这篇文章主要介绍了php启用sphinx全文搜索的实现方法,详细讲述了sphinx相关的配置与使用技巧,具有一定的参考借鉴价值,需要的朋友可以参考下

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,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:

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:

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_.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_.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:
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:
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 --s 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,不过看狼蚁网站SEO优化信息没有搜到和没有命中任何的文档.

using config file './csft.conf'...
1,
pt:1, 1;        index 'tmsgsindex': query 'App ': returned 0 matches of 0 total in 0.017 sec
words:
1. 'app': 0 documents, 0 hits
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。
