coreseek3.2.14全文搜索引擎安装使用

下载coreseek 3.2.14

wget http://www.coreseek.cn/uploads/csft/3.2/coreseek-3.2.14.tar.gz

wget http://pecl.php.net/get/sphinx-1.3.2.tgz #sphinx扩展

coreseek安装需要预装的软件:

yum install make gcc g++ gcc-c++ libtool autoconf automake imake mysql-devel libxml2-devel expat-devel

安装xmlpipe2支持(如果上面已安装可以不用再安装)
[root@localhost tools]#yum  -y install expat-devel*
[root@localhost tools]#tar -xzvf coreseek-3.2.14.tar.gz

[root@localhost tools]#cd coreseek-3.2.14

安装中文分词插件mmseg-3.2.14
[root@localhost coreseek-3.2.14]#cd mmseg-3.2.14

[root@localhost mmseg-3.2.14]# ./configure --prefix=/usr/local/mmseg3

安装时如果出现
config.status: error: cannot find input file: src/Makefile.in

可以通过安装autoconf和automake解决

[root@localhost mmseg-3.2.14]#yum -y install autoconf automake

[root@localhost mmseg-3.2.14]#aclocal
如果出现下面错误:
configure.in:26: warning: macro `AM_PROG_LIBTOOL' not found in library

[root@localhost mmseg-3.2.14]#yum -y install libtool
[root@localhost mmseg-3.2.14]#aclocal
[root@localhost mmseg-3.2.14]# libtoolize --force

libtoolize: putting auxiliary files in AC_CONFIG_AUX_DIR, `config'.
libtoolize: linking file `config/ltmain.sh'
libtoolize: Consider adding `AC_CONFIG_MACRO_DIR([m4])' to configure.in and
libtoolize: rerunning libtoolize, to keep the correct libtool macros in-tree.
libtoolize: Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile.am.

[root@localhost mmseg-3.2.14]# automake --add-missing

[root@localhost mmseg-3.2.14]# autoconf

[root@localhost mmseg-3.2.14]# autoheader

[root@localhost mmseg-3.2.14]# make clean

[root@localhost mmseg-3.2.14]# ./configure --prefix=/usr/local/mmseg3

[root@localhost mmseg-3.2.14]# make && make install

[root@localhost mmseg-3.2.14]# ln -s /usr/local/mmseg3/bin/mmseg /bin/mmseg

接下来安装Coreseek 3.2.14
[root@localhost mmseg-3.2.14]# cd ..

[root@localhost coreseek-3.2.14]# cd csft-3.2.14

[root@localhost csft-3.2.14]# ./configure --prefix=/usr/local/coreseek --without-unixodbc --with-mmseg-includes=/usr/local/mmseg3/include/mmseg/ --with-mmseg-libs=/usr/local/mmseg3/lib/ --with-mysql

[root@localhost csft-3.2.14]# make && make install

安装sphinx扩展模块
1)安装libsphinxclient依赖包

[root@localhost coreseek-3.2.14]#cd api/libsphinxclient

[root@localhost libsphinxclient]#./configure

[root@localhost libsphinxclient]# make && make install

2)安装PHP扩展
[root@localhost coreseek-3.2.14]# tar -xzvf sphinx-1.3.2.tgz
[root@localhost coreseek-3.2.14]# cd sphinx-1.3.2

[root@localhost sphinx-1.3.2]# /usr/local/php/bin/phpize

[root@localhost sphinx-1.3.2]# ./configure --with-php-config=/usr/local/php/bin/php-config --with-sphinx

[root@localhost sphinx-1.3.2]# make && make install
修改PHP配置文件,添加sphinx扩展
[root@localhost sphinx-1.3.2]# vi /usr/local/php/etc/php.ini
添加extension=sphinx.so
保存退出
重启PHP
/etc/init.d/php-fpm restart

测试coreseek中文分词
cd coreseek-3.2.14/testpack/
/usr/local/mmseg3/bin/mmseg -d /usr/local/mmseg3/etc var/test/test.xml

显示

make[2]: *** [sphinx.o] Error 1

make[1]: *** [all] Error 2
make[1]: Leaving directory `/root/tools/coreseek-3.2.14/csft-3.2.14/src'
make: *** [all-recursive] Error 1

官网解决办法:

In the meantime I've change the configuration file and set
#define USE_LIBICONV 0 in line 8179.
修改configure 文件把 #define USE_LIBICONV 0 最后的数值由1改为0
make && make install

错误二:
make[2]: *** [indexer] Error 1
make[2]: Leaving directory `/www/tmp/csft-3.1/src'
make[1]: *** [all] Error 2
make[1]: Leaving directory `/www/tmp/csft-3.1/src'
make: *** [all-recursive] Error 1

解决办法

vi ./src/sphinx.cpp

注释以下代码

#case TOKENIZER_ZHCN_GBK:
#pTokenizer = sphCreateGBKChineseTokenizer
#(tSettings.m_sDictPath.cstr(), tSettings.m_nBest); break;
然后重新编译
make clean
make && make install

错误三:索引不生成
/usr/local/coreseek/bin/indexer -c etc/csft.conf -all
改为
/usr/local/coreseek/bin/indexer -c etc/csft.conf --all

下面开始配置coreseek
cd /usr/local/coreseek/etc
cp sphinx-min.conf.dist csft.conf
vi csft.conf
