pip 部署

使用环境： centos 6.6  and  python 2.6

1、安装：

pip 包在epel 的yum 源中首先安装epel：

[root@kvm ~]# yum list|grep epel
epel-release.noarch                      6-8                            extras
[root@kvm ~]# yum install epel-release

然后安装python-pip

yum install python-pip

安装完成后，即可使用pip 命令

[root@kvm Flask]# pip -V
pip 1.3.1 from /usr/lib/python2.6/site-packages (python 2.6)

2、修改pip 源：

使用pip官方源发现被墙了，如下：

[root@kvm ~]# pip install virtualenv
Downloading/unpacking virtualenv

Could not fetch URL https://pypi.python.org/simple/virtualenv/: There was a problem confirming the ssl certificate: <urlopen error _ssl.c:477: The handshake operation timed out>
Will skip URL https://pypi.python.org/simple/virtualenv/ when looking for download links for virtualenv
Could not fetch URL https://pypi.python.org/simple/: There was a problem confirming the ssl certificate: <urlopen error _ssl.c:477: The handshake operation timed out>
Will skip URL https://pypi.python.org/simple/ when looking for download links for virtualenv
Cannot fetch index base URL https://pypi.python.org/simple/ Could not fetch URL https://pypi.python.org/simple/virtualenv/: There was a problem confirming the ssl certificate: <urlopen error _ssl.c:477: The handshake operation timed out>
Will skip URL https://pypi.python.org/simple/virtualenv/ when looking for download links for virtualenv
Could not find any downloads that satisfy the requirement virtualenv
No distributions at all found for virtualenv
Storing complete log in /root/.pip/pip.log

于是修改为国内豆瓣源： http://pypi.douban.com/simple/
查看文档： /usr/share/doc/python-pip-1.3.1/docs/configuration.txt 可得：

配置文件路径： * On Unix and Mac OS X the configuration file is: :file:`$HOME/.pip/pip.conf`

修改路径写法：

The names of the settings are derived from the long command line option, e.g.
if you want to use a different package index (``--index-url``) and set the
HTTP timeout (``--default-timeout``) to 60 seconds your config file would
look like this:

.. code-block:: ini

[global]
timeout = 60
index-url = http://download.zope.org/ppix[/code] 
于是，写在/root/.pip/pip.conf （若没有目录则使用mkdir -p /root/.pip  创建一个）文件为：

[global]
timeout = 60
index-url = http://pypi.douban.com/simple/[/code] 
测试：

[root@kvm Flask]# pip install virtualenv
Downloading/unpacking virtualenv
Downloading virtualenv-13.1.2.tar.gz (1.7MB): 1.7MB downloaded

至此，pip已经可以正常使用

3、pip 参数说明

后续再补充，嘿嘿
