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:

[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:

source tmsgs    

{    

        type                                    = mysql    

        sql_host                                = localhost    

        sql_user                                = root    

        sql_pass                                = 1

        sql_attr_uint                           = stock    

}

        source                                  = tmsgs    

        path                                    = /var/mmseg/searchdata/beihai365

        #min_prefix_len                          = 0    

        #min_infix_len                           = 0    

        #min_word_len                            = 2    

}

{    

        mem_limit                               = 128M    

}

{    

        #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_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

        #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:

<?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:

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.

Coreseek Full Text Server 3.1

当大家在运行这些命令的时候发现,需要你自己手动的置顶 --config  sphinx.conf   配置文件的路径,很不方便,所以我干脆 ln -s 一个在 ./,这样不用每次都去敲入  --config.

希望本文所述对大家的php程序设计有所帮助。
