Sphinx是由俄羅斯人Andrew Aksyonoff開發的一個全文檢索索引引擎。意圖為其他應用提供高速、低空間佔用、高結果 相關度的全文檢索搜尋功能。Sphinx可以非常容易的與SQL資料庫和指令碼語言整合。當前系統內建MySQL和PostgreSQL 資料庫資料來源的支援,也支援從標準輸入讀取特定格式 的XML資料。
Sphinx的特性如下:
a) 高速的建立索引(在當代CPU上,峰值效能可達到10 MB/秒);
b) 高效能的搜尋(在2 – 4GB 的文本資料上,平均每次檢索回應時間小於0.1秒);
c) 可處理海量資料(目前已知可以處理超過100 GB的文本資料, 在單一CPU的系統上可處理100 M 文檔);
d) 提供了優秀的相關度演算法,基於短語相似性和統計(BM25)的複合Ranking方法;
e) 支援分布式搜尋;
f) 支援短語搜尋
g) 提供文檔摘要產生
h) 可作為MySQL的儲存引擎提供搜尋服務;
i) 支援布爾、短語、詞語相似性等多種檢索模式;
j) 文檔支援多個全文檢索索引欄位(最大不超過32個);
k) 文檔支援多個額外的屬性資訊(例如:分組資訊,時間戳記等);
l) 支援斷詞;
雖然mysql的MYISAM提供全文索引,但是效能卻不敢讓人恭維,另外資料庫畢竟不是很善於做這樣的事情,我們需要把這些活讓給更適合的程式去做,減少資料庫的壓力。因此採用Sphinx來做mysql的全文索引工具是一個很好的選擇。這個星期主要來學習這個這個工具的使用,下面將學習過程大致的記錄一下,做個備忘,也希望能對學習這個工具的其他朋友有所啟發。
安裝sphinx
wget http://sphinxsearch.com/files/sphinx-2.2.11-release.tar.gztar -xf sphinx-2.2.11-release.tar.gz && cd sphinx-2.2.11-release./configure --prefix=/usr/local/spinx --with-mysqlmake && make installln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib64/libsphinxclient 安裝(PHP模組需要)cd api/libsphinxclient./configure –prefix=/usr/local/sphinxmake && make install
2.安裝php擴充
wget http://pecl.php.net/get/sphinx-1.3.0.tgztar zxf sphinx-1.3.3.tgz && cd sphinx-1.3.3./configure --with-php-config=/usr/local/php/bin/php-config --with-sphinx=/usr/local/sphinx/make && make install
3.建立設定檔
cp /usr/local/sphinx/etc/sphinx-min.conf.dist /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 = www.123 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}index test1{ source = src1 path = /usr/local/spinx/var/data/test1}indexer{ mem_limit = 32M}searchd{ listen = 9312 listen = 9306:mysql41 log = /usr/local/spinx/var/log/searchd.log query_log = /usr/local/spinx/var/log/query.log read_timeout = 5 max_children = 30 pid_file = /usr/local/spinx/var/log/searchd.pid seamless_rotate = 1 preopen_indexes = 1 unlink_old = 1 workers = threads # for RT to work binlog_path = /usr/local/spinx/var/data}
4.建立索引並啟動
/usr/local/spinx/bin/indexer -c /usr/local/spinx/etc/sphinx.conf --all/usr/local/spinx/bin/searchd -c /usr/local/spinx/etc/sphinx.conf
5.查詢驗證
cd /root/sphinx-2.2.11-release/apipython test.py testDEPRECATED: Do not call this method or, even better, use SphinxQL instead of an APIQuery ‘test ‘ retrieved 3 of 3 matches in 0.000 secQuery stats: ‘test‘ found 5 times in 3 documentsMatches:1. doc_id=1, weight=2, group_id=1, date_added=2016-11-30 01:21:202. doc_id=2, weight=2, group_id=1, date_added=2016-11-30 01:21:203. doc_id=4, weight=1, group_id=2, date_added=2016-11-30 01:21:20
