sphinx与mysql的配置
创建sphinx统计表,在coreseek_test库中执行。[sql] view plain copy
- CREATE TABLE sph_counter
- (
- counter_id INTEGER PRIMARY KEY NOT NULL,
- max_doc_id INTEGER NOT NULL
- );
[plain] view plain copy
- # vi /usr/local/coreseek/etc/csft_mysql.conf

调用命令列表:
启动后台服务(必须开启)
[plain] view plain copy- # /usr/local/coreseek/bin/searchd -c /usr/local/coreseek/etc/csft_mysql.conf
执行索引(查询、测试前必须执行一次)
[plain] view plain copy- /usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/csft_mysql.conf --all --rotate
执行增量索引
[plain] view plain copy- /usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/csft_mysql.conf delta --rotate
合并索引
[plain] view plain copy- /usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/csft_mysql.conf --merge main delta --rotate --merge-dst-range deleted 0 0
(为了防止多个关键字指向同一个文档加上--merge-dst-range deleted 0 0)
后台服务测试
[plain] view plain copy- # /usr/local/coreseek/bin/search -c /usr/local/coreseek/etc/csft_mysql.conf aaa
关闭后台服务
[plain] view plain copy- # /usr/local/coreseek/bin/searchd -c /usr/local/coreseek/etc/csft_mysql.conf --stop
- crontab -e
- */1 * * * * /bin/sh /usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/csft_mysql.conf delta --rotate
- */5 * * * * /bin/sh /usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/csft_mysql.conf --merge main delta --rotate --merge-dst-range deleted 0 0
- 30 1 * * * /bin/sh /usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/csft_mysql.conf --all --rotate
Sphinx扩展安装安装
Coreseek官方教程中建议php使用直接include一个php文件进行操作,事实上php有独立的sphinx模块可以直接操作coreseek(coreseek就是sphinx!)已经进入了php的官方函数库,而且效率的提升不是一点点!但php模块依赖于libsphinxclient包。[第一步] 安装依赖libsphinxclient
[plain] view plain copy- # cd /var/install/coreseek-4.1-beta/csft-4.1/api/libsphinxclient/
- # ./configure --prefix=/usr/local/sphinxclient
- configure: creating ./config.status
- config.status: creating Makefile
- config.status: error: cannot find input file: Makefile.in #报错configure失败
- //处理configure报错
- 编译过程中报了一个config.status: error: cannot find input file: src/Makefile.in这个的错误,然后运行下列指令再次编译就能通过了:
- # aclocal
- # libtoolize --force
- # automake --add-missing
- # autoconf
- # autoheader
- # make clean
- //从新configure编译
- # ./configure
- # make && make install
[第二步] 安装sphinx的PHP扩展
[plain] view plain copy- http://pecl.php.net/package/sphinx
- # wget http://pecl.php.net/get/sphinx-1.3.0.tgz
- # tar zxvf sphinx-1.3.0.tgz
- # cd sphinx-1.3.0
- # phpize
- # ./configure --with-php-config=/usr/bin/php-config --with-sphinx=/usr/local/sphinxclient
- # make && make install
- # cd /etc/php.d/
- # cp gd.ini sphinx.ini
- # vi sphinx.ini
- extension=sphinx.so
- # service php-fpm restart
php调用sphinx示例:
[php] view plain copy- <?php
- $s = new SphinxClient;
- $s->setServer("127.0.0.1", 9312);
- $s->setMatchMode(SPH_MATCH_PHRASE);
- $s->setMaxQueryTime(30);
- $res = $s->query("宝马",'main'); #[宝马]关键字,[main]数据源source
- $err = $s->GetLastError();
- var_dump(array_keys($res['matches']));
- echo "<br>"."通过获取的ID来读取数据库中的值即可。"."<br>";
- echo '<pre>';
- var_dump($res);
- var_dump($err);
- echo '</pre>';
[php] view plain copy
- <?php
- header("Content-type: text/html; charset=utf-8");
- require("./sphinxapi.php");
- $s = new SphinxClient;
- $s->setServer("192.168.252.132", 9312);
- //SPH_MATCH_ALL, 匹配所有查询词(默认模式); SPH_MATCH_ANY, 匹配查询词中的任意一个; SPH_MATCH_EXTENDED2, 支持特殊运算符查询
- $s->setMatchMode(SPH_MATCH_ALL);
- $s->setMaxQueryTime(30); //设置最大搜索时间
- $s->SetArrayResult(false); //是否将Matches的key用ID代替
- $s->SetSelect ( "*" ); //设置返回信息的内容,等同于SQL
- $s->SetRankingMode(SPH_RANK_BM25); //设置评分模式,SPH_RANK_BM25可能使包含多个词的查询的结果质量下降。
- //$s->SetSortMode(SPH_SORT_EXTENDED); //发现增加此参数会使结果不准确
- //$s->SetSortMode(SPH_SORT_EXTENDED,"from_id asc,id desc"); //设置匹配项的排序模式, SPH_SORT_EXTENDED按一种类似SQL的方式将列组合起来,升序或降序排列。
- $weights = array ('company_name' => 20);
- $s->SetFieldWeights($weights); //设置字段权重
- $s->SetLimits ( 0, 30, 1000, 0 ); //设置结果集偏移量 SetLimits (便宜量,匹配项数目,查询的结果集数默认1000,阀值达到后停止)
- //$s->SetFilter ( $attribute, $values, $exclude=false ); //设置属性过滤
- //$s->SetGroupBy ( $attribute, $func, $groupsort="@group desc" ); //设置分组的属性
- $res = $s->query('@* "汽车"','main','--single-0-query--'); #[宝马]关键字,[news]数据源source
- //代码高亮
- $tags = array();
- $tags_name = array();
- foreach($res['matches'] as $key=>$value){
- $tags[] = $value['attrs'];
- $company_name[] = $value['attrs']['company_name'];
- $description[] = $value['attrs']['description'];
- }
- $company_name = $s->BuildExcerpts ($company_name, 'main', '汽车', $opts=array() ); //执行高亮,这里索引名字千万不能用*
- $description = $s->BuildExcerpts ($description, 'main', '汽车', $opts=array() ); //执行高亮,这里索引名字千万不能用*
- foreach($tags as $k=>$v)
- {
- $tags[$k]['company_name'] = $company_name[$k]; //高亮后覆盖
- $tags[$k]['description'] = $description[$k]; //高亮后覆盖
- }
- // 高亮后覆盖
- $i = 0;
- foreach($res['matches'] as $key=>$value){
- $res['matches'][$key] = $tags[$i];
- $i++;
- }
- $err = $s->GetLastError();
- echo '<pre>';
- var_export($res);
- var_export($err);
- echo '</pre>';
******************************************************************************************************************
错误:FATAL: failedto lock pid file '/home/zhangjie_z.pt/local/sphinx/var/log/searchd.pid':Resource temporarily unavailable (searchd already running?)
意思就是你已经打开了一个search进程,你需要找到相关进程号ps -e|grep searchd,然后kill PID杀死之前的进程,再启动新进程)
启动 searchd 服务时提示如下错误:
index 'test1': search error: failed to open /var/lib/sphinx/test1.sph: sphinx 错误解决 index 'test1': search error: failed to open /var/lib/sphinx/test.sph:No such file or directory; NOT SERVING
这个错误可能是没有建立好索引导致的,所以 indexer --all 很重要
