这篇文章给大家介绍怎么在Centos 6.3系统中安装卡桑德拉数据库，内容非常详细，感兴趣的小伙伴们可以参考借鉴，希望对大家能有所帮助。
1 下载Java jdk:
下载完成后，解压jdk:
塔尔-兹夫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/JDK 1。7 .0 _ 17
PATH=$JAVA_HOME/bin:$PATH
类路径=。美元JAVA _ HOME/lib/dt。jar : $ JAVA _ HOME/lib/tools。坛子
exportJAVA_HOME
exportPATH
exportCLASSPATHPS:只需将JAVA_HOME的路径改一下即可，改成刚才解压后爪哇开发工具包的目录目录即可，我的是把爪哇开发工具包压缩包放在/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 '
四上面的步骤执行完成后，执行下如下命令
来源/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
爪哇版本
我这里执行后，会输出如下内容：
[root @ localhost ~]# Java-版本
jav rehow ' 1。7 .0 _ 17 '
Java TM Seruntimeenvironment(build 1。7 .0 _ 17-b02)
javaHotsPot(TM)ClientVM(构建23.7-b01，混合模式)
[root @ localhost ~]#说明jdk安装成功，这里的版本是1.7
支持爪哇开发工具包的安装到此结束，下一步是cassandra的安装
一下载卡珊德拉：
地址：http://www.apache.org/dyn/closer.cgi？path=/Cassandra/1。2 .4/Apache-Cassandra-1。2 .4-src。焦油。地面零点
我这里用的版本是：Apache-Cassandra-1。2 .4-bin。焦油。地面零点
2下载完成后，直接解压：
塔尔-兹夫apache-cassandra-1.2.4-bin.tar.gz
解压完成后，得到如下目录：apache-cassandra-1.2.4
进入该目录下的垃圾桶目录，直接启动卡桑德拉即可：
cd apache-cassandra-1.2.4/bin。/Cassandra-f[启动卡珊德拉】
启动后，会输出一大堆的代码，如下，表明卡桑德拉启动成功：
[root@localhostbin]# ./cassandra
