环境要求：java、ssh
1.上传并解压tar包
[root@hadoop000 software]# rz #上传hadoop-2.8.1.tar.gz [root@hadoop000 software]# tar -xzvf hadoop-2.8.1.tar.gz
2.配置环境变量
[root@hadoop000 software]# vi /etc/profile export HADOOP_HOME=/opt/software/hadoop-2.8.1 export PATH=$HADOOP_HOME/bin:$PROTOC_HOME/bin:$FINDBUGS_HOME/bin:$MAVEN_HOME/bin:$JAVA_HOME/bin:$PATH [root@hadoop000 software]# source /etc/profile
3.配置文件
[hadoop@hadoop000 ~]# cd /opt/software/hadoop-2.8.1 [hadoop@hadoop000 hadoop-2.8.1]# vi etc/hadoop/core-site.xml <configuration> <property> <name>fs.defaultFS</name> <value>hdfs://192.168.137.130:9000</value> # 配置自己机器的IP </property> </configuration> [hadoop@hadoop000 hadoop-2.8.1]# vi etc/hadoop/hdfs-site.xml <configuration> <property> <name>dfs.replication</name> <value>1</value> </property> </configuration> #更改JAVA_HOME [hadoop@hadoop000 hadoop-2.8.1]# vi etc/hadoop/hadoop-env.sh # 将export JAVA_HOME=${JAVA_HOME}改为 export JAVA_HOME=/usr/java/jdk1.8.0_45
4.格式化和启动
[hadoop@hadoop000 hadoop-2.8.1]# bin/hdfs namenode -format [hadoop@hadoop000 hadoop-2.8.1]# sbin/start-dfs.sh
5.检查是否成功
[hadoop@hadoop000 hadoop-2.8.1]# jps 19536 DataNode 19440 NameNode 19876 Jps 19740 SecondaryNameNode 访问： http://localhost:50070
