#接下来实现数据源支持:让sphinx支持MySQL数据源

yum -y install mysql-devel libxml2-devel expat-devel
cd /data/src/coreseek-4.1-beta/csft-4.1/
make clean
sh buildconf.sh
 ./configure --prefix=/usr/local/coreseek  --without-unixodbc --with-mmseg --with-mmseg-includes=/usr/local/mmseg3/include/mmseg/ --with-mmseg-libs=/usr/local/mmseg3/lib/ --with-mysql
make && make install
cd ../

##如果出现错误提示:“ERROR: cannot find MySQL include files…….To disable MySQL support, use –without-mysql option.“,可按照如下方法处理:
##请找到头文件mysql.h所在的目录,一般是/usr/local/mysql/include,请替换为实际的
##请找到库文件libmysqlclient.a所在的目录,一般是/usr/local/mysql/lib,请替换为实际的
##configure参数加上:–with-mysql-includes=/usr/local/mysql/include –with-mysql-libs=/usr/local/mysql/lib,执行后,重新编译安装
#跑sphinx服务脚本
/data/sh/other/sphinx_update_index.sh

好了,如果一切正常,将会顺利看到创建索引的信息如下:
【原创】用coreseek快速搭建sphinx中文分词搜索引擎

下面写一段php代码进行测试(基于sphinx php 的api方式):

		$page = (int)$_GET['page'];
		$page = ($page==0)?1:$page;
		$perpage = 200;
		$start = ($page -1) * $perpage;
		$keyword = urldecode($_GET['key']);
		require_once (S_ROOT . './api/sphinxapi.php');//请改成您的真实路径
 		$groupby = "";
		$groupsort = "@group desc";
		$filter = "fieldid";
		$filtervals = array ();
		$distinct = "";
		$sortby = "";
		$cl = new SphinxClient();
		$cl->SetServer("localhost", 3312);
		$cl->SetWeights(array (
				100,
				1
		));
		$cl->SetMatchMode(SPH_MATCH_ANY);
		if (count($filtervals)) {
				$cl->SetFilter($filter, $filtervals);
		}
		if ($groupby) {
				$cl->SetGroupBy($groupby, SPH_GROUPBY_ATTR, $groupsort);
		}
		$order = 1;
		if ($order == 0) { //按时间倒序
				$cl->SetSortMode(SPH_SORT_ATTR_DESC, "inputtime");
		}
		elseif ($order == 1) { //按相关度排序
				$cl->SetSortMode(SPH_SORT_RELEVANCE);
		}
		if ($distinct) {
				$cl->SetGroupDistinct($distinct);
		}
		$cl->SetLimits($start, $perpage, ($limit > 1000) ? $limit : 1000);
		$cl->SetRankingMode(SPH_RANK_PROXIMITY_BM25);
		$cl->SetArrayResult(true);
		$res = $cl->Query($keyword, 'cc_phpcms');
		print_r($res);die;

上面的php代码没有做输入的字符过滤,这个请按自己的需要加上。
另外,
/data/sh/other/sphinx_update_index.sh 跑了一次后,

vi /data/sh/other/sphinx_update_index.sh

#/usr/local/coreseek/bin/indexer --config ${CONFFILE}.2 --all --rotate
/usr/local/coreseek/bin/indexer --config ${CONFFILE}.2 --all

变成

/usr/local/coreseek/bin/indexer --config ${CONFFILE}.2 --all --rotate
#/usr/local/coreseek/bin/indexer --config ${CONFFILE}.2 --all

也就是将注释调换,这样以后就可以设定个定时计划跑/data/sh/other/sphinx_update_index.sh 脚本了,
跑了/sphinx_update_index.sh 脚本后,自动会用–rotate的方式重建索引,也就是说新增加的内容也将会被索引到了。

当然,最好的方法还是做个实时索引的配置,下一篇将会重点介绍sphinx的实时索引功能!
