一、Sphinx的特性

高速的建立索引(在當代CPU上，峰值性能可達到10 MB/秒);

高性能的搜索(在2 – 4GB 的文本數據上，平均每次檢索響應時間小于0.1秒);

可處理海量數據(目前已知可以處理超過100 GB的文本數據, 在單一CPU的系統上可

處理100 M 文檔);

提供了優秀的相關度算法，基于短語相似度和統計(BM25)的復合Ranking方法;

支持分布式搜索;

可作為MySQL的存儲引擎提供搜索服務;

支持布爾、短語、詞語相似度等多種檢索模式;

文檔支持多個全文檢索字段(最大不超過32個);

文檔支持多個額外的屬性信息(例如：分組信息，時間戳等);

停止詞查詢;

支持單一字節編碼和UTF-8編碼;

原生的MySQL支持(同時支持MyISAM 和InnoDB );

原生的PostgreSQL 支持.

二、安裝中文分詞mmseg

下載mmseg

wget http://www.coreseek.com/uploads/sources/mmseg-0.7.3.tar.gz

編譯安裝

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/

如果出現 make[2]: *** [UnigramCorpusReader.lo] Error 1報錯,解決方法如下：

vim src/css/UnigramCorpusReader.cpp

在23行加入#include 重新編譯

測試安裝成功如下所示

[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、編譯安裝配置 (MySQL 5.6.24)

下載sphinx

wget http://pkgs.fedoraproject.org/repo/pkgs/sphinx/sphinx-0.9.9.tar.gz/7b9b618cb9b378f949bb1b91ddcc4f54/sphinx-0.9.9.tar.gz

編譯安裝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

修改以下內容

type = mysql

sql_host = localhost

sql_user = root

sql_pass = ****

sql_db = test

sql_port = 3306

四、建立索引

創建一個test庫，導入 example.sql,進行測試

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為資源名稱 不寫為默認所有都建立索引,出現如下提示，說明索引建立完成

Sphinx 0.9.9-release (r2117)

Copyright (c) 2001-2009, Andrew Aksyonoff

using config file '/usr/local/sphinx/etc/sphinx.conf'...

indexing index 'test1'...

collected 4 docs, 0.0 MB

sorted 0.0 Mhits, 100.0% done

total 4 docs, 193 bytes

total 0.030 sec, 6256 bytes/sec, 129.67 docs/sec

total 2 reads, 0.000 sec, 0.1 kb/call avg, 0.0 msec/call avg

total 7 writes, 0.000 sec, 0.1 kb/call avg, 0.0 msec/call avg

五、啟動服務器

開啟

/usr/local/sphinx/bin/searchd --config /usr/local/sphinx/etc/sphinx.conf

關閉

/usr/local/sphinx/bin/searchd --config /usr/local/sphinx/etc/sphinx.conf --stop

通過search工具查詢

/usr/local/sphinx/bin/search --config /usr/local/sphinx/etc/sphinx.conf test

Sphinx 0.9.9-release (r2117)

Copyright (c) 2001-2009, Andrew Aksyonoff

using config file '/usr/local/sphinx/etc/sphinx.conf'...

index 'test1': query 'test ': returned 3 matches of 3 total in 0.000 sec

displaying matches:

1. document=1, weight=2, group_id=1, date_added=Wed Oct 14 15:01:39 2015

words:

1. 'test': 3 documents, 5 hits

六、sphinx 啟動腳本

vim /etc/init.d/sphinx

#!/bin/bash

# sphinx: Startup script for Sphinx search

#

# chkconfig: 345 86 14

# description: This is a daemon for high performance full text /

# search of MySQL and PostgreSQL databases. /

# See http://www.sphinxsearch.com/ for more info.

#

# processname: searchd

# pidfile: $sphinxlocation/var/log/searchd.pid

# Source function library.

. /etc/rc.d/init.d/functions

processname=searchd

servicename=sphinx

username=sphinx

sphinxlocation=/usr/local/sphinx

pidfile=$sphinxlocation/var/log/searchd.pid

searchd=$sphinxlocation/bin/searchd

RETVAL=0

PATH=$PATH:$sphinxlocation/bin

start() {

echo -n $"Starting Sphinx daemon: "

daemon --user=$username --check $servicename $processname

RETVAL=$?

echo

[ $RETVAL -eq 0 ] && touch /var/lock/subsys/$servicename

}

stop() {

echo -n $"Stopping Sphinx daemon: "

$searchd --stop

#killproc -p $pidfile $servicename -TERM

RETVAL=$?

echo

if [ $RETVAL -eq 0 ]; then

rm -f /var/lock/subsys/$servicename

rm -f $pidfile

fi

}

# See how we were called.

case "$1" in

start)

stop

sleep 3

start

condrestart)

if [ -f /var/lock/subsys/$servicename ]; then

stop

sleep 3

start

;;

*)

echo $"Usage: $0 {start|stop|status|restart|condrestart}"

;;

esac

exit $RETVAL

chmod 755 /etc/init.d/sphinx

chkconfig --add sphinx

chkconfig --level 345 sphinx on #開機啟動

service sphinx start #運行

service sphinx stop #停止

service sphinx restart #重啟

service sphinx status #查看是否運行
