1、安装好CentOS7.0 ：

[root@localhost ~]# cat /proc/version

Linux version 3.10.0-229.el7.x86_64 (builder@kbuilder.dev.centos.org) (gcc version 4.8.2 20140120 (Red Hat 4.8.2-16) (GCC) ) #1 SMP Fri Mar 6 11:36:42 UTC 2015

[root@localhost ~]#

2、确保liunx主机能上互联网：

[root@localhost ~]# nslookup

> www.python.org

Server: 192.168.8.254

Address: 192.168.8.254#53

Non-authoritative answer:

www.python.org canonical name = python.map.fastly.net.

python.map.fastly.net canonical name = prod.python.map.fastlylb.net.

Name: prod.python.map.fastlylb.net

Address: 151.101.36.223

>

3、下载python安装包：

[root@localhost ~]# wget https://www.python.org/ftp/python/3.5.0/Python-3.5.0b4.tgz

--2016-06-21 15:32:23-- https://www.python.org/ftp/python/3.5.0/Python-3.5.0b4.tgz

正在解析主机 www.python.org (www.python.org)... 151.101.36.223

正在连接 www.python.org (www.python.org)|151.101.36.223|:443... 已连接。

正在保存至: “Python-3.5.0b4.tgz”

[root@localhost ~]#

4、解压安装python：

[root@localhost ~]# ll

总用量 16320

-rw-r--r--. 1 root root 16664311 6月 21 15:40 Python-3.5.0b4.tgz

[root@localhost ~]# tar -zxvf Python-3.5.0b4.tgz

[root@localhost ~]# ll

总用量 19520

drwxrwxr-x. 16 1000 1000 4096 7月 26 2015 Python-3.5.0b4

-rw-r--r--. 1 root root 19980637 7月 26 2015 Python-3.5.0b4.tgz

[root@localhost ~]# cd Python-3.5.0b4/

[root@localhost Python-3.5.0b4]# ./configure

[root@localhost Python-3.5.0b4]# make

[root@localhost Python-3.5.0b4]# make install

看到以下信息，说明python安装完成：第二行会因liunx的版本不一样而异同，请留意！

[root@localhost Python-3.5.0b4]# python

Python 2.7.5 (default,Jun 17 2014,18:11:42)
