RedHat升级Python到2.7.6
来源：Linux社区&
作者：benbenxiong
从今天开始学习Python!看了一下虚拟机中的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 :10)[GCC 4.1.2
( 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 http://python.org/ftp/python/2.7.6/Python-2.7.6.tgz
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 :09) [GCC 4.1.2
(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 :09) [GCC 4.1.2
(Red Hat 4.1.2-44)]
If you cannot solve this problem yourself, please go to the yum faq at:& http://wiki.linux.duke.edu/YumFaq
[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!

GO_LOHAS的博客
分类：python
简单记录下，centos6.x 上安装 python2.7.x 过程：
1、系统版本：CentOS-6.8-x86_64-minimal.iso
1&安装前准备：
保证系统能上网然后用yum命令安装以下软件：make、zlib-devel、bzip2-devel、openssl-devel、ncurses-devel、sqlite-devel、gcc&
命令安装举例：
安装make： yum install make &&
python官网下载python2.7.x的源码包，然后解压 tar -zvxf &Python-2.7.11.tgz
2&安装python
进入解压包 cd python-2.7.11，我要把python安装到目录 /usr/local 下，所以
./configure --prefix=/usr/local
make&&make altinstall
3&安装完成后，设置python的环境：
进入/etc/profile.d/ 目录，创建 python.sh 文件并添加如下内容：
创建文件命令 &vim python.sh （如果没有vim命令，可以用vi）
export PATH=”/usr/local/bin:$PATH”&
添加完成之后保存文件，重启系统 init 6
4&安装setuptoool
wget --no-check-certificate（如果没有wget命令，可以用yum
install wget 安装）
python ez_setup.py –insecure
wget--no-check-certificate
tar -zxvf 1.5.5.tar.gz
python setup.py install
pip自升级：pip install -U pip
到这里安装就差不多了。如果想安装插件的话，直接用pip install 就可以了。

先声明下，本以为在centos下升级python很easy,，没想到是个大坑。有的能装好，但是不能用。各种缺失吧，非常蛋疼。
下面整理下思路，从python2.6.X升级到python2.7.9,同时安装了setuptools以及pip
1、从python2.6.X升级python到2.7.9
& &&CentOS 6.X默认的Python版本都是2.6 ，需要升级到2.7以及安装pip方法如下：
yum install bzip2 bzip2-devel -y
yum install zlib zlib-devel -y
yum install openssl openssl-devel -y
下载python2.7源码,编译安装：wget https://www.python.org/ftp/python/2.7.9/Python-2.7.9.tgz
tar zxvf Python-2.7.9.tgz
cd Python-2.7.9
./configure
make install然后需要配置一下# 建立软链接，默认指向Python2.7
mv /usr/bin/python /usr/bin/python2.6_temp
ln -s /usr/local/bin/python2.7 /usr/bin/python
# Python 2.7.9
# yum不兼容Python2.7，需要指定为原版本
vi /usr/bin/yum
# 将&!/usr/bin/python&改为&!/usr/bin/python2.6&
# 环境变量
vi /etc/profile
# 添加如下内容：
PY_HOME=/usr/local/bin/python2.7
export PATH=$PY_HOME/bin:$PATH
source /etc/profile
# 当前终端生效，reboot后才会完全生效
echo $PATH如果你升级python失败，用这个方法，这个方法可以直接搞定！
解决交互式乱码问题
（参考 http://blog.csdn.net/clevercode/article/details/）
2）解决方案。这个问题主要是由于缺少readline Module问题导致的。而CentOS默认只有readline模块而没有readline-devel开发模块。所以只要安装下即可。# yum -y install readline-devel
重新编译安装python# cd
#回到解压目录# ./configure # make &
#编译# make install
2、安装setuptools
wget https://pypi.python.org/packages/6b/dd/a7de8caeeffab76bacfc12e0ae6932245abbce6/setuptools-28.3.0.tar.gz#md5=aab0e2721a
tar zxvf setuptools-28.3.0.tar.gz&
cd setuptools-28.3.0
python setup.py install
3、安装pip
wget https://pypi.python.org/packages/e7/a8/add8d1a54c0b14aeff0acb03c6ecd5/pip-8.1.2.tar.gz#md5=aba
tar pip-8.1.2.tar.gz&
tar zxvf &pip-8.1.2.tar.gz&
cd pip-8.1.2&
python setup.py install
