Centos环境下MySQL-python安装过程
1. 下载 MySQL-python-1.2.3.tar.gz
地址 https://sourceforge.net/projects/mysql-python/
2. 安装 MySQl-python
tar xvf MySQL-python-1.2.3.tar.gz
cd MySQL-python-1.2.3
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
运行上面的命令报错如下：
| [root@localhost MySQL-python-1.2.3]# python setup.py install Traceback (most recent call last): File "setup.py", line 5, in ? from setuptools import setup, Extension ImportError: No module named setuptools |
解决方法：
| wget http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz tar zxvf setuptools-0.6c11.tar.gz cd setuptools-0.6c11 python setup.py build python setup.py install |
_mysql.c:36:23: 错误：my_config.h：没有那个文件或目录
_mysql.c:38:19: 错误：mysql.h：没有那个文件或目录
_mysql.c:39:26: 错误：mysqld_error.h：没有那个文件或目录
_mysql.c:40:20: 错误：errmsg.h：没有那个文件或目录
设置include 头文件路径
export C_INCLUDE_PATH=/usr/local/mysql/include/mysql
继续安装：
| python setup.py build python setup.py install |
运行测试：
| [root@localhost MySQL-python-1.2.3]# python Python 2.4.3 (#1, Sep 3 2009, 15:37:37) [GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import MySQLdb /usr/lib64/python2.4/site-packages/MySQL_python-1.2.3-py2.4-linux-x86_64.egg/_mysql.py:3: UserWarning: Module _mysql was already imported from /usr/lib64/python2.4/site-packages/MySQL_python-1.2.3-py2.4-linux-x86_64.egg/_mysql.pyc, but /opt/python/MySQL-python-1.2.3 is being added to sys.path >>> |
报出一大堆警告信息，解决办法：删除MySQL-python源目录，再测试一下：
| [root@localhost python]# python Python 2.4.3 (#1, Sep 3 2009, 15:37:37) [GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import MySQLdb >>> |
Mysql模块终于正常了！
报错：
ImportError: libmysqlclient_r.so.16: cannot open shared object file: No such file or directory
1.确定libmysqlclient_r.so.16的位置
/usr/local/mysql/lib/mysql/libmysqlclient_r.so.16 -> libmysqlclient_r.so.16.0.0
2.确定libmysqlclient_r.so.16使用的函数库及其位置
ldd /usr/local/mysql/lib/mysql/libmysqlclient_r.so.16
/usr/local/mysql/lib/mysql/libmysqlclient_r.so.16.0.0
ldd -v /usr/local/mysql/lib/mysql/libmysqlclient_r.so.16
/lib64
3.拷贝函数库到需要位置
cp -af /usr/local/mysql/lib/mysql/libmysqlclient_r.so.16.0.0 /lib64 或者 vim /etc/ld.so.conf将/usr/local/mysql/lib/mysql该目录添加到第一行
4.ldconfig
5.ldconfig -v | grep libmysqlclient_r.so.16
import MySQLdb sucess!!!!
