RedHat升级Python到2.7.6

python，发现还是原生的2.4.3，所以决定升级一下

[root@linuxidc ~]# python
Python 2.4.3 (#1, May  5 2011, 16:39:10)
>>>
[root@linuxidc ~]#

1.下载z最新版本的python

[root@linuxidc ~]# wget http://python.org/ftp/python/2.7.6/Python-2.7.6.tgz
可以在windows上下载后上传

2.解压及编译

[root@linuxidc ~]# tar xvf Python-2.7.2.tar.bz2
[root@linuxidc Python-2.7.6]# ./configure --prefix=/usr/local/python27
[root@linuxidc Python-2.7.6]# make
[root@linuxidc Python-2.7.6]# make install

[root@linuxidc Python-2.7.6]# ls /usr/local/python27/ -al
total 28
drwxr-xr-x  6 root root 4096 Mar 21 01:01 .
drwxr-xr-x 13 root root 4096 Mar 21 01:01 ..

3.覆盖原有的python链接

[root@linuxidc Python-2.7.6]# mv /usr/bin/python /usr/bin/python_old
[root@linuxidc Python-2.7.6]# ln -s /usr/local/python27/bin/python /usr/bin/python
[root@linuxidc Python-2.7.6]# python
