Centos 6.4 安装python

Centos自带的python版本太低，所以自己编译安装下python 2.7.10

安装需要的包:

[root@python ~]# yum -y install wget

[root@python ~]# yum -y install gcc

[root@python ~]# wget https://www.python.org/ftp/python/2.7.10/Python-2.7.10.tgz

[root@python ~]# tar xf Python-2.7.10.tgz 

[root@python ~]# cd Python-2.7.10

[root@python Python-2.7.10]# ./configure --prefix=/usr/local/python2.7.10

[root@python Python-2.7.10]# make

[root@python Python-2.7.10]# make install

备份系统自带的python:

[root@python Python-2.7.10]# mv /usr/bin/python /usr/bin/python_bak

[root@python Python-2.7.10]# ln -s /usr/local/python2.7.10/bin/python /usr/bin/python

查看python版本:

[root@python Python-2.7.10]# python

Python 2.7.10 (default, Dec  4 2015, 22:22:15) 

[GCC 4.4.7 20120313 (Red Hat 4.4.7-16)] on linux2

Type "help", "copyright", "credits" or "license" for more information.

>>> exit()

安装之后yum不能用了，修改yum文件的第一行即可

[root@python ~]# which yum

/usr/bin/yum

[root@python ~]# vi /usr/bin/yum 

#!/usr/bin/python_bak

解决Python2.7.10交互模式中方向键、退格键乱码问题。安装readline-devel，装完后重新编译安装python才可以使用。

[root@python ~]# yum -y install readline-devel
