what is Sphinx

Sphinx 是一个可全文搜索的开源搜索引擎。最大的特点是可以有效地执行大数据的搜索。要索引的数据可以来自完全不同的源：SQL 数据库，纯文本文件，HTML 文件，邮箱等。

environment

Ubuntu 14.04

install

sudo apt-get install sphinxsearch -y
# sudo aptitude install sphinx3 sphinx3-doc sphinxsearch sphinx-common -y

configuring Sphinx

sudo vim /etc/sphinxsearch/sphinx.conf

Sphinx 配置包含 3 个必须运行的主要块。它们是 index searchd source

source

The source block contains the type of source, username and password to the MySQL server. The first column of the SQL query should be a unique id. The SQL query will run on every index and dump the data to Sphinx index file. Below are descriptions of each field and the source block itself.

sql_query: This is the query thats dumps data to index.

source src1
{
  type          = mysql
  sql_host      = localhost
  sql_user      = root
  sql_pass      = password
  sql_db        = test
  sql_port      = 3306 # optional, default is 3306

  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

  sql_query_info        = SELECT * FROM documents WHERE id=$id
}

index

The index component contains the source and the path to store the data.

source: Name of the source block. In our example, this is src1.
path: This path to save the index.
charset_type: This is the charset of the index.

index test1
{
  source            = src1
  path          = /var/lib/sphinxsearch/data/test1
  docinfo           = extern
  charset_type      = utf-8
}

searchd

The searchd component contains the port and other variables to run the Sphinx daemon.

listen: This is the port which sphinx daemon will run. In our example, this is 9312.
query_log: This path to save the query log.
pid_file: This is path to PID file of Sphinx daemon.
max_matches: Maximum number matches to return per search term.
seamless_rotate: Prevents searchd stalls while rotating indexes with huge amounts of data to precache.
preopen_indexes: Whether to forcibly preopen all indexes on startup.
unlink_old: Whether to unlink old index copies on successful rotation.

searchd
{
  listen            = 9312   # Port to listen on
  log           = /var/log/sphinxsearch/searchd.log
  query_log     = /var/log/sphinxsearch/query.log
  read_timeout      = 5
  max_children      = 30
  pid_file      = /var/run/sphinxsearch/searchd.pid
  max_matches       = 1000
  seamless_rotate       = 1
  preopen_indexes       = 1
  unlink_old        = 1
  binlog_path       = /var/lib/sphinxsearch/data
}

adding data to the index

sudo indexer -c /etc/sphinxsearch/sphinx.conf test1
# sudo indexer --all

为了使索引保持最新，创建 cronjob

crontab -e

@hourly /usr/bin/indexer --rotate --config /etc/sphinxsearch/sphinx.conf --all

starting Sphinx

sudo searchd -c /etc/sphinxsearch/sphinx.conf

other way

默认情况下，Sphinx 守护程序已关闭。要启用 Sphinx，首先打开 /etc/default/sphinxsearch

sudo vim /etc/default/sphinxsearch

Find the line START=no and set it to yes.

START=yes

Finally, start the Sphinx daemon.

sudo service sphinxsearch start

但是我遇到：

Job for sphinxsearch.service failed because the control process exited with error code. See "systemctl status sphinxsearch.service" and "journalctl -xe" for details

stop

sudo searchd --stop

testing search

sudo search -c /etc/sphinxsearch/sphinx.conf google

using Sphinx by PHP

install PHP extension

个人不推荐，下面有更新内容

安装 PHP Sphinx 依赖库

sudo apt-get install libsphinxclient-dev  libsphinxclient-0.0.1 -y

安装 PHP Sphinx 扩展

sudo pecl install sphinx

在配置文件 php.ini 中添加 Sphinx 的扩展

sudo vim /etc/php5/fpm/php.ini

extension=sphinx.so

重启 php5-fpm

sudo /etc/init.d/php5-fpm restart

call in PHP

个人不推荐，下面有更新内容

public function testSphinx()
{
	$s = new \SphinxClient;
	$s->setServer("localhost", 9312);
	$s->SetArrayResult (true);
	$s->setMatchMode(SPH_MATCH_ANY);
	$s->setMaxQueryTime(3);
	$result = $s->query("test");
	$result = $result['matches'];
	$result = array_column($result,'id');
	dump($result);
}

using nilportugues/sphinx-search

2017 年 07 月 19 日更新：

我在 Ubuntu 16.04 环境下，发现 libsphinxclient-dev libsphinxclient-0.0.1 无法正常安装，所以查找其他方法。

Installing Sphinx PHP API on Ubuntu 16.04 | Sphinx 中提到了 sphinxapi.php，联想到最近使用的 Composer，找到了 nilportugues/sphinx-search - Packagist SphinxClient 这个类中有很多 set 方法，我想这就和上面的 PHP 扩展的内容差不多，省去了安装扩展库。

$ composer require nilportugues/sphinx-search

<?php

$sphinxSearch = new \NilPortugues\Sphinx\SphinxClient();

//Do connection and set up search method...
$sphinxSearch->setServer('127.0.0.1',9312);


// Do search...
// Result would contain "The Amazing Spider-Man 2", to be in theatres in 2014.
$sphinxSearch->setFilter('year',array(2014));
$result = $sphinxSearch->query('Spiderman','movies');

// Unset the filter to stop filtering by year
// Now we'll get all the Spiderman movies.
$sphinxSearch->removeFilter('year');
$result = $sphinxSearch->query('Spiderman','movies');
