如何在Windows上启动Cassandra？ 我的环境看起来像什么？
我在Windows上启动Cassandra时遇到错误... uname -o不受支持。 我正在使用uname（GNU sh-utils）2.0 我不是在cygwin中运行，而只是一个纯粹的PowerShell窗口。
我的Cassandra版本直接来自git
以下是我的尝试：
D:\dev\3rdparty\cassandra\cassandra [trunk +1 ~0 -0 !]> .\bin\cassandra.bat -v -f
Detected powershell execution permissions. Running with enhanced startup scripts.

Error occurred during initialization of VM
Could not reserve enough space for object heap

Error: A fatal exception has occurred. Program will exit.
答案 0 :(得分：0)
可能是你没有正确设置环境变量..
你必须在用户变量下的环境变量中设置cassandra_home直到低于点。
CASSANDRA_HOME : D:\dev\3rdparty\cassandra\cassandra
- ＆GT;第二件事是错误的建议
-Xms3072M -Xmx3072M这是更多
Xms应该是1 gb左右，或者Xmx和Xmx的一半应该是RAM大小的1/2。
所以根据你系统的ram将这两件事改成cassandra / conf下的cassandra-env.sh文件
