4 바꿔치기

[root@jmnote ~]# ll /usr/bin/python*
-rwxr-xr-x 1 root root    8304 Sep 22  2011 /usr/bin/python
lrwxrwxrwx 1 root root       6 Nov  1  2011 /usr/bin/python2 -> python
-rwxr-xr-x 1 root root    8304 Sep 22  2011 /usr/bin/python2.4

[root@jmnote Python-2.7.4]# cd
[root@jmnote ~]# /usr/bin/python -V
Python 2.4.3

[root@jmnote ~]# /usr/local/bin/python2.7 -V
Python 2.7.4

구버전은 python_old로 이름을 바꾸고 신버전을 python이라는 이름으로 복사한다.

[root@jmnote ~]# mv /usr/bin/python /usr/bin/python_old
[root@jmnote ~]# cp /usr/local/bin/python2.7 /usr/bin/python
[root@jmnote ~]# python -V
Python 2.7.4

5 yum 오류 고치기

python에 의존성이 있던 yum이 제대로 작동하지 않는다...

[root@jmnote ~]# yum
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

   No module named yum

Please install a package which provides this module, or
verify that the module is installed correctly.

It's possible that the above module doesn't match the
current version of Python, which is:
2.7.4 (default, Apr 14 2013, 12:44:22) 
[GCC 4.1.2 20080704 (Red Hat 4.1.2-54)]

If you cannot solve this problem yourself, please go to 
the yum faq at:
  http://wiki.linux.duke.edu/YumFaq

다음과 같이 /usr/bin/yum 파일을 수정하자.

[root@jmnote ~]# cp /usr/bin/yum /usr/bin/yum_old
[root@jmnote ~]# sed -i 's/\/usr\/bin\/python/\/usr\/bin\/python2.4/g' /usr/bin/yum
[root@jmnote ~]# diff /usr/bin/yum_old /usr/bin/yum
1c1
< #!/usr/bin/python
---
> #!/usr/bin/python2.4

→ 파일의 1행에 있는 #!/usr/bin/python를 #!/usr/bin/python2.4로 수정하였다...

[root@jmnote ~]# yum
... (생략)
  --samearch-priorities
                        Priority-exclude packages based on name + arch

  Plugin Options:

→ 이제 잘 된다.
