[root@zhu2 MySQL-python-1.2.3]# python setup.py build
Traceback (most recent call last):

from setuptools import setup, Extension
ImportError: No module named setuptools
#这是由于python里缺少setuptools这个模块引起的。
#解决方法如下

下载setuptools软件安装
wget https://pypi.python.org/packages/source/s/setuptools/setuptools-3.3.tar.gz#md5=87680a0eb0bb6f720d5e2d89ba67debc --no-check-certificate
1.python连接mysql需要的模块MySQLdb默认是没有安装的,所以需要单独的安装后才能使用,安装的方法有编译安装和yum安装。虽是个小模块,但安装时也遇到了一些问题。
编译安装:
1.下载所需软件
#可在此地址下找到需要的版本。
wget
#解压
tar xf MySQL-python-1.2.3.tar.gz
2.安装
[root@jiang MySQL-python-1.2.3]# python setup.py build
Traceback (most recent call last):
File "setup.py", line 5, in <module>
from setuptools import setup, Extension
ImportError: No module named setuptools
#这个报错是由于缺少setuptools这个模块引起的,解决方法如下:
wget https://pypi.python.org/packages/source/s/setuptools/setuptools-3.3.tar.gz#md5=87680a0eb0bb6f720d5e2d89ba67debc
tar xf setuptools-3.3.tar.gz
python setup.py build
python setup.py install
继续安装
unable to execute gcc: No such file or directory
error: command 'gcc' failed with exit status 1
#出现这个错误时,解决方法如下:
yum -y install python-devel mysql-devel gcc
解决该错误后继续安装
[root@jiang MySQL-python-1.2.3]# python setup.py build
[root@jiang MySQL-python-1.2.3]# python setup.py install
这样便可成功安装

>>> import MySQLdb
假如mysql使用的是编译安装,那么也可能碰到问题
mysql_config not found #找不到mysql的安装路径
vim setup_posix.py #找到第26行左右
mysql_config.path = "mysql_config" #修改为对应的mysql安装路径即可,比如
/opt/mysql/bin/mysql_config
#######################
/usr/bin/ld: cannot find -lmysqlclient_r #这个错误是找不到mysql的库文件
解决方法:
echo "/usr/local/mysql/lib/mysql" >> /etc/ld.so.conf
ldconfig
如果没有libmysqlclient_r.so 就建立一个软连接 ln -s libmysqlclient.so libmysqlclient_r.so

yum安装更为便捷可选
yum -y install MySQL-python #使用yum安装便不会出现那么多的包依赖问题了。
