sphinx3.1.1的安裝與使用

1. 下載sphinx3.1.1
   • wget http://sphinxsearch.com/files/sphinx-3.1.1-612d99f-linux-amd64.tar.gz
2. 解壓 
   • tar zxf sphinx-3.1.1-612d99f-linux-amd64.tar.gz
3. 改名 sphinx 並移動到 /usr/local/
   • mv sphinx-3.1.1 sphinx
   • mv sphinx /usr/local/
4. 到sphinx目錄下創建 data,log文件夾
   • cd /usr/local/sphinx
   • mkdir data && mkdir log
5. 在/usr/local/sphinx/etc 編寫 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/
  }

6. 在test數據庫中 運行/usr/local/sphinx/etc目錄下的example.sql文件
   • 進入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. 運行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
   • 復制/usr/local/sphinx/api/ 目錄下的 sphinxapi.php

1. • $sphinx = new SphinxClient();
     $q      = $_GET['key'] ?? 'test'; //搜索關鍵字
     // 3.1已經棄用了setMatchMode!直接寫查詢語法就可以
     // 如果要匹配字符串中任意一個詞或字使用如下寫法
     // '"string1" | "string2" | "string3"'
     
     // '@(title,content) string'  @括號中的是要搜索的字段 可以寫多個或單個
     
     // '^$string$'  表示全部匹配 類似mysql中的 fieldName = 'string'
     // 更多用法可以參考正則表達式或者官方文檔
     
     // 中文分詞擴展建議使用scws,官網安裝和使用教程說明很詳細,(不過sphinx自帶的一元分詞已經夠用了,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);

      運行結果如下:

結束,記得數據庫數據改變后需重新生成索引
