/spinx --with-mysqlmake && make installln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib64/libsphinxclient 安装（PHP模块需要）cd api/libsphinxclient./configure -prefix=/usr/local/sphinxmake &&  make install

2.安装php扩展

wget http://pecl.php.net/get/sphinx-1.3.0.tgztar zxf sphinx-1.3.3.tgz && cd sphinx-1.3.3./configure --with-php-config=/usr/local/php/bin/php-config --with-sphinx=/usr/local/sphinx/make &&  make install

3.创建配置文件

cp /usr/local/sphinx/etc/sphinx-min.conf.dist  /usr/local/sphinx/etc/sphinx.conf

## Minimal Sphinx configuration sample (clean, simple, functional)#source src1{        type                    = mysql        sql_host                = localhost        sql_user                = root        sql_pass                = www.123        sql_db                  = test        sql_port                = 3306  # optional, default is 3306        sql_query               = \                SELECT id, group_id, UNIX_TIMESTAMP(date_added) AS date_added, title, content \                FROM documents        sql_attr_uint           = group_id        sql_attr_timestamp      = date_added}index test1{        source                  = src1        path                    = /usr/local/spinx/var/data/test1}indexer{        mem_limit               = 32M}searchd{        listen                  = 9312        listen                  = 9306:mysql41        log                     = /usr/local/spinx/var/log/searchd.log        query_log               = /usr/local/spinx/var/log/query.log        read_timeout            = 5        max_children            = 30        pid_file                = /usr/local/spinx/var/log/searchd.pid        seamless_rotate         = 1        preopen_indexes         = 1        unlink_old              = 1        workers                 = threads # for RT to work        binlog_path             = /usr/local/spinx/var/data}

4.创建索引并启动

/usr/local/spinx/bin/indexer  -c /usr/local/spinx/etc/sphinx.conf --all/usr/local/spinx/bin/searchd  -c /usr/local/spinx/etc/sphinx.conf

5.查询验证

cd /root/sphinx-2.2.11-release/apipython test.py  testDEPRECATED: Do not call this method or, even better, use SphinxQL instead of an APIQuery 'test ' retrieved 3 of 3 matches in 0.000 secQuery stats:        'test' found 5 times in 3 documentsMatches:1. doc_id=1, weight=2, group_id=1, date_added=2016-11-30 01:21:202. doc_id=2, weight=2, group_id=1, date_added=2016-11-30 01:21:203. doc_id=4, weight=1, group_id=2, date_added=2016-11-30 01:21:20
