Centos安装pip和elasticsearch模块基本使用

CentOS安装python包管理安装工具pip的方法如下：

# wget --no-check-certificate https://github.com/pypa/pip/archive/1.5.5.tar.gz
# mv 1.5.5 1.5.5.tar.gz
# tar zxf 1.5.5.tar.gz
# cd pip-1.5.5/
# python setup.py install
验证:
# pip -V
pip 1.5.5 from /usr/lib/python2.6/site-packages/pip-1.5.5-py2.6.egg (python 2.6)

安装elasticsearch模块如下：

# pip install elasticsearch

使用示例如下：

>>> from datetime import datetime
[quote]>> from elasticsearch import Elasticsearch[/quote]

# 默认情况下我们连接 localhost:9200
[quote]>> es = Elasticsearch()[/quote]

# datetimes 将序列化
[quote]>> es.index(index="my-index", doc_type="test-type", id=42, body={"any": "data", "timestamp": datetime.now()})
{u'_id': u'42', u'_index': u'my-index', u'_type': u'test-type', u'_version': 1, u'ok': True}[/quote]

# 但不是反序列化
[quote]>> es.get(index="my-index", doc_type="test-type", id=42)['_source']
{u'any': u'data', u'timestamp': u'2013-05-12T19:45:31.804229'}
