sphinx3.1.1的安装与使用

1. 下载sphinx3.1.1
   • wget http://sphinxsearch.com/files/sphinx-3.1.1-612d99f-linux-amd64.tar.gz
2. 解压 
   • tar zxf sphinx-3.1.1-612d99f-linux-amd64.tar.gz
3. 改名 sphinx 并移动到 /usr/local/
   • mv sphinx-3.1.1 sphinx
   • mv sphinx /usr/local/
4. 到sphinx目录下创建 data,log文件夹
   • cd /usr/local/sphinx
   • mkdir data && mkdir log
5. 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            =     # optional, default is
      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            =
      ngram_len               =
      ngram_chars             = U+..U+2FA1F
  }
  
  indexer
  {
      mem_limit        = 128M
  }
  
  searchd
  {
          listen                  =
          listen                  = :mysql41
          log                     = /usr/local/sphinx/log/searchd.log
          query_log               = /usr/local/sphinx/log/query.log
          read_timeout            =
          max_children            =
          pid_file                = /usr/local/sphinx/log/searchd.pid
          seamless_rotate         =
          preopen_indexes         =
          unlink_old              =
          binlog_path             = /usr/local/sphinx/data/
  }

6. 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
7. 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
8. 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

9. php操作sphinx
   • 复制/usr/local/sphinx/api/ 目录下的 sphinxapi.php

1. • $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
