系統(tǒng)：centos 6.10
jdk：jdk-8u281-linux-x64.tar.gz
hadoop: hadoop-2.10.1.tar.gz

1翅萤、jdk和hadoop安裝包復制解壓到服務器着倾，配置環(huán)境變量
cd /root
vim .bashrc
export JAVA_HOME=/root/hd/jdk1.8.0_281
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH
export HADOOP_HOME=/root/hd/hadoop-2.10.1
export PATH=$HADOOP_HOME/bin:$PATH

修改完環(huán)境變量執(zhí)行：
source .bashrc使用命令查看是否配置OK：
java -version其爵，hadoop version2姑子、修改Hadoop配置文件
cd /root/hd/hadoop-2.10.1/etc/hadoop

2.1、
vim core-site.xml
<configuration>
<property>
<name>fs.defaultFS</name>
<value>hdfs://192.168.2.11:9000</value>
</property>
<property>
<name>hadoop.tmp.dir</name>
<value>/root/hd/hadoop-2.10.1/tmp</value>
</property>
<property>
<name>hadoop.native.lib</name>
<value>false</value>
<description>Should native hadoop libraries, if present, be used.</description>
</property>
</configuration>

3恨锚、啟動Hadoop
3.1宇驾、格式化hadoop文件
cd /root/hd/hadoop-2.10.1/sbin倍靡，hadoop namenode -format
image.png
3.2猴伶、啟動服務
./start-all.sh，中途會讓輸幾次密碼3.3塌西、查看服務是否啟動
