• 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
    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 
    4. Installing easy_install script to /usr/local/bin 
    5. Installing easy_install-2.7 script to /usr/local/bin 
    6.  
    7. Installed /usr/local/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg

    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：

    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
