sphinx与mysql的配置
创建sphinx统计表,在coreseek_test库中执行。CREATE TABLE sph_counter创建配置sphinx与mysql的配置文件
(
counter_id INTEGER PRIMARY KEY NOT NULL,
max_doc_id INTEGER NOT NULL
);
# vi /usr/local/coreseek/etc/csft_mysql.conf
#MySQL数据源配置,详情请查看:http://www.coreseek.cn/docs/coreseek_4.1-sphinx_2.0.1-beta.html#conf-reference #源定义 source main { type = mysql sql_host = localhost sql_user = root sql_pass = 123456 sql_db = coreseek_test sql_port = 3306 sql_query_pre = SET NAMES utf8 sql_query_pre = REPLACE INTO sph_counter SELECT 1,MAX(id) FROM hr_spider_company; sql_query = SELECT * FROM hr_spider_company WHERE id<=( SELECT max_doc_id FROM sph_counter WHERE counter_id=1 ) #sql_query第一列id需为整数 #title、content作为字符串/文本字段,被全文索引 (注:执行报错的话把下面的几行注释掉) sql_attr_uint = id #从SQL读取到的值必须为整数 sql_attr_uint = from_id #从SQL读取到的值必须为整数,不支持全文检索 sql_attr_uint = link_id #从SQL读取到的值必须为整数,不支持全文检索 sql_attr_uint = add_time #从SQL读取到的值必须为整数,不支持全文检索 sql_field_string = link_url #字符串字段(可全文搜索,可返回原始文本信息) sql_field_string = company_name #字符串字段(可全文搜索,可返回原始文本信息) sql_field_string = type_name #字符串字段(可全文搜索,可返回原始文本信息) sql_field_string = trade_name #字符串字段(可全文搜索,可返回原始文本信息) sql_field_string = email #字符串字段(可全文搜索,可返回原始文本信息) sql_field_string = description #字符串字段(可全文搜索,可返回原始文本信息) sql_query_info_pre = SET NAMES utf8 #命令行查询时,设置正确的字符集 sql_query_info = SELECT id,from_id,link_id,company_name,type_name,trade_name,address,description, FROM_UNIXTIME(add_time) AS add_time FROM hr_spider_company WHERE id=$id #命令行查询时,从数据库读取原始数据信息 } source delta : main { sql_query_pre = SET NAMES utf8 sql_query = SELECT * FROM hr_spider_company WHERE id>( SELECT max_doc_id FROM sph_counter WHERE counter_id=1 ) sql_query_post_index = REPLACE INTO sph_counter SELECT 1,MAX(id) FROM hr_spider_company } #index定义 index main { source = main #对应的source名称 path = /usr/local/coreseek/var/data/mysql #请修改为实际使用的绝对路径,例如:/usr/local/coreseek/var/... docinfo = extern mlock = 0 morphology = none min_word_len = 1 html_strip = 0 #中文分词配置,详情请查看:http://www.coreseek.cn/products-install/coreseek_mmseg/ charset_dictpath = /usr/local/mmseg3/etc/ #BSD、Linux环境下设置,/符号结尾 charset_type = zh_cn.utf-8 } index delta : main { source = delta path = /usr/local/coreseek/var/data/delta } #全局index定义 indexer { mem_limit = 128M } #searchd服务定义 searchd { listen = 9312 read_timeout = 5 max_children = 30 max_matches = 1000 seamless_rotate = 0 preopen_indexes = 0 unlink_old = 1 pid_file = /usr/local/coreseek/var/log/searchd_mysql.pid #请修改为实际使用的绝对路径,例如:/usr/local/coreseek/var/... log = /usr/local/coreseek/var/log/searchd_mysql.log #请修改为实际使用的绝对路径,例如:/usr/local/coreseek/var/... query_log = /usr/local/coreseek/var/log/query_mysql.log #请修改为实际使用的绝对路径,例如:/usr/local/coreseek/var/... binlog_path = #关闭binlog日志 }我的测试表名为hr_spider_company,你只需要根据实际需求更改为自己的表名即可。
调用命令列表:
启动后台服务(必须开启)
# /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)
/usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/csft_mysql.conf --all --rotate
执行增量索引
/usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/csft_mysql.conf delta --rotate
合并索引
/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
# /usr/local/coreseek/bin/search -c /usr/local/coreseek/etc/csft_mysql.conf aaa
关闭后台服务
# /usr/local/coreseek/bin/searchd -c /usr/local/coreseek/etc/csft_mysql.conf --stop自动化命令:
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以下任务计划的意思是:每隔一分钟执行一遍增量索引,每五分钟执行一遍合并索引,每天1:30执行整体索引。
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
# 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
http://pecl.php.net/package/sphinx打开phpinfo看一下是否已经支持了sphinx模块。
# 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调用示例二:支持分页
$s = new SphinxClient;
$s->setServer("127.0.0.1", 9312);
$s->setMatchMode(SPH_MATCH_PHRASE);

$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);

$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];

}
$err = $s->GetLastError();
echo '<pre>';
var_export($res);
var_export($err);

******************************************************************************************************************
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
