mysql打不开了怎么办

http://www.coreseek.cn/好像打不开了，但我们还在用coreseek的用户怎么办？

安装过程有一系列的问题，没有官网的支持 ，现总结下，方便大家查询。

# uname -r

3.10.0-229.4.2.el7.x86_64

安装步骤如下：

1 依赖包的安装

yum install gcc gcc-c++ libtool mysql-devel libxml2-devel expat-devel

2、下载软件包

wget http://www.coreseek.cn/uploads/csft/4.0/coreseek-4.1-beta.tar.gz

3、安装过程（不同版本安装过程基本相同，以3.2.4为例）

tar zxvfcoreseek-4.1-beta.tar.gz

cdcoreseek-4.1-beta

cd mmseg-3.2.14/

./bootstrap

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

make && make install

cd ../csft-4.1/

sh buildconf.sh

./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 --with-python

根据自己的环境需求，添加相关选项

make && make install

安装过程错误如下：

错误1

centOS7上安装4.1版本，执行 sh buildconf.sh 未生成configure

automake: warnings are treated as errors

/usr/share/automake-1.13/am/library.am: warning: ‘libstemmer.a‘: linking libraries using a non-POSIX

/usr/share/automake-1.13/am/library.am: archiver requires ‘AM_PROG_AR‘ in ‘configure.ac‘

libstemmer_c/Makefile.am:2: while processing library ‘libstemmer.a‘

/usr/share/automake-1.13/am/library.am: warning: ‘libsphinx.a‘: linking libraries using a non-POSIX

/usr/share/automake-1.13/am/library.am: archiver requires ‘AM_PROG_AR‘ in ‘configure.ac‘

src/Makefile.am:14: while processing library ‘libsphinx.a‘

总体意思是： archiver requires ‘AM_PROG_AR‘ in ‘configure.ac‘

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

这是由于缺少了python环境的devel支持包

解决办法：yum install python-devel

错误N:

/root/coreseek-4.1-beta/csft-4.1/src/sphinx.cpp:22292: undefined reference to `libiconv_open‘

/root/coreseek-4.1-beta/csft-4.1/src/sphinx.cpp:22310: undefined reference to `libiconv‘

/root/coreseek-4.1-beta/csft-4.1/src/sphinx.cpp:22316: undefined reference to `libiconv_close‘

collect2: ld returned 1 exit status

make[2]: *** [indexer] Error 1

make[2]: Leaving directory `/root/coreseek-4.1-beta/csft-4.1/src‘

make[1]: *** [all] Error 2

make[1]: Leaving directory `/root/coreseek-4.1-beta/csft-4.1/src‘

make: *** [all-recursive] Error 1

在其它机器上未发现此错误.

一开始以为libiconv的问题，又重装了几次还是一样，最后终于找着办法了

编辑：

./src/MakeFile文件

将

LIBS = -lm -lexpat -L/usr/local/lib

改成

LIBS = -lm -lexpat -liconv -L/usr/local/lib

就可以了。
