[记录]CentOS 6中Python从2.6升级到2.7

CentOS crifan 1273浏览 0评论

折腾:

[记录]CentOS中安装和使用virtualenv

期间,要去把CentOS 6中的Python 2.6,升级到Python 2.7

但是要确保:

好像有人提到的:yum依赖于python 2.6

所以就是:

由于系统其它一些功能,要依赖于python 2.6

所以要升级Python 到2.7

却还要保证,不影响系统的其它功能,比如yum

centos 6 yum install python 2.7

阿里云yum升级python2.7 CentOS默认自带pyton2.6 一介布衣

然后尝试去安装:

直接去:

yum install -y python27

是不行的:

 jiandaoweixin yum install -y python27

改为

如图:

 setuptools-25.2.0 cat /usr/bin/yum
#!/usr/bin/python2.6
。。。

[总结]

1.更新系统库

yum -y update
yum groupinstall -y ‘development tools’

安装 python 工具需要的额外软件包 SSL, bz2, zlib

yum install -y zlib-devel bzip2-devel openssl-devel xz-libs wget

注:

后来又需要sqlite,所以也最好加航:

yum install -y sqlite-devel

2.找到Python 2的最新的版本和下载地址:

Index of /ftp/python/

->中,找到Python 2最新的版本,此处是2.7.12:

https://www.python.org/ftp/python/2.7.12/

-》

里面的要下载的是:

https://www.python.org/ftp/python/2.7.12/Python-2.7.12.tar.xz

-》

去通过源码下载和解压Python:

wget https://www.python.org/ftp/python/2.7.12/Python-2.7.12.tar.xz
xz -d Python-2.7.12.tar.xz
tar -xvf Python-2.7.12.tar

通过源码安装Python:

cd Python-2.7.12
./configure –prefix=/usr/local
make
make altinstall

确认已经安装成功,查看版本:

export PATH="/usr/local/bin:$PATH"
python2.7 -V

3.找到最新版本的setuptools:

setuptools 25.2.0 : Python Package Index

-》

找到最新版本,此处是25.2.0:

setuptools-25.2.0.tar.gz (md5)

右击可以拷贝下载链接地址:

https://pypi.python.org/packages/9f/32/81c324675725d78e7f6da777483a3453611a427db0145dfb878940469692/setuptools-25.2.0.tar.gz#md5=a0dbb65889c46214c691f6c516cf959c

-》去掉md的后缀,变为:

https://pypi.python.org/packages/9f/32/81c324675725d78e7f6da777483a3453611a427db0145dfb878940469692/setuptools-25.2.0.tar.gz

-》下载setuptools的源码并安装:

wget –no-check-certificate https://pypi.python.org/packages/9f/32/81c324675725d78e7f6da777483a3453611a427db0145dfb878940469692/setuptools-25.2.0.tar.gz
tar -xvf setuptools-25.2.0.tar.gz
cd setuptools-25.2.0
python2.7 setup.py install

下载和安装PIP:

curl https://bootstrap.pypa.io/get-pip.py | python2.7 –

4.设置默认Python为最新版本的Python:

rm /usr/bin/python
ln -s /usr/local/bin/python2.7  /usr/bin/python
ls -l /usr/bin/py*

注意:

此处应该是第三步的时候,直接食用make install而不是make altinstall

估计就可以自动让python 2.7变成默认的Python了。

就无需此步骤了。

5.修复yum

which yum
vi /usr/bin/yum

把:

将第一行的

#!/usr/bin/python

改为

#!/usr/bin/python2.6
