MySQL-Python安装问题小记_MySQL

安装完mysql-python后import加载模块提示以下错误，

代码如下:

ImportError: libmysqlclient_r.so.16: cannot open shared object file: No such file or directory

于是google之，总结一下解决方法：

（1）在mysql-ython的安装目录下找到site.cfg，将

#mysql_config = XXXXXXXXXXXXXXXX

注释符号去掉，并填上mysql_config的地址

（2）将mysql/lib下所有关于libmysqlclient的so文件软链接到/usr/lib下。

ln -s /usr/local/mysql/lib/mysql/libmysqlclient* /usr/lib
ldconfig

这样在加载

import _mysql

的时候就不会出错了

ubuntu 安装mysql-python遇到的问题

版本是python 2.6

使用easy_install 安装MySQL-python

easy_install "MySQL-python==1.2.3"
提示：error: Setup script exited with error: command 'gcc' failed with exit status 1

需要安装 python-devel
sudo apt-get install python-dev
#apt-get install python-devel
再使用easy_install 安装就可以

如果使用python setup.py 安装，提示mysql_config找不到
EnvironmentError: mysql_config not found
需要安装下面2个开发包，需要注意的是apt-get里面是没有的，我使用新立德软件包管理器安装

libmysqld-dev
libmysqlclient-dev

安装完成以后需要修改MySQL-python-1.2.3文件夹下面的setup_posix.py中的第26行,

mysql_config.path = "mysql_config"改为mysql_config的路径

whereis mysql_config查找路径

mysql_config.path = "/usr/bin/mysql_config"

再使用
python setup.py build
python setup.py install
就可以

ubuntu root 权限
sudo -i

安装MySQL-python问题解决

今天在centos安装MySQL-python，结果报错，报错信息如下：

google找到答案（http://*.com/questions/13044201/install-mysql-python-return-error-in-centos），需要先安装mysql-devel.x86_64，通过

sudo yum install mysql-devel.x86_64

再次安装成功
