更新單個at_resource 索引 

/usr/local/sphinx211/bin/indexer -c /usr/local/sphinx211/etc/sphinx.conf   at_resource --rotate

更新全部索引

/usr/local/sphinx211/bin/indexer -c /usr/local/sphinx211/etc/sphinx.conf   --all --rotate

加上--rotate

上面呢是重頭到尾的更新也就是每次從id1開始，所以會做重複工作，如果資料量小的話都可以接受，太大的話就用下面增量索引吧

增量索引

主要思路就是你生成主索引的時候記錄下當前mysql表的最大id，然後主索引不動，定期去生成增量索引並更改最大id，然後將增量索引合併到主索引就行了

記錄最大id表結構

CREATE TABLE `sph_counter` (
  `id` int(11) unsigned NOT NULL,
  `max_id` int(11) unsigned NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='sphinx增量表最大記錄數';

sphinx.conf配置

#定義主索引源

source test
{
    type                    = mysql
    sql_host                = localhost
    sql_user                = root
    sql_pass                = 123456
    sql_db                    = test
    sql_port                = 3306
    sql_query_pre            = SET NAMES utf8
    sql_query_pre           = REPLACE INTO sph_counter (SELECT 1, MAX(id) FROM test) #記錄最大記錄數

    sql_query = select id from test where id<(select max_id from sph_counter where id=1)
    sql_query_info = select * from test where id = $id
}

#增量索引資料來源定義
source test_delta : test
{
        sql_query_pre = SET NAMES utf8
        sql_query_pre           = REPLACE INTO sph_counter (SELECT 1, MAX(id) FROM test) #記錄最大記錄數

        sql_query = select * from test  where id>=(select max_id from sph_counter where id=1)
        sql_query_info = select * from test where id = $id

    binlog_path =                                #關閉binlog日誌
}
 

生成主索引後定期更新增量合併索引，加入到crontab -e

增量索引
/usr/local/sphinx/bin/indexer -c /usr/local/sphinx/etc/sphinx.conf test_delta --rotate

合併索引
/usr/local/sphinx/bin/indexer -c /usr/local/sphinx/etc/sphinx.conf --merge test test_delta --rotate
