Sphinx安装及应用
一．安装
参考http://www.coreseek.cn/docs/coreseek_4.1-sphinx_2.0.1-beta.html#supported-system
$ tar xzvf sphinx-2.0.1-beta.tar.gz
$ cd sphinx
1.首先安装MMSeg:
$ cd mmseg
$ ./configure --prefix=/usr/local/mmseg
$ make
$ make install
$ cd ..
2.运行配置程序:
$ ./configure
configure程序有很多运行选项。完整的列表可以通过使用 --help 开关得到。最重要的如下：
--prefix, 定义将Coreseek安装到何处;比如--prefix=/usr/local/sphinx(以下全部示例都假定Coreseek安装在这个位置)
--with-mysql, 当自动检测失败时，需要指出在那里能找到MySQL 头文件和库文件;
--with-pgsql指出在那里能找到PostgreSQL头文件和库文件.
--with-mmseg, 启用基于MMSeg的中文分词法，并指出在那里能找到MMSeg头文件和库文件.
--with-python, 启用Python数据源支持. 需要预先安装Python2.6.
3. 编译源代码生成二进制程序:
$ make
4. 安装二进制程序到你设定的目录下: (类Unix操作系统下默认为/usr/local/bin/ , 但是可以被 ./configure --prefix修改安装目录）
$ make install
二. 配置
[zdh@gy03 etc]# cat /usr/local/sphinx/etc/movie.conf
#
# Minimal Sphinx configuration sample (clean, simple, functional)
#
source movie
{
type = mysql
sql_host = dbIP
sql_user = dbuser
sql_pass = dbpassword
sql_db = dbname
sql_port = 3306 # optional, default is 3306
sql_query_pre = SET NAMES utf8
sql_query = \
SELECT index_id,movie_id, movie_name,movie_name_alias, movie_name_pinyin, starin,starin_pinyin, director, director_pinyin, movie_type, show_time, region,IFNULL(ABS(TO_DAYS(show_time)-TO_DAYS(now())),187375) as near, weight \
FROM index_movie
sql_attr_uint = movie_id
sql_attr_uint = near
sql_attr_uint = weight
#sql_attr_timestamp = show_time
#sql_attr_str2ordinal = movie_name
sql_query_info = SELECT movie_id, movie_name,starin, director, movie_type, show_time, region FROM index_movie WHEREindex_id=$id
}
index movie
{
source = movie
path =/usr/local/sphinx/var/data/movie
charset_type = utf-8
charset_table = 0..9, A..Z->a..z, _, a..z,U+410..U+42F->U+430..U+44F, U+430..U+44F
#morphology = none
chinese_dictionary =/usr/local/sphinx/etc/xdict
#min_stemming_len = 1
#ngram_len = 1
#min_word_len = 2
ngram_chars = U+3000..U+2FA1F
}
indexer
{
mem_limit = 32M
}
searchd
{
listen = 9312
#listen = 9306:mysql41
log =/usr/local/sphinx/var/log/searchd.log
query_log =/usr/local/sphinx/var/log/query.log
read_timeout = 5
max_children = 30
pid_file =/usr/local/sphinx/var/log/searchd.pid
max_matches = 1000
seamless_rotate = 1
preopen_indexes = 1
unlink_old = 1
workers = threads # for RT to work
binlog_path = /usr/local/sphinx/var/data
}
三. 启动和创建索引
[zdh@gy03 etc]# searchd -c etc/movie.conf #启动
[zdh@gy03 etc]# searchd -c etc/movie.conf--stop #关闭
在crontab里添加如下内容，使之定时更新
#sphinx indexer
00 06 * * * /usr/local/bin/indexer -c/usr/local/sphinx/etc/movie.conf movie --rotate
