从今天开始学习Python!看了一下虚拟机RedHat中的python，发现还是原生的2.4.3，所以决定升级一下
[root@linuxidc ~]# pythonPython 2.4.3 (#1, May 5 2011, 16:39:10)[GCC 4.1.2 20080704 (Red Hat 4.1.2-50)] on linux2Type “help”, “copyright”, “credits” or “license” for more information.>>>[root@linuxidc ~]#
1.下载z最新版本的python
[root@linuxidc ~]# wget
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/ -altotal 28drwxr-xr-x 6 root root 4096 Mar 21 01:01 .drwxr-xr-x 13 root root 4096 Mar 21 01:01 ..drwxr-xr-x 2 root root 4096 Mar 21 01:01 bindrwxr-xr-x 3 root root 4096 Mar 21 01:01 includedrwxr-xr-x 4 root root 4096 Mar 21 01:01 libdrwxr-xr-x 3 root root 4096 Mar 21 01:01 share
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/[root@linuxidc Python-2.7.6]# pythonPython 2.7.6 (default, Mar 21 2014, 01:00:09) [GCC 4.1.2 20080704 (Red Hat 4.1.2-44)] on linux2Type “help”, “copyright”, “credits” or “license” for more information.>>>
此时已经可以正常使用python2.7了，但是因为yum是使用的2.4的版本来用的，，现在输入一下yum就会报错
[root@linuxidc Python-2.7.6]# yumThere was a problem importing one of the Python modulesrequired to run yum. The error leading to this problem was:
No module named yum
Please install a package which provides this module, orverify that the module is installed correctly.
It’s possible that the above module doesn’t match thecurrent version of Python, which is:2.7.6 (default, Mar 21 2014, 01:00:09) [GCC 4.1.2 20080704 (Red Hat 4.1.2-44)]
If you cannot solve this problem yourself, please go to the yum faq at:
5.修改yum
[root@linuxidc Python-2.7.6]# vim /usr/bin/yum
#!/usr/bin/python #修改此处为2.4的位置
[root@linuxidc Python-2.7.6]# vim /usr/bin/yum
#!/usr/bin/python2.4
yum 可以使用了!
