  scws是一个由php做的免费的开源的中文分词系统了,支持 PHP 的扩展方式调用了,下面我们来看看scws全文检索的安装配置.
 
  这次搭建的环境:centos 6.5 x86,php 5.3.3,mysql 5.5.8,三次搭建各不相同.
 
  一,下载sphinx,scws相关包
 
  sphinx下载地址:http://sphinxsearch.com/downloads/release/
 
  sphinx php扩展下载地址:http://pecl.php.net/package/sphinx
 
  scws下载地址:http://www.xunsearch.com/scws/download.php
 
  scws词库下载地址:http://www.xunsearch.com/scws/down/scws-dict-chs-utf8.tar.bz2
 
  二,安装sphinx,scws,以及php扩展
 
  1,安装sphinx,代码如下:
 
  # 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,安装sphinx客户端,代码如下:
 
  # cd api/libsphinxclient   //sphinx-2.2.5-release目录下   
  # ./configure --prefix=/usr/local/sphinx2/libsphinxclient   
  # make && make install   
  3,安装sphinx php扩展,代码如下:
 
  # 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,安装scws,代码如下:
 
  # 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,安装scws php扩展,代码如下:
 
  # cd ./phpext/   
  # phpize   
  # ./configure --with-php-config=/usr/bin/php-config   
  # make && make install   
  三,配置sphinx,scws,php等.
 
  1,创建测试表和数据,代码如下:
 
  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 | 张三 |   
  | 1311895263 | tank张二 |   
  | 1311895264 | tank张一 |   
  | 1311895265 | tank张 |   
  +------------+------------+   
  4 rows in set (0.00 sec)   
  mysql> desc orders;   
  +--------------+-------------+------+-----+---------+----------------+   
  | Field | Type | Null | Key | Default | Extra |   
  +--------------+-------------+------+-----+---------+----------------+   
  | id | int(11) | NO | PRI | NULL | auto_increment |   
  | user_id | int(11) | NO | | NULL | |   
  | create_time | datetime | NO | | NULL | |   
  | product_name | varchar(20) | NO | | NULL | |   
  | summary | text | NO | | NULL | |   
  +--------------+-------------+------+-----+---------+----------------+   
  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 | 技术总监 |   
  | 10 | 1311895263 | 2014-08-01 00:24:54 | tank is 坦克 | 技术经理 |   
  | 11 | 1311895264 | 2014-08-01 00:24:54 | tank is 坦克 | DNB经理 |   
  | 12 | 1311895265 | 2014-08-01 00:24:54 | tank is 坦克 | 运维总监 |   
  +----+------------+---------------------+----------------+--------------+   
  4 rows in set (0.00 sec)
  上面二张表,都是真实的mysql表.
 
  2,配置sphinx.conf,加上以下内容,代码如下:
 
  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   
  {   
   source = myorder   
   path = /usr/local/sphinx2/var/data/myorder   
   docinfo = extern   
   mlock = 0   
   morphology = none   
   min_word_len = 1   
   #charset_type = zh_cn.utf-8   
   html_strip = 1   
   charset_table = U+FF10..U+FF19->0..9, 0..9, U+FF41..U+FF5A->a..z, U+FF21..U+FF3A->a..z,A..Z->a..z, a..z, U+0149, U+017F, U+0138, U+00DF, U+00FF, U+00C0..U+00D6->U+00E0..U+00F6,U+00E0..U+00F6, U+00D8..U+00DE->U+00F8..U+00FE, U+00F8..U+00FE, U+0100->U+0101, U+0101,U+0102->U+0103, U+0103, U+0104->U+0105, U+0105, U+0106->U+0107, U+0107, U+0108->U+0109,U+0109, U+010A->U+010B, U+010B, U+010C->U+010D, U+010D, U+010E->U+010F, U+010F,U+0110->U+0111, U+0111, U+0112->U+0113, U+0113, U+0114->U+0115, U+0115, U+0116->U+0117,U+0117, U+0118->U+0119, U+0119, U+011A->U+011B, U+011B, U+011C->U+011D, U+011D,U+011E->U+011F, U+011F, U+0130->U+0131, U+0131, U+0132->U+0133, U+0133, U+0134->U+0135,U+0135, U+0136->U+0137, U+0137, U+0139->U+013A, U+013A, U+013B->U+013C, U+013C,U+013D->U+013E, U+013E, U+013F->U+0140, U+0140, U+0141->U+0142, U+0142, U+0143->U+0144,U+0144, U+0145->U+0146, U+0146, U+0147->U+0148, U+0148, U+014A->U+014B, U+014B,U+014C->U+014D, U+014D, U+014E->U+014F, U+014F, U+0150->U+0151, U+0151, U+0152->U+0153,U+0153, U+0154->U+0155, U+0155, U+0156->U+0157, U+0157, U+0158->U+0159, U+0159,U+015A->U+015B, U+015B, U+015C->U+015D, U+015D, U+015E->U+015F, U+015F, U+0160->U+0161,U+0161, U+0162->U+0163, U+0163, U+0164->U+0165, U+0165, U+0166->U+0167, U+0167,U+0168->U+0169, U+0169, U+016A->U+016B, U+016B, U+016C->U+016D, U+016D, U+016E->U+016F,U+016F, U+0170->U+0171, U+0171, U+0172->U+0173, U+0173, U+0174->U+0175, U+0175,U+0176->U+0177, U+0177, U+0178->U+00FF, U+00FF, U+0179->U+017A, U+017A, U+017B->U+017C,U+017C, U+017D->U+017E, U+017E, U+0410..U+042F->U+0430..U+044F, U+0430..U+044F,U+05D0..U+05EA, U+0531..U+0556->U+0561..U+0586, U+0561..U+0587, U+0621..U+063A, U+01B9,U+01BF, U+0640..U+064A, U+0660..U+0669, U+066E, U+066F, U+0671..U+06D3, U+06F0..U+06FF,U+0904..U+0939, U+0958..U+095F, U+0960..U+0963, U+0966..U+096F, U+097B..U+097F,U+0985..U+09B9, U+09CE, U+09DC..U+09E3, U+09E6..U+09EF, U+0A05..U+0A39, U+0A59..U+0A5E,U+0A66..U+0A6F, U+0A85..U+0AB9, U+0AE0..U+0AE3, U+0AE6..U+0AEF, U+0B05..U+0B39,U+0B5C..U+0B61, U+0B66..U+0B6F, U+0B71, U+0B85..U+0BB9, U+0BE6..U+0BF2, U+0C05..U+0C39,U+0C66..U+0C6F, U+0C85..U+0CB9, U+0CDE..U+0CE3, U+0CE6..U+0CEF, U+0D05..U+0D39, U+0D60,U+0D61, U+0D66..U+0D6F, U+0D85..U+0DC6, U+1900..U+1938, U+1946..U+194F, U+A800..U+A805,U+A807..U+A822, U+0386->U+03B1, U+03AC->U+03B1, U+0388->U+03B5, U+03AD->U+03B5,U+0389->U+03B7, U+03AE->U+03B7, U+038A->U+03B9, U+0390->U+03B9, U+03AA->U+03B9,U+03AF->U+03B9, U+03CA->U+03B9, U+038C->U+03BF, U+03CC->U+03BF, U+038E->U+03C5,U+03AB->U+03C5, U+03B0->U+03C5, U+03CB->U+03C5, U+03CD->U+03C5, U+038F->U+03C9,U+03CE->U+03C9, U+03C2->U+03C3, U+0391..U+03A1->U+03B1..U+03C1,U+03A3..U+03A9->U+03C3..U+03C9, U+03B1..U+03C1, U+03C3..U+03C9, U+0E01..U+0E2E,U+0E30..U+0E3A, U+0E40..U+0E45, U+0E47, U+0E50..U+0E59, U+A000..U+A48F, 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   
   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设置了,代码如下:
 
  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,安装scws词库,代码如下:
 
  # tar xvjf scws-dict-chs-utf8.tar.bz2 -C /usr/local/scws/etc/  
 
  # chown tank:tank /usr/local/scws/etc/dict.utf8.xdb  
 
  在这里一定要加权限,也就是说让php-fpm或者php-cgi的运行用户,拥有dict.utf8.xdb的所有权限,如果不这么做的话,php 扩展调用词库会报如下错误:
 
  Warning:SimpleCWS::add_dict(): Failed to add the dict file
 
  怎么查看php-fpm,php-cgi的运行用户呢?代码如下:
 
  # 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  //在这里就是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,代码如下:
 
  # 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,启动sphinx,php-fpm,代码如下:
 
  1,启动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,重启php-fpm
 
  # /etc/init.d/php-fpm restart  
 
  前二次,我安装sphinx,必须在mysql中安装sphinx存储插件,而这次没有.
 
  五,测试sphinx全文检索
 
  1,命令行的测试,代码如下:
 
  [root@localhost phpext]# mysql -h 127.0.0.1 -P 9306   
  Welcome to the MySQL monitor. Commands end with ; or g.   
  Your MySQL connection id is 1   
  Server version: 2.2.5-id64-release (r4825)

  Type 'help;' or 'h' for help. Type 'c' to clear the current input statement.   
     
  mysql> select * from myorder where match('张');   
  +------+------------+------------+-------------+----------------+   
  | id | user_id | username | create_time | product_name |   
  +------+------------+------------+-------------+----------------+   
  | 9 | 1311895262 | 张三 | 1406823894 | tank is 坦克 |   
  | 10 | 1311895263 | tank张二 | 1406823894 | tank is 坦克 |   
  | 11 | 1311895264 | tank张一 | 1406823894 | tank is 坦克 |   
  | 12 | 1311895265 | tank张 | 1406823894 | tank is 坦克 |   
  +------+------------+------------+-------------+----------------+   
  4 rows in set (0.00 sec)   
  2,利用php 扩展,代码如下:
 
  <?php   
   header("Content-type: text/html; charset=utf-8");   
   $b_time = microtime(true);   
   echo '<p>'.$b_time.'</p>';   
   $key = "张三";   
   $index = "myorder";   
   //========================================分词   
     
   $so = scws_new();   
   $so->set_charset('utf-8');   
   //默认词库   
   $so->add_dict(ini_get('scws.default.fpath') . '/dict.utf8.xdb');   
   //自定义词库   
  // $so->add_dict('./dd.txt',SCWS_XDICT_TXT);   
   //默认规则   
   $so->set_rule(ini_get('scws.default.fpath') . '/rules.utf8.ini');   
     
   //设定分词返回结果时是否去除一些特殊的标点符号   
   $so->set_ignore(true);   
     
   //设定分词返回结果时是否复式分割,如“中国人”返回“中国+人+中国人”三个词。   
   // 按位异或的 1 | 2 | 4 | 8 分别表示: 短词 | 二元 | 主要单字 | 所有单字   
   //1,2,4,8 分别对应常量 SCWS_MULTI_SHORT SCWS_MULTI_DUALITY SCWS_MULTI_ZMAIN SCWS_MULTI_ZALL   
   $so->set_multi(false);   
     
   //设定是否将闲散文字自动以二字分词法聚合   
   $so->set_duality(false);   
     
   //设定搜索词   
   $so->send_text($key);   
   $words_array = $so->get_result();   
   $words = "";   
   foreach($words_array as $v)   
   {   
   $words = $words.'|('.$v['word'].')';   
   }   
     
   //加入全词   
   #$words = '('.$key.')'.$words;   
   $words = trim($words,'|');   
   $so->close();   
   echo '<p>输入:'.$key.'</p>';   
   echo '<p>分词:'.$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;   
  ?>   
  结果如下:
  <p>1415214126.9106</p><p>输入:张三</p><p>分词:(张三)</p>Array   
  (   
   [error] =>

   [create_time] => 1406823894   
   [product_name] => tank is 坦克   
   )   
     
   )   
     
   )   
     
   [total] => 1   
   [total_found] => 1   
   [time] => 0   
   [words] => Array
