Centos 6.3安装Cassandra数据库经验分享

1> 下载Java jdk:

下载地址:http://www.jb51.net/softs/75615.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:

[[email protected] ~]# 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) [[email protected] ~]#

说明jdk安装成功,这里的版本是1.7

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

解压完成后,得到如下目录:apache-cassandra-1.2.4

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:
