sphinx与mysql的配置
创建sphinx统计表,在coreseek_test库中执行。
-
CREATE TABLE sph_counter
-
(
-
counter_id INTEGER PRIMARY KEY NOT NULL,
-
max_doc_id INTEGER NOT NULL
-
);
创建配置sphinx与mysql的配置文件
-
# 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
-

-
min_word_len = 1
-
html_strip = 0

charset_dictpath = /usr/local/mmseg3/etc/ #BSD、Linux环境下设置,/符号结尾
-

-
}
-

-

seamless_rotate = 0

-
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:
-
*/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=====>./configure --prefix=/usr/local/sphinxclient
-
-
# make && make install
[第二步] 安装sphinx的PHP扩展
-
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======================>根据自己PHP安装文件来确定,比如我的安装地址是 /usr/local/php/bin/phpize
-
-
# ./configure --with-php-config=/usr/bin/php-config --with-sphinx=/usr/local/sphinxclient
-
我自己执行的是 ./configure --with-php-config=/usr/local/php/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
打开phpinfo看一下是否已经支持了sphinx模块。
php调用sphinx示例:
-
<?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>';
调用示例二:支持分页
-
<?php
-
header("Content-type: text/html; charset=utf-8");
-
require("./sphinxapi.php");
-
$s = new SphinxClient;
-
$s->setServer("192.168.252.132", 9312);
-
-
-
$s->setMatchMode(SPH_MATCH_ALL);
-
$s->setMaxQueryTime(30);
-
$s->SetArrayResult(false);
-
$s->SetSelect ( "*" );
-
$s->SetRankingMode(SPH_RANK_BM25);
-
-
-
$weights = array ('company_name' => 20);
-
$s->SetFieldWeights($weights);
-
$s->SetLimits ( 0, 30, 1000, 0 );
-
-
-
$res = $s->query('@* "汽车"','main','--single-0-query--'); #[宝马]关键字,[news]数据源source
-
-
-
-
$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() );
-
$description = $s->BuildExcerpts ($description, 'main', '汽车', $opts=array() );
-
foreach($tags as $k=>$v)
-
{
-
$tags[$k]['company_name'] = $company_name[$k];
-
$tags[$k]['description'] = $description[$k];
-
}
-
-
-
$i = 0;
-
foreach($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
