一、配置系统环境

1.清除默认防火墙规则

# service iptables save
iptables：将防火墙规则保存到 /etc/sysconfig/iptables：     [确定]

2.关闭Selinux

# cat /etc/sysconfig/selinux |grep SELINUX|grep -v ^#
SELINUX=disabled 
SELINUXTYPE=targeted 
#

3.配置ip地址

# cat
/etc/sysconfig/network-scripts/ifcfg-eth0 |grep IPADDR
IPADDR=192.168.1.1
#

4.配置主机名

# cat /etc/sysconfig/network|grep HOSTNAME
HOSTNAME=node1
#

5.配置hosts

# cat /etc/hosts |tail -n 1
192.168.1.1    node1
#

6.时间同步

# ntpdate 192.168.1.254

7.本机ssh免密码登录

# ssh-keygen -t rsa -f ~/.ssh/id_rsa  -P ‘‘
# ssh-copy-id -i node1
The authenticity of host ‘node1 (::1)‘can‘t be established.
RSA key fingerprint is23:2a:43:2d:a7:81:a3:56:a4:a8:65:35:03:8b:05:8b.
Are you sure you want to continueconnecting (yes/no)? yes
Warning: Permanently added ‘node1‘ (RSA) tothe list of known hosts.
root@node1‘s password: 
Now try logging into the machine, with"ssh ‘node1‘", and check in:
 
 .ssh/authorized_keys
 
to make sure we haven‘t added extra keysthat you weren‘t expecting.
 
#

二、配置JAVA环境

1.安装JDK

# rpm -ivh jdk-7-linux-x64.rpm

2.配置JAVA环境变量

# cat /etc/profile.d/java.sh
JAVA_HOME=/usr/java/default
PATH=$JAVA_HOME/bin:$PATH
# source /etc/profile.d/java.sh

3.测试JAVA环境

# java -version
java version "1.7.0_09-icedtea"
OpenJDK Runtime Environment
(rhel-2.3.4.1.el6_3-x86_64)
OpenJDK 64-Bit Server VM (build 23.2-b09,
mixed mode)
#

三、本地模式安装Tachyon

1.下载并解压Tachyon

# wgethttp://tachyon-project.org/downloads/tachyon-0.5.0-bin.tar.gz
# tar -zxf tachyon-0.5.0-bin.tar.gz  -C /usr/local/
# ln -s /usr/local/tachyon-0.5.0//usr/local/tachyon

2.配置Tachyon环境变量

# cat /etc/profile.d/tachyon.sh
TACHYON_HOME=/usr/local/tachyon
PATH=$TACHYON_HOME/bin:$PATH
# source /etc/profile.d/tachyon.sh

3.复制tachyon配置文件

# pwd
/usr/local/tachyon/conf
# cp tachyon-env.sh.template tachyon-env.sh

4.配置tachyon

# cat tachyon-env.sh |egrep ‘JAVA_HOME|TACHYON_MASTER_ADDRESS|TACHYON_UNDERFS_ADDRESS|TACHYON_WORKER_MEMORY_SIZE‘|grep-v ^#|grep -v ^‘ ‘
JAVA_HOME=/usr/java/default
export JAVA="$JAVA_HOME/bin/java"
export TACHYON_MASTER_ADDRESS=node1
export TACHYON_UNDERFS_ADDRESS=$TACHYON_HOME/underfs
export TACHYON_WORKER_MEMORY_SIZE=512MB
#

5．配置slaves

# pwd
/usr/local/tachyon/conf
# cat slaves |grep -v ^#
node1
#

6.初始化文件系统

# tachyon format
Connection to node1... Formatting Tachyon
Worker @ localhost.localdomain
Removing local data under folder:
/mnt/ramdisk/tachyonworker/
Connection to node1 closed.
Formatting Tachyon Master @ node1
Formatting JOURNAL_FOLDER:
/usr/local/tachyon-0.5.0/libexec/../journal/
Formatting UNDERFS_DATA_FOLDER:
/usr/local/tachyon-0.5.0/libexec/../underfs/tmp/tachyon/data
Formatting UNDERFS_WORKERS_FOLDER:
/usr/local/tachyon-0.5.0/libexec/../underfs/tmp/tachyon/workers
#

7.启动tachyon的local模式

# tachyon-start.sh local
Killed 0 processes
Killed 0 processes
Connection to node1... Killed 0 processes
Connection to node1 closed.
Formatting RamFS: /mnt/ramdisk (512mb)
Starting master @ node1
Starting worker @ localhost.localdomain
#

8.查看tachyon进程

# jps
33403 TachyonWorker
33782 Jps
33367 TachyonMaster
#

9.测试tachyon

# tachyon runTest Basic CACHE_THROUGH

10.停止tachyon

 # tachyon-stop.sh 
Killed 1 processes
Killed 1 processes
Connection to node1... Killed 0 processes
Connection to node1 closed.
