sphinx3.1.1的安装与使用

下载sphinx3.1.1
- wget http://sphinxsearch.com/files/sphinx-3.1.1-612d99f-linux-amd64.tar.gz
解压
- tar zxf sphinx-3.1.1-612d99f-linux-amd64.tar.gz
改名 sphinx 并移动到 /usr/local/
- mv sphinx-3.1.1 sphinx
- mv sphinx /usr/local/
到sphinx目录下创建 data,log文件夹
- cd /usr/local/sphinx
- mkdir data && mkdir log

在/usr/local/sphinx/etc 编写 sphinx.conf 配置文件

vim /usr/local/sphinx/etc/sphinx.conf

#
# Minimal Sphinx configuration sample (clean, simple, functional)
#

source src1
{
    type                = mysql
    sql_host            = localhost
    sql_user            = root
    sql_pass            = root
    sql_db              = test
    sql_port            = 3306    # optional, default is 3306
    sql_query_pre       = SET NAMES utf8
    sql_query           = \
        SELECT id, group_id, UNIX_TIMESTAMP(date_added) AS date_added, title, content \
        FROM documents

    sql_attr_uint        = group_id
    sql_attr_timestamp   = date_added
}


index test1
{
    source                  = src1
    path                    = /usr/local/sphinx/data/test1
    min_word_len            = 1
    ngram_len               = 1
    ngram_chars             = U+3000..U+2FA1F
}

indexer
{
    mem_limit        = 128M
}

searchd
{
        listen                  = 9312
        listen                  = 9306:mysql41
        log                     = /usr/local/sphinx/log/searchd.log
        query_log               = /usr/local/sphinx/log/query.log
        read_timeout            = 5
        max_children            = 30
        pid_file                = /usr/local/sphinx/log/searchd.pid
        seamless_rotate         = 1
        preopen_indexes         = 1
        unlink_old              = 1
        binlog_path             = /usr/local/sphinx/data/
}

在test数据库中运行/usr/local/sphinx/etc目录下的example.sql文件
- 进入mysql
- use test;
- source /usr/local/sphinx/etc/example.sql
添加索引
- /usr/local/sphinx/bin/indexer -c /usr/local/sphinx/etc/sphinx.conf test1
- /usr/local/sphinx/bin/indexer -c /usr/local/sphinx/etc/sphinx.conf test1 --rotate // 重新生成索引命令
运行sphinx
- /usr/local/sphinx/bin/searchd -c /usr/local/sphinx/etc/sphinx.conf
- /usr/local/sphinx/bin/searchd -c /usr/local/sphinx/etc/sphinx.conf --stop //停止sphinx命令
php操作sphinx
- 复制/usr/local/sphinx/api/ 目录下的 sphinxapi.php

$sphinx = new SphinxClient();
$q      = $_GET['key'] ?? 'test'; //搜索关键字
// 3.1已经弃用了setMatchMode!直接写查询语法就可以
// 如果要匹配字符串中任意一个词或字使用如下写法
// '"string1" | "string2" | "string3"'

// '@(title,content) string'  @括号中的是要搜索的字段 可以写多个或单个

// '^$string$'  表示全部匹配 类似mysql中的 fieldName = 'string'
// 更多用法可以参考正则表达式或者官方文档

// 中文分词扩展建议使用scws,官网安装和使用教程说明很详细,(不过sphinx自带的一元分词已经够用了,一般不需要scws
//http://www.xunsearch.com/scws/

$sql    = "";
$host   = "127.0.0.1";
$port   = 9312;
$index  = "test1";
$sphinx->SetServer($host, $port);
$sphinx->SetConnectTimeout(10);
$sphinx->SetArrayResult(true);
$res = $sphinx->Query($q, $index);
print_r($res);

运行结果如下:

结束,记得数据库数据改变后需重新生成索引
