CentOS安裝python-2.7+安裝pip-10.0.0

標籤：安裝   64位   package   class   clu   x86   style   python安裝   profile   

 

註：以下所有操作均在CentOS 6.8 x86_64位系統下完成。

 

首先查看當前系統預裝的python版本：

# whereis pythonpython2: /usr/bin/python2 /usr/bin/python2.6 /usr/lib/python2.6 /usr/lib64/python2.6 /usr/include/python2.6# pthyon --versionPython 2.6.6# cd /usr/bin# ls -l python*-rwxr-xr-x 2 root root 4864 Aug 18  2016 pythonlrwxrwxrwx 1 root root    6 Aug 24  2017 python2 -> python-rwxr-xr-x 2 root root 4864 Aug 18  2016 python2.6

系統預設安裝的是python-2.6.6，由於2.6版本已經不再被支援，所以這裡將其升級成2.7版本。

#安裝python#

開始下載python並進行編譯安裝：

# wget https://www.python.org/ftp/python/2.7/Python-2.7.tgz# tar zxf Python-2.7.tgz# cd Python-2.7# ./configure --prefix=/usr/local/python-2.7# make && make install

然後配置環境替換預設的python-2.6：

# vim /etc/profile...export PY_HOME=/usr/local/python-2.7export PATH=$PY_HOME/bin:$PATH...# source /etc/profile# python --versionPython 2.7

重新指向python2的軟鏈：

# rm -f /usr/bin/python2# ln -s /usr/local/python-2.7/bin/python /usr/bin/python2

至此，python安裝完畢。

#安裝pip#

首先查看當前的pip的版本：

# whereis pippip: /usr/bin/pip /usr/bin/pip2.6# pip --versionpip 9.0.1 from /usr/lib/python2.6/site-packages (python 2.6)

當前的pip是python2.6的，所以同樣需要升級安裝。

首先需要安裝setuptools：

# wget https://files.pythonhosted.org/packages/72/c2/c09362ab29338413ab687b47dab03bab4a792e2bbb727a1eb5e0a88e3b86/setuptools-39.0.1.zip# unzip setuptools-39.0.1.zip# cd setuptools-39.0.1# python setup.py install...Installed /usr/local/python-2.7/lib/python2.7/site-packages/setuptools-39.0.1-py2.7.eggProcessing dependencies for setuptools==39.0.1Finished processing dependencies for setuptools==39.0.1

然後安裝pip：

# wget https://files.pythonhosted.org/packages/e0/69/983a8e47d3dfb51e1463c1e962b2ccd1d74ec4e236e232625e353d830ed2/pip-10.0.0.tar.gz# tar zxf pip-10.0.0.tar.gz# cd pip-10.0.0# python setup.py install...Installed /usr/local/python-2.7/lib/python2.7/site-packages/pip-10.0.0-py2.7.eggProcessing dependencies for pip==10.0.0Finished processing dependencies for pip==10.0.0

然後配置環境替換預設的pip：

# which pip/usr/local/python-2.7/bin/pip# source /etc/profile# pip --versionpip 10.0.0 from /usr/local/python-2.7/lib/python2.7/site-packages/pip-10.0.0-py2.7.egg/pip (python 2.7)

至此，安裝完成。
