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'`"
