本文实例讲述了php启用sphinx全文搜索的实现方法。分享给大家供大家参考。具体分析如下：

在编译安装 sphinx 的时候出现很多中文乱码,最后抛出错误卡住了,我去到官方直接下载一个 rpm 包,安装就很爽,具体错误不想研究了,忙开发呢.

安装两个包,一个是 mmseg 这个是生成中文字典的程序,一个是 csft 也就是中国版的sphinx .

rpm -ivh 安装完以后,很顺利~~不到半分钟就装完了.

中文字典库,我直接去 csft 官方下载了,挺好的想得很周到.

unigram.txt uni.lib

unigram.txt 字典文本,可以在里面添加你自己的关键字.

然后使用:mmseg -u unigram.txt 生成字典文件:unigram.txt.uni 然后重命名一下 uni.lib 这个就是sphinx 认识的字典了.

放哪里？放你在 sphinx.conf 里面配置的字典路径里面,等会说到,然后基本就差不多了,在看下sphinx 几个实用的程序:

[root@beihai365 /]# csft-

csft-indexer csft-search csft-searchd

csft-indexer 是生成全文搜索索引的 程序

csft-search 是测试搜索是否生效用的，也很好用，不如我还没用客户端脚本开发，就可以用这个来查看全文搜索是否成功

csft-searchd 这个就是 sphinx 搜索的守护程序了。 启动以后，就可以用脚本 php python 等，开查询了。

就那么简单,在看下关键的两部分东西.

sphinx.conf 配置文件:

1. source tmsgs
2. {
3. type = mysql
4. sql_host = localhost
5. sql_user = root
6. sql_pass = 1
7. sql_db = phpwind75sp3
8. sql_port = 3306 # optional, default is 3306
9. #sql_sock = /tmp/mysql3307.sock
10. sql_query_pre = SET NAMES gbk
11. sql_query = SELECT id,name,type,stock FROM pw_tools
12. #sql_attr_uint = id
13. sql_attr_uint = stock
14. }
15. index tmsgsindex
16. {
17. source = tmsgs
18. path = /var/mmseg/searchdata/beihai365
19. docinfo = extern
20. charset_type = zh_cn.gbk
21. #min_prefix_len = 0
22. #min_infix_len = 2
23. #ngram_len = 2
24. charset_dictpath = /var/mmseg/data
25. #min_prefix_len = 0
26. #min_infix_len = 0
27. #min_word_len = 2
28. }
29. indexer
30. {
31. mem_limit = 128M
32. }
33. searchd
34. {
35. #listen = 3312
36. log = /var/log/searchd.log
37. query_log = /var/log/query.log
38. read_timeout = 5
39. max_children = 30
40. pid_file = /var/log/searchd.pid
41. max_matches = 1000
42. #seamless_rotate = 1
43. #preopen_indexes = 0
44. #unlink_old = 1
45. }
46. source tmsgs
47. {
48. type = mysql
49. sql_host = localhost
50. sql_user = root
51. sql_pass = 1
52. sql_db = phpwind75sp3
53. sql_port = 3306 # optional, default is 3306
54. #sql_sock = /tmp/mysql3307.sock
55. sql_query_pre = SET NAMES gbk
56. sql_query = SELECT id,name,type,stock FROM pw_tools
57. #sql_attr_uint = id
58. sql_attr_uint = stock
59. }
60. index tmsgsindex
61. {
62. source = tmsgs
63. path = /var/mmseg/searchdata/beihai365
64. docinfo = extern
65. charset_type = zh_cn.gbk
66. #min_prefix_len = 0
67. #min_infix_len = 2
68. #ngram_len = 2
69. charset_dictpath = /var/mmseg/data
70. #min_prefix_len = 0
71. #min_infix_len = 0
72. #min_word_len = 2
73. }
74. indexer
75. {
76. mem_limit = 128M
77. }
78. searchd
79. {
80. #listen = 3312
81. log = /var/log/searchd.log
82. query_log = /var/log/query.log
83. read_timeout = 5
84. max_children = 30
85. pid_file = /var/log/searchd.pid
86. max_matches = 1000
87. #seamless_rotate = 1
88. #preopen_indexes = 0
89. #unlink_old = 1
90. }

再看一下,测试客户端代码:

1. <?php
2. header("Content-type:text/html;charset=utf-8");
3. include 'sphinxapi.php';
4. $cl = new SphinxClient();
5. $cl->SetServer('localhost',3312);
6. $cl->SetMatchMode(SPH_MATCH_ALL);
7. $cl->SetArrayResult(true);
8. $res = $cl->Query("名卡","*");
9. print_r($res);
10. ?>
11. <?php
12. header("Content-type:text/html;charset=utf-8");
13. include 'sphinxapi.php';
14. $cl = new SphinxClient();
15. $cl->SetServer('localhost',3312);
16. $cl->SetMatchMode(SPH_MATCH_ALL);
17. $cl->SetArrayResult(true);
18. $res = $cl->Query("名卡","*");
19. print_r($res);
20. ?>

“名卡”这个关键字是我自己手动在字典里面添加的,看是否能真的搜到,实例代码如下:

1. Array
2. (
3. [error] =>
4. [warning] =>
5. [status] => 0
6. [fields] => Array
7. (
8. [0] => name
9. [1] => type
10. )
11. [attrs] => Array
12. (
13. [stock] => 1
14. )
15. [matches] => Array
16. (
17. [0] => Array
18. (
19. [id] => 8
20. [weight] => 1
21. [attrs] => Array
22. (
23. [stock] => 100
24. )
25. )
26. )
27. [total] => 1
28. [total_found] => 1
29. [time] => 0.018
30. [words] => Array
31. (
32. [名卡] => Array
33. (
34. [docs] => 1
35. [hits] => 1
36. )
37. )
38. )
39. Array
40. (
41. [error] =>
42. [warning] =>
43. [status] => 0
44. [fields] => Array
45. (
46. [0] => name
47. [1] => type
48. )
49. [attrs] => Array
50. (
51. [stock] => 1
52. )
53. [matches] => Array
54. (
55. [0] => Array
56. (
57. [id] => 8
58. [weight] => 1
59. [attrs] => Array
60. (
61. [stock] => 100
62. )
63. )
64. )
65. [total] => 1
66. [total_found] => 1
67. [time] => 0.018
68. [words] => Array
69. (
70. [名卡] => Array
71. (
72. [docs] => 1
73. [hits] => 1
74. )
75. )
76. )

完全没问题,搜索出来了,几个关键的操作:

[root@beihai365 /]# csft-searchd --stop 停止搜索守护

[root@beihai365 /]# csft-indexer --all 针对所有节点生成索引,你也可以针对某个节点生成索引比如:csft-indexer xx

[root@beihai365 /]# csft-search App 搜索关键字 App,不过看下面信息没有搜到和没有命中任何的文档.

1. Coreseek Full Text Server 3.1
2. Copyright (c) 2006-2008 coreseek.com
3. using config file './csft.conf'...
4. 1,
5. pt:1, 1; index 'tmsgsindex': query 'App ': returned 0 matches of 0 total in 0.017 sec
6. words:
7. 1. 'app': 0 documents, 0 hits

当大家在运行这些命令的时候发现,需要你自己手动的置顶 --config sphinx.conf 配置文件的路径,很不方便,所以我干脆 ln -s 一个在 ./,这样不用每次都去敲入 --config.

希望本文所述对大家的php程序设计有所帮助。
