python下的MysqlDB包的安装详解

首先，请安装mysql

sudo apt-get install mysql

期间，需要设置root 密码

下载mysql-python: http://sourceforge.net/projects/mysql-python/?source=dlp

解压： tar  zxvf  MySQL-python-1.2.4b4.tar.gz

进到该目录： cd MySQL-python-1.2.4b4

执行安装脚本：  python setup.py build 

                              python setup.py install  

这个时候就会出现问题了：

sh: mysql_config: command not found Traceback (most recent call last): File "setup.py", line 15, in <module> metadata, options = get_config() File "/usr/lib/python2.5/MySQL-python-1.2.3/setup_posix.py", line 43, in get_config libs = mysql_config("libs_r") File "/usr/lib/python2.5/MySQL-python-1.2.3/setup_posix.py", line 24, in mysql_config raise EnvironmentError("%s not found" % (mysql_config.path,)) EnvironmentError: mysql_config not found

根据提示可知，mysql_config 找不到！！！！

网友解决思路如下：

vi site.cfg 
把 mysql_config = /usr/local/mysql/bin/mysql_config 这一行前的#去掉，并且把mysql_config的路径设置正确。 
python setup.py build 
sudo python setup.py install 

但是我的系统中根本就找不到mysql_config 文件，原因是该文件是通过安装另外一个包才能安装到系统中的

另一位牛人回复到：

mysql-config is in a different package, which can be installed from (again, assuming debian / ubuntu):

sudo apt-get install libmysqlclient-dev

好了，终于找到原因了，于是安装包libmysqlclient-dev

然后查看mysql_config 文件的安装目录是/usr/bin/mysql_config

于是可以按照以下几种方案解决：

1， 创建链接 sudo ln -s /usr/local/mysql/bin/mysql_config   /usr/bin/mysql_config   （前者是你的site.cfg中的mysql_config文件路径，后者是实际路径）

2， add /usr/local/mysql/bin/ to your path

3， 修改 site.cfg 文件： mysql_config = /usr/bin/mysql_config，记得要将这条语句之前的#去掉

OK，问题基本解决，此时执行一下 python setup.py build 和 sudo python setup.py install, 结果如下：
