sphinx scws全文檢索的安裝配置步驟

scws是一個由php做的免費的開源的中文分詞系統了，支持 PHP 的擴展方式調用了，下面我們來看看scws全文檢索的安裝配置.

這次搭建的環境：centos 6.5 x86，php 5.3.3，mysql 5.5.8，三次搭建各不相同
一，下載sphinx,scws相關包
sphinx下載地址：http://sphinxsearch.com/downloads/release/
sphinx php擴展下載地址：http://pecl.php.net/package/sphinx
scws下載地址：http://www.xunsearch.com/scws/download.php
scws詞庫下載地址：http://www.xunsearch.com/scws/down/scws-dict-chs-utf8.tar.bz2
二，安裝sphinx,scws,以及php擴展
1,安裝sphinx

 代碼如下 復制代碼 # tar zxvf sphinx-2.2.5-release.tar.gz 
# cd sphinx-2.2.5-release 
# ./configure --prefix=/usr/local/sphinx2 --with-mysql=/usr/local/mysql 
# make && make install 

2,安裝sphinx客戶端
 

 代碼如下 復制代碼 # cd api/libsphinxclient   //sphinx-2.2.5-release目錄下 
# ./configure --prefix=/usr/local/sphinx2/libsphinxclient 
# make && make install 

3,安裝sphinx php擴展

 代碼如下 復制代碼 # tar zxvf sphinx-1.3.1.tgz 
# cd sphinx-1.3.1 
# phpize 
# ./configure --with-sphinx=/usr/local/sphinx2/libsphinxclient --with-php-config=/usr/bin/php-config 
# make && make install 

4,安裝scws
 

 代碼如下 復制代碼 # tar xvjf scws-1.2.2.tar.bz2 
# mkdir /usr/local/scws 
# cd scws-1.2.2 
# ./configure --prefix=/usr/local/scws/ 
# make && make install 

5,安裝scws php擴展

 代碼如下 復制代碼 # cd ./phpext/ 
# phpize 
# ./configure --with-php-config=/usr/bin/php-config 
# make && make install 

三，配置sphinx,scws,php等
1,創建測試表和數據

 代碼如下 復制代碼 mysql> desc users; 
+----------+-------------+------+-----+---------+----------------+ 
| Field | Type | Null | Key | Default | Extra | 
+----------+-------------+------+-----+---------+----------------+ 
| user_id | int(11) | NO | PRI | NULL | auto_increment | 
| username | varchar(20) | NO | | NULL | | 
+----------+-------------+------+-----+---------+----------------+ 
2 rows in set (0.00 sec) 
 
mysql> select * from users; 
+------------+------------+ 
| user_id | username | 
+------------+------------+ 
| 1311895262 | 張三 | 
| 1311895263 | tank張二 | 
| 1311895264 | tank張一 | 
| 1311895265 | tank張 | 
+------------+------------+ 
4 rows in set (0.00 sec) 
mysql> desc orders; 
+--------------+-------------+------+-----+---------+----------------+ 
| Field | Type | Null | Key | Default | Extra | 
+--------------+-------------+------+-----+---------+----------------+

+--------------+-------------+------+-----+---------+----------------+ 
5 rows in set (0.00 sec) 
 
mysql> select * from orders; 
+----+------------+---------------------+----------------+--------------+ 
| id | user_id | create_time | product_name | summary | 
+----+------------+---------------------+----------------+--------------+ 
| 9 | 1311895262 | 2014-08-01 00:24:54 | tank is 坦克 | 技術總監 |

+----+------------+---------------------+----------------+--------------+ 
4 rows in set (0.00 sec) 

上面二張表，都是真實的mysql表
2,配置sphinx.conf，加上以下內容
 

 代碼如下 復制代碼 source myorder 
{ 
 type = mysql 
 sql_host = localhost 
 sql_user = root 
 sql_pass = 
 sql_db = test 
 sql_query_pre = SET NAMES utf8 
 sql_query_pre = SET SESSION query_cache_type=OFF 
 sql_query =  
 SELECT a.id, a.user_id,b.username, UNIX_TIMESTAMP(a.create_time) AS create_time, a.product_name, a.summary  
 FROM orders a left join users b on a.user_id = b.user_id 
 sql_attr_uint = user_id 
 sql_field_string = username 
 sql_field_string = product_name 
 sql_attr_timestamp = create_time 
 
 sql_ranged_throttle = 0 
 #sql_query_info = SELECT * FROM orders WHERE id=$id 
} 
 
index myorder

 ngram_len = 1 
 ngram_chars = U+4E00..U+9FBF, U+3400..U+4DBF, U+20000..U+2A6DF, U+F900..U+FAFF,U+2F800..U+2FA1F, U+2E80..U+2EFF, U+2F00..U+2FDF, U+3100..U+312F, U+31A0..U+31BF,U+3040..U+309F, U+30A0..U+30FF,U+31F0..U+31FF, U+AC00..U+D7AF, U+1100..U+11FF,U+3130..U+318F, U+A000..U+A48F, U+A490..U+A4CF 
} 

注意，新的sphinx，不支持sql_query_info，charset_type設置了，

 代碼如下 復制代碼 WARNING: key 'sql_query_info' was permanently removed from Sphinx configuration. Refer to documentation for details.
WARNING: key 'charset_type' was permanently removed from Sphinx configuration. Refer to documentation for details.

3,安裝scws詞庫
 

 代碼如下 復制代碼 # tar xvjf scws-dict-chs-utf8.tar.bz2 -C /usr/local/scws/etc/ 
 
# chown tank:tank /usr/local/scws/etc/dict.utf8.xdb 

在這裡一定要加權限，也就是說讓php-fpm或者php-cgi的運行用戶，擁有dict.utf8.xdb的所有權限。如果不這麼做的話，php 擴展調用詞庫會報如下錯誤：
Warning: SimpleCWS::add_dict(): Failed to add the dict file
怎麼查看php-fpm,php-cgi的運行用戶呢？
 

 代碼如下 復制代碼 # ps aux |grep php-fpm 
root 23487 0.0 0.1 284928 4652 ? Ss Nov05 0:00 php-fpm: master process (/etc/php-fpm.conf) 
tank 23488 0.0 1.3 336108 52328 ? S Nov05 0:02 php-fpm: pool www  //在這裡就是tank了 
tank 23489 0.0 0.8 310484 34028 ? S Nov05 0:02 php-fpm: pool www 
tank 23490 0.0 0.7 306620 30156 ? S Nov05 0:02 php-fpm: pool www 
tank 23491 0.0 0.8 310096 33748 ? S Nov05 0:02 php-fpm: pool www 
tank 23492 0.0 1.2 331812 47712 ? S Nov05 0:02 php-fpm: pool www 
tank 24669 0.0 1.2 333520 48896 ? S Nov05 0:01 php-fpm: pool www 
tank 29747 0.0 0.7 305000 27340 ? S 03:27 0:00 php-fpm: pool www 
tank 29761 0.0 1.0 320536 39928 ? S 03:27 0:00 php-fpm: pool www 
root 30705 0.0 0.0 103260 872 pts/5 S+ 04:11 0:00 grep php-fpm 

4,配置php.ini
 

 代碼如下 復制代碼 # vim /etc/php.ini 
[sphinx] 
extension = sphinx.so 
 
[scws] 
extension = scws.so 
scws.default.charset = utf-8 
scws.default.fpath = /usr/local/scws/etc 

四，啟動sphinx,php-fpm

 代碼如下 復制代碼 1,啟動sphinx
# /usr/local/sphinx2/bin/indexer --config /usr/local/sphinx2/etc/sphinx.conf --all 
# /usr/local/sphinx2/bin/searchd --config /usr/local/sphinx2/etc/sphinx.conf 
2,重啟php-fpm
# /etc/init.d/php-fpm restart 
前二次，我安裝sphinx，必須在mysql中安裝sphinx存儲插件，而這次沒有，看下圖
mysql 沒有裝 sphinx plugin
mysql 沒有裝 sphinx plugin

五，測試sphinx全文檢索
1,命令行的測試
 

 代碼如下 復制代碼 [root@localhost phpext]# mysql -h 127.0.0.1 -P 9306 
Welcome to the MySQL monitor. Commands end with ; or g.

| 11 | 1311895264 | tank張一 | 1406823894 | tank is 坦克 | 
| 12 | 1311895265 | tank張 | 1406823894 | tank is 坦克 | 
+------+------------+------------+-------------+----------------+ 
4 rows in set (0.00 sec) 

2,利用php 擴展
 

 代碼如下 復制代碼 <?php 
 header("Content-type: text/html; charset=utf-8"); 
 $b_time = microtime(true); 
 echo '<p>'.$b_time.'</p>'; 
 $key = "張三"; 
 $index = "myorder"; 
 //========================================分詞 
 
 $so = scws_new(); 
 $so->set_charset('utf-8'); 
 //默認詞庫 
 $so->add_dict(ini_get('scws.default.fpath') . '/dict.utf8.xdb'); 
 //自定義詞庫 
// $so->add_dict('./dd.txt',SCWS_XDICT_TXT); 
 //默認規則 
 $so->set_rule(ini_get('scws.default.fpath') . '/rules.utf8.ini'); 
 
 //設定分詞返回結果時是否去除一些特殊的標點符號 
 $so->set_ignore(true); 
 
 //設定分詞返回結果時是否復式分割，如“中國人”返回“中國＋人＋中國人”三個詞。 
 // 按位異或的 1 | 2 | 4 | 8 分別表示: 短詞 | 二元 | 主要單字 | 所有單字 
 //1,2,4,8 分別對應常量 SCWS_MULTI_SHORT SCWS_MULTI_DUALITY SCWS_MULTI_ZMAIN SCWS_MULTI_ZALL 
 $so->set_multi(false); 
 
 //設定是否將閒散文字自動以二字分詞法聚合 
 $so->set_duality(false); 
 
 //設定搜索詞 
 $so->send_text($key); 
 $words_array = $so->get_result(); 
 $words = ""; 
 foreach($words_array as $v) 
 { 
 $words = $words.'|('.$v['word'].')'; 
 } 
 
 //加入全詞 
 #$words = '('.$key.')'.$words; 
 $words = trim($words,'|'); 
 $so->close(); 
 echo '<p>輸入：'.$key.'</p>'; 
 echo '<p>分詞：'.$words.'</p>'; 
//========================================搜索 
 $sc = new SphinxClient(); 
 $sc->SetServer('127.0.0.1',9312); 
 #$sc->SetMatchMode(SPH_MATCH_ALL); 
 $sc->SetMatchMode(SPH_MATCH_EXTENDED); 
 $sc->SetArrayResult(TRUE); 
 $res = $sc->Query($words,$index); 
 print_r($res); 
 $e_time = microtime(true); 
 $time = $e_time - $b_time; 
 echo '<p>'.$e_time.'</p>'; 
 
 echo '<p>'.$time.'</p>'; 
 exit; 
?> 
結果如下：
