一、安装:

python mongodb驱动: pymongo-2.1.1.tar.gz

python 主程序： Python-2.7.2.tgz

1. 安装python

cd python/tar -xvf Python-2.7.2.tgzcd Python-2.7.2./configure --prefix=$HOME/mongodb/tools/python2.7make ; make install

2. 安装pymongo

cd python/tar -xvf pymongo-2.1.1.tar.gzcd pymongo-2.1.1python setup.py install

二、命令测试

1. 查询一行：

[aiobs8@aiobs8 python]$ pythonPython 2.7.2 (default, Sep 21 2012, 09:54:17) [GCC 4.1.1 20070105 (Red Hat 4.1.1-52)] on linux2Type "help", "copyright", "credits" or "license" for more information.>>> from pymongo import Connection >>> conn = Connection('localhost',27017);>>> db = conn.db>>> test = db.test>>> test.find_one();{u'_id': ObjectId('505bc6c0848e6c0a30d789ee'), u'id': 1, u'name': u'wangyf'}>>>

2. 插入一行数据：

>>> test.insert({'id':2,'name':'w2'})ObjectId('505d3fb207a15601a9000000')

3. 查询多行：

for str in test.find():    str{u'_id': ObjectId('505bc6c0848e6c0a30d789ee'), u'id': 1, u'name': u'wangyf'}{u'_id': ObjectId('505d3fb207a15601a9000000'), u'id': 2, u'name': u'w2'}

4. 查询用户名为w2的记录

>>> for str in test.find({'name':'w2'}):...     str... {u'_id': ObjectId('505d3fb207a15601a9000000'), u'id': 2, u'name': u'w2'}>>>

5. 记录总数

>>> test.count()2>>>
