sphinx 不关闭进程更新索引 和增量索引

更新单个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

上面呢是重头到尾的更新也就是每次从id1开始，所以会做重复工作，如果数据量小的话都可以接受，太大的话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时候记录下当前mysql表的最大id，然后主索引不动，定期去生成增量索引并更改最大id，然后将增量索引合并到主索引就行了

记录最大id表结构

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增量表最大记录数';

sphinx.conf配置

#定义主索引源

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) #记录最大记录数

    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
}

#增量索引数据源定义
source test_delta : test
{
        sql_query_pre = SET NAMES utf8
        sql_query_pre           = REPLACE INTO sph_counter (SELECT 1, MAX(id) FROM test) #记录最大记录数

        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 =                                #关闭binlog日志
}

生成主索引后定期更新增量合并索引，加入到crontab -e

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

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