篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了全文搜索引擎coreseek安装配置(sphinx)相关的知识,希望对你有一定的参考价值。
一、以下安装配置均经过实践检验,下文所有查询语句均为实际生成过程中的数据字段
1、特别说明安装次shpinx需要mysql环境 ,请先安装mysql5.6及以上版本
安装开始:
cd /data/softwore
wget http://www.coreseek.cn/uploads/csft/4.0/coreseek-4.1-beta.tar.gz(只安装中文分词mmseg3)
tar zxvf coreseek-4.1-beta.tar.gz
cdcoreseek-4.1-beta.tar.gz/
##安装mmseg $ cd mmseg-3.2.14 //根据具体的版本而定 $ ./bootstrap #输出的warning信息可以忽略,如果出现error则需要解决 $ ./configure --prefix=/usr/local/mmseg3 $ make && make install $ cd ..
5. 生成字典
因为用到中文分词,需要生成字典,去安装目录,比如我的是 /home/changyou/mmseg.3.0b3/data/
#mmseg -u unigram.txt 该命令执行后,将会产生一个名为unigram.txt.uni的文件,将该文件改名为uni.lib,完成词
-
-
- 遇到的问题:
- error: cannot find input file: src/Makefile.in
- 或者遇到其他类似error错误时...
- 解决方案:
- 依次执行下面的命令,我运行‘aclocal‘时又出现了错误,解决方案请看下文描述
- yum -y install libtool
- aclocal
- libtoolize --force
- automake --add-missing
- autoconf
- autoheader
- make clean
##安装sphinx
$ cd csft-4.1 $ sh buildconf.sh #输出的warning信息可以忽略,如果出现error则需要解决 $ ./configure --prefix=/usr/local/sphinx --without-unixodbc --with-mmseg --with-mmseg-includes=/usr/local/mmseg3/include/mmseg/ --with-mmseg-libs=/usr/local/mmseg3/lib/ --with-mysql-includes=/usr/local/webserver/mysql/include/mysql --with-mysql-libs=/usr/local/webserver/mysql/lib/mysql //此处的MySQL依赖库需要根据具体安装的MySQL路径有关/lib/mysql/为文件夹,有些系统没有mysql文件夹 直接指定到include或lib下即
##如果提示mysql问题,可以查看MySQL数据源安装说明 $ make && make install $ cd .. ##测试mmseg分词,coreseek搜索(需要预先设置好字符集为zh_CN.UTF-8,确保正确显示中文) $ cd testpack $ cat var/test/test.xml #此时应该正确显示中文 $ /usr/local/mmseg3/bin/mmseg -d /usr/local/mmseg3/etc var/test/test.xml
安装sphinx报错解决方法如下:
打开sphinx-2.1.9.release下的configure
##可能遇到的问题: ##如果提示libtool: unrecognized option `--tag=CC‘ ,请查看libtool问题解决方案 ##有的系统下可能出现:expected `;‘ before ‘CSphTokenizer_UTF8SpaceSeg’, ##或者出现:configure: WARNING: unrecognized options: --with-mmseg, --with-mmseg-includes, --with-mmseg-libs ##是因为你没有进行随后的sh buildconf.sh操作 ##生成当前系统对应的编译配置文件 ##需要使用以下指令: $ sh buildconf.sh ## Linux环境下,如遇到pthread问题,请先直接执行以下指令在进行configur: $ LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib $ export LD_LIBRARY_PATH ## 如果出现undefined reference to `libiconv‘的类似错误,可以按照如下方法处理: ##方法一:(Linux使用) ## 直接执行:export LIBS="-liconv" ##然后make clean,再次configure后,进行编译安装make && make install ## 方法二: ## 首先configure,然后vim src/makefile ## 在其中搜索lexpat,在其后加上 -liconv ## 修改后该行应该为:-lexpat -liconv -L/usr/local/lib ## 然后再次make && make install ## 方法三: ## 首先configure,然后vim config/config.h ## 在其中搜索USE_LIBICONV,将其后的1修改为0 ## 然后再次make && make install
下面开始sphinx与mysql的配置
创建sphinx统计表,在coreseek_test库中执行。
CREATE TABLE sph_counter
(
counter_id INTEGER PRIMARY KEY NOT NULL,
max_doc_id INTEGER NOT NULL
);
CREATE TABLE sph_counter1
(
counter_id INTEGER PRIMARY KEY NOT NULL,
max_doc_id INTEGER NOT NULL
)
配置数据源文件
vi /usr/local/sphinx/etc/sphinx.conf
source main
{
type = mysql
sql_host = localhost
sql_user = root
sql_pass = root
sql_db = db
{
type = mysql
sql_host = localhost
sql_user = root
sql_pass = root
sql_db = db
sql_port = 3306
sql_sock = /tmp/mysql.sock (不是必须)
sql_query_pre = SET NAMES utf8
sql_query_pre = REPLACE INTO sph_counter_product SELECT 1,MAX(id) from job
sql_query_pre = REPLACE INTO sph_counter_product SELECT 1,MAX(id) from job
#数据库中读取数据的sql
sql_query = SELECT id,name,companyname,radians(lat) as lat,radians(lng) as lng,salary,education,jobtype,secondtype,UNIX_TIMESTAMP(ctime) As ctime,UNIX_TIMESTAMP(mtime) As mtime from job where id<=(SELECT max_doc_id FROM sph_counter_product WHERE counter_id=1)
sql_query = SELECT id,name,companyname,radians(lat) as lat,radians(lng) as lng,salary,education,jobtype,secondtype,UNIX_TIMESTAMP(ctime) As ctime,UNIX_TIMESTAMP(mtime) As mtime from job where id<=(SELECT max_doc_id FROM sph_counter_product WHERE counter_id=1)
#支持全文索引
sql_field_string = name
#支持属性过滤
sql_attr_string = companyname
sql_attr_float = lat
sql_attr_float = lng
sql_attr_uint = salary
#sql_attr_uint = id
sql_attr_uint = education
sql_attr_uint = jobtype
sql_attr_uint = secondtype
sql_attr_timestamp = ctime
sql_attr_timestamp = mtime
sql_query_info_pre = SET NAMES utf8
sql_query_info = SELECT id,name,companyname,radians(lat) as lat,radians(lng) as lng,salary,education,jobtype,secondtype,UNIX_TIMESTAMP(ctime) As ctime,UNIX_TIMESTAMP(mtime) As mtime FROM job order by ctime desc
}
source delta : main
{
sql_query_pre = SET NAMES utf8
sql_query = SELECT id,name,companyname,radians(lat) as lat,radians(lng) as lng,salary,education,jobtype,secondtype,UNIX_TIMESTAMP(ctime) As ctime,UNIX_TIMESTAMP(mtime) As mtime FROM job WHERE id>(SELECT max_doc_id FROM sph_counter_product WHERE counter_id=1 )
sql_query_post_index = REPLACE INTO sph_counter_product SELECT 1,MAX(id) FROM job
}
#index 定义
index main
{
source = main
path = /usr/local/sphinx/var/data/mysql
docinfo = extern
mlock = 0
morphology = none
min_word_len = 1
html_strip = 0
charset_dictpath = /usr/local/mmseg3/etc/
charset_type = zh_cn.utf-8
}
index delta : main
{
source = delta
path = /usr/local/sphinx/var/data/delta
}
#全局index定义
indexer
{
mem_limit = 256M
}
searchd
{
listen = 9312
read_timeout = 5
max_children = 30
max_matches = 1000
seamless_rotate = 0
preopen_indexes = 0
#attr_flush_period= 300
#compat_sphinxql_magics = 0 (默认不监听)
unlink_old = 1pid_file = /usr/local/sphinx/var/log/searchd_mysql.pid #请修改为实际使用的绝对路径,例如:/usr/local/coreseek/var/...
log = /usr/local/sphinx/var/log/searchd_mysql.log #请修改为实际使用的绝对路径,例如:/usr/local/coreseek/var/...
query_log = /usr/local/sphinx/var/log/query_mysql.log
#请修改为实际使用的绝对路径,例如:/usr/local/coreseek/var/...
#binlog_path = #关闭binlog日志
}上面为数据源配置
调用命令列表:
启动后台服务(必须开启)
执行索引(查询、测试前必须执行一次)
/usr/local/sphinx/bin/indexer -c /usr/local/sphinx/etc/sphinx.conf --all --rotate
/usr/local/sphinx/bin/searchd -c /usr/local/sphinx/etc/sphinx.conf
启动报错 找不到mysql.sock 解决方法:
使用软链接 ln -s /tmp/mysql.sock /var/lib/mysql/mysql.sock
执行增量索引
/usr/local/sphinx/bin/indexer -c /usr/local/sphinx/etc/sphinx.conf delta --rotate
合并索引
/usr/local/sphinx/bin/indexer -c /usr/local/sphinx/etc/sphinx.conf --merge main delta --rotate --merge-dst-range deleted 0 0
(为了防止多个关键字指向同一个文档加上--merge-dst-range deleted 0 0)
后台服务测试
(为了防止多个关键字指向同一个文档加上--merge-dst-range deleted 0 0)
后台服务测试
# /usr/local/coreseek/bin/search -c /usr/local/coreseek/etc/csft_mysql.conf aaa
关闭后台服务
关闭后台服务
# /usr/local/sphinx/bin/searchd -c /usr/local/sphinx/etc/sphinx.conf --stop

自动化命令
crontab -e

以下任务计划的意思是:每隔一分钟执行一遍增量索引,每五分钟执行一遍合并索引,每天1:30执行整体索引。
分布式配置
- index dist
- {
- type = distributed
- agent = 127.0.0.1:9313:index_3307_0
- agent = 127.0.0.1:9313:index_3307_0_delta
- agent = 127.0.0.1:9314:index_3307_1
- agent = 127.0.0.1:9314:index_3307_1_delta
- agent = 127.0.0.1:9316:index_3308_0
- agent = 127.0.0.1:9316:index_3308_0_delta
- agent = 127.0.0.1:9317:index_3308_1
- agent = 127.0.0.1:9317:index_3308_1_delta
- agent = 127.0.0.1:9319:index_3309_0
- agent = 127.0.0.1:9319:index_3309_0_delta
- agent = 127.0.0.1:9320:index_3309_1
- agent = 127.0.0.1:9320:index_3309_1_delta
- agent_query_timeout = 100000
- }
- indexer
- {
- mem_limit = 1024M
- }
- searchd
- {
- listen = 9312
- read_timeout = 5
- max_children = 30
- max_matches = 6000
- seamless_rotate = 1
- preopen_indexes = 1
- unlink_old = 1
- compat_sphinxql_magics=0
- query_log_format = sphinxql
- pid_file = /usr/local/coreseek/var/log/searchd_mysql.pid
- log = /usr/local/coreseek/var/log/searchd_mysql.log
- query_log = /usr/local/coreseek/var/log/query_mysql.log
- #workers = threads
- dist_threads = 6 #几台分布式机器
- }
最后记得加入到开机命令中:
vi /etc/rc.local
