sphinx 全文搜索引擎：顾名思义，是做收索用的，因为普通的搜索在数据量小的时候，能应对自如，但是当数据量上千万，或者上亿的时候。纯粹的sql搜索显得缓慢，无力。因而为了提高用户体验，增快用户的搜索速度，出现了sphinx 。简单的例子比如大型网站的首页搜索。

1.安装须知

Coreseek发布了3.2.14版本和4.1版本等多个版本

3.2.14版本是2010年发布的，它是基于Sphinx0.9.9搜索引擎的。4.1版本是2011年发布的

，它是基于Sphinx2.0.2以后的

2.使用sphinx需要的工作

1.检查中文环境语言

2.升级依赖包

3.下载并安装mmseg(coreseek所需要的词典)

4.安装coreseek的csf-3.2-14(也就是sphinx)

5.安装配置sphinx并运行生成相应的索引

6.启动sphinx，php文件调用sphinx服务即可

7.配置php支持sphinx (或者引用sphinx类直接调用sphinx也行)

注意事项：①、采用API调用，如使用PHP、java等的API函数或方法查询。优点是可不必对mysql重新编译，服务端进程“低耦合”，且程序可灵活、方便的调用；需要二次查询。

二次查询注：到现在发布版本为止——sphinx-0.9.9，sphinx在检索到结果后只能返回记录的ID，而非要查的sql数据，故需要重新根据这些ID再次从数据库中查询，

3.检查环境语言

[root@localhost ~]# locale

LANG=en_US.UTF-8

LC_CTYPE="en_US.UTF-8"

LC_NUMERIC="en_US.UTF-8"

LC_TIME="en_US.UTF-8"

LC_COLLATE="en_US.UTF-8"

LC_MONETARY="en_US.UTF-8"

LC_MESSAGES="en_US.UTF-8"

LC_PAPER="en_US.UTF-8"

LC_NAME="en_US.UTF-8"

LC_ADDRESS="en_US.UTF-8"

LC_TELEPHONE="en_US.UTF-8"

LC_MEASUREMENT="en_US.UTF-8"

LC_IDENTIFICATION="en_US.UTF-8"

#如上显示英文的(如果是中文的直接进行下一步)

LANG=en_US.UTF-8

LC = en_US.UTF-8

#要配置成中文的

export LANG=zh_CN.UTF-8

export LC_ALL=zh_CN.UTF-8

#运行之后

[root@localhost ~]# export LANG=zh_CN.UTF-8

[root@localhost ~]# export LC_ALL=zh_CN.UTF-8

[root@localhost ~]# locale

LANG=zh_CN.UTF-8

LC_CTYPE="zh_CN.UTF-8"

LC_IDENTIFICATION="zh_CN.UTF-8"

LC_ALL=zh_CN.UTF-8

4升级依赖包

yum -y install glibc-common libtool autoconf automake mysql-devel expat-devel

# 手动升级 autoconf

tar -zxvf autoconf-2.69.tar.gz

cd autoconf-2.69

./configure

make

make install

5.安装coreseek的mmseg

tar -zxvf coreseek-3.2.13.tar.gz

cd coreseek-3.2.13

cd mmseg-3.2.13/

./bootstrap #输出的warning信息可以忽略，如果出现error则需要解决

./configure --prefix=/usr/local/mmseg3

make

make install

# 检测是否安装完成

mmseg

提示：-bash: mmseg: command not found

# 问题解决方法

ln -s /usr/local/mmseg3/bin/mmseg /bin/mmseg

#

mmseg

# 显示以下内容表示安装成功

Coreseek COS(tm) MM Segment 1.0

Copyright By Coreseek.com All Right Reserved.

Usage: mmseg

-u Unigram Dictionary

-r Combine with -u, used a plain text build Unigram Dictionary, default Off

-b Synonyms Dictionary

-t Thesaurus Dictionary

-h print this help and exit

安装csf-3.2-14

cd csft-3.2.13/

sh buildconf.sh #输出的warning信息可以忽略，如果出现error则需要解决

./configure \

--prefix=/usr/local/sphinx \

--without-unixodbc \

--with-mmseg \

--with-mmseg-includes=/usr/local/mmseg3/include/mmseg/ \

--with-mmseg-libs=/usr/local/mmseg3/lib/ \

--with-mysql=/usr/local/mysql/ \

make

make install

#./configure --prefix=/usr/local/sphinx/ --with-mysql=/usr/local/mysql/ --enable-id64

make

make install

# 注意1：采用这种方式安装不支持中文分词。

# 注意2：--enable-id64 系统是64位，开启后Sphinx存储模块可以支持4-5G,不开启支持2G左右，不开启检索效率会高些，一般情况下建议不开启

# 错误：

collect2: ld 返回 1

make[2]: *** [indexer] 错误 1

# 修改configure文件中：

LIBS="$LIBS -L/usr/local/lib"

# 改为：

LIBS="$LIBS -liconv -L/usr/local/lib"

6.再测试下mmseg分词和coreseek搜索

cd testpack

cat var/test/test.xml #此时应该正确显示中文

/usr/local/mmseg3/bin/mmseg -d /usr/local/mmseg3/etc var/test/test.xml

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

/usr/local/sphinx/bin/search -c etc/csft.conf 网络搜索

此时正确的应该返回

words:

1. '网络': 1 documents, 1 hits

2. '搜索': 2 documents, 5 hits

3.sphinx.conf配置文件

[root@localhost ~]#cd /usr/local/sphinx/etc #进入sphinx的配置文件目录

[root@localhost etc]# cp sphinx.conf.dist sphinx.conf #新建Sphinx配置文件

[root@localhost etc]# vim sphinx.conf #编辑sphinx.conf
