Hadoop安装之standAlone单机

hadoop安装1.x和2.x有三种安装架构，本文将介绍第一种安装模式standAlone

一：standAlone(单机)

standAlone安装将所有服务都安装在一台机器上，如下：

运行服务	服务器IP
NameNode	192.168.254.100
SecondaryNameNode	192.168.254.100
DataNode	192.168.254.100
ResourceManager	192.168.254.100
NodeManager	192.168.254.100

1）下载安装：

JDK的安装请自行安装。

下载地址：http://archive.apache.org/dist/hadoop/common/hadoop-2.7.5/hadoop-2.7.5.tar.gz

解压：

mkdir -p /export/softwares

mkdir -p /exprot/servers

cd /export/softwares

tar -zxvf hadoop-2.7.5.tar.gz -C ../servers/

2）修改配置文件：

2.1：修改core-site.xml

cd /export/servers/hadoop-2.7.5/etc/hadoop

vim core-site.xml

<configuration>

<property>

<name>fs.default.name</name>



<value>hdfs://192.168.254.100:8020</value>

</property>

<property>

<name>hadoop.tmp.dir</name>

<value>/export/servers/hadoop-2.7.5/hadoopDatas/tempDatas</value>

</property>



<property>

<name>io.file.buffer.size</name>

<value>4096</value>

</property>



<property>

<name>fs.trash.interval</name>

<value>10080</value>

</property>

</configuration>

2.2：修改hdfs-site.xml

cd /export/servers/hadoop-2.7.5/etc/hadoop

vim hdfs-site.xml

<configuration>





<property>

<name>dfs.namenode.secondary.http-address</name>

<value>node01:50090</value>

</property>

<property>



<name>dfs.namenode.http-address</name>

<value>node01:50070</value>

</property>

<property>

<name>dfs.namenode.name.dir</name>

<value>file:///export/servers/hadoop-2.7.5/hadoopDatas/namenodeDatas,file:///export/servers/hadoop-2.7.5/hadoopDatas/namenodeDatas2</value>

</property>



<property>

<name>dfs.datanode.data.dir</name>

<value>file:///export/servers/hadoop-2.7.5/hadoopDatas/datanodeDatas,file:///export/servers/hadoop-2.7.5/hadoopDatas/datanodeDatas2</value>

</property>

<property>

<name>dfs.namenode.edits.dir</name>

<value>file:///export/servers/hadoop-2.7.5/hadoopDatas/nn/edits</value>

</property>

<property>

<name>dfs.namenode.checkpoint.dir</name>

<value>file:///export/servers/hadoop-2.7.5/hadoopDatas/snn/name</value>

</property>

<property>

<name>dfs.namenode.checkpoint.edits.dir</name>

<value>file:///export/servers/hadoop-2.7.5/hadoopDatas/dfs/snn/edits</value>

</property>



<property>

<name>dfs.replication</name>

<value>3</value>

</property>



<property>

<name>dfs.permissions</name>

<value>false</value>
