python → python3 → python3.6으로 설정
[root@localhost ~]# ln -s /bin/python3.6 /bin/python3
python은 yum에서 사용하므로 python3을 python으로 link했을때는 yum 사용시 오류가 발생합니다.
다시 python2을 python으로 link해야 하므로 python3까지만 link해도 좋을 듯합니다.
[root@localhost ~]# unlink /bin/python
[root@localhost ~]# ln -s /bin/python3 /bin/python

[root@localhost ~]# python3 -V
