phpcms中使用sphinx全文索引教程

phpcms sphinx全文索引教程

英文介绍：http://www.sphinxsearch.com/docs/manual-0.9.9.html

一、首先需要在服务器上安装sphinx

在Windows上安装sphinx

1.下载支持mysql的包  http://www.sphinxsearch.com/downloads/sphinx-0.9.9-win32.zip
2.解压缩 sphinx-0.9.9-win32.zip 到 D:＼sphinx
3.安装sphinx服务，在命令行执行命令

  D:＼sphinx＼searchd –install –config d:＼sphinx＼sphinx.conf –servicename SphinxSearch
英文参照：http://www.sphinxsearch.com/docs … #installing-windows

1.下载源码包 http://www.sphinxsearch.com/downloads/sphinx-0.9.9.tar.gz

  $ tar xzvf sphinx-0.9.8.tar.gz
$ cd sphinx
$ ./configure –prefix=/usr/local/sphinx –with-mysql=/usr/local/mysql
$ make
$ make install

常见问题1

 
/usr/local/sphinx-0.9.9/src/sphinx.cpp:20060: undefined reference to libiconv_open'
/usr/local/sphinx-0.9.9/src/sphinx.cpp:20078: undefined reference to libiconv‘
/usr/local/sphinx-0.9.9/src/sphinx.cpp:20084: undefined reference to libiconv_close'
collect2: ld returned 1 exit status
make[2]: *** [indexer] Error 1
make[2]: Leaving directory /home/jling/sphinx-0.9.9/src’
make[1]: *** [all] Error 2
make[1]: Leaving directory `/home/jling/sphinx-0.9.9/src‘
make: *** [all-recursive] Error 1
解决办法：打开configure文件，找到“#define USE_LIBICONV 1”，将注释去掉，并将1改成0。

常见问题2

 
error while loading shared libraries: libmysqlclient.so.16: cannot open shared object file: No such file or directory
解决办法：

 
64位系统ln -s /usr/local/webserver/mysql/lib/mysql/libmysqlclient.so.16.0.0 /usr/lib64/libmysqlclient.so.16
32位系统ln -s /usr/local/webserver/mysql/lib/mysql/libmysqlclient.so.16.0.0 /usr/lib/libmysqlclient.so.16

sql_query_pre = REPLACE INTO v9_sphinx_counter SELECT 1, MAX(searchid) FROM v9_search
sql_query = SELECT searchid, adddate, siteid, typeid, id, data FROM v9_search ＼
WHERE searchid>=$start AND searchid<=$end
sql_query_range  = SELECT 1,max_doc_id FROM v9_sphinx_counter WHERE counter_id=1
sql_range_step = 5000

  #字符串属性设置、需要过滤、排序的时候用到
sql_attr_uint  = typeid
sql_attr_uint  = siteid
sql_attr_uint  = id
sql_attr_timestamp  = adddate
sql_query_info  = SELECT * FROM v9_search WHERE searchid=$id

 source delta

sql_attr_uint  = siteid
sql_attr_uint  = id
sql_attr_timestamp  = adddate

}

 #主索引

ngram_len = 1
# 需要分词的字符，如果要搜索中文，去掉前面的注释
ngram_chars   = U+3000..U+2FA1F
}

 #增量索引

index delta
{
source = delta

 indexer

附件：设置计划任务更新索引

1.windows下

需要设置计划任务
#凌晨4点合并索引，执行merge.bat
#其余时间每分钟更新索引，执行delta.bat

merge.bat

@ECHO off

D:＼sphinx＼bin＼indexer.exe –config D:＼sphinx＼sphinx.conf –merge main delta –rotate

echo indexing, window will close when complete
 

delta.bat

 @ECHO off
D:＼sphinx＼bin＼indexer.exe –config D:＼sphinx＼sphinx.conf delta –rotate
echo indexing, window will close when complete
2.linux下编辑定时任务 crontab -e

 
#凌晨4点合并索引，其余时间每分钟更新索引
* 0-3 * * * /usr/local/sphinx/bin/indexer –config /usr/local/sphinx/etc/sphinx.conf delta –rotate
* 6-23 * * * /usr/local/sphinx/bin/indexer –config /usr/local/sphinx/etc/sphinx.conf delta –rotate
0 4 * * * /usr/local/sphinx/bin/indexer –config /usr/local/sphinx/etc/sphinx.conf –merge main delta –rotate
各种路径、权限需要应用所在服务器一致，如：
sphinx.conf 中需要配置
sql_host 数据库主机地址
sql_user 数据库用户名
sql_pass 数据库密码
sql_db 数据库名
sql_port 数据库端口
phpcms表前缀样例中为phpcms_
索引路径 D:＼sphinx＼data＼delta
