CentOS7 安装Python开发环境

1、使用xshell登录到我们的CentOS7系统

2、添加CentOS SCLo存储库

[root@linuprobe ~]# yum -y install centos-release-scl-rh centos-release-scl

2、使用yum安装python3.3

[root@linuprobe ~]# scl enable python33 bash #加载环境变量

[root@linuprobe ~]# python -V 

Python 3.3.2

[root@linuprobe ~]# which python 

/opt/rh/python33/root/usr/bin/python

[root@linuprobe ~]# vi /etc/profile.d/python33.sh

#!/bin/bash

source /opt/rh/python33/enable

export X_SCLS="`scl enable python33 'echo $X_SCLS'`"

3、使用yum安装python

[root@linuprobe ~]# scl enable python34  bash #加载环境变量

[root@linuprobe ~]# python -V 

Python 3.4.2

[root@linuprobe ~]# which python 

/opt/rh/python34 /root/usr/bin/python

[root@linuprobe ~]# vi /etc/profile.d/python34 .sh

#!/bin/bash

source /opt/rh/python34 /enable

export X_SCLS="`scl enable python34  'echo $X_SCLS'`"

4、使用yum安装Python3.5

[root@linuprobe ~]# scl enable python35  bash #加载环境变量

[root@linuprobe ~]# python -V 

Python 3.5.1

[root@linuprobe ~]# which python 

/opt/rh/python35 /root/usr/bin/python

[root@linuprobe ~]# vi /etc/profile.d/python35 .sh

#!/bin/bash

source /opt/rh/python35 /enable

export X_SCLS="`scl enable python35  'echo $X_SCLS'`"
