安装了三个节点，master,slave1,slave2

1.主节点免密匙登陆从节点

主机点窗口输入 ssh-keygen -t rsa 一路回车下去2.然后输入cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

chmod 600 ~/.ssh/authorized_keys

3.然后将authorized_keys发送到从节点slave1，slave2

scp authorized_keys zkpk@slave1:~ scp authorized_keys zkpk@slave2:~4.从节点生成密匙按照第一个步骤 5.将authorized_keys移动到 .ssh目录下修改权限chmod 600 ~/.ssh/authorized_keys

6.从节点登陆主节点，以及从节点之间互相登陆

cd .ssh

ssh-copy-id -i id_rsa.pub zkpk@master; 输入此命令即可
