1.安裝jdk,配置環境變量node
下載地址:http://yunpan.cn/csUMbjpYd6LIU 提取碼 8e1dssh
修改/etc/profileide
export JAVA_HOME=/opt/jdk1.6.0_12oop
export PATH=$PATH:$JAVA_HOME/binthis
重啓spa
2.下載hadoop1.1.2orm
下載地址:http://yunpan.cn/csUMinfxTYFZr 提取碼 7bf8xml
修改配置文件hadoop
hadoop-env.shci
export JAVA_HOME=/opt/jdk1.6.0_12 |
core-site.xml
<?xml version="1.0"?> <?xml-stylesheet type="text/xsl" href="configuration.xsl"?> <!-- Put site-specific property overrides in this file. --> <configuration> <property> <name>fs.default.name</name> <value>hdfs://localhost:9000</value> </property> <property> <name>hadoop.tmp.dir</name> <value>/opt/hadoop-1.1.2/tmp</value> </property> </configuration> |
hdfs-site.xml
<?xml version="1.0"?> <?xml-stylesheet type="text/xsl" href="configuration.xsl"?> <!-- Put site-specific property overrides in this file. --> <configuration> <!-- 設置備份的份數 --> <property> <name>dfs.replication</name> <value>1</value> </property> </configuration> |
mapred-site.xml
<?xml version="1.0"?> <?xml-stylesheet type="text/xsl" href="configuration.xsl"?> <!-- Put site-specific property overrides in this file. --> <configuration> <property> <name>mapred.job.tracker</name> <value>localhost:9001</value> </property> </configuration> |
免密碼登錄
$ ssh-keygen -t rsa $ cd $HOME/.ssh $ cp id_rsa.pub authorized_keys $ ssh localhost |
格式化HDFS:hadoop namenode -format
啓動hadoop羣集:start-all.sh
卸載hadoop,因爲沒配環境變量,直接刪除文件就行
