一、Sphinx的特性
高速的建立索引(在当代CPU上，峰值性能可达到10 MB/秒);
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);
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);
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;
支持分布式搜索;
可作为MySQL的存储引擎提供搜索服务;
支持布尔、短语、词语相似度等多种检索模式;
文档支持多个全文检索字段(最大不超过32个);
文档支持多个额外的属性信息(例如：分组信息，时间戳等);
停止词查询;
支持单一字节编码和UTF-8编码;
原生的MySQL支持(同时支持MyISAM 和InnoDB );
原生的PostgreSQL 支持.
二、安装中文分词mmseg
下载mmseg
wget http://www.coreseek.com/uploads/sources/mmseg-0.7.3.tar.gz
编译安装
tar zxf mmseg-0.7.3.tar.gz && cd mmseg-0.7.3
./configure --prefix=/usr/local/mmseg
`make && make install
ln -s /usr/local/mmseg/bin/mmseg /usr/bin/
如果出现 make[2]: *** [UnigramCorpusReader.lo] Error 1报错,解决方法如下：
vim src/css/UnigramCorpusReader.cpp
在23行加入#include 重新编译
测试安装成功如下所示
[root@iZ28bak61f3Z bin]#mmseg
Coreseek COS(tm) MM Segment 1.0
Copyright By Coreseek.com All Right Reserved.
Usage: ./mmseg
-u Unigram Dictionary
-r Combine with -u, used a plain text build Unigram Dictionary, default Off
-b Synonyms Dictionary
-h print this help and exit
三、编译安装配置 (MySQL 5.6.24)
下载sphinx
wget http://pkgs.fedoraproject.org/repo/pkgs/sphinx/sphinx-0.9.9.tar.gz/7b9b618cb9b378f949bb1b91ddcc4f54/sphinx-0.9.9.tar.gz
编译安装sphinx
tar zxf sphinx-0.9.9.tar.gz
cd sphinx-0.9.9
yum install python-devel
./configure --prefix=/usr/local/sphinx --with-mysql=/usr/local/mysql/ --with-mysql-includes=/usr/local/mysql/include/ --with-mysql-libs=/usr/local/mysql/lib/ --with-mmseg-includes=/usr/local/mmseg/include/mmseg --with-mmseg-libs=/usr/local/mmseg/lib/ --with-mmseg
make && make install
配置sphinx
cd /usr/local/sphinx/etc/
cp sphinx.conf.dist sphinx.conf
修改以下内容
type = mysql
sql_host = localhost
sql_user = root
sql_pass = ****
sql_db = test
sql_port = 3306
四、建立索引
创建一个test库，导入 example.sql,进行测试
mysql -uroot -p < /usr/local/sphinx/etc/example.sql
索引的建立方法:
/usr/local/sphinx/bin/indexer --config /usr/local/sphinx/etc/sphinx.conf test1
test1为资源名称 不写为默认所有都建立索引,出现如下提示，说明索引建立完成
Sphinx 0.9.9-release (r2117)

using config file '/usr/local/sphinx/etc/sphinx.conf'...
indexing index 'test1'...

五、启动服务器
开启
/usr/local/sphinx/bin/searchd --config /usr/local/sphinx/etc/sphinx.conf
关闭
/usr/local/sphinx/bin/searchd --config /usr/local/sphinx/etc/sphinx.conf --stop
通过search工具查询
/usr/local/sphinx/bin/search --config /usr/local/sphinx/etc/sphinx.conf test

六、sphinx 启动脚本
vim /etc/init.d/sphinx
#!/bin/bash

#
# chkconfig: 345 86 14
