Install Python 2.7.X on CentOS 6.X

The Python version of the CentOS 6.X comes with 2.6, and many times it requires 2.7 versions due to the work required. Therefore, a version upgrade is required. Because some system tools and services are dependent on Python, it is important to upgrade the Python version.

Upgrade steps

How joyful, no pain upgrade Python version, look down ...

Updating the system and development toolset

Update instructions

yum -y updateyum groupinstall -y ‘development tools‘

Additional packages required to install Python tools SSL, bz2, zlib

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

Source Installation Python 2.7.x

http://www.python.org/ftp/python/2.7.8/Python-2.7.8.tar.xzxz -d Python-2.7.8.tar.xztar -xvf Python-2.7.8.tar

Installation details:

# 进入目录:cd Python-2.7.8# 运行配置 configure:./configure --prefix=/usr/local# 编译安装:makemake altinstall# 检查 Python 版本:[[email protected] ~]# python2.7 -VPython 2.7.8

Set PATH

In order for us to be able to use Python conveniently, we need to set the system variables or establish a soft connection to make the new version of Python
Add to the directory that corresponds to path:

export PATH="/usr/local/bin:$PATH"or ln -s /usr/local/bin/python2.7 /usr/bin/python# 检查[root@dbmasterxxx ~]# python -VPython 2.7.8[root@dbmasterxxx ~]# which python /usr/bin/python

Installing Setuptools

#获取软件包wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-1.4.2.tar.gz# 解压:tar -xvf setuptools-1.4.2.tar.gzcd setuptools-1.4.2# 使用 Python 2.7.8 安装 setuptoolspython2.7 setup.py install

Install PIP

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

Fix Yum Tool

Yum should be invalidated at this point because the default Python version is now 2.7. and Yum needs 2.6, so:

[root@dbmasterxxx ~]# which yum /usr/bin/yum#修改 yum中的python 将第一行  #!/usr/bin/python  改为 #!/usr/bin/python2.6此时yum就ok啦

Summarize
