Adr*_*ian 1 cluster-computing cassandra windows-7-x64 opscenter cassandra-2.2
我正在寻找一组指令来在Window 7 64位PC上创建本地多节点Cassandra 2.x集群.
它最好使用CCM"Cassandra Cluster Manager"并允许使用DataStax OpsCenter进行管理
我按照" 轻松实现Windows上的Apache Cassandra入门 "中的说明进行操作,但它们适用于单节点群集.
编辑:我坚持使用CCM在每个节点上部署OpsCenter代理,任何想法?

先决条件:
假设已经安装了以下工具:
第1步:安装Python
从这里下载并安装最新版本的Python 2.x, 例如https://www.python.org/ftp/python/2.7.11/python-2.7.11.amd64.msi
注意:这也将安装" pip "工具
需要将以下目录添加到PATH中
<PYTHON_INSTALL_DIR>\Python
<PYTHON_INSTALL_DIR>\Python\Scripts
<ANT_INSTALL_DIR>\bin

第2步:安装CCM"Cassandra Cluster Manager"
在新的命令提示符/ Powershell窗口中(以您自己的身份登录)
键入"pip install ccm" - 将自动下载并安装ccm
> pip install ccm
Collecting ccm
Downloading ccm-2.0.6.tar.gz (56kB)

第3步:安装"psutil(python系统和进程实用程序)"
在与步骤2相同的窗口中:
键入"pip install psutil" - - 将自动下载并安装psutil
> pip install psutil
Collecting psutil
Downloading psutil-3.3.0-cp27-none-win_amd64.whl (92kB)

步骤4:Set-ExecutionPolicy Unrestricted 在新的Powershell窗口(以本地管理员身份登录)中,键入"Set-ExecutionPolicy Unrestricted"
*注意:您必须设置Windows Powershell的执行策略以允许CCM启动Cassandra的实例.不受限制的执行策略还允许CCM在常规命令提示符(cmd)以及Windows Powershell上运行
PS C:\Windows\system32> Set-ExecutionPolicy Unrestricted
Execution Policy Change
The execution policy helps protect you from scripts that you do not trust. Changing the execution policy might expose
you to the security risks described in the about_Execution_Policies help topic. Do you want to change the execution
policy?

第5步:注册PY扩展
注意:将.PY扩展名添加到环境变量$ PATHEXT,以允许从任何位置执行ccm(以管理员身份在PowerShell上运行):
在与步骤4类型相同的窗口中
[Environment]::SetEnvironmentVariable("PATHEXT", "$env:PATHEXT;.PY", "MACHINE")

步骤6:检查CCM是否已启动并正在运行
在新的命令提示符窗口(以您自己登录)中键入:
>ccm status
No currently active cluster (use ccm cluster switch)

第7步:更新主机文件
以管理员身份打开记事本,并将以下行打开到C:\ Windows\System32\drivers\etc\hosts文件:
#cassandra nodes
127.0.0.1 127.0.0.2
127.0.0.1 127.0.0.3
127.0.0.1 127.0.0.4
127.0.0.1 127.0.0.5
127.0.0.1 127.0.0.6

步骤8:使用Cassandra v2.1.2创建并填充3节点集群
注意:这将下载Cassandra的2.1.2版本,构建它然后用它来创建一个名为"mytestcluster"的新CCM集群.
C:\Users\myusername>ccm create mytestcluster -v 2.1.2
