Sphinx-for-chinese (中文全文搜索)安装步骤

前提，你的机器上已经安装过mysql数据库。如果没有安装，则运行以下命令安装

sudo apt-get install mysql-client-5.0 mysql-server-5.0

1. 下载所需的安装包
     sphinx-for-chinese-0.9.9-r2117.tar.gz
    xdict_1.1.tar.gz
    下载地址： http://co de.google.com/p/sphinx-for-chinese/downloads/list

2. 解压 tar -zxvf sphinx-for-chinese-0.9.9-r2117.tar.gz

3. 编译安装
$ cd sphinx-for-chinese-0.9.9-r2117.tar.gz
$ ./configure
$ make
$ sudo make install

4. 创建test数据库,并创建sphinx用户
mysql> create database test;
mysql> create user 'sphinx'@'localhost' identified by 'sphinx';
mysql> grant all privileges on test.* to 'sphinx'@'localhost';

5. 指定sphinx配置文件
$ cd /usr/local/etc
$ cp sphinx.conf.dist sphinx.conf

6. 编辑该配置文件
vi sphinx.conf
改动内容如下：
sql_host        = localhost
sql_user        = sphinx
sql_pass        = sphinx
sql_db          = test
sql_port        = 3306  # optional, default is 3306
说明：加粗部分是修改的内容

到这里为止，sphinx已经可以使用了，但还不能支持中文切词,以下是加入中文切词的步骤
1. 解压字典文件 xdict_1.1.tar.gz

$ tar zxvf xdict_1.1.tar.gz

2. 借助先前安装的 mkdict 工具生成字典

$ /usr/local/sphinx/bin/mkdict xdict.txt xdict

3. 将字典 xdict 拷贝到 /usr/local/sphinx/etc目录下

4. 配置中文切词
打开 sphinx.conf文件，找到 ‘charset_type    = sbcs’ 字样，将其改为:

charset_type    = utf-8
chinese_dictionary = /usr/local/sphinx/etc/xdict

至此中文切词配置完成，下面做一个简单的测试
1. 编辑sphinx-for-chinese自带的SQL脚本，加入中文数据
$ vi /usr/local/sphinx/etc/example.sql

REPLACE INTO test.documents ( id, group_id, group_id2, date_added, title, content ) VALUES( 1, 1, 5, NOW(), 'test one', 'this is my test document number one. also checking search within phrases.' ),( 2, 1, 6, NOW(), 'test two', 'this is my test document number two' ),( 3, 2, 7, NOW(), 'another doc', 'this is another group' ),( 4, 2, 8, NOW(), 'doc number four', 'this is to test groups' ),( 5, 2, 8, NOW(), 'doc number five', '一个' ),( 6, 2, 8, NOW(), 'doc number six', '我' ),( 7, 2, 8, NOW(), 'doc number seven', '中国人' );

说明：加粗部分是添加的中文测试数据

2. 导入数据

$ mysql -usphinx -psphinx < example.sql

3. 建立索引

$ sudo /usr/local/sphinx/bin/indexer --all

如果出以下错误：就给他建 一个

FATAL: failed to open /var/data/test1.spl: No such file or directory, will not index. Try --rotate option.

Thats not trying to read that file, but rather create it.
Does /var/data/ folder exist, and is it writable?

mkdir data

4. 检索
$ /usr/local/sphinx/bin/search 我是一个中国人

至此，Sphinx-for-chinese已经成功安装，并通过测试。
