进入/opt 把文件拖进去 cd /opt
解压 tar -zxvf hadoop-2.6.0-cdh5.14.2.tar.gz
配置环境： vi /etc/profile 在末行输入
export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE HISTCONTROL export JAVA_HOME=/opt/jdk1.8.0_221 export CLSASSPATH=.:$JAVA_HOME/lib/rt.jar:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar export HADOOP_HOME=/opt/hadoop export HADOOP_MAPRED_HOME=$HADOOP_HOME export HADOOP_COMMON_HOME=$HADOOP_HOME export HADOOP_HDFS_HOME=$HADOOP_HOME export YARN_HOME=$HADOOP_HOME export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native export HADOOP_INSTALL=$HADOOP_HOME export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$PATH将hadoop-2.6.0-cdh5.14.2改成 hadoop
检查是否成功 source /etc/profile hadoop version
进hadoop里面的hadoop
进 hadoop-env.sh里面
进入 vi core-site.xml

输入 ssh 主机名 查看书否成功 成功则exit退出
格式化 hadoop namenode -format 开启 start-all.sh 关闭stop-all.sh检测开起 后 输入 jps 查看进程 在网页导航栏输入ip:9000
