首先建立一個計數表，保存數據表的最新記錄ID
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';
#定義主索引源
source test
{
type = mysql
sql_host = localhost
sql_user = root
sql_pass = 8888
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 where status=1 #取最大記錄數
sql_query = select id from test where id<(select max_id from sph_counter where id=1) and status = 1
##如果這裡不加id<的條件，合並索引時會報字段數不匹配的錯誤
#FATAL: failed to merge index 'test_delta' into index 'test': fulltext fields count mismatch (me=/usr/local/sphinx/var/data/test, in=/usr/local/sphinx/var/data/test_delta, myfields=4, infields=5)
sql_query_info = select * from test where id = $id
}
#增量索引數據源定義
source test_delta : test
{
sql_query_pre = SET NAMES utf8
sql_query = select * from test where id>=(select max_id from sph_counter where id=1) and status = 1
sql_query_info = select * from test where id = $id
}
#定義主索引
index test
{
source = test #對應的source名稱
path = /usr/local/sphinx/var/data/test #請修改為實際使用的絕對路徑，例如：/usr/local/coreseek/var/...
docinfo = extern
mlock = 0
morphology = none
min_word_len = 2
html_strip = 1
#中文分詞配置，詳情請查看：http://www.coreseek.cn/products-install/coreseek_mmseg/
charset_dictpath = /usr/local/mmseg/etc/ #BSD、Linux環境下設置，/符號結尾

charset_type = zh_cn.utf-8
}
#定義增量索引
index test_delta:test
{
source = test_delta #對應的source名稱
path = /usr/local/sphinx/var/data/test_delta #請修改為實際使用的絕對路徑，例如：/usr/local/coreseek/var/...

}
#全局index定義
indexer
{
mem_limit = 128M
}
#searchd服務定義
searchd
{
listen = 9312
read_timeout = 5
max_children = 30
max_matches = 1000
seamless_rotate = 0
preopen_indexes = 0
unlink_old = 1
pid_file = /usr/local/sphinx/var/log/searchd_mysql.pid #請修改為實際使用的絕對路徑，例如：/usr/local/coreseek/var/...
log = /usr/local/sphinx/var/log/searchd_mysql.log #請修改為實際使用的絕對路徑，例如：/usr/local/coreseek/var/...
query_log = /usr/local/sphinx/var/log/query_mysql.log #請修改為實際使用的絕對路徑，例如：/usr/local/coreseek/var/...
binlog_path = #關閉binlog日志
}
保存配置文件後退出，先停止searchd進程再啟動，然後重新生成索引。
停止進程
/usr/local/sphinx/bin/searchd -c /usr/local/sphinx/etc/csft.conf --stop
啟動進程
/usr/local/sphinx/bin/searchd -c /usr/local/sphinx/etc/csft.conf
重新生成所有索引
/usr/local/sphinx/bin/indexer -c /usr/local/sphinx/etc/csft.conf --all --rotate
增量索引
/usr/local/sphinx/bin/indexer -c /usr/local/sphinx/etc/csft.conf test_delta --rotate
合並索引
/usr/local/sphinx/bin/indexer -c /usr/local/sphinx/etc/csft.conf --merge test test_delta --rotate
如果合並索引時出現下面問題：
FATAL: failed to merge index 'test_delta' into index 'test': source index preload failed: failed to open /usr/local/sphinx/var/data/test_delta.sph: No such file or directory
停止searchd進程，然後重新啟動searchd進程。
增量索引可以放在crontab裡根據需要設置幾分鐘運行一次，然後執行索引合並，至於主索引重建可以選擇在訪問量不大或者半夜運行。
##每5分鐘運行增量索引
*/5 * * * /usr/local/sphinx/bin/indexer -c /usr/local/sphinx/etc/csft.conf test_delta --rotate > /dev/null 2>&1
##每10分鐘執行一次增量索引合並
*/10 * * * /usr/local/sphinx/bin/indexer -c /usr/local/sphinx/etc/csft.conf --merge test test_delta --rotate
##凌晨0點5分重新建立主索引
5 0 * * * /usr/local/sphinx/bin/indexer -c /usr/local/sphinx/etc/csft.conf --all --rotate > /dev/null 2>&1
