Linux下Python环境搭建

系统环境
 
OS:Oracle Linux Enterprise 5.6
 
 
1.下载
 
Python
 
地址: http://www.python.org/getit/
 
版本: Python-2.7.3.tgz
 
 
 
setuptools
 
地址:http://pypi.python.org/pypi/setuptools#downloads
 
版本:setuptools-0.6c11.tar.gz(md5)
 
也可以采用wget方式下载:
 
wget http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz#md5=7df2a529a074f613b509fb44feefe74e
 
 
 
2.安装Python
 
–查看系统自带的python:
 
[root@njdyw ~]# python
 
python      python2      python2.4
 
 
 
–安装Python2.7.3
 
[root@njdyw ~]# mkdir /python
 
[root@njdyw ~]# cp Python-2.7.3.tgz /python/
 
[root@njdyw ~]# cd /python/
 
[root@njdyw python]# ls
 
Python-2.7.3.tgz
 
 
 
–解压
 
[root@njdyw python]# tar -zvxf Python-2.7.3.tgz
 
[root@njdyw python]# ls
 
Python-2.7.3  Python-2.7.3.tgz
 
 
 
–configure:避免对原有的Python产生影响,必须制定prefix。
 
[root@njdyw python]# cd Python-2.7.3
 
[root@njdyw Python-2.7.3]# ./configure –prefix=/usr/local/python2.7.3
 
 
 
–make:
 
[root@njdyw Python-2.7.3]# make
 
 
 
–make install:
 
[root@njdyw Python-2.7.3]# make install
 
 
 
安装成功后目录为:
 
[root@njdyw Python-2.7.3]# ll /usr/local/python2.7.3/
 
总计 16
 
drwxr-xr-x 2 root root 4096 03-21 10:12 bin
 
drwxr-xr-x 3 root root 4096 03-21 10:07 include
 
drwxr-xr-x 4 root root 4096 03-21 10:07 lib
 
drwxr-xr-x 3 root root 4096 03-21 10:07 share
 
 
 
–建立软链接:
 
[root@njdyw Python-2.7.3]# ln -s /usr/local/python2.7.3/bin/python /bin/python2.7.3
 
[root@njdyw Python-2.7.3]# python
 
python      python2      python2.4    python2.7.3
 
[root@njdyw Python-2.7.3]# python2.7.3
 
Python 2.7.3 (default, Mar 21 2013, 10:06:48)
 
[GCC 4.1.2 20080704 (Red Hat 4.1.2-50)] on linux2

>>>3.安装setuptools
 
 
 
–使用wget下载:
 
[root@njdyw Python]# pwd
 
/python
 
[root@njdyw python]#wget http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz#md5=7df2a529a074f613b509fb44feefe74e
 
[root@njdyw python]# ls
 
Python-2.7.3  Python-2.7.3.tgz  setuptools-0.6c11.tar.gz
 
 
 
 
 
–解压:
 
[root@njdyw python]# tar xzvf setuptools-0.6c11.tar.gz
 
[root@njdyw python]# ls
 
Python-2.7.3  Python-2.7.3.tgz  setuptools-0.6c11  setuptools-0.6c11.tar.gz
 
 
 
–安装:
 
[root@njdyw setuptools-0.6c11]# python2.7.3 setup.py install
 
 
 
 
 
–建立软链接:
 
[root@njdyw setuptools-0.6c11]#ln -s /usr/local/python2.7.3/bin/easy_install /bin/easy_install2.7.3
 
 
 
4.测试使用easy_install
 
[root@njdyw setuptools-0.6c11]# easy_install2.7.3 numpy
