linux下主从节点互相免密匙登陆

Posted 2020-10-21

  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 [email protected]:~
scp authorized_keys [email protected]:~
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 [email protected];
 输入此命令即可
