需求:使用Python操控ZooKeeper

1.由于python客户端依赖c的客户端所以要先安装c版本的客户端
cd zookeeper-3.4.5/src/c
./configure
make
make install

2.测试c版本客户端,需要gcc和python-devel
./cli_mt localhost:2181
Watcher SESSION_EVENT state = CONNECTED_STATE
Got a new session id: 0x23f9d77d3fe0001

ls /
time = 0 msec
/: rc = 0
consumers
storm
brokers
zookeeper
jobkeeper
time = 0 msec

这样就安装成功了

3.下载python扩展包，并且解压：
地址:https://pypi.python.org/pypi/zkpython/0.4.2

4.如果找不到Pyhon.h，可能由于没有安装python26-devel
32位直接运行
yum install python26-devel.i386

5.测试是否成功

import zookeeper

如果报错:
>>> import zookeeper
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: libzookeeper_mt.so.2: cannot open shared object file: No such file or directory

在shell中配置或者假如/etc/profile文件中:
export LD_LIBRARY_PATH=/usr/local/lib/

6.使用
>>> import zookeeper
>>> hander = zookeeper.init("dc002.tj:2181")
>>> dir(zookeeper) #方法列表

#测试get命令
>>> zookeeper.get(hander,"/jobkeeper/gamedc/job/kpi-day-pay_day")
(‘{"dependency":[{"name":"etl-day-pay_log","type":"day"}],"name":"kpi-day-pay_day","owner":"dc","path":"${SCRIPTS_HOME}/kpi/pay/pay_day.sh","type":"day","hour":"01"}‘, {‘pzxid‘: 4298844949L, ‘ctime‘: 1411896174285L, ‘aversion‘: 0, ‘mzxid‘: 4299652800L, ‘numChildren‘: 0, ‘ephemeralOwner‘: 0L, ‘version‘: 2, ‘dataLength‘: 163, ‘mtime‘: 1412055214425L, ‘cversion‘: 0, ‘czxid‘: 4298844949L})

#其他的delete,set可以自己测试了,都是api
