CentOS 6.3中，Python-2.7.3交互模式下方向鍵、退格鍵等出現亂碼

#安裝readline-devel

# yum install readline-devl

#重新安裝python

1. 準備工作

下載源碼包

如果沒有安裝make工具

~#rpm -qa|grep make

yum -y install gcc automake autoconf libtool make

安裝zlib

yum install zlib-devel

安裝openssl

yum install openssl*

安裝bzip2依賴庫

yum install -y bzip2*

2. 編譯安裝

cp Python-2.7.3.tar.bz2 /usr/src/

tar -jxvf Python-2.7.3.tar.bz2

vi Modules/Setup.dist

找到

#SSL=/usr/local/ssl

#_ssl _ssl.c \

#?????? -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \

#?????? -L$(SSL)/lib -lssl -lcrypto

......

#zlib zlibmodule.c -I$(prefix)/include -L$(exec_prefix)/lib -lz

把注釋去掉

編譯

./configure --prefix=/usr/local/python2.7

makeallmake install

makecleanmake distclean

建立python2.7 軟鏈

~#mv /usr/bin/python /usr/bin/python.bak~#ln -s /usr/local/python2.7/bin/python2.7 /usr/bin/python2.7

~#ln -s /usr/bin/python2.7 /usr/bin/python

3. 解決yum無法使用的問題

~#yum update

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:

2.7.3 (default, Dec 18 2013, 15:43:35)

[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)]

If you cannot solve this problem yourself, please go to

the yum faq at:

http://yum.baseurl.org/wiki/Faq

因為centos 6.3 下yum默認使用的是python2.6

vi /usr/bin/yum

----------------------------------------------------

#!/usr/bin/python

import sys

try:

import yum

except ImportError:

.......

修改為：

#!/usr/bin/python2.6........
