centos安装python2.7并安装easy_install,pip,ipython
1.安装python
下载python2.7.10
# wget https://www.python.org/ftp/python/2.7.10/Python-2.7.10.tgz
# tar -zxvf Python-2.7.10.tgz
# cd Python-2.7.10
# ./configure --prefix=/usr/local/python
# make && make install
然后测试python是否安装成功
# /usr/local/python/bin/python2.7
Python 2.7.10 (default, Aug 26 2015, 22:48:01)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-16)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
建立软连接
# mv /usr/bin/python /usr/bin/python26
# ln -s /usr/local/python/bin/python2.7 /usr/bin/python
因为升级python,会导致yum不可用,解决方法如下:
#vi /usr/bin/yum
将文件头行
#!/usr/bin/python
2.安装easy_install和pip
easy_install和pip都是用来下载安装Python一个公共资源库PyPI的相关资源包的
首先安装easy_install
# wget https://pypi.python.org/packages/source/e/ez_setup/ez_setup-0.9.tar.gz
# tar -zxvf ez_setup-0.9.tar.gz
# cd ez_setup-0.9
# python ez_setup.py
# ln -s /usr/local/python/bin/easy_install /usr/bin/easy_install
安装好easy_install 之后 再安装pip
# wget --no-check-certificate https://pypi.python.org/packages/source/p/pip/pip-7.1.2.tar.gz
# tar -zxvf pip-7.1.2.tar.gz
# cd pip-7.1.2
# python setup.py install
# ln -s /usr/local/python/bin/pip /usr/bin/pip
3.安装ipython
首先要装readline
# pip install readline
然后直接安装ipython
# pip install ipython
装上pip和easy_install,以后装任何模块都很轻松了
