原创 Linux操作系统 作者:redhouser 时间:2012-05-31 14:26:13 0 删除 编辑

擦作系统版本:
[root@rhel5 lib]# uname -a
Linux rhel5 2.6.18-8.el5xen #1 SMP Thu Mar 15 21:02:53 EDT 2007 i686 i686 i386 GNU/Linux

1环境准备
1.1用户准备
--logon as root
mkdir -p /nosql/cassandra

groupadd nosqlg
useradd nosql -g nosqlg

chown -R nosql:nosqlg /nosql/cassandra
chmod -R 755 /nosql/cassandra

passwd nosql

1.2 java准备
使用java version "1.6.0_06" 时报错,参见附录1。

www.java.com上下载jre1.7:
以nosql用户ftp到/nosql/cassandra
tar -zxvf jre-7u4-linux-i586[1].tar.gz

1.3 修改用户profile
vi .bash_profile
-----------add following lines
JAVA_HOME=/nosql/cassandra/jre1.7.0_04
export JAVA_HOME

PATH=$JAVA_HOME/bin:$PATH:$HOME/bin
export PATH
------------

. ./.bash_profile

[nosql@rhel5 bin]$ java -version
java version "1.7.0_04"
Java(TM) SE Runtime Environment (build 1.7.0_04-b20)                                                                                
Java HotSpot(TM) Server VM (build 23.0-b21, mixed mode)

2软件安装、配置
2.1下载软件
http://cassandra.apache.org/download/下载apache-cassandra-1.0.10-bin.tar.gz

2.2ftp
以nosql用户ftp到/nosql/cassandra

2.3解压文件
--logon as nosql:

2.4.1配置cassandra.yaml
[nosql@rhel5 conf]$vi cassandra.yaml
----------------------------------------------------------
# directories where Cassandra should store data on disk.
data_file_directories:
    - /nosql/cassandra/data

# commit log
commitlog_directory: /nosql/cassandra/commitlog

# saved caches
saved_caches_directory: /nosql/cassandra/saved_caches

cluster_name: 'MyCluster'

# TCP port, for commands and data
storage_port: 7000

# port for Thrift to listen for clients on
rpc_port: 9160
----------------------------------------------------------

说明:设置initial_token:0报错,保留空即可,参见附录2。

2.4.2配置log4j-server.properties
[nosql@rhel5 conf]$ vi log4j-server.properties
----------------------------------------------------------
# Edit the next line to point to your logs directory
log4j.appender.R.File=/nosql/cassandra/system.log
----------------------------------------------------------

2.4.3配置cassandra-env.sh
[nosql@rhel5 conf]$ vi cassandra-env.sh
MAX_HEAP_SIZE根据系统物理内存设置;HEAP_NEWSIZE设置为MAX_HEAP_SIZE/4;这两个参数会自动设置,可以去掉注释指定具体值.
----------------------------------------------------------
MAX_HEAP_SIZE="400M"
HEAP_NEWSIZE="100M"
