Ubuntu系统相较于windows系统来说，有许多功能与性能强大的地方。而且ubuntu系统是一个完全免费的操作系统，所以以后越来越多的用户会开始使用ubuntu系统。那下面学学ubuntu系统下Coreseek的安装配置吧。
一切按照官方的说明文档来安装，但到最好配置时却老配置老出错。最终只能再google一下，按下面的配置才算搞定。刚玩coreseek，对一些参数还不是很熟悉，但又想配置起来玩下，没有好好地看官方说明文档呵呵。
防止出现编译错误，先安装以下程序
yum -y install mysql mysql-devel php-mysql qt4-mysql python python-dev gcc-c++ gtk+ libtool automake autoconf glibc-common expat-devel
- 1.
1、安装
wget http://www.coreseek.cn/uploads/csft/3.1/Source/csft-3.1.tar.gz ####coreseek源文件
wget http://www.coreseek.cn/uploads/csft/3.1/Source/mmseg-3.1.tar.gz #####coreseek所使用的词典
tar zxvf csft-3.1.tar.gz
tar zxvf mmseg-3.1.tar.gz
#####在安装coreseek前必须先安装mmseg
cd mmseg-3.1
./configure –prefix=/usr/local/mmseg
make
make install
- 1.
- 2.
- 3.
- 4.
- 5.
- 6.
- 7.
######## 安装coreseek ########
##这里不使用python数据源，若需要，请加上 –with-python,在mmseg上一定要对应路径
./configure –prefix=/usr/local/coreseek –with-mmseg-includes=/usr/local/mmseg/include/mmseg –with-mmseg-libs=/usr/local/mmseg/lib –without-iconv
- 1.
指定–enable-id64选项会打开64位文档ID和词ID的支
make
make install
- 1.
- 2.
- 3.
若无问题，安装完毕后在/usr/local/下生成 coreseek目录及其下文件。
接下来要生成 mmseg词库及配置文件：
cd /usr/loca/mmseg
/usr/local/mmseg/bin/mmseg -u /usr/local/src/mmseg-3.1/data/unigram.txt ###unigram.txt是对应的词典文件，将会生成unigram.txt.uni
cd ../coreseek
mkdir dict ###创建字典目录
cp /usr/local/src/mmseg-3.1/data/unigram.txt.uni dict/uni.lib ###把创建的词典复制到dict
vim dict/mmseg.ini ####创建mmseg的配置文件，此文件在coreseek的windows版本已自带!
mmseg.ini:
[mmseg]
merge_number_and_ascii=1;
number_and_ascii_joint=-;
compress_space=0;
seperate_number_ascii=1;
- 1.
- 2.
- 3.
- 4.
- 5.
- 6.
- 7.
- 8.
- 9.
- 10.
- 11.
至此，mmseg配置完毕!下一步配置csft.conf——coreseek的配置文件

使用CLI端测试一下：
