我打算为 Zookeeper 使用 Python kazoo 库。这完全是关于 Python 的问题,而不是 zookeeper 我想这意味着如何正确使用 Python kazoo..
我对 python 完全陌生,所以我不知道如何开始以及如何使用 kazoo 连接 zookeeper。
这是我正在阅读的文档,以开始将 kazoo 用于 Zookeeper。
http://kazoo.readthedocs.org/en/latest/install.html
在那个 wiki 中,他们要求安装 kazoo。他们为此使用了一些 pip 命令?
pip 在这里做什么?我目前正在使用 Windows,所以我安装了 cygwin 和 python。我正在使用 Python 2.7.3
host@D-SJC-00542612 ~
$ python
Python 2.7.3 (default, Dec 18 2012, 13:50:09)
[GCC 4.5.3] on cygwin
现在我所做的是 - 我从上面的网站完全复制了这个命令 - pip install kazoo
并在我的 cygwin 命令提示符下运行它。
host@D-SJC-00542612 ~
$ pip install kazoo

Cleaning up...
是否安装正确?现在我可以开始用 python 编写代码来连接 zookeeper 了吗?
很抱歉问了所有这些愚蠢的问题,因为我没有任何 python 背景,所以在这里学习一点......
我猜这里全是关于 Python 的问题,而不是 zookeeper..
最佳答案
pip
是安装包的常用方法。它从 pypi 查询并下载包.
Kazoo 已根据日志语句安装。试试看。
你应该能够在 where python is installed\lib\site-packages\kazoo
找到这个包。
您应该尝试无错误地加载(导入)包:
from kazoo.client import KazooClient
启动动物园管理员之后。您的 zookeeper 配置将包含客户端端口详细信息。
tickTime=2000
dataDir=...../zookeeperdata/cluster/server1/data
clientPort=2181
initLimit=5
使用它来连接到 zookeeper。
# Create a client and start it
zk = KazooClient(hosts='127.0.0.1:2181')
zk.start()
# Now you can do the regular zookepper API calls
# Ensure some paths are created required by your application
zk.ensure_path("/app/someservice")
# In the end, stop it
zk.stop()
