php启用sphinx全文搜索的实现方法

本文实例讲述了php启用sphinx全文搜索的实现方法。分享给大家供大家参考。具体分析如下：

在编译安装 sphinx 的时候出现很多中文乱码,最后抛出错误卡住了,我去到官方直接下载一个 rpm 包,安装就很爽,具体错误不想研究了,忙开发呢.

安装两个包,一个是 mmseg 这个是生成中文字典的程序,一个是  csft 也就是中国版的sphinx .

rpm -ivh 安装完以后,很顺利~~不到半分钟就装完了.

中文字典库,我直接去 csft 官方下载了,挺好的想得很周到.

unigram.txt  uni.lib

unigram.txt  字典文本,可以在里面添加你自己的关键字.

然后使用:mmseg -u unigram.txt 生成字典文件:unigram.txt.uni 然后重命名一下  uni.lib 这个就是sphinx 认识的字典了.

放哪里？放你在 sphinx.conf 里面配置的字典路径里面,等会说到,然后基本就差不多了,在看下sphinx 几个实用的程序:复制代码 代码如下:[root@beihai365 /]# csft-

csft-indexer  csft-search   csft-searchd

csft-indexer  是生成全文搜索索引的 程序

csft-search  是测试搜索是否生效用的，也很好用，不如我还没用客户端脚本开发，就可以用这个来查看全文搜索是否成功

csft-searchd  这个就是 sphinx 搜索的守护程序了。 启动以后，就可以用脚本 php python 等，开查询了。

就那么简单,在看下关键的两部分东西.

sphinx.conf 配置文件:复制代码 代码如下:source tmsgs    {            type                                    = mysql            sql_host                                = localhost            sql_user                                = root            sql_pass                                = 1            sql_db                                  = phpwind75sp3            sql_port                                = 3306  # optional, default is 3306            #sql_sock                                = /tmp/mysql3307.sock            sql_query_pre                           = SET NAMES gbk            sql_query                               = SELECT id,name,type,stock FROM pw_tools            #sql_attr_uint                          = id            sql_attr_uint                           = stock    }       index tmsgsindex    {            source                                  = tmsgs            path                                    = /var/mmseg/searchdata/beihai365            docinfo                                 = extern            charset_type                            = zh_cn.gbk            #min_prefix_len  = 0            #min_infix_len  = 2            #ngram_len = 2            charset_dictpath                        = /var/mmseg/data            #min_prefix_len                          = 0            #min_infix_len                           = 0            #min_word_len                            = 2    }       indexer    {            mem_limit                               = 128M    }       searchd    {            #listen                                = 3312            log                                 = /var/log/searchd.log            query_log                           = /var/log/query.log            read_timeout                        = 5            max_children                        = 30            pid_file                            = /var/log/searchd.pid            max_matches                         = 1000            #seamless_rotate                     = 1            #preopen_indexes                     = 0            #unlink_old                          = 1    }   source tmsgs {         type                                    = mysql         sql_host                                = localhost         sql_user                                = root         sql_pass                                = 1         sql_db                                  = phpwind75sp3         sql_port                                = 3306  # optional, default is 3306         #sql_sock                                = /tmp/mysql3307.sock         sql_query_pre                           = SET NAMES gbk         sql_query                               = SELECT id,name,type,stock FROM pw_tools         #sql_attr_uint                          = id         sql_attr_uint                           = stock } index tmsgsindex {         source                                  = tmsgs         path                                    = /var/mmseg/searchdata/beihai365         docinfo                                 = extern         charset_type                            = zh_cn.gbk         #min_prefix_len  = 0         #min_infix_len  = 2         #ngram_len = 2         charset_dictpath                        = /var/mmseg/data         #min_prefix_len                          = 0         #min_infix_len                           = 0         #min_word_len                            = 2 } indexer {         mem_limit                               = 128M } searchd {         #listen                                = 3312         log                                 = /var/log/searchd.log         query_log                           = /var/log/query.log         read_timeout                        = 5         max_children                        = 30         pid_file                            = /var/log/searchd.pid         max_matches                         = 1000         #seamless_rotate                     = 1         #preopen_indexes                     = 0         #unlink_old                          = 1 }再看一下,测试客户端代码:复制代码 代码如下:<?php        header("Content-type:text/html;charset=utf-8");        include "sphinxapi.php";        $cl = new SphinxClient();        $cl->SetServer("localhost",3312);        $cl->SetMatchMode(SPH_MATCH_ALL);        $cl->SetArrayResult(true);        $res = $cl->Query("名卡","*");        print_r($res);    ?>   <?php header("Content-type:text/html;charset=utf-8"); include "sphinxapi.php"; $cl = new SphinxClient(); $cl->SetServer("localhost",3312); $cl->SetMatchMode(SPH_MATCH_ALL); $cl->SetArrayResult(true); $res = $cl->Query("名卡","*"); print_r($res); ?>“名卡”这个关键字是我自己手动在字典里面添加的,看是否能真的搜到,实例代码如下:复制代码 代码如下:Array    (        [error] =>         [warning] =>         [status] => 0        [fields] => Array            (                [0] => name                [1] => type            )           [attrs] => Array            (                [stock] => 1            )           [matches] => Array            (                [0] => Array                    (                        [id] => 8                        [weight] => 1                        [attrs] => Array                            (                                [stock] => 100                            )                    )            )        [total] => 1        [total_found] => 1        [time] => 0.018        [words] => Array            (                [名卡] => Array                    (                        [docs] => 1                        [hits] => 1                    )            )    )   Array (     [error] =>      [warning] =>      [status] => 0     [fields] => Array         (             [0] => name             [1] => type         )     [attrs] => Array         (             [stock] => 1         )     [matches] => Array         (             [0] => Array                 (                     [id] => 8                     [weight] => 1                     [attrs] => Array                         (                             [stock] => 100                         )                 )         )     [total] => 1     [total_found] => 1     [time] => 0.018     [words] => Array         (             [名卡] => Array                 (                     [docs] => 1                     [hits] => 1                 )         ) )完全没问题,搜索出来了,几个关键的操作:[root@beihai365 /]# csft-searchd --stop 停止搜索守护

[root@beihai365 /]# csft-indexer --all 针对所有节点生成索引,你也可以针对某个节点生成索引比如:csft-indexer  xx

[root@beihai365 /]# csft-search App 搜索关键字 App,不过看下面信息没有搜到和没有命中任何的文档.

希望本文所述对大家的php程序设计有所帮助。
