CentOS安装python2.7.9,竟然自己指向了/usr/local/bin,求原因

  • python
  • centos

在CentOS下安装python2.7.9,(下面会粘出操作history),本来以为按照网上说的,需要在/usr/bin下面改名字,做软链接什么的,发现竟然不用,请大神们解答这是一种什么机制。

命令行里输python,人家就是2.7.9版本了:
[fy@VM_70_40_centos bin]$ python
Python 2.7.9 (default, Mar 16 2016, 20:55:54)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-16)] on linux2
Type "help", "copyright", "credits" or "license" for more information.

然后which,人家自己就指向python2.7.9的安装路径了
[fy@VM_70_40_centos bin]$ which python
/usr/local/bin/python

进到/usr/bin目录下查看,依旧是python2.6.6版本
[root@VM_70_40_centos bin]# ./python
Python 2.6.6 (r266:84292, Nov 22 2013, 12:16:22)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.

exit()

附:安装python的history
70 2016-03-16 20:41:52 wget https://www.python.org/ftp/python/2.7.9/Python-2.7.9.tar.xz
71 2016-03-16 20:48:41 ls
