首先了解一下sphinx全文索引的相关知识
官方网站:http://www.sphinxsearch.com/
官方文档:http://www.sphinxsearch.com/docs/
中文支持:http://www.coreseek.cn/
中文使用手册下载:http://www.coreseek.cn/uploads/pdf/sphinx_doc_zhcn_0.9.pdf
基本上看看上面的官方教程和中文使用手册,你应该会安装和使用Sphix全文索引,当然,还有一些细节,需要不断的google和baidu,那为了节省大家的时间,就出一个完整的Sphinx安装教程和结合PHPWIND程序的使用教程(PHPWIND7.5版本支持)。
接下来开始Sphinx的技术之旅吧!
考虑到Sphinx全文索引使用的实际需要,主要介绍Sphinx全文索引中文方面的支持。
这里需要感谢李沫南同学对Sphinx全文索引中文支持的贡献!
一,Windows下安装Sphinx
1,开始前的准备工作
来源:http://www.coreseek.cn/products/ft_down/
下载csft3.1:http://www.coreseek.cn/uploads/csft/3.1/win32/csft3.1.bin.zip
下载标准词库:http://www.coreseek.cn/uploads/csft/3.1/data.zip
解压:csft3.1.bin.zip 如下目录,解压在C:\csft3.1目录下
解压:data.zip,解压在C:\csft3.1\data目录下 [分词包]
(1)复制 C:\csft3.1\conf\csft.conf.in 文件到 C:\csft3.1\bin\ 目录下,并重命名为csft.conf
注意csft.conf文件里的类似:path = @CONFDIR@/data/test1
把@CONFDIR@替换为C:\csft3.1\ 如上更改为:path = C:\csft3.1\ data\test1
(2)把测试数据 C:\csft3.1\conf\example.sql 导入数据库 [这个基本都会吧!]
(3)建立索引,在DOC界面下运行:indexer.exe --all 如下图,
sql_host = localhost #数据库主机地址
sql_user = test #数据库用户名,拥有数据库所有权限
sql_pass =
sql_db = test #数据库名
sql_port = 3306 #可用端口,一般不需要更改
其它配置使用默认,先体验下sphinx全文索引功能。
(4)测试搜索是否正常,运行:search.exe test 如下图
测试正常将返回
(5)开启搜索进程服务,运行:searchd.exe 如下图
附:PHPWind程序支持Sphinx全文索引的配置。
Windows下安装Sphix使用csft非常简单,如果大家有兴趣可从sphinx[www.sphinxsearch.com]官方下载安装,不过有点复杂,这里就不介绍了,高手们慢慢体验。
二,linux下安装Sphinx全文索引,以CentOS 5.3为例
只能说windows下安装sphinx只是为了体验,因为linux下安装sphinx才是正道。
为了详细体验Centos下安装Sphinx,重新安装Centos系统,完整体验Sphinx安装过程。
Coreseek 全文检索服务器版本已经集成sphinx和中文分词补丁,只需要下载MMSeg和Coreseek Fulltext Server(源代码),就能实现Sphinx服务支持。
下载地址:http://www.coreseek.cn/products/ft_down/
推荐源代码安装
1,开始前的准备工作 [如果已经安装就不需要,如果下面列表没有还有其它的请补上]
1)安装mysql
2)安装php
3)安装apache
4)安装python
5)安装libiconv
6)安装gcc-c++
7)下载Coreseek Fulltext Server(源代码):http://www.coreseek.cn/uploads/csft/3.1/Source/csft-3.1.tar.gz
8)下载Coreseek Mmseg(源代码):http://www.coreseek.cn/uploads/csft/3.1/Source/mmseg-3.1.tar.gz
执行如下命令
yum install python python-dev
2,安装步骤
(1)下载CSFT与MMseg
#wget http://www.coreseek.cn/uploads/csft/3.1/Source/mmseg-3.1.tar.gz
#wget http://www.coreseek.cn/uploads/csft/3.1/Source/csft-3.1.tar.gz
(2)安装MMseg中文分词
# pwd
/usr/local [知道当前的安装目录]
# wget http://www.coreseek.cn/uploads/csft/3.1/Source/mmseg-3.1.tar.gz
# tar xzvf mmseg-3.1.tar.gz
# mkdir /usr/local/mmseg
# cd mmseg-3.1
# ./configure --prefix=/usr/local/mmseg
# make
# make install
运行如下,看看mmseg是否安装成功
# /usr/local/mmseg/bin/mmseg
Coreseek COS(tm) MM Segment 1.0
Copyright By Coreseek.com All Right Reserved.
Usage: /usr/local/mmseg/bin/mmseg
-u
-r Combine with -u, used a plain text build Unigram Dictionary, default Off
-b
-h print this help and exit
(3)安装csft-3.1
# pwd
/usr/local
# wget http://www.coreseek.cn/uploads/csft/3.1/Source/csft-3.1.tar.gz
# tar xzvf csft-3.1.tar.gz
# mkdir /usr/local/csft
# cd csft-3.1
#
./configure --prefix=/usr/local/csft
--with-mmseg=/usr/local/mmseg/bin/mmseg
--with-mmseg-includes=/usr/local/mmseg/include/mmseg/
--with-mmseg-libs=/usr/local/mmseg/lib/
# make
# make install
这里make的时候可能出错,解决如下:
1,检查环境是否安装如下软件
# yum install mysql mysql-devel php-mysql qt4-mysql [mysql环境要首先安装]
# yum install python python-dev
2,是否安装libiconv
下载地址:http://savannah.gnu.org/projects/libiconv/
3,如果还有错误,打开src/Makefile文件,进行修改
# vi src/Makefile 找到182行
LIBS = -lm -lz -lexpat -L/usr/local/lib -lpthread
LIBS = -lm -lz -lexpat -liconv -L/usr/local/lib -lpthread
这样,如果一切顺利,就开始配置你的sphinx全文索引服务器吧[如果安装有什么问题,欢迎在PHPWind官方提问]!
3,按下来就是配置
#cp /usr/local/csft/etc/sphinx-min.conf.dist /usr/local/csft/etc/sphinx.conf
修改sphinx.conf文件中的数据库参数配置,方法同windows下一样
sql_host = localhost
sql_user = root
sql_pass =
sql_db = test
4,把体验数据/usr/local/csft/etc/example.sql 导入到数据库 [这一步应该都会]
5,新建索引
# /usr/local/csft/bin/indexer --all
6,测试搜索
# /usr/local/csft/bin/search test
如果测试有返回,恭喜你的sphinx全文索引服务器配置成功
7,接下来就是支持中文的配置和实现
UTF8编码实例 [如果已经存在utf8的数据库就不需要新建,这里只是举例]
1)创建一个新的数据库,注意编码为utf8_general_ci,如phpwind
2)导入部分现有的GBK数据,如pw_threads
3)配置csft.conf如下
source数据源部分
sql_host = localhost
sql_user = root
sql_pass =
sql_db = phpwind
sql_query_pre = SET NAMES utf8
sql_query_pre = SET SESSION query_cache_type=OFF
sql_query = SELECT tid,fid,authorid,subject FROM pw_threads
sql_attr_uint = fid
sql_attr_uint = authorid
索引部分
charset_type = zh_cn.utf-8
charset_dictpath = /usr/local/csft/
min_prefix_len = 0
min_infix_len = 0
min_word_len = 2
4)创建数据词典
#pwd
/usr/local/mmseg-3.1/data [这是你解压mmseg的目录下的data]
运行如下命令
# mmseg -u unigram.txt
# ll
总计 10152
-rwxr-xr-x 1 root root 715 06-06 18:40 build_unigram.py
-rwxr-xr-x 1 root root 32674 06-06 18:40 char.stat.txt
-rwxr-xr-x 1 root root 1051268 06-06 18:40 Lexicon_full_words.txt
-rwxr-xr-x 1 root root 1826251 06-06 18:40 unigram.txt
-rw-r--r-- 1 root root 3729280 09-16 20:20 unigram.txt.uni
将会生成 unigram.txt.uni 文件
# mv unigram.txt.uni uni.lib
# cp uni.lib /usr/local/csft/ [这就是上面我们在配置索引中用的charset_dictpath]
其它的默认不变,如上方法创建索引
# /usr/local/csft/bin/indexer --all
测试是否成功
# /usr/local/csft/bin/search 测试
以上就是utf8编码的全文索引实现过程
GBK编码实例
与utf8一样,区别在于数据库和数据表使用gbk编码
同时只需要修改如下配置部分[csft.conf]
source数据源部分
sql_query_pre = SET NAMES gbk
索引部分
charset_type = zh_cn.gbk
这里需要注意一下,如果要想测试支持gbk,可以写一个PHP文件,调用sphinx提供的api接口,注意要开启searchd进程
# /usr/local/csft/bin/searchd
编写如下代码 [注意要与sphinxapi.php目录存放在一个目录]
sphinxapi.php目录在# /usr/local/csft-3.1/api/下
也可以直接使用api目录下的test.php直接测试
require_once 'sphinxapi.php';
$sc = new SphinxClient();
$sc->SetServer('127.0.0.1',3312);
$sc->SetConnectTimeout(1);
$sc->SetWeights(array(100,1));
$sc->SetMatchMode(SPH_MATCH_ALL);
$sc->SetArrayResult(TRUE);
$res = $sc->query("简单");
var_dump($res);
?>
也可以直接运行search工具[utf8版],如下
[root@localhost ~]# /usr/local/csft/bin/search 便宜
Coreseek Full Text Server 3.1
Copyright (c) 2006-2008 coreseek.com
using config file '/usr/local/csft/etc/csft.conf'...
index 'test1': query '便宜 ': returned 4 matches of 4 total in 0.015 sec
displaying matches:
1. document=3, weight=1, fid=7, authorid=1
2. document=97, weight=1, fid=35, authorid=1
3. document=108, weight=1, fid=32, authorid=1
4. document=146, weight=1, fid=7, authorid=1
words:
1. '便宜': 4 documents, 4 hits
如果返回false,请检查searchd进程是否开启,如果返回成功,恭喜,你已经成为sphinx的使用者,向下一个高层次进军吧!
三,后记
其实很想制作一个安装视频教程,但由于时间有限,在安装过程中肯定会存在一些细节上的问题,只要大家按照上面的步骤一步一步安装,相信能把sphinx拿下,如果有什么问题
大家可查看http://www.sphinxsearch.com/和http://www.coreseek.cn/网站获取更多帮助,同时也可以查看中文手册。
同时也可以在phpwind官方网站www.phpwind.net提问和分享你的安装过程,把一个细节都亮出来,帮助别人也帮助自己。BY liuhui.php@gmail.com 2009-9-17

附phpwind配置实例[gbk版]
PHPWind搜索sphinx配置实例 [修改部分参数就可直接应用于phpwind程序]
部分解读:
如下全文索引使用的是主索引+增量索引的方式,具体大家结合手册了解相关知识
需要创建一张表 [编码自己定,如下是gbk]
CREATE TABLE IF NOT EXISTS `search_counter` (
`counterid` int(11) NOT NULL DEFAULT '0',
`max_doc_id` int(11) NOT NULL DEFAULT '0',
`min_doc_id` int(10) NOT NULL DEFAULT '0',
PRIMARY KEY (`counterid`)
) ENGINE=MyISAM DEFAULT CHARSET=gbk;
