（linux）python之setuptools、easyinstall、pip安装及连接redis

python ez_setup.py报错：

然后只能手动帮助它下载了哈

wget http://pypi.python.org/packages/source/d/distribute/distribute-0.6.14.tar.gz

结果又报错：

提示信息是To connect to pypi.python.org insecurely, use ‘--no-check-certificate’.

然后后面加上就ok了

wget http://pypi.python.org/packages/source/d/distribute/distribute-0.6.14.tar.gz --no-check-certificate

结束之后再进行最开始的步骤，就ok了

最近研究python，从0开始研究。看了几天基础开始尝试连接redis，遇到好多问题。在此根据自己的经历总结一下。

一般linux会自带python，版本不一，建议不要删除原有版本，如果没有安装需要首先安装

1、安装python2.7

wget http://python.org/ftp/python/2.7.2/Python-2.7.2.tgz

tar xvf Python-2.7.2.tgz 

cd Python-2.7.2

./configure --prefix=/usr/local/python27

sudo make

sudo make install

（如果是2.4或其他低版本升级过来  请参考python2.4升级2.7.2）

2、安装python-setuptools

 wget –q http://peak.telecommunity.com/dist/ez_setup.py

python ez_setup.py

显示出Finished processing dependencies for setuptools==0.6c11 说明安装成功

3、安装pip

如果是低版本的 python需要安装hashlib

(小插曲)

Python 2.4 安装 hashlib
首先安装 python-devel, hashlib 编译的时候需要
$ sudo yum install python-devel
下载 hashlib 并安装
$ wget httppypi.python.orgpackagessourcehhashlibhashlib-20081119.zip#md5=46e59db6d5cac34b3344ef0c30d0897f
$ unzip hashlib-20081119.zip
$ cd hashlib-20081119
$ sudo python setup.py install
OK

curl -O https://raw.github.com/pypa/pip/master/contrib/get-pip.py

 python get-pip.py

Downloading/unpacking pip

……

Successfully installed pip
Cleaning up...（完成）

4、安装redis模块

sudo pip install redis

Successfully installed redis（完成）

可以测试redis了！！

>>> import redis
>>> r = redis.Redis(host='localhost', port=6379, db=0)   #如果设置了密码，就加上password=密码
>>> r.set('foo', 'bar')   #或者写成 r['foo'] = 'bar'
True
>>> r.get('foo')   
'bar'
>>> r.delete('foo')
True
>>> r.dbsize()   #库里有多少key，多少条数据
