一、sphinx的使用原理
(1)先创建数据源。
(2)根据数据源创建索引,使用分词技术
(3)php把查询的关键词给Sphinx服务器,Sphinx根据关键词查找到关键字在mysql表里面的记录的id.Sphinx把id返回给php查询端。
(4)php根据返回的id,查询mysql服务器。
二、从spinx官网下载最新版的sphinx 解压
三、在解压的根目录下新建data 和 log 目录,data目录存储生成的索引文件,log目录存放日志文件
四、在bin目录下新建sphinx.conf文件,这个是sphinx的配置文件,配置信息可参考下面内容,也可自行搜索,把MySQL信息配置及相应的路径配置成自己的即可。
实例
source doc { type = mysql sql_host = localhost sql_user = root sql_pass = 123 sql_db = test sql_port = 3306 sql_query_pre = SET NAMES utf8 sql_query = SELECT id, group_id, UNIX_TIMESTAMP(date_added) AS date_added, title, content FROM documents sql_attr_uint = group_id sql_attr_timestamp = date_added } index testindex { source = doc path = E:/wamp64/www/sphinx/data/testindex mlock = 0 min_word_len = 2 min_prefix_len = 0 min_infix_len = 1 ngram_len = 1 ngram_chars = U+4E00..U+9FBB, U+3400..U+4DB5, U+20000..U+2A6D6, U+FA0E, U+FA0F, U+FA11, U+FA13, U+FA14, U+FA1F, U+FA21, U+FA23, U+FA24, U+FA27, U+FA28, U+FA29, U+3105..U+312C, U+31A0..U+31B7, U+3041, U+3043, U+3045, U+3047, U+3049, U+304B, U+304D, U+304F, U+3051, U+3053, U+3055, U+3057, U+3059, U+305B, U+305D, U+305F, U+3061, U+3063, U+3066, U+3068, U+306A..U+306F, U+3072, U+3075, U+3078, U+307B, U+307E..U+3083, U+3085, U+3087, U+3089..U+308E, U+3090..U+3093, U+30A1, U+30A3, U+30A5, U+30A7, U+30A9, U+30AD, U+30AF, U+30B3, U+30B5, U+30BB, U+30BD, U+30BF, U+30C1, U+30C3, U+30C4, U+30C6, U+30CA, U+30CB, U+30CD, U+30CE, U+30DE, U+30DF, U+30E1, U+30E2, U+30E3, U+30E5, U+30E7, U+30EE, U+30F0..U+30F3, U+30F5, U+30F6, U+31F0, U+31F1, U+31F2, U+31F3, U+31F4, U+31F5, U+31F6, U+31F7, U+31F8, U+31F9, U+31FA, U+31FB, U+31FC, U+31FD, U+31FE, U+31FF, U+AC00..U+D7A3, U+1100..U+1159, U+1161..U+11A2, U+11A8..U+11F9, U+A000..U+A48C, U+A492..U+A4C6 } indexer { mem_limit = 128M } searchd { listen = 9312 listen = 9306:mysql41 log = E:/wamp64/www/sphinx/log/searchd.log query_log = E:/wamp64/www/sphinx/log/query.log read_timeout = 5 max_children = 30 pid_file = E:/wamp64/www/sphinx/log/searchd.pid seamless_rotate = 1 preopen_indexes = 1 unlink_old = 1 workers = threads # for RT to work binlog_path = E:/wamp64/www/sphinx/data }

五、生成索引文件
直接执行indexer.exe这个文件,后面是配置文件里面的索引名称。成功后会在data目录下生成文件
六、启动search服务
七、可以使用api实现全文索引,返回的是符合查询记录的id
实例
<?php require ( "sphinxapi.php" ); $cl = new SphinxClient (); $q = "学习"; //模拟关键字 $sql = ""; $host = "127.0.0.1"; $port = 9312; $index = "*"; $cl->SetServer ( $host, $port ); $cl->SetConnectTimeout(10); $cl->SetArrayResult(true); $res = $cl->Query ( $q, $index ); var_dump($res['matches']);

特别提醒:1、可以修改官方提供的sql记录。添加上中文信息,可以进行中文检索。
2、每次只要修改了MySQL数据库信息,都要从新生成索引文件,也即是执行indexer.exe这个可执行文件从新生成。
