    随着自己电影网站资源逐渐增多,增加电影资源搜索服务成为必然。直接操作数据库的搜索,IO口请求增多减低了搜索性能。之前项目中有sphinx的使用基础,加之支持中文检索服务,最后决定采用基于sphinx的Coreseek搜索服务。

    下载安装步骤【本人采用 linux环境下 4.1版本,系统支持mysql和xml数据源】:

  1.  coreseek下载地址,下载 coreseek-4.1-beta.tar.gz 包

  2.   解压gz包,tar zxvf coreseek-4.1-beta.tar.gz

  3.  编译安装 mmseg【中文分词包】

    1. ./bootstrap

    2. ./configure --prefix=/usr/local/mmseg3 

    3. make && make install

  4.  编译安装 coreseek 

    1. sh buildconf.sh  #输出的warning信息可以忽略,如果出现error则需要解决 

    2. ./configure --prefix=/usr/local/coreseek  --without-unixodbc --with-mmseg --with-mmseg-includes=/usr/local/mmseg3/include/mmseg/ --with-mmseg-libs=/usr/local/mmseg3/lib/ --with-mysql  #with-mmseg-libs就是mmseg中文分词路径

    3. make && make install

    电影网站更新周期比较长,sphinx采用主索引+增量索引方式进行索引,最后合并两个索引文件。下面开始部署自己的搜索配置文件:

  1. 进入coreseek安装目录下的etc文件,新建或修改 .conf配置文件

  2. 配置source源 

    1. source movie
      {
          type              = mysql
          sql_host        = localhost #mysql数据库host
          sql_user        = root    #mysql用户
          sql_pass        =           #mysql用户密码
          sql_db          = movie  #movie
          sql_port        = 3306   # optional, default is 3306
          sql_query_pre            = SET NAMES utf8
        
          #建立增量索引 
          sql_query_pre = REPLACE INTO movie_sph_counter SELECT 1, MAX(id) FROM movie
          sql_query = SELECT id, UNIX_TIMESTAMP(cdate) AS date ,id AS movie_id ,name, year, type,status,sync_status FROM movie WHERE id

         #搜索返回字段
          sql_attr_uint   = movie_id
          sql_attr_uint   = year
          sql_attr_uint   = type
          sql_attr_uint   = date
          sql_attr_uint   = status
          sql_attr_uint   = sync_status                   
          sql_field_string = name

          sql_query_info_pre      = SET NAMES utf8                                        #命令行查询时,设置正确的字符集
          sql_query_info            = SELECT * FROM movie WHERE id=$id #命令行查询时,从数据库读取原始数据信息
      }

      #增量索引源
      source delta : movie
      {
          sql_query_pre = SET NAMES utf8
          sql_query = SELECT id, UNIX_TIMESTAMP(cdate) AS date ,id AS movie_id ,name , year, type ,status,sync_status FROM movie WHERE id>( SELECT max_movie_id FROM movie_sph_counter WHERE counter_id=1 )
          sql_query_post_index =  REPLACE INTO movie_sph_counter SELECT 1, MAX(id) FROM movie
      }

  3. 配置索引

    1. #index定义
      index movie
      {
          source            = movie            #对应的source名称
          path              = /usr/local/coreseek/var/data/movie #请修改为实际使用的绝对路径,例如:/usr/local/coreseek/var/...
          docinfo            = extern
          mlock            = 0
          morphology        = none
          min_word_len        = 1
          html_strip                = 0

          #中文分词配置,详情请查看:http://www.coreseek.cn/products-install/coreseek_mmseg/
          charset_dictpath = /usr/local/mmseg/etc/ #BSD、Linux环境下设置,/符号结尾  mmseg路径
        
          charset_type        = zh_cn.utf-8  #中文编码
      }

      index delta : movie
      {
          source = delta
          path            = /usr/local/coreseek/var/data/movie_delta   #注意!!不要和主索引路径名称一样

          docinfo         = extern
          mlock           = 0
          morphology      = none
          min_word_len    = 1
          html_strip      = 0

          charset_dictpath = /usr/local/mmseg/etc/
          charset_type     = zh_cn.utf-8
      }

  4.  配置搜索服务 

    1. #searchd服务定义
      searchd
      {
          listen                  =   9312  #端口号,可以自己定义
          read_timeout        = 5
          max_children        = 30
          max_matches            = 1000
          seamless_rotate        = 0
          preopen_indexes        = 0
          unlink_old            = 1
          
          compat_sphinxql_magics=0
          pid_file = /usr/local/coreseek/var/log/searchd_mysql.pid  #请修改为实际使用的绝对路径,例如:/usr/local/coreseek/var/...
          log = /usr/local/coreseek/var/log/searchd_mysql.log        #请修改为实际使用的绝对路径,例如:/usr/local/coreseek/var/...
          query_log = /usr/local/coreseek/var/log/query_mysql.log #请修改为实际使用的绝对路径,例如:/usr/local/coreseek/var/...
          binlog_path =                                #关闭binlog日志
      }

  5. 执行命令建立索引:  /usr/local/coreseek/bin/indexer -c movie.conf --all

  6. 后台开启搜索服务运行:/usr/local/coreseek/bin/searchd  -c movie.conf

  7. 建立定时任务,执行增量索引:/usr/local/coreseek/bin/indexer -c csft_movie.conf delta --rotate

  8. 建立定时任务,合并索引:/usr/local/coreseek/bin/indexer -c csft_movie.conf --merge movie delta --merge-dst-range deleted 0 0 --rotate

  9. 至此基于sphinx+mysql的搜索服务已经搭建完毕,接下来就是根据sphinxapi.php开发搜索接口代码……

    第一次自己搭建sphinx搜索服务,最后测试网站搜索,速度杠杠的。

    特此分享,希望对大家有所帮助
