centos 升级python2.6 到python3.3

  Centos 6.5版本发布了，但是里面使用的python却是2.6.6的版本，对于想使用python新版本的朋友，可以自己升级python。

1.查看当前python的版本。

[root@localhost liukk]# python
Python 2.6.6 (r266:84292, Nov 22 2013, 12:16:22) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2

>>> 

2. 安装升级相应的软件包。

 yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make

3. 下载python 3.3 的源码包。

[root@localhost liukk]# wget http://mirrors.sohu.com/python/3.3.3/Python-3.3.3.tar.bz2
--2013-12-24 06:10:56--  http://mirrors.sohu.com/python/3.3.3/Python-3.3.3.tar.bz2

 4. 安装python3.3

  

 tar jxvf Python-3.3.3.tar.bz2 -C /usr/local/src/
  cd /usr/local/src/Python-3.3.3/
  ./configure --prefix=/usr/local/python3.3
  make && make install

  安装完之后可以在/usr/local/src/python3.3/bin 目录下看到python3.3

5. 配置python

  

 mv /usr/bin/python /usr/bin/python.bak
 ln -s /usr/local/python3.3/bin/python3.3 /usr/bin/python

6. 查看当python的版本

[root@localhost bin]# python
Python 3.3.3 (default, Dec 24 2013, 06:29:34) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux

 至此，centos python3.3 版本安装完毕，可以尽情遨游python coding 了。
