coreseek sphinx 创建表和索引
前面说了，coreseek sphinx mmseg mysql等的安装，下面说一下怎么使用。
一,coreseek sphinx启动后，会多出一个端口，并且可以像mysql一样登录，但不是登录mysql
[root@localhost tank]# mysql -h 127.0.0.1 -P 9306 //不是真的连接mysql，而连接了sphinx index Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 1 Server version: 1.11-id64-dev (r2540) Copyright (c) 2000, 2013, Oracle and/or its affiliates. All rights reserved.

Type '\c' to clear the current input statement. mysql> select * from tank_test where match('坦克') ; //这种写法，根原装的sphinx不一样 +------+--------+------------+------+ | id | weight | user_id | u_id | +------+--------+------------+------+ | 3 | 2230 | 1311895260 | 62 | | 5 | 2230 | 1311895260 | 33 | | 4 | 1304 | 1311895262 | 0 | | 6 | 1304 | 1311895262 | 34 | +------+--------+------------+------+ 4 rows in set (0.00 sec) mysql> show META; //上次检索的信息 +---------------+-------+ | Variable_name | Value | +---------------+-------+ | total | 3 | | total_found | 3 | | time | 0.000 | | keyword[0] | test | | docs[0] | 3 | | hits[0] | 5 | +---------------+-------+ 6 rows in set (0.00 sec) mysql> show tables; //这里的表其实不是真表，也不是create table创建出来的，是sphinx索引 +--------------+-------------+ | Index | Type | +--------------+-------------+ | dist1 | distributed | | myorder | local | | rt | rt | | tank_test | rt | | test1 | local | | test1stemmed | local | +--------------+-------------+ 6 rows in set (0.00 sec)
二，创建sphinx索引
1,修改/usr/local/sphinx/etc/sphinx.conf
# vim /usr/local/sphinx/etc/sphinx.conf //添加以下内容 index tank_test { type = rt path = /usr/local/sphinx/var/data/rt charset_dictpath = /usr/local/mmseg3/etc/ charset_type = zh_cn.utf-8 ngram_len = 0 rt_field = name rt_field = title rt_field = sub_title rt_attr_uint = user_id rt_attr_uint = uid }
在这里要注意，rt_field是检索字段，rt_attr_uint是返回字段
2,重启sphinx
# pkill -9 searchd # /usr/local/sphinx/bin/indexer --config /usr/local/sphinx/etc/sphinx.conf --all # /usr/local/sphinx/bin/searchd --config /usr/local/sphinx/etc/sphinx.conf
3，插入数据，并查看
mysql> show tables; +--------------+-------------+ | Index | Type | +--------------+-------------+ | dist1 | distributed | | rt | rt | | tank_test | rt | //新增加的索引 | test1 | local | | test1stemmed | local | +--------------+-------------+ 5 rows in set (0.00 sec) mysql> desc tank_test; +-----------+---------+ | Field | Type | +-----------+---------+ | id | bigint | | name | field | | title | field | | sub_title | field | | user_id | integer | | u_id | integer | +-----------+---------+ 6 rows in set (0.00 sec) mysql> insert into tank_test values (3,'坦克','tank is 坦克','技术总监',1311895260,33); mysql> insert into tank_test values (4,'tank张','tank is 坦克','技术总监',1311895262,34); mysql> select * from tank_test where match('坦克'); //匹配搜索的字段是rt_field +------+--------+------------+------+ | id | weight | user_id | u_id | //返回的字段是rt_attr_uint +------+--------+------------+------+ | 3 | 2230 | 1311895260 | 33 | | 4 | 1304 | 1311895262 | 34 | +------+--------+------------+------+ 2 rows in set (0.00 sec)
id和weight是系统自带的返回字段
到这儿索引就创建好了，show tables的时候是可以看新建的tank_test，用phpmyadmin或者其他mysql数据库连接工具根本看不到，原因是他根本不是真实的表。sphinx到底能不能用真实的表呢？
三，创建表，并添加索引
1,创建真实的表,插入数据
CREATE TABLE IF NOT EXISTS `orders` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`user_id` int(11) NOT NULL ,
`username` varchar(20) NOT NULL,
`create_time` datetime NOT NULL,
`product_name` varchar(20) NOT NULL,
`summary` text NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;
INSERT INTO `orders` (`user_id` ,`username` ,`create_time` ,`product_name` ,`summary`) VALUES
('1311895262','张三','2014-08-01 00:24:54','tank is 坦克','技术总监'),
('1311895263','tank张二','2014-08-01 00:24:54','tank is 坦克','技术经理'),
('1311895264','tank张一','2014-08-01 00:24:54','tank is 坦克','DNB经理'),
('1311895265','tank张','2014-08-01 00:24:54','tank is 坦克','运维总监');
在这里要注意，是连接mysql的3306端口，不是连接coreseek sphinx的9306
2，修改/usr/local/sphinx/etc/sphinx.conf，添加以下内容
source order
{
type = mysql
sql_host = localhost
sql_user = root
sql_pass =
sql_db = test
sql_query_pre = SET NAMES utf8
sql_query = \
SELECT id, user_id, username, UNIX_TIMESTAMP(create_time) AS create_time, product_name, summary \
FROM orders
sql_attr_uint = user_id
sql_attr_timestamp = create_time
sql_ranged_throttle = 0
sql_query_info = SELECT * FROM orders WHERE id=$id
}
index myorder
{
source = order
path = /usr/local/sphinx/var/data/myorder
docinfo = extern
mlock = 0
morphology = none
min_word_len = 1
charset_dictpath = /usr/local/mmseg3/etc/
charset_type = zh_cn.utf-8
ngram_len = 0
html_strip = 0
}
3,重启sphinx
# pkill -9 searchd # /usr/local/sphinx/bin/indexer --config /usr/local/sphinx/etc/sphinx.conf --all # /usr/local/sphinx/bin/searchd --config /usr/local/sphinx/etc/sphinx.conf
4，切换到9306，检索测试
mysql> show tables;
+--------------+-------------+
| Index | Type |
+--------------+-------------+
| dist1 | distributed |
| myorder | local |
| rt | rt |
| tank_test | rt |
| test1 | local |
| test1stemmed | local |
+--------------+-------------+
6 rows in set (0.00 sec)
mysql> desc myorder;
+--------------+-----------+
| Field | Type |
+--------------+-----------+
| id | bigint |
| username | field |
| product_name | field |
| summary | field |
| user_id | integer |
| create_time | timestamp |
+--------------+-----------+
6 rows in set (0.00 sec)
mysql> select * from myorder where match('坦克');
+------+--------+------------+-------------+
| id | weight | user_id | create_time |
+------+--------+------------+-------------+
| 5 | 1304 | 1311895262 | 1407081600 |
| 6 | 1304 | 1311895263 | 1406823894 |
| 7 | 1304 | 1311895264 | 1406823894 |
| 8 | 1304 | 1311895265 | 1406823894 |
+------+--------+------------+-------------+
4 rows in set (0.00 sec)
