centos系统下安装python

下载：

wget -c http://www.python.org/ftp/python/3.1.3/Python-3.1.3.tar.bz2
解压编译安装：

$ tar –jxvf Python-2.5.2.tar.bz2

$ cd Python-2.5.2

$ ./configure

$ make

$ make install

由于centos默认安装有2.4，直接输入python进行的是2.4

# python

Python 2.4.3 (#1, Dec 11 2006, 11:38:52)

[GCC 4.1.1 20061130 (Red Hat 4.1.1-43)] on linux2

Type “help”, “copyright”, “credits” or “license” for more information.

>>>

如下修改可以解决

cd /usr/bin

ll |grep python

ln -s /root/Python-3.1.3/python ./python ///root/Python-3.1.3/python为解压目录

现在输入python显示为3.1的了

[root@chxy bin]# python

Python 3.1.3 (r313:86834, Jan 2 2011, 02:12:38)

[GCC 4.1.2 20080704 (Red Hat 4.1.2-48)] on linux2
