linux安装Cassandra数据库
为了安全起见，建议直接上Java 1.7版本的jdk，因为Cassandra是运行于JDK之上，所以JDK是必须要安装的。
开始我是用的java jdk 1.6 版本的，结果搞了好长时间都不行，最后换成1.7版本的后，就OK了。
-----------------------------------------------------------------------------------------
1> 下载Java jdk:
下载地址： http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase7-521261.html
我这里用的是： jdk-7u17-linux-i586.tar.gz
PS：这个是需要登录才能下载的，所以建议注册后，登录进去先下载到本地，然后再从本地计算机传到VM上去。
2> 下载完成后，解压jdk：
tar -zxvf jdk-7u17-linux-i586.tar.gz
3> 解压完成后，配置环境变量：
vim /etc/profile
在打开的文件的末尾，增加如下代码：
JAVA_HOME=/usr/local/jdk1. 7 .0_17 PATH =$JAVA_HOME/ bin:$PATH CLASSPATH =.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/ tools.jar export JAVA_HOME export PATH export CLASSPATH
PS：只需将JAVA_HOME的路径改一下即可，改成刚才解压后jdk的目录目录即可，我的是把jdk压缩包放在/usr/local目录下了，然后直接
在这里解压的，所以解压后的包也就直接在该目录下了【jdk1.7.0_17】,所以我这里JAVA_HOME的路径为 "/usl/local/jdk1.7.0_17"
4> 上面的步骤执行完成后，执行下如下命令
source /etc/profile
或者重启下linux ，配置才可生效
5> 执行完上面的步骤，下一步就是看一下java jdk是否安装成功，执行下如下命令
java -version
我这里执行后，会输出如下内容：
[root@localhost ~]# java - version java version " 1.7.0_17 " Java(TM) SE Runtime Environment (build 1.7 .0_17- b02) Java HotSpot(TM) Client VM (build 23.7 - b01, mixed mode) [root@localhost ~]#
支持jdk的安装到此结束，下一步是cassandra的安装
==================================================================
1> 下载Cassandra：
地址： http://www.apache.org/dyn/closer.cgi?path=/cassandra/1.2.4/apache-cassandra-1.2.4-src.tar.gz
我这里用的版本是：apache-cassandra-1.2.4-bin.tar.gz
2> 下载完成后，直接解压：
tar -zxvf apache-cassandra-1.2.4-bin.tar.gz
进入该目录下的bin目录，直接启动Cassandra即可：
cd apache-cassandra-1.2.4/bin
./cassandra -f 【启动cassandra】
启动后，会输出一大堆的代码，如下，表明Cassandra启动成功：
