Sphinx安装与基本设置Sphinx是什么?如果你还不知道,那就放狗吧…简单引用一下官方wiki的文章:Sphinx是一个基于SQL的全文检索引擎,可以结合MySQL,PostgreSQL做全文搜索,它可以提供比数据库本身更专业的搜索功能,使得应用程序更容易实现专业化的全文检索。Sphinx特别为一些脚本语言设计搜索API接口,如PHP,Python,Perl,Ruby等,同时为MySQL也设计了一个存储引擎插件。Sphinx的特性:高速索引 (在新款CPU上,近10 MB/秒);高速搜索 (2-4G的文本量中平均查询速度不到0.1秒);高可用性 (单CPU上最大可支持100 GB的文本,100M文档);提供良好的相关性排名支持分布式搜索;提供文档摘要生成;提供从MySQL内部的插件式存储引擎上搜索支持布尔,短语, 和近义词查询;支持每个文档多个全文检索域(默认最大32个);支持每个文档多属性;支持断词;支持单字节编码与UTF-8编码;先下载最新稳定版的源代码:http://www.sphinxsearch.com/downloads/sphinx-0.9.8.tar.gz参照官方文档,貌似这个东西最好和mysql5.1级别的mysql进行搭配,没办法,再去下载一个mysql5.1.x的源代码吧:http://dev.mysql.com假设下载的源代码都保存在/tmp,先安装支持sphinx引擎的mysql:12tar xvf mysql-5.1.26-rc.tar.gztar xvf sphinx-0.9.8.tar.gz拷贝sphinx的mysql引擎到mysql源代码:1cp -R ./sphinx-0.9.8/mysqlse ./mysql-5.1.26/storage/sphinx重建mysql的configure文件12cd mysql-5.1.26-rcsh BUILD/autorun.sh编译过程需要加一条sphinx的参数,其他参数就与平时编译mysql一样。比如我的:123./configure --prefix=/usr/local/mysql --with-extra-charsets=all --with-big-tables --with-plugins=sphinxmakemake installmysql编译的其他细节就不再多写了…安装过了以后进入mysql命令行,运行show engines,看是不是有一个叫sphinx的engine,有的话就表示sphinxSE(mysql的sphinx引擎)安装正常了 。然后编译Sphinx,进入sphinx源代码目录:12345ldconfig /usr/local/mysql/lib/mysqlldconfig /usr/local/mysql/include/mysql./configure --prefix=/usr/local/sphinx --with-mysql=/usr/local/mysqlmakemake install到现在为止,兵器我们已经造好,下面就是怎么运用了~时间问题,一下子也没有仔细研究,就拿PHPWind当了试验品了。PW的主题表数据结构为:1234567891011121314151617181920212223242526272829303132333435363738394041CREATE TABLE IF NOT EXISTS `pw_threads` (`tid`

ENGINE=MyISAM实际使用的时候,我们要对主题表的标题“subject”,所在版块”fid”,发帖时间”postdate”进行全文检索,然后根据主键”tid”以及浏览量”hits”来进行排序,下面就用sphinx来实现这个需求。先配置Sphinx:sphinx是以sphinx.conf为配置文件,索引与搜索均以这个文件为依据进行,要进行全文检索,首先就要配置好sphinx.conf,告诉sphinx哪些字段需要进行索引,哪些字段需要在where,orderby,groupby中用到。12cd /usr/local/sphinx/etcvi sphinx.conf.dist打开sphinx.conf.dist以后可以发现他的配置文件是这种格式:1234567891011121314151617181920source 源名称1{…}index 索引名称1{source=源名称1…}source 源名称2{…}index 索引名称2{source =

前两天安装好了Sphinx,并简单索引了一个phpwind的主题表来做测试。今天有时间稍微研究了一下phpwind的数据表,大致做了一个适 合于phpwind的Sphinx配置文件。
sphinx.zip (1.8 KiB, 563 hits)
看了看phpwind的搜索程序search.php,发现他的搜索在“搜索帖子范围”这一项里面分了三种:
主题标题主题标题与主题内容回复标题与回复内容再看看phpwind的数据表,按照phpwind的搜索,我们必须在sphinx中为pw_threads,pw_tmsgs,pw_posts三个表 分别建立索引。由于我没有大数据量phpwind论坛数据,也就没有办法做那种实际的压力与速度测试,只是在命令行下进行了一些简单的测试,应该说这样配 置Sphinx应该没有问题了。
时间问题,只能研究到这里了,下面一个项目如果真的用到phpwind,再继续用sphinx这把刀把phpwind好好宰割一下。
