1. 准备工作

下载源码包

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

查看是否安装make工具

~#rpm -qa|grep makeautomake-1.11.1-4.el6.noarchmake-3.81-20.el6.x86_64

如果没有安装make工具

yum -y install gcc automake autoconf libtool make

查看是否安装zlib库

~#rpm -qa|grep zlibzlib-devel-1.2.3-29.el6.x86_64zlib-1.2.3-29.el6.x86_64

安装zlib

yum install zlib-devel

检查是否安装ssl 库

~#rpm -qa|grep opensslopenssl-devel-1.0.1e-16.el6_5.x86_64openssl-static-1.0.1e-16.el6_5.x86_64openssl098e-0.9.8e-17.el6.centos.2.x86_64openssl-1.0.1e-16.el6_5.x86_64openssl-perl-1.0.1e-16.el6_5.x86_64

安装openssl

yum install openssl*

安装bzip2依赖库

yum install -y bzip2*

2. 编译安装

cp Python-2.7.3.tar.bz2 /usr/src/tar -jxvf Python-2.7.3.tar.bz2vi Modules/Setup.dist

找到

#SSL=/usr/local/ssl#_ssl _ssl.c \# -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \# -L$(SSL)/lib -lssl -lcrypto......#zlib zlibmodule.c -I$(prefix)/include -L$(exec_prefix)/lib -lz

把注释去掉

编译

./configure --prefix=/usr/local/python2.7make all make installmake cleanmake distclean

安装成功

~#/usr/local/python2.7/bin/python2.7Python 2.7.3 (default, Dec 18 2013, 15:43:35) [GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2Type "help", "copyright", "credits" or "license" for more information.>>> cd /usr/local/python2.7python setup.py install

建立python2.7 软链

~#mv /usr/bin/python /usr/bin/python.bak~#ln -s /usr/local/python2.7/bin/python2.7 /usr/bin/python2.7~#ln -s /usr/bin/python2.7 /usr/bin/python

3. 解决yum无法使用的问题

~#yum updateThere was a problem importing one of the Python modulesrequired to run yum. The error leading to this problem was: No module named yumPlease install a package which provides this module, orverify that the module is installed correctly.It's possible that the above module doesn't match thecurrent version of Python, which is:2.7.3 (default, Dec 18 2013, 15:43:35) [GCC 4.4.7 20120313 (Red Hat 4.4.7-4)]If you cannot solve this problem yourself, please go to the yum faq at: http://yum.baseurl.org/wiki/Faq

因为centos 6.4 下yum默认使用的是python2.6

vi /usr/bin/yum----------------------------------------------------#!/usr/bin/pythonimport systry: import yumexcept ImportError:.......

修改为

#!/usr/bin/python2.6........

4. 安装python-pip工具

先安装setup-tools

wget https://pypi.python.org/packages/2.7/s/setuptools/setuptools-0.6c11-py2.7.egg --no-check-certificatechmod +x setuptools-0.6c11-py2.7.eggsh setuptools-0.6c11-py2.7.egg

安装pip

wget https://pypi.python.org/packages/source/p/pip/pip-1.3.1.tar.gz --no-check-certificatecp pip-1.3.1.tar.gz /usr/src/tar zxvf pip-1.3.1.tar.gzcd pip-1.3.1python setup.py installln -s /usr/local/python2.7/bin/pip /usr/bin/pip
