标签：nbsp hadoop1 datanode 接下来 火墙 selinux man name key
首先创建4台虚拟机，规划如下
| IP地址 | 主机名 | 安装软件 | 运行服务 |
| 192.168.16.134 | hadoop1 | jdk,hadoop | namenode,Journalnode,ZKFC,Resourcemanager |
| 192.168.16.135 | hadoop2 | jdk,hadoop,zookeeper | namenode,datanode,Journalnode,ZKFC,Resourcemanager,zookeeper |
| 192.168.16.136 | hadoop3 | jdk,hadoop,zookeeper | namenode,datanode,Journalnode,zookeeper |
| 192.168.16.137 | hadoop4 | jdk,hadoop,zookeeper | namenode,datanode,zookeeper |
接下来关闭防火墙和selinux，可以在每台服务器上运行如下命令（操作节点：所有）
sed -i ‘s/SELINUX=enforcing/SELINUX=disabled/g‘ /etc/selinux/config systemctl stop firewalld systemctl disable firewalld setenforce 0
更改每台主机主机名，如下命令（操作节点：所有）
hostnamectl set-hostname hadoop1
每台主机上添加hosts解析（操作节点：所有）
echo " 192.168.16.134 hadoop1 192.168.16.135 hadoop2 192.168.16.136 hadoop3 192.168.16.137 hadoop4">>/etc/hosts
所有主机上创建hadoop用户（操作节点：所有）
useradd hadoop passwd hadoop
切换到普通用户，配置免密，（操作节点：hadoop1）
su - hadoop #ssh-keygen，一路回车即可 ssh-keygen #本机也要拷贝一份 ssh-copy-id -i ~/.ssh/id_rsa.pub hadoop@hadoop1 ssh-copy-id -i ~/.ssh/id_rsa.pub hadoop@hadoop2 ssh-copy-id -i ~/.ssh/id_rsa.pub hadoop@hadoop3 ssh-copy-id -i ~/.ssh/id_rsa.pub hadoop@hadoop4
