备份旧python相关命令

===> 有些版本/usr/bin/目录下不存在pip 或者easy_install 忽略下面第1,2行命令即可
[root@cdh-server1 ~]#  mv /usr/bin/pip /usr/bin/pip_old  
[root@cdh-server1 ~]# mv /usr/bin/easy_install /usr/bin/easy_install_old
[root@cdh-server1 ~]# mv /usr/bin/python /usr/bin/python_old

新版本python命令做软连接，快捷使用

[root@server2 Python-2.7.13]# ln -s /usr/local/python2.7/lib/libpython2.7.so /usr/lib
[root@server2 Python-2.7.13]# ln -s /usr/local/python2.7/lib/libpython2.7.so.1.0 /usr/lib
[root@server2 Python-2.7.13]# ln -s /usr/local/python2.7/bin/python2.7 /usr/bin/python
[root@server2 Python-2.7.13]# ln -s /usr/local/python2.7/lib/libpython2.7.so /usr/lib64
[root@server2 Python-2.7.13]# ln -s /usr/local/python2.7/lib/libpython2.7.so.1.0 /usr/lib64

测试python是否可以正常使用

[root@server2 ~]# python
