在原有集群无密码访问的基础上,将新增节点机器的无密码访问加入集群中,具体步骤如下:
su - root
vim /etc/ssh/ssh_config
将StrictHostKeyChecking修改为no:
StrictHostKeyChecking no
执行ssh-keygen -t rsa命令,当出现”Enter Passphrase“的提示时直接按回车。
[root@rhino130 ~]# ssh-keygen -t rsa
[root@rhino130 ~]# ssh-copy-id rhino130
[root@rhino130 ~]# ssh-copy-id rhino131
[root@rhino130 ~]# ssh-copy-id rhino132
[root@rhino130 ~]# ssh-copy-id rhino133
下面这一步骤不一定要执行
[root@rhino131 ~]# scp ~/.ssh/authorized_keys root@rhino130:~/.ssh/
