Centos 5.x 升级 python2.7，安装setuptools、mysqldb 完整记录

 

最近由于有个工作任务需要搭个虚拟机环境，但是环境是搭建在内网，无法直接联网，很多软件都不能直接yum安装，

安装过程实在十分不顺利，在此留个记录给有需要的朋友。

环境是 CentOS 5.7 x64

请选择合适的方式，下载python2.7.3安装包

http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2

 

安装前当然需要编译器gcc

1. yum install gcc

yum install gcc

为了安装setuptools，要需要安装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，但是在centos5.7环境中，当你执行setuptools时可能会有以下报错：

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之后，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 

重新编译安装：

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执行软连接连接到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，因为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

http://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11-py2.7.egg

下载后，执行

1. sh setuptools-0.6c11-py2.7.egg

sh setuptools-0.6c11-py2.7.egg

 

出现以下信息表示成功

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

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成实际路径，如果不知道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成实际路径，如果不知道mysql_config在哪里，运行命令：whereis mysql_config
python setup.py install

 

安装mysqldb老是报错：

4. running build_ext

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，再建立软连接

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

建立软连接

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

 

如果这个步骤没有报错，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

完成！
