无特殊说明三台机器都进行操作

下载地址

https://mirrors.tuna.tsinghua.edu.cn/apache/hadoop/common/stable/hadoop-3.4.0.tar.gz

此处本人解压到/root/hadoop-3.4.0，如果解压到其他地方下面有关路径的需要自行修改

修改三台机器host文件

vim /etc/hosts
192.168.31.210 node1
192.168.31.130 node2
192.168.31.250 node3

配置机器固定ip

vim /etc/sysconfig/network-scripts/ifcfg-ens33
ZONE=public
HWADDR=00:50:56:2C:43:7C
IPADDR=192.168.31.250
NETMASK=255.255.255.0
GATEWAY=192.168.59.255
DNS1=192.168.59.255

重启网卡服务

systemctl restart network

配置三台机器互信

su root -
ssh-keygen -t rsa -b 4096
ssh-copy-id 192.168.31.210
ssh-copy-id 192.168.31.130
ssh-copy-id 192.168.31.250

配置文件

进入hadoop解压后目录
cd /root/hadoop-3.4.0

vim etc/hadoop/workers
