sphinx 全文索引教程
Sphinx是一个基于SQL的全文检索引擎,可以结合MySQL,PostgreSQL做全文搜索,它可以提供比数据库本身更专业的搜索功能,使得应用程序更容易实现专业化的全文检索。Sphinx特别为一些脚本语言设计搜索API接口,如PHP,Python,Perl,Ruby等,同时为MySQL也设计了一个存储引擎插件。
PHPCMS V9支持这一技术,当然我们需要事先在服务器上做一些相应的部署

一、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
在Linux服务器上安装sphinx
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
问题一
/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
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。
问题二
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
sphinx.conf样例
source main { type = mysql #数据库类型 sql_host = 10.228.134.211 #数据库ip sql_user = admin #数据库用户名 sql_pass = admin #数据库密码 sql_db = phpcms_v9 #数据库名 sql_port = 3306 # 数据库端口 sql_query_pre = SET NAMES utf8 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>=$start AND searchid( SELECT max_doc_id FROM v9_sphinx_counter WHERE counter_id=1 ) sql_query_post = REPLACE INTO v9_sphinx_counter SELECT 1, MAX(searchid) FROM v9_search #字符串属性设置、需要过滤、排序的时候用到 sql_attr_uint = typeid sql_attr_uint = siteid sql_attr_uint = id sql_attr_timestamp = adddate sql_query_info = SELECT * FROM v9_search WHERE searchid=$id } #主索引 index main { source = main # 放索引的目录 path = D:\sphinx\data\main # 编码 charset_type = utf-8 # 指定utf-8的编码表 charset_table = 0..9, A..Z->a..z, _, a..z, U+410..U+42F->U+430..U+44F, U+430..U+44F # 简单分词,只支持0和1,如果要搜索中文,请指定为1 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 path = D:\sphinx\data\delta # 编码 charset_type = utf-8 # 指定utf-8的编码表 charset_table = 0..9, A..Z->a..z, _, a..z, U+410..U+42F->U+430..U+44F, U+430..U+44F # 简单分词,只支持0和1,如果要搜索中文,请指定为1 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 } indexer { mem_limit = 128M } searchd { port = 9312 log = D:\sphinx\data\phpcms\searchd.log query_log = D:\sphinx\data\phpcms\query.log read_timeout = 5 max_children = 30 pid_file = D:\sphinx\data\phpcms\searchd.pid max_matches = 2000 seamless_rotate = 0 preopen_indexes = 0 unlink_old = 1 }
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
