Sphinx+MySQL5.1x+SphinxSE+mmseg

一.不停止mysql的情况下安装SphinxSE

1.确定mysql版本,下载对应源码包

此处下载5.1.69的mysql源码包

#wget ftp://ftp.ntu.edu.tw/pub/MySQL/Downloads/MySQL-5.1/mysql-5.1.69.tar.gz

解压

2.下载sphinx:

#wget http://sphinxsearch.com/downloads/sphinx-0.9.9.tar.gz

解压

3.拷贝mysqlse到mysql5.1.69下的storage/sphinx

#cp -r sphinx-0.9.9/mysqlse/ mysql-5.1.69/storage/sphinx

4.编译

#cd mysql-5.1.69

#sh BUILD/autorun.sh

#./configure

#make

5.mysql插入sphinx引擎

#cd ./mysql-5.1.69

#cd ./storage/sphinx/.libs

#cp ha_sphinx.* /usr/lib64/mysql/plugin

更改所有者

#chown mysql.mysql /usr/lib64/mysql/plugin/*

登录mysql,插入引擎

#mysql -u root -p -h localhost

#mysql> INSTALL PLUGIN sphinx SONAME 'ha_sphinx.so';

检查引擎是否安装

#mysql> show engines;

如果出现sphinx引擎,则表明已正常安装

二.安装Coreseek,使其支持中文索引及检索

1.安装autoconf

2.下载coreseek3.2.14.tar.gz,并解压缩

3.安装mmseg分词

#cd coreseek-3.2.14

#./bootstrap

#./configure --prefix=/usr/local/mmseg3

#make

#make install

4.安装csft

#cd ../csft-3.2.14/

#sh buildconf.sh

#./configure --prefix=/usr/local/coreseek --without-unixodbc --with-mmseg --with-mmseg-includes=/usr/local/mmseg3/include/mmseg/ --with-mmseg-libs=/usr/local/mmseg3/lib/ --with-mysql

===========================================================

##如果出现错误提示：“ERROR: cannot find MySQL include files.......To disable MySQL support, use --without-mysql option.“，可按照如下方法处理：

##请找到头文件mysql.h所在的目录，一般是/usr/local/mysql/include，请替换为实际的

##请找到库文件libmysqlclient.a所在的目录，一般是/usr/local/mysql/lib，请替换为实际的

##configure参数加上：--with-mysql-includes=/usr/local/mysql/include --with-mysql-libs=/usr/local/mysql/lib，执行后，重新编译安装

============================================================

#make

#make install

三.配置并测试

1.进入coreseek目录

#cd /usr/local/coreseek/etc

#ls

可以看到三个文件

example.sql sphinx.conf.dist sphinx-min.conf.dist

#cp sphinx.conf.dist sphinx.conf

2.配置sphinx.conf

source src1

{

type = mysql

sql_host = localhost

sql_user = root

sql_pass = 123456

sql_db = test

sql_port = 3306 # optional, default is 3306

sql_sock = /var/lib/mysql/mysql.sock

sql_query_pre = SET NAMES utf8

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

sql_query_info = SELECT * FROM documents WHERE id=$id

}

index test1

{

source = src1

path = /usr/local/coreseek/var/data/test1

docinfo = extern

charset_type = zh_cn.utf-8

mlock = 0

morphology = none

min_word_len = 1

html_strip = 0

charset_dictpath = /usr/local/mmseg3/etc/

ngram_len = 0

}

indexer

{

mem_limit = 32M

}

searchd

{

port = 9312

log = /usr/local/coreseek/var/log/searchd.log

query_log = /usr/local/coreseek/var/log/query.log

read_timeout = 5

max_children = 30

pid_file = /usr/local/coreseek/var/log/searchd.pid

max_matches = 1000

seamless_rotate = 1

preopen_indexes = 0

unlink_old = 1

}

3.创建test数据库,并建立表documents,sql语句如下

DROP TABLE IF EXISTS test.documents;

CREATE TABLE test.documents

(

id INTEGER PRIMARY KEY NOT NULL AUTO_INCREMENT,

group_id INTEGER NOT NULL,

group_id2 INTEGER NOT NULL,

date_added DATETIME NOT NULL,

title VARCHAR(255) NOT NULL,

content TEXT NOT NULL

);

REPLACE INTO test.documents ( id, group_id, group_id2, date_added, title, content ) VALUES

( 1, 1, 5, NOW(), 'test one', 'this is my test document number one. also checking search within phrases.' ),

( 2, 1, 6, NOW(), 'test two', 'this is my test document number two' ),

( 3, 2, 7, NOW(), 'another doc', 'this is another group' ),

( 4, 2, 8, NOW(), 'doc number four', 'this is to test groups' );

DROP TABLE IF EXISTS test.tags;

CREATE TABLE test.tags

(

docid INTEGER NOT NULL,

tagid INTEGER NOT NULL,

UNIQUE(docid,tagid)

);

INSERT INTO test.tags VALUES

(1,1), (1,3), (1,5), (1,7),

(2,6), (2,4), (2,2),

(3,15),

(4,7), (4,40);

4.生成索引

#/usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/sphinx.conf --all

其中参数--all表示生成所有索引

当然也可以是索引的名字例如：#/usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/sphinx.conf test1

执行后可以在/usr/local/coreseek/var/data目录中看到多出一些文件,是以索引名为文件名的不同的扩展名的文件

在不启动sphinx的情况下即可测试命令:

#/usr/local/coreseek/bin/search -c /usr/local/coreseek/etc/sphinx.conf number

#/usr/local/coreseek/bin/search -c /usr/local/coreseek/etc/sphinx.conf number --filter group_id 2

限定group_id 为2 返回一条记录

我们插入几条数据来测试中文

set names utf8 之前一定要设置字符集

INSERT INTO `test`.`documents` (

`id` ,

`group_id` ,

`group_id2` ,

`date_added` ,

`title` ,

`content`

)

VALUES (

NULL , '2', '3', '2011-02-01 00:37:12', '研究生的故事', '研究生自主创业'

), (

NULL , '1', '1', '2011-01-28 00:38:22', '研究', '为了创业而研究生命科学'

);

插入数据后需要重新索引

#/usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/sphinx.conf test1

进行测试

#/usr/local/coreseek/bin/search -c /usr/local/coreseek/etc/sphinx.conf 研究生创业

四.实际使用

1.作为守护进程启动

#/usr/local/coreseek/bin/searchd -c /usr/local/coreseek/etc/sphinx.conf

2.建立一个sphinx引擎的表

CREATE TABLE t1

(

id INTEGER UNSIGNED NOT NULL,

weight INTEGER NOT NULL,

query VARCHAR(3072) NOT NULL,

group_id INTEGER,

INDEX(query)

) ENGINE=SPHINX CONNECTION="sphinx://localhost:9312/test1";

搜索表前三列的类型必须是INTEGER，INTEGER和VARCHAR，这三列分别对应文档ID，匹配权值和搜索查询。查询列必须被索引，其他列必须无索引。列的名字会被忽略，所以可以任意命名，参数CONNECTION来指定用这个表搜索时的默认搜索主机、端口号和索引，语法格式：CONNECTION="sphinx://HOST:PORT/INDEXNAME"。

执行SQL语句 select d.id,d.title,d.content from t1 join documents as d on t1.id = d.id and t1.query = '研究生创业';

即可查询结果

3.在不停止searchd的情况下主索引

插入数据后创建主索引

#/usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/sphinx.conf test1 --rotate

对于实际应用,应该是主索引+增量索引
