CentOS +Qt+mySQL

一、安装，启动mySQL:

1、CentOS中如果已经有了mySQL

      /etc/rc.d/init.d/./mysqld start   (启动mySQL, 此时可以运行mySQL -root)

      编辑rc.local文件  #vi /etc/rc.d/rc.local

      加入如下启动命令

      /etc/rc.d/init.d/mysqld start

      (mySQL 开机自动启动)

2、如果没有安装：

   1>、yum install mysql，

      安装后  需要重复 1 的步骤  设置开机自动重启；

   2>、 p { margin-bottom: 0.08in; }

     For CentOS 32-bit system: Get rpm

wget http://mysql.mirrors.pair.com/Downloads/MySQL-5.0/MySQL-server-community-5.0.92-1.rhel5.i386.rpm

wget http://mysql.mirrors.pair.com/Downloads/MySQL-5.0/MySQL-client-community-5.0.92-1.rhel5.i386.rpm

wget http://mysql.mirrors.pair.com/Downloads/MySQL-5.0/MySQL-devel-community-5.0.92-1.rhel5.i386.rpm

wget http://mysql.mirrors.pair.com/Downloads/MySQL-5.0/MySQL-shared-community-5.0.92-1.rhel5.i386.rpm

wget http://mysql.mirrors.pair.com/Downloads/MySQL-5.0/MySQL-shared-compat-5.0.92-1.rhel5.i386.rpm

p { margin-bottom: 0.08in; }

wget http://mysql.mirrors.pair.com/Downloads/MySQL-5.0/MySQL-server-community-5.0.92-1.rhel5.x86_64.rpm

    For CentOS 64-bit system: Get rpm

p { margin-bottom: 0.08in; }

wget http://mysql.mirrors.pair.com/Downloads/MySQL-5.0/MySQL-server-community-5.0.92-1.rhel5.x86_64.rpm

 

wget http://mysql.mirrors.pair.com/Downloads/MySQL-5.0/MySQL-client-community-5.0.92-1.rhel5.x86_64.rpm

wget http://mysql.mirrors.pair.com/Downloads/MySQL-5.0/MySQL-devel-community-5.0.92-1.rhel5.x86_64.rpm

wget http://mysql.mirrors.pair.com/Downloads/MySQL-5.0/MySQL-shared-community-5.0.92-1.rhel5.x86_64.rpm

wget http://mysql.mirrors.pair.com/Downloads/MySQL-5.0/MySQL-shared-compat-5.0.92-1.rhel5.x86_64.rpm

 

 

   Install

rpm -iUvh MySQL-server-community-5.0.92-1.rhel5.i386.rpm

rpm -iUvh MySQL-client-community-5.0.92-1.rhel5.i386.rpm

rpm -iUvh MySQL-devel-community-5.0.92-1.rhel5.i386.rpm

rpm -iUvh MySQL-shared-community-5.0.92-1.rhel5.i386.rpm

rpm -iUvh MySQL-shared-compat-5.0.92-1.rhel5.i386.rpm

 

rpm包安装会设置开机自动重启，不需要重复1的步骤。

 

二、编译安装mysql 使Qt能调用。   p { margin-bottom: 0.08in; }

export PATH=/opt/qtsdk-2010.04/qt/bin:$PATH

cd /opt/qtsdk-2010.04/qt/src/plugins/sqldrivers/mysql/

 

for 32-bit:

qmake -o Makefile 'INCLUDEPATH+=/usr/include/mysql' 'LIBS+=-L/usr/lib/mysql' mysql.pro

for 64-bit

qmake -o Makefile 'INCLUDEPATH+=/usr/include/mysql' 'LIBS+=-L/usr/lib64 /mysql' mysql.pro

make

cp libqsqlmysql.so ../../../../plugins/sqldrivers/

 

如果在qmake时候提示：qpluginbase.pri:10: Unknown replace function: qtLibraryTarget

则是因为export PATH=/opt/qtsdk-2010.04/qt/bin:$PATH  参数（path）错误

 

如果在make时候提示：../../../sql/drivers/mysql/qsql_mysql.h:52:19: error: mysql.h: No such file or directory

缺少mysql-devel

yum install mysql-devel

重新make

 

错误提示：

g++: /mysql: No such file or directory(是因为qmake那一步lib64后多了一个空格)
