一、文件下载和解压

1)下载地址:http://www.alluxio.org/download

2) 解压命令如下:

$ wget http://alluxio.org/downloads/files/1.2.0/alluxio-1.2.0-bin.tar.gz
$ tar xvfz alluxio-1.2.0-bin.tar.gz
$ cd alluxio-1.2.0

 

二、 配置文件更改

目前只是基本配置更改:

1) /data/spark/software/alluxio-1.2.0/conf下的  alluxio-env.sh.template 复制一份为: alluxio-env.sh
更改如下:

# Copy it as alluxio-env.sh and edit that to configure Alluxio for your
# site. This file is sourced to launch Alluxio servers or use Alluxio shell
# commands.
#
# This file provides one way to configure Alluxio options by setting the
# following listed environment variables. Note that, setting this file will not
# affect jobs (e.g., Spark job or MapReduce job) that are using Alluxio client
# as a library. Alternatively, you can edit alluxio-site.properties file, where
# you can set all the configuration options supported by Alluxio
# (http://alluxio.org/documentation/) which is respected by both external jobs
# and Alluxio servers (or shell).
# The directory where Alluxio deployment is installed. (Default: the parent directory of libexec/).
export  ALLUXIO_HOME=/data/spark/software/alluxio-1.2.0
# The directory where log files are stored. (Default: ${ALLUXIO_HOME}/logs).
# ALLUXIO_LOGS_DIR
# Hostname of the master.
# ALLUXIO_MASTER_HOSTNAME
export ALLUXIO_MASTER_HOSTNAME=spark29
# This is now deprecated. Support will be removed in v2.0
# ALLUXIO_MASTER_ADDRESS
#export ALLUXIO_MASTER_ADDRESS=spark29
# The directory where a worker stores in-memory data. (Default: /mnt/ramdisk).
# E.g. On linux,  /mnt/ramdisk for ramdisk, /dev/shm for tmpFS; on MacOS, /Volumes/ramdisk for ramdisk
# ALLUXIO_RAM_FOLDER
export ALLUXIO_RAM_FOLDER=/data/spark/software/alluxio-1.2.0/ramdisk
# Address of the under filesystem address. (Default: ${ALLUXIO_HOME}/underFSStorage)
# E.g. "/my/local/path" to use local fs, "hdfs://localhost:9000/alluxio" to use a local hdfs
# ALLUXIO_UNDERFS_ADDRESS
export ALLUXIO_UNDERFS_ADDRESS=hdfs://spark29:9000
# How much memory to use per worker. (Default: 1GB)
# E.g. "1000MB", "2GB"
# ALLUXIO_WORKER_MEMORY_SIZE
export ALLUXIO_WORKER_MEMORY_SIZE=12GB
# Config properties set for Alluxio master, worker and shell. (Default: "")
# E.g. "-Dalluxio.master.port=39999"
# ALLUXIO_JAVA_OPTS
# Config properties set for Alluxio master daemon. (Default: "")
# E.g. "-Dalluxio.master.port=39999"
# ALLUXIO_MASTER_JAVA_OPTS
# Config properties set for Alluxio worker daemon. (Default: "")
# E.g. "-Dalluxio.worker.port=49999" to set worker port, "-Xms2048M -Xmx2048M" to limit the heap size of worker.
# ALLUXIO_WORKER_JAVA_OPTS
# Config properties set for Alluxio shell. (Default: "")
# E.g. "-Dalluxio.user.file.writetype.default=CACHE_THROUGH"
# ALLUXIO_USER_JAVA_OPTS

 

 
2)worker 下面的添加worker节点的地址
spark24
spark30
spark31
spark32
spark33

三 、主机配置更改

1)在家目录下更改 .bash_profile 添加一下内容:

export TACHYON_HOME=/data/spark/software/alluxio-1.2.0
PATH=$PATH:$HOME/bin:$HADOOP/bin:$JAVA_HOME/bin:$TACHYON_HOME/bin
2) 生效配置
 source .bash_profile

四 、Spark 添加依赖Jar

1、在所有的spark主机的spark安装目录下的conf目录下

   更改spark-env.sh 后面添加:export SPARK_CLASSPATH="/data/spark/software/spark-1.5.2-bin-hadoop2.6/lib/alluxio-core-client-spark-1.2.0-jar-with-dependencies.jar:$SPARK_CLASSPATH"

五 、分发到各个Worker节点上去

1、alluxio 软件:scp -r ./alluxio-1.2.0 spark30:/data/spark/software/

六、格式化和启动

1、进入到alluxio的安装目录下面的bin目录,执行命令: alluxio format  进行内存格式化。

2、启动集群:./alluxio-start.sh all

 

七、可能遇到问题

1、启动worker报错,报错内容:Pseudo-terminal will not be allocated because stdin is not a terminal.

更改:alluxio\bin\alluxio-workers.sh  的44行内容

原始内容为:

nohup ssh -o ConnectTimeout=5 -o StrictHostKeyChecking=no -t ${worker} ${LAUNCHER} \ 

改成如下:
nohup ssh -o ConnectTimeout=5 -o StrictHostKeyChecking=no -tt  $ {worker}  ${LAUNCHER} \

 

2、如果启动报sudo相关命令错误,是因为启动用户未在sudoers里面,需要将用户添加到此文件中,添加方法搜下root位置,再后面添加即可。

内容如下:

root ALL=(ALL) ALL
spark ALL=(ALL) ALL

同时把此文件中的:#Defaults    requiretty 注释掉。

3、如果还报错,可以在启动master之后,一个一个节点去启动worker。

 

八、 官网安装说明

官网安装说明:http://www.alluxio.org/docs/master/cn/Running-Alluxio-on-a-Cluster.html  有中文的,可以看看。
