查看python的版本

[plain] view plain copy

print?

#python -V
Python 2.6.6

1.下载Python-2.7.5至/usr/local/

[plain] view plain copy

print?

#wget https://python.org/ftp/python/2.7.5/Python-2.7.5.tar.bz2

2.解压

[plain] view plain copy

print?

#tar -jxvf Python-2.7.5.tar.bz2

3.更改工作目录

[plain] view plain copy print?

#cd Python-2.7.5

4.安装

[plain] view plain copy

print?

#./configure --enable-unicode=ucs4
#make all
#make install
#make clean
#make distclean

编译之后，会在/usr/local/bin/目录生成相关python的文件

5.查看版本信息

[plain] view plain copy

print?

#/usr/local/bin/python2.7 -V

6.建立软连接，使系统默认的 python指向 python2.7

[plain] view plain copy

print?

#mv /usr/bin/python /usr/bin/python2.6.6
#ln -s /usr/local/bin/python2.7 /usr/bin/python

7.重新检验Python 版本

[plain] view plain copy

print?

#python -V

8解决系统 Python 软链接指向 Python2.7 版本后，因为yum是不兼容 Python 2.7的，所以yum不能正常工作，我们需要指定 yum 的Python版本

[plain] view plain copy

print?

#vi /usr/bin/yum

将文件头部的
#!/usr/bin/python

改成
#!/usr/bin/python2.6.6
