coreseek sphinx 创建表和索引的语句

2017年10月16日 PHP技术文章暂无评论阅读 0 views 次

下面来看一个coreseek sphinx 创建表和索引的语句例子,希望此文章能帮助到各位理解coreseek sphinx数据库.

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,代码如下:

[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.

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,代码如下:

# 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,代码如下:

# 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,代码如下:

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,代码如下:

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,代码如下:

# 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,代码如下:

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)
