最近因为有个工做任务须要搭个虚拟机环境，可是环境是搭建在内网，没法直接联网，不少软件都不能直接yum安装，html

安装过程实在十分不顺利，在此留个记录给有须要的朋友。python

环境是 CentOS 5.7 x64mysql

 

请选择合适的方式，下载python2.7.3安装包linux

http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2
 
安装前固然须要编译器gcc
 
  1. yum install gcc  
yum install gcc
为了安装setuptools，要须要安装zlib
 
  1. yum install zlib zlib-dev  
yum install zlib zlib-dev
解压安装python2.7
 
  1. tar jxvf Python-2.7.3.tar.bz2 
  2. cd Python-2.7.3 
  3. ./configure 
  4. make && make instal  
tar jxvf Python-2.7.3.tar.bz2
cd Python-2.7.3
./configure
make && make instal
这里请注意：
上面这一步是正常步骤，可是在centos5.7环境中，当你执行setuptools时可能会有如下报错：
 
  1. Traceback (most recent call last): 
  2.   File "<string>", line 1, in <module> 
  3. zipimport.ZipImportError: can't decompress data; zlib not available  
Traceback (most recent call last):
  File "<string>", line 1, in <module>
zipimport.ZipImportError: can't decompress data; zlib not available
 
解决方法是在上面的configure以后，编辑Modules/Setup文件
找到下面这句，去掉注释
 
  1. #zlib zlibmodule.c -I$(prefix)/include -L$(exec_prefix)/lib -lz   
#zlib zlibmodule.c -I$(prefix)/include -L$(exec_prefix)/lib -lz
从新编译安装：
 
  1. make & make install   
make & make install
 
把系统自带的2.4移除（依然会保留2.4版本：/usr/bin/python2.4）
 
  1. rm -f /usr/bin/python  
rm -f /usr/bin/python
把python执行软链接链接到2.7
 
  1. ln -s /usr/local/bin/python2.7 /usr/bin/python  
ln -s /usr/local/bin/python2.7 /usr/bin/python
编辑yum命令，把路径指明为2.4，由于yum必须基于2.4版本
 
  1. sed -ie 's#/usr/bin/python$#/usr/bin/python2.4#g' /usr/bin/yum   
sed -ie 's#/usr/bin/python$#/usr/bin/python2.4#g' /usr/bin/yum
 
对应python2.7.3版本的是
下载后，执行
 
  1. sh setuptools-0.6c11-py2.7.egg  
sh setuptools-0.6c11-py2.7.egg
 
出现如下信息表示成功
 
  1. Processing setuptools-0.6c11-py2.7.egg 
  2. Copying setuptools-0.6c11-py2.7.egg to /usr/local/lib/python2.7/site-packages 
  3. Adding setuptools 0.6c11 to easy-install.pth file 
  4. Installing easy_install script to /usr/local/bin 
  5. Installing easy_install-2.7 script to /usr/local/bin 
  6.

安装mysql相关包
 
  1. yum install MySQL-devel MySQL-client MySQL-shared-compat MySQL-shared  
yum install MySQL-devel MySQL-client MySQL-shared-compat MySQL-shared
下载好mysqldb
 
 
  1. tar xvzf MySQL-python-1.2.3.tar.gz 
  2. cd MySQL-python-1.2.3 
  3. vim site.cfg 
  4. 把上面的mysql_config路径注释删除以及改为实际路径，若是不知道mysql_config在哪里，运行命令：whereis mysql_config 
  5. python setup.py install  
tar xvzf MySQL-python-1.2.3.tar.gz
cd MySQL-python-1.2.3
vim site.cfg
把上面的mysql_config路径注释删除以及改为实际路径，若是不知道mysql_config在哪里，运行命令：whereis mysql_config
python setup.py install
 
安装mysqldb总是报错：

  2. running build_py 
  3. copying MySQLdb/release.py -> build/lib.linux-x86_64-2.7/MySQLdb

说找不到 mysqlclient ，真心不可能，我把mysql-devel 、 mysql-client、mysql-shared都装上了。
 
只好从系统查找该文件，再创建软链接
 
  1. find / -name 'libmysqlclient.so.*' 
  2. /usr/lib64/libmysqlclient.so.14 
  3. /usr/lib64/libmysqlclient.so.12 
  4. /usr/lib64/libmysqlclient.so.14.0.0 
  5. /usr/lib64/libmysqlclient.so.12.0.0 
  6. /usr/lib64/libmysqlclient.so.16 
  7. /usr/lib64/libmysqlclient.so.15 
  8. /usr/lib64/libmysqlclient.so.15.0.0 
  9. /usr/lib64/libmysqlclient.so.16.0.0  
find / -name 'libmysqlclient.so.*'
/usr/lib64/libmysqlclient.so.14
/usr/lib64/libmysqlclient.so.12
/usr/lib64/libmysqlclient.so.14.0.0
/usr/lib64/libmysqlclient.so.12.0.0
/usr/lib64/libmysqlclient.so.16
/usr/lib64/libmysqlclient.so.15
/usr/lib64/libmysqlclient.so.15.0.0
/usr/lib64/libmysqlclient.so.16.0.0
创建软链接
 
  1. ln -s /usr/lib64/libmysqlclient.so.16.0.0 /usr/lib/libmysqlclient.so  
ln -s /usr/lib64/libmysqlclient.so.16.0.0 /usr/lib/libmysqlclient.so
 
再次install
 
  1. python setup.py install  
python setup.py install
 
若是这个步骤没有报错，表示基本完成
进入python命令行模式
 
  1. python  
python
再import MySQLdb，注意大小写呢
 
  1. Python 2.7.3 (default, Dec 10 2012, 14:33:49) 
  2. [GCC 4.1.2 20080704 (Red Hat 4.1.2-51)] on linux2 
  3. Type "help", "copyright", "credits" or "license" for more information. 
  4. >>> import MySQLdb 
  5. /usr/local/lib/python2.7/site-packages/MySQL_python-1.2.3-py2.7-linux-x86_64.egg/_mysql.py:3: UserWarning: Module _mysql was already imported from /usr/local/lib/python2.7/site-packages/MySQL_python-1.2.3-py2.7-linux-x86_64.egg/_mysql.pyc, but /home/soft/MySQL-python-1.2.3 is being added to sys.path
