Cassandra单节点安装 [英] Cassandra single node installation

问题描述

我只是尝试在我的 ubuntu：12.04 上安装 cassandra 我已经遵循的步骤

I just try to install cassandra on my ubuntu:12.04. Steps i have followed

  Installed java version 1.7.XX and verified with java -version
  apt-get install libjna-java  //Installs jna
  python 2.7 is installed already

  Extracted to /usr/local/installables/
  Successfully extracted.

  Then I set cassandra home

  export CASSANDRA_HOME=/usr/local/installables/dse-2.2.2/resources/cassandra
  export PATH=$PATH:$CASSANDRA_HOME/bin

pscenter.tar.gz dse.tar.gz

pscenter.tar.gz dse.tar.gz

  I created /var/cassandra/saved_caches, /var/cassandra/data, /var/cassandra/commitlog

  I updated cassandra-env.sh -Xss 280 from 180

  I left listen_address as empty, rpc_address as 0.0.0.0 and seed ip as 127.0.0.1 

  I left jmx port as 7199. I left all the default config in cassandra.yaml

现在我试图运行cassandra

Now i tried to run cassandra

  /usr/local/installbles/dse/cassandra/bin/cassandra

它说

  xss =  -ea -javaagent:/usr/local/installables/dse-2.2.2/resources/cassandra/lib/jamm-0.2.5.jar -XX:+UseThreadPriorities -XX:ThreadPriorityPolicy=42 -Xms1954M -Xmx1954M -Xmn200M -XX:+HeapDumpOnOutOfMemoryError -Xss280k
 Error: Could not find or load main class com.datastax.bdp.server.DseDaemon

我错过了一些安装配置步骤的dse。请让我知道错误和任何链接以设置单节点cassandra设置。

So I can understand i missed some installation config steps of dse. Please let me know whats the error and any links to set up single node cassandra setup.

推荐答案

您使用错误的命令启动它。如果你安装了dse，那么命令将是：

You are using the wrong command to start it. If you have dse installed then the command would be:

<path to dse bin>/dse cassandra

这将启动dse在后台运行。如果您要在前台运行它，则：

This will start dse running in the background. If you want to run it in the foreground then:

<path to dse bin>/dse cassandra -f
