Sphinx是一个很好的全文可检索软件,它支持MySQL和PGSQL.
一般来说Sphinx原版对英文全文检索校好,但对中文全文检索的话,就使用国人的修改版coreseek了.
coreseek安装比较麻烦一些.是我的安装记录:
首先下载coreseek源码:
wget http://www.coreseek.cn/uploads/csft/3.2/coreseek-3.2.14.tar.gz
解压:
tar xzvf coreseek-3.2.14.tar.gz
cd coreseek-3.2.14
进入coreseek目录下有三个子目录,分别是mmseg和csft和testpack.需要分别先后安装mmseg和csft.
安装mmseg,中文分词库:
cd mmseg-3.2.14
aclocal
libtoolize --force
automake --add-missing
autoconf
autoheader
make clean #此时如有错误可忽略不管
./configure --prefix=/usr/local/mmseg3
make && make install
在这里先做一点点小优化:
cd data
ln -s /usr/local/mmseg3/mmseg /usr/bin/mmseg
mmseg -u unigram.txt
cp unigram.txt.uni /usr/local/mmseg3/etc/uni.lib
cd ..
回到上级目录:
cd ..
安装csft,也就是coreseek主程序:
cd csft-3.2.14
sh buildconf.sh
./configure --prefix=/usr/local/coreseek --without-python \
--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 ..
这样coreseek就安装好了.
简单测试一下coreseek是否运行正确:
cd ../testpack
/usr/local/coreseek/bin/indexer -c etc/csft.conf
##以下为正常情况下的提示信息：

接着生成索引:
/usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/sphinx.conf --all
完成之后,启动服务进程searchd:
/usr/local/coreseek/bin/searchd -c /usr/local/coreseek/etc/sphinx.conf
到这里,coreseek(shpinx)就已经能正常服务了,下面需要修改一下DZ X2:
登录X2后台,全局=>搜索设置=>启动sphinx作为全文检索,具体配置如下图:
一般地说,到这里就可以完全正常地使用Dz x2的shpinx全文检索功能了.但因为shpinx全文检索功能真的很强,我打算使用全文检索来取代常规搜索.所以还需要修改一个Dz x2的一个搜索程序:
修改source\module\search\search_forum.php
找到$srchtype = empty($_G['gp_srchtype']) ? '' : trim($_G['gp_srchtype']);,并在前面添加一个#号,然后新起一行,添加:$srchtype = empty($_G['gp_srchtype']) ? '' :'fulltext';这样,不管用户有没有选择全文搜索,都是使用sphinx的全文检索功能了.(在这里说一下,原来我使用$srchtype = 'fulltext';后来发现,这样会造成"查看新帖 "功能用不了,今天修复了.)
接着需要配置一下sphinx增量索引:
增量索引:build_delta_index.sh
#!/bin/sh
/usr/local/coreseek/bin/indexer --config /usr/local/coreseek/etc/sphinx.conf threads_minute posts_minute --rotate >> /var/log/sphinx_delta.log
#/usr/local/coreseek/bin/indexer --config /usr/local/coreseek/etc/sphinx.conf --merge threads threads_minute --rotate >> /var/log/sphinx_delta.log
#/usr/local/coreseek/bin/indexer --config /usr/local/coreseek/etc/sphinx.conf --merge posts posts_minute --rotate >> /var/log/sphinx_delta.log
注意后面两行的#号,原来我打算在处理增量索引的同时,执行一下索引合并的,但是,考虑一是由于现有的贴子数有230百万左右,每次合并都要花很长的时候,第二,由于sphinx在合并时,对于重复的记录并不会删除,而只是添加一个新记录,这样,索引文件的体积就会X2.现在的索引文件已经用了几十个G了,再X2那就没必要了.还好,DZ X2 会从主索引和增量索引去检索,所以我只是每天合并一次增量索引.目前看来,运行良好.
合并增量索引:merge_delta_index.sh
#!/bin/sh
/usr/local/coreseek/bin/indexer --config /usr/local/coreseek/etc/sphinx.conf --merge threads threads_minute --rotate >> /var/log/sphinx_delta.log
/usr/local/coreseek/bin/indexer --config /usr/local/coreseek/etc/sphinx.conf --merge posts posts_minute --rotate >> /var/log/sphinx_delta.log
主索引:build_main_index.sh
#!/bin/sh
/usr/local/coreseek/bin/indexer --config /usr/local/coreseek/etc/sphinx.conf threads posts --rotate >> /var/log/sphinx_main.log
Cron定时更新索引:
crontab -e
*/5 * * * * /root/build_delta_index.sh > /dev/null 2 >&1
0 3 * * * 1-6 /root/merge_delta_index.sh > /dev/null 2 >&1
0 3 * * 0 /root/build_main_index.sh > /dev/null 2 >&1
保存退出.
安装Sphinx过程中遇到的一些问题和解决方法:
/usr/local/coreseek/bin/search --config /usr/local/sphinx/etc/sphinx.conf
/usr/local/sphinx/bin/indexer: error while loading shared libraries: libmysqlclient.so.16: cannot open shared object file: No such file or directory
这个是因为coreseek(Sphinx)找不到 libmysqlclient.so引起的,解决方法:
vi /etc/ld.so.conf
在最后面添加一行:
/usr/lib/mysql
ldconfig
./bootstrap: line 23: aclocal: command not found
./bootstrap: line 24: libtoolize: command not found
需要安装 libtoo libtool,解决方法:
yum install autoconf automake libtoo libtool
WARNING: source 'xml': xmlpipe2 support NOT compiled in. To use xmlpipe2, install missing XML libraries, reconfigure, and rebuild Sphinx
需要安装libxml2,解决方法:
yum install libxml2
然后重新编译coreseek(Sphinx)
如果提示不支持charset_table的话,很可能你是运行标准版的Shpinx而不是coreseek,只有coreseek才支持这个属性.运行正常的coreseek路径就可以了.
一般来说Sphinx原版对英文全文检索校好,但对中文全文检索的话,就使用国人的修改版coreseek了.
coreseek安装比较麻烦一些.是我的安装记录:
首先下载coreseek源码:
wget http://www.coreseek.cn/uploads/csft/3.2/coreseek-3.2.14.tar.gz
解压:
tar xzvf coreseek-3.2.14.tar.gz
cd coreseek-3.2.14
进入coreseek目录下有三个子目录,分别是mmseg和csft和testpack.需要分别先后安装mmseg和csft.
安装mmseg,中文分词库:
cd mmseg-3.2.14
aclocal
libtoolize --force
automake --add-missing
autoconf
autoheader
make clean #此时如有错误可忽略不管
./configure --prefix=/usr/local/mmseg3
make && make install
在这里先做一点点小优化:
cd data
ln -s /usr/local/mmseg3/mmseg /usr/bin/mmseg
mmseg -u unigram.txt
cp unigram.txt.uni /usr/local/mmseg3/etc/uni.lib
cd ..
回到上级目录:
cd ..
安装csft,也就是coreseek主程序:
cd csft-3.2.14
sh buildconf.sh
./configure --prefix=/usr/local/coreseek --without-python \
--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 ..
这样coreseek就安装好了.
简单测试一下coreseek是否运行正确:
cd ../testpack
/usr/local/coreseek/bin/indexer -c etc/csft.conf
##以下为正常情况下的提示信息：

接着生成索引:
/usr/local/coreseek/bin/indexer -c /usr/local/coreseek/etc/sphinx.conf --all
完成之后,启动服务进程searchd:
/usr/local/coreseek/bin/searchd -c /usr/local/coreseek/etc/sphinx.conf
到这里,coreseek(shpinx)就已经能正常服务了,下面需要修改一下DZ X2:
登录X2后台,全局=>搜索设置=>启动sphinx作为全文检索,具体配置如下图:
一般地说,到这里就可以完全正常地使用Dz x2的shpinx全文检索功能了.但因为shpinx全文检索功能真的很强,我打算使用全文检索来取代常规搜索.所以还需要修改一个Dz x2的一个搜索程序:
修改source\module\search\search_forum.php
找到$srchtype = empty($_G['gp_srchtype']) ? '' : trim($_G['gp_srchtype']);,并在前面添加一个#号,然后新起一行,添加:$srchtype = empty($_G['gp_srchtype']) ? '' :'fulltext';这样,不管用户有没有选择全文搜索,都是使用sphinx的全文检索功能了.(在这里说一下,原来我使用$srchtype = 'fulltext';后来发现,这样会造成"查看新帖 "功能用不了,今天修复了.)
接着需要配置一下sphinx增量索引:
增量索引:build_delta_index.sh
#!/bin/sh
/usr/local/coreseek/bin/indexer --config /usr/local/coreseek/etc/sphinx.conf threads_minute posts_minute --rotate >> /var/log/sphinx_delta.log
#/usr/local/coreseek/bin/indexer --config /usr/local/coreseek/etc/sphinx.conf --merge threads threads_minute --rotate >> /var/log/sphinx_delta.log
#/usr/local/coreseek/bin/indexer --config /usr/local/coreseek/etc/sphinx.conf --merge posts posts_minute --rotate >> /var/log/sphinx_delta.log
注意后面两行的#号,原来我打算在处理增量索引的同时,执行一下索引合并的,但是,考虑一是由于现有的贴子数有230百万左右,每次合并都要花很长的时候,第二,由于sphinx在合并时,对于重复的记录并不会删除,而只是添加一个新记录,这样,索引文件的体积就会X2.现在的索引文件已经用了几十个G了,再X2那就没必要了.还好,DZ X2 会从主索引和增量索引去检索,所以我只是每天合并一次增量索引.目前看来,运行良好.
合并增量索引:merge_delta_index.sh
#!/bin/sh
/usr/local/coreseek/bin/indexer --config /usr/local/coreseek/etc/sphinx.conf --merge threads threads_minute --rotate >> /var/log/sphinx_delta.log
/usr/local/coreseek/bin/indexer --config /usr/local/coreseek/etc/sphinx.conf --merge posts posts_minute --rotate >> /var/log/sphinx_delta.log
主索引:build_main_index.sh
#!/bin/sh
/usr/local/coreseek/bin/indexer --config /usr/local/coreseek/etc/sphinx.conf threads posts --rotate >> /var/log/sphinx_main.log
Cron定时更新索引:
crontab -e
*/5 * * * * /root/build_delta_index.sh > /dev/null 2 >&1
0 3 * * * 1-6 /root/merge_delta_index.sh > /dev/null 2 >&1
0 3 * * 0 /root/build_main_index.sh > /dev/null 2 >&1
保存退出.
安装Sphinx过程中遇到的一些问题和解决方法:
/usr/local/coreseek/bin/search --config /usr/local/sphinx/etc/sphinx.conf
/usr/local/sphinx/bin/indexer: error while loading shared libraries: libmysqlclient.so.16: cannot open shared object file: No such file or directory
这个是因为coreseek(Sphinx)找不到 libmysqlclient.so引起的,解决方法:
vi /etc/ld.so.conf
在最后面添加一行:
/usr/lib/mysql
ldconfig
./bootstrap: line 23: aclocal: command not found
./bootstrap: line 24: libtoolize: command not found
需要安装 libtoo libtool,解决方法:
yum install autoconf automake libtoo libtool
WARNING: source 'xml': xmlpipe2 support NOT compiled in. To use xmlpipe2, install missing XML libraries, reconfigure, and rebuild Sphinx
需要安装libxml2,解决方法:
yum install libxml2
然后重新编译coreseek(Sphinx)
如果提示不支持charset_table的话,很可能你是运行标准版的Shpinx而不是coreseek,只有coreseek才支持这个属性.运行正常的coreseek路径就可以了.
Memcache的安装(Linux+Nginx+PHP+Memcached)
