為了安全起見(jiàn)，建議直接上Java 1.7版本的jdk，因?yàn)镃assandra是運(yùn)行于JDK之上，所以JDK是必須要安裝的。不要試圖用java jdk 1.6 版本，結(jié)果會(huì)讓你搞了好長(zhǎng)時(shí)間都不行。

-----------------------------------------------------------------------------------------

1> 下載Java jdk:

     下載地址：http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase7-521261.html

     我這里用的是：jdk-7u17-linux-i586.tar.gz

     PS：這個(gè)是需要登錄才能下載的，所以建議注冊(cè)后，登錄進(jìn)去先下載到本地，然后再?gòu)谋镜赜?jì)算機(jī)傳到VM上去。

2> 下載完成后，解壓jdk：

      tar -zxvf jdk-7u17-linux-i586.tar.gz

3> 解壓完成后，配置環(huán)境變量：

     vim /etc/profile

     在打開(kāi)的文件的末尾，增加如下代碼：

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：只需將JAVA_HOME的路徑改一下即可，改成剛才解壓后jdk的目錄目錄即可，我的是把jdk壓縮包放在/usr/local目錄下了，然后直接

在這里解壓的，所以解壓后的包也就直接在該目錄下了【jdk1.7.0_17】,所以我這里JAVA_HOME的路徑為 "/usl/local/jdk1.7.0_17"

4> 上面的步驟執(zhí)行完成后，執(zhí)行下如下命令

     source /etc/profile

     或者重啟下linux ，配置才可生效

5> 執(zhí)行完上面的步驟，下一步就是看一下java jdk是否安裝成功，執(zhí)行下如下命令

     java -version

     我這里執(zhí)行后，會(huì)輸出如下內(nèi)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 ~]#

說(shuō)明jdk安裝成功，這里的版本是1.7

支持jdk的安裝到此結(jié)束，下一步是cassandra的安裝

1> 下載Cassandra：

     地址：http://www.apache.org/dyn/closer.cgi?path=/cassandra/1.2.4/apache-cassandra-1.2.4-src.tar.gz

     我這里用的版本是：apache-cassandra-1.2.4-bin.tar.gz

2> 下載完成后，直接解壓：

      tar -zxvf apache-cassandra-1.2.4-bin.tar.gz

      解壓完成后，得到如下目錄：apache-cassandra-1.2.4

      進(jìn)入該目錄下的bin目錄，直接啟動(dòng)Cassandra即可：

      cd apache-cassandra-1.2.4/bin

      ./cassandra -f 【啟動(dòng)cassandra】

      啟動(dòng)后，會(huì)輸出一大堆的代碼，如下，表明Cassandra啟動(dòng)成功：
