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-</p><p>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 <br />{ <br /> type = mysql <br /> sql_host = localhost <br /> sql_user = root <br /> sql_pass = 1 <br /> sql_db = phpwind75sp3 <br /> sql_port = 3306 # optional, default is 3306 <br /> #sql_sock = /tmp/mysql3307.sock <br /> sql_query_pre = SET NAMES gbk <br /> sql_query = SELECT id,name,type,stock FROM pw_tools <br /> #sql_attr_uint = id <br /> sql_attr_uint = stock <br />} <br /> <br />index tmsgsindex <br />{ <br /> source = tmsgs <br /> path = /var/mmseg/searchdata/beihai365 <br /> docinfo = extern <br /> charset_type = zh_cn.gbk <br /> #min_prefix_len = 0 <br /> #min_infix_len = 2 <br /> #ngram_len = 2 <br /> charset_dictpath = /var/mmseg/data <br /> #min_prefix_len = 0 <br /> #min_infix_len = 0 <br /> #min_word_len = 2 <br />} <br /> <br />indexer <br />{ <br /> mem_limit = 128M <br />} <br /> <br />searchd <br />{ <br /> #listen = 3312 <br /> log = /var/log/searchd.log <br /> query_log = /var/log/query.log <br /> read_timeout = 5 <br /> max_children = 30 <br /> pid_file = /var/log/searchd.pid <br /> max_matches = 1000 <br /> #seamless_rotate = 1 <br /> #preopen_indexes = 0 <br /> #unlink_old = 1 <br />} <br />source tmsgs <br />{ <br /> type = mysql <br /> s<mark>（本文来）源gaodaimacom搞#^代%!码&网(</mark><pre>搞gaodaima代码
ql_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:
<?php <br /> header("Content-type:text/html;charset=utf-8"); <br /> include 'sphinxapi.php'; <br /> $cl = new SphinxClient(); <br /> $cl->SetServer('localhost',3312); <br /> $cl->SetMatchMode(SPH_MATCH_ALL); <br /> $cl->SetArrayResult(true); <br /> $res = $cl->Query("名卡","*"); <br /> print_r($res); <br />?> <br /><?php <br />header("Content-type:text/html;charset=utf-8"); <br />include 'sphinxapi.php'; <br />$cl = new SphinxClient(); <br />$cl->SetServer('localhost',3312); <br />$cl->SetMatchMode(SPH_MATCH_ALL); <br />$cl->SetArrayResult(true); <br />$res = $cl->Query("名卡","*"); <br />print_r($res); <br />?>
“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 <br />( <br /> [error] => <br /> [warning] => <br /> [status] => 0 <br /> [fields] => Array <br /> ( <br /> [0] => name <br /> [1] => type <br /> ) <br /> <br /> [attrs] => Array <br /> ( <br /> [stock] => 1 <br /> ) <br /> <br /> [matches] => Array <br /> ( <br /> [0] => Array <br /> ( <br /> [id] => 8 <br /> [weight] => 1 <br /> [attrs] => Array <br /> ( <br /> [stock] => 100 <br /> ) <br /> ) <br /> ) <br /> [total] => 1 <br /> [total_found] => 1 <br /> [time] => 0.018 <br /> [words] => Array <br /> ( <br /> [名卡] => Array <br /> ( <br /> [docs] => 1 <br /> [hits] => 1 <br /> ) <br /> ) <br />) <br />Array <br />( <br /> [error] => <br /> [warning] => <br /> [status] => 0 <br /> [fields] => Array <br /> ( <br /> [0] => name <br /> [1] => type <br /> ) <br /> [attrs] => Array <br /> ( <br /> [stock] => 1 <br /> ) <br /> [matches] => Array <br /> ( <br /> [0] => Array <br /> ( <br /> [id] => 8 <br /> [weight] => 1 <br /> [attrs] => Array <br /> ( <br /> [stock] => 100 <br /> ) <br /> ) <br /> ) <br /> [total] => 1 <br /> [total_found] => 1 <br /> [time] => 0.018 <br /> [words] => Array <br /> ( <br /> [名卡] => Array <br /> ( <br /> [docs] => 1 <br /> [hits] => 1 <br /> ) <br /> ) <br />)
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.

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。
