数据库表如下

mysql> select * from tb_account;

+----+-------+------+

| id | name | age |

+----+-------+------+

| 1 | ciaos | 3 |

| 2 | stone | 6 |

+----+-------+------+

安装sphinx

yum install sphinx libsphinxclient-devel

配置sphinx代替mysql全文索引(/etc/sphinx/sphinx.conf)(详细配置可参照 sphinx 配置文件全解析)

source account_src

{

type = mysql

sql_host = localhost

sql_user = root

sql_pass =

sql_db = test

sql_port = 3306

sql_query_pre = SET NAMES utf8

sql_query = \

SELECT * \

FROM tb_account

#sql_attr_uint = idx_id

sql_field_string = name

sql_attr_uint = age

}

index account_idx

{

source = account_src

path = /var/lib/sphinx/account_src

docinfo = extern

charset_type = utf-8

}

indexer

{

mem_limit = 32M

}

searchd

{

listen = 127.0.0.1:9312

listen = 9306:mysql41

log = /var/log/sphinx/searchd.log

query_log = /var/log/sphinx/query.log

read_timeout = 5

max_children = 30

pid_file = /var/run/sphinx/searchd.pid

max_matches = 1000

seamless_rotate = 1

preopen_indexes = 1

unlink_old = 1

workers = threads # for RT to work

binlog_path = /var/lib/sphinx

}

创建全量索引

indexer --config /etc/sphinx/sphinx.conf --all

启动后台搜索服务

searchd --config /etc/sphinx/sphinx.conf

可设置crontab定期构建索引

indexer --config /etc/sphinx/sphinx.conf --rotate account_idx

测试(自带search工具已不可用，可参照这里)，所以需要源码安装sphinx的php扩展

wget https://pecl.php.net/get/sphinx-1.3.3.tgz

phpize && ./configure && make &&make install<?php $s = newSphinxClient;$s->setServer("localhost", 9312);$s->setMatchMode(SPH_MATCH_ANY);$s->setMaxQueryTime(3);$result = $s->query("stone");var_dump($result);?>

运行php test.php
