1. 安装
这里以安装hadoop-0.20.2为例
先安装java,参考这个
去着下载hadoop
解压
tar -xzf hadoop-0.20.2
2. 配置
修改环境变量
vim ~/.bashrc export HADOOP_HOME=/home/rte/hadoop-0.20.2 #这里为实际hadoop解压的目录位置 export PATH=$PATH:$HADOOP_HOME/bin source ~/.bashrc
配置hadoop-env.sh
vim conf/hadoop-env.sh export JAVA_HOME=/home/rte/Software/java/jdk1.6.0_27
配置conf/core-site.xml、conf/hdfs-site.xml、conf/mapred-site.xml文件
文件：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> </configuration>
文件：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>
文件：hdfs-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>dfs.replication</name> <value>2</value> </property> </configuration>
3. 开启关闭
通过NameNode格式化HDFS文件系统
cd hadoop-0.20.2/conf hadoop namenode -format
开启hadoop
cd hadoop-0.20.2/bin sh start-all.sh
通过jps命令检查期望的hadoop进程是否运行
关闭hadoop
cd hadoop-0.20.2/bin sh stop-all.sh
