GBase 8c部署准备(五):创建gbase用户免密登录

所有节点创建gbase用户免密登录:

[gbase@localhost ~]$ mkdir ~/.ssh

[gbase@localhost ~]$ chmod 700 ~/.ssh

在任意节点均可进行数据库集群部署操作。通常采用在GTM节点进行GBase 8c数据库集群部署的方式。在执行部署脚本服务器上,gbase用户需配置免密登录其他服务器。

免密登录配置操作如下(以下操作仅在GTM节点进行):

gbase用户生成认证文件:

[gbase@localhost ~]$ ssh-keygen -t rsa

[gbase@localhost ~]$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

[gbase@localhost ~]$ chmod 600 ~/.ssh/authorized_keys

将秘钥文件拷贝至其他节点(此操作需输入密码):

[gbase@localhost ~]$ scp ~/.ssh/authorized_keys gbase@192.168.142.210:~/.ssh/

[gbase@localhost ~]$ scp ~/.ssh/authorized_keys gbase@192.168.142.211:~/.ssh/

[gbase@localhost ~]$ scp ~/.ssh/authorized_keys gbase@192.168.142.212:~/.ssh/

[gbase@localhost ~]$ scp ~/.ssh/authorized_keys gbase@192.168.142.213:~/.ssh/
