关闭防火墙：systemctl stop firewalld.service

重启网络服务：systemctl restart network.service

设置静态IP

设置/etc/hosts

192.168.232.133    cent-1
192.168.232.134    cent-2
192.168.232.135    cent-3

配置免密登录在往期的Hadoop配置中已有说明。

一、进入conf配置文件

配置Master

cp slaves.template slaves

vim slaves

cent-2

cent-3

修改spark-env.sh

cp spark-env.sh.template spark-env.sh

vi spark-env.sh
