sphinx安装

背景

博主近日开发个全文搜索功能，本能的就想到了sphinx搜索引擎。实现之

安装

yum install make gcc gcc++ gcc-c++ libtool autoconf automake imake mysql-devel libxml2-devel expat-devel
wget http://files.opstool.com/man/coreseek-4.1-beta.tar.gz
tar -xzvf coreseek-4.1-beta.tar.gz
cd coreseek-4.1-beta
cd mmseg-3.2.14
./bootstrap
./configure --prefix=/usr/local/mmseg3
make && make install
cd ..
cd csft-4.1
sh buildconf.sh

这个地方有可能生成不了configure文件，需要修改部分文件，具体内容参考http://blog.youkuaiyun.com/jcjc918/article/details/39032689）

## 错误1：

解决办法：在 csft-4.1/configure.ac 文件中，查找：
AC_PROG_RANLIB 
后面加上
AM_PROG_AR 
最终格式为：AC_PROG_RANLIB AM_PROG_AR
再次执行 sh buildconf.sh 

## 错误2：

'automake --add-missing' can install 'ar-lib'
在命令行执行
#automake --add-missing
再次执行 sh buildconf.sh

## 错误3

编译的时候出现
sphinxexpr.cpp:1823:43: error: ‘ExprEval’ was not declared in this scope, and no declarations were found by argument-dependent lookup at the point of instantiation [-fpermissive]
   T val = ExprEval ( this->m_pArg, tMatch ); // 'this' fixes gcc braindamage
处理办法：
 #vim /usr/local/src/coreseek-4.1-beta/csft-4.1/src/sphinxexpr.cpp
 1746                  T val = ExprEval ( this->m_pArg, tMatch );
 形式修改为  T val = this->ExprEval ( this->m_pArg, tMatch );
 1777                  T val = ExprEval ( this->m_pArg, tMatch );
 形式修改为  T val = this->ExprEval ( this->m_pArg, tMatch );
 1823                  T val = ExprEval ( this->m_pArg, tMatch );
 形式修改为  T val = this->ExprEval ( this->m_pArg, tMatch );

 错误4

 In file included from sphinxstd.cpp:24:0:
py_layer.h:16:27: fatal error: Python.h: No such file or directory
  #include   <Python.h>  
  这是由于缺少了python环境的devel支持包
  解决办法：yum install python-devel

./configure --prefix=/usr/local/coreseek --without-unixodbc --with-mmseg --with-mmseg-includes=/usr/local/mmseg3/include/mmseg/ --with-mmseg-libs=/usr/local/mmseg3/lib/ --with-mysql=/usr   （which mysql_config找到安装位置）
make && make install

建立索引命令
/usr/local/coreseek/bin/indexer -c /etc/sphinx.conf --all --rotate
启动命令
/usr/local/coreseek/bin/searchd -c /etc/sphinx.conf
搜索命令
/usr/local/coreseek/bin/search -c /etc/sphinx.conf 中国
停止命令
/usr/local/coreseek/bin/searchd -c /etc/sphinx.conf --stop

索引自动化建立

(项目下的crontab子目录已有,根据你实际情况修改)
建立shell脚本，主要用来执行sphinx建立索引，重启服务，同时会记录日志到该目录下的sphinx.log

cd crontab
vim indexer.sh:
killall -9 searchd 
/usr/local/coreseek/bin/indexer -c /etc/sphinx.conf --all --rotate && 
/usr/local/coreseek/bin/searchd -c /etc/sphinx.conf
time=`date "+%Y-%m-%d %H:%M:%S "`
echo "${time} sphinx restart success" >> /usr/share/nginx/html/blog/crontab/sphinx.log

然后定时任务中每3小时执行一次该脚本：

crontab -e
0 */3 * * * /usr/share/nginx/html/blog/crontab/indexer.sh
service crond restart
