使用sphinx索引mysql数据

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 = new SphinxClient;
     $s->setServer("localhost", 9312);
     $s->setMatchMode(SPH_MATCH_ANY);
     $s->setMaxQueryTime(3);
     $result = $s->query("stone");
     var_dump($result);
?>

运行php test.php

array(10) {
  ["error"]=>
  string(0) ""
  ["warning"]=>
  string(0) ""
  ["status"]=>
  int(0)
  ["fields"]=>
  array(1) {
    [0]=>
    string(4) "name"
  }
  ["attrs"]=>
  array(2) {
    ["name"]=>
    int(7)
    ["age"]=>
    int(1)
  }
  ["matches"]=>
  array(1) {
    [2]=>
    array(2) {
      ["weight"]=>
      int(1)
      ["attrs"]=>
      array(2) {
        ["name"]=>
        string(5) "stone"
        ["age"]=>
        int(6)
      }
    }
  }
  ["total"]=>
  int(1)
  ["total_found"]=>
  int(1)
  ["time"]=>
  float(0)
  ["words"]=>
  array(1) {
    ["stone"]=>
    array(2) {
      ["docs"]=>
      int(1)
      ["hits"]=>
      int(1)
    }
  }
}
