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,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_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:
- <?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
- Copyright (c) 2006-2008 coreseek.com
- 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。
