centos7.2构建Python3.5开发环境

1.本次使用的是一台全新的腾讯云主机,首先获取linux系统版本信息。

[root@VM_46_121_centos ~]# cat /etc/redhat-release

<本系统默认自带python2.7.5>

[root@VM_46_121_centos ~]# python

Python 2.7.5 (default, Sep 15 2016, 22:37:39)

[GCC 4.8.5 20150623 (Red Hat 4.8.5-4)] on linux2

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

CentOS Linux release 7.2.1511 (Core)

2.因为后期要用到pip3,所以先安装openssl,openssl-devel。

[root@VM_46_121_centos ~]# yum -y install openssl openssl-devel

3.下载编译安装python3.5,记的先下载gcc-c++!

[root@VM_46_121_centos ~]# cd /usr/local/src/

[root@VM_46_121_centos src]# wget https://www.python.org/ftp/python/3.5.2/Python-3.5.2.tgz

[root@VM_46_121_centos src]# tar -zxvf Python-3.5.2.tgz

[root@VM_46_121_centos src]# cd Python-3.5.2/

[root@VM_46_121_centos Python-3.5.2]# ./configure && make all && make install

[root@VM_46_121_centos Python-3.5.2]# python3

Python 3.5.2 (default, Apr 21 2017, 16:32:19)

[GCC 4.8.5 20150623 (Red Hat 4.8.5-11)] on linux

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

4.如果你想升级python版本到python3.5的话,如下操作。

[root@VM_46_121_centos Python-3.5.2]# mv /usr/bin/python /usr/bin/python2.6

[root@VM_46_121_centos Python-3.5.2]# ln -s /usr/local/bin/python3.5 /usr/bin/python

别忘了vim /usr/bin/yum

解决升级python导致yum不可用的问题!

5.因为我喜欢玩ipython所以使用pip3安装了。

[root@VM_46_121_centos Python-3.5.2]# pip3 install ipython

6.现在python3.5环境是没有任何问题的!需要执行什么py脚本直接python3.5+脚本即可!

[root@VM_46_121_centos python]# python3.5 simple.py
