Shell脚本之——Hadoop3单机版安装

1.解压

tar -zxf /opt/install/hadoop-3.1.3.tar.gz -C /opt/soft/

2.文件重命名

mv /opt/soft/hadoop-3.1.3 /opt/soft/hadoop313

3.配置环境变量

  sed -i '73a\export HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop' /etc/profile
  sed -i '73a\export HADOOP_LIBEXEC_DIR=$HADOOP_HOME/libexec' /etc/profile
