sphinx中文版Coreseek中文检索引擎安装和使用方法(Linux)
众所周知,在MYSQL数据库中,如果你在百万级别数据库中使用 like 的话那你一定在那骂娘,coreseek是一个针对于中文检索方案的一种全文检索技术,基于sphinx开发的。但是在coreseek中不但支持了mysql数据源,还支持了python、xml、mssql、odbc。而且提供了很多语言PHP、C#、JAVA、python等丰富API接口。在中文全文搜索引擎中,基本没有什么能有coreseek匹敌的(是我太深入了嘛-^-),在千万条数据测试下,coreseek生成索引后全文检索的时间不会超过0.5s,这个速度是非常可观的。1. 安装必要的编译工作支持
安装coreseek之前需要安装这些工具,当然使用yum安装你的机子需要先保证已经联网
yum install make gcc g++ gcc-c++ libtool autoconf automake imake mysql-devel libxml2-devel expat-devel
2. 下载coreseek和编译安装
$ wget http://www.coreseek.cn/uploads/csft/3.2/coreseek-3.2.14.tar.gz
$ tar xzvf coreseek-3.2.14.tar.gz
$ cd coreseek-3.2.14
##安装mmseg中文分词
$ cd mmseg-3.2.14
$ ./bootstrap #输出的warning信息可以忽略,如果出现error则需要解决
$ ./configure --prefix=/usr/local/mmseg3
$ make && make install
$ cd ..
##安装coreseek
$ cd csft-3.2.14
$ sh buildconf.sh #输出的warning信息可以忽略,如果出现error则需要解决
$ ./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 ##如果提示mysql问题,可以查看MySQL数据源安装说明,注意--prifix后面的路径要和自己安装的路径一致
$ make && make install
$ cd ..
3. 配置MYSQL数据源
cp /usr/local/coreseek/etc/sphinx.conf.dist /usr/local/coreseek/etc/sphinx.conf
vi /usr/local/coreseek/etc/sphinx.conf
CREATE TABLE sph_counter
(
counter_id INTEGER PRIMARY KEY NOT NULL,
max_doc_id INTEGER NOT NULL
);
source news
{
type = mysql
sql_host = localhost
sql_user = root
sql_pass =123456
sql_db = test
sql_port =3306
sql_sock =/tmp/mysql.sock
sql_query_pre = SET NAMES utf8
sql_query_pre = REPLACE INTO sph_counter SELECT 1, MAX(id) FROM news
sql_query = SELECT id, contents, intro, title FROM news WHERE id<=( SELECT max_doc_id FROM sph_counter WHERE counter_id=1)
}
#设置增量索引,数据量较小时,也可以不设置而定时重新生成索引
source increment : news
{
sql_query_pre = SET NAMES utf8
sql_query = SELECT id, contents, intro, title FROM news WHERE id >( SELECT max_doc_id FROM sph_counter WHERE counter_id=1)
#这是增量索引的数据源sql。和上面保持一致,唯一的变化,就是where条件之后,这里查询的是大于上次重新生成索引的id,即:刚刚添加的数据
}
index news
{
source = news
path =/usr/local/coreseek/var/data/news
docinfo =extern
mlock =0
morphology = none
charset_dictpath =/usr/local/mmseg3/etc/
charset_type = zh_cn.utf-8
}
index increment : news
{
source = increment
path =/usr/local/coreseek/var/data/increment
charset_dictpath =/usr/local/mmseg3/etc/
charset_type = zh_cn.utf-8
}
indexer
{
mem_limit =128M
}
searchd
{
log =/usr/local/coreseek/var/log/searchd.log
read_timeout =5
client_timeout =300
max_children =30
pid_file =/usr/local/coreseek/var/log/searchd.pid
max_matches =1000
seamless_rotate =1
preopen_indexes =0
unlink_old =1
mva_updates_pool =1M
max_packet_size =8M
max_filter_values =4096
}
4.生成索引命令
生成索引
/usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/sphinx.conf --all --rotate
说明:这时sph_counter 表里会增加一条记录。存放的就是你内容表中的最大id。如果想要生成单个数据源的索引, /usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/sphinx.conf news --rotate(这条命令只生成news的索引)
开启后台进程
/usr/local/coreseek/bin/searchd -c /usr/local/coreseek/etc/sphinx.conf
说明:这时候对Mysql数据源进行搜索的话其实已经是有数据的。
增量索引
/usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/sphinx.conf increment --rotate
说明:这里增量索引的名称要换成自己对应的增量索引的名称
合并索引
/usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/sphinx.conf --merge news increment --rotate
为了保持数据的完整性,重新生成索引
/usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/sphinx.conf --all --rotate
5.执行定时任务,更新增量索引、重新生成索引
*/1****/bin/sh /usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/sphinx.conf increment --rotate
*/5****/bin/sh /usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/sphinx.conf --merge news increment --rotate
301*** /bin/sh /usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/sphinx.conf --all --rotate
6.php操作coreseek
复制api/sphinxapi.php文件到你的项目 require ( "sphinxapi.php" ); //这里是直接把api复制到项目的目录中进行使用,也可以安装php的sphinx扩展进行使用,以下会详细介绍php7.0安装sphinx扩展6.php安装sphinx扩展
[第一步] 安装依赖libsphinxclient#cd /usr/local/coreseek-3.2.14/csft-3.2.14/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
# wget http://git.php.net/?p=pecl/search_engine/sphinx.git;a=snapshot;h=9a3d08c67af0cad216aa0d38d39be71362667738;sf=tgz
# tar zxvf sphinx-9a3d08c.tar.gz
# cd sphinx-9a3d08c
# /usr/local/php/bin/phpize
# ./configure --with-php-config=/usr/local/php/bin/php-config --with-sphinx=/usr/local/sphinxclient
# make && make install
extension = sphinx.so
/etc/init.d/php-fpm restart
