SUSE+linux+配置节点间的SSH信任关系

 

配置节点间的SSH信任关系

（1）在节点1上

oracle@node1:~ > pwd

/home/oracle

oracle@node1:~ > mkdir .ssh

oracle@node1:~ > chmod 700 .ssh   #这一步很重要，而且必须是700权限，否则失败

oracle@node1:~ > ssh-keygen –t rsa

oracle@node1:~ > ssh-keygen –t dsa

oracle@node1:~ > cd .ssh ; ls

id_dsa  id_dsa.pub  id_rsa  id_rsa.pub

（2）在节点2上

oracle@node2:~ > pwd

/home/oracle

oracle@node2:~ > mkdir .ssh

oracle@node2:~ > chmod 700 .ssh   #这一步很重要，而且必须是700权限，否则失败

oracle@node2:~ > ssh-keygen –t rsa

oracle@node2:~ > ssh-keygen –t dsa

oracle@node2:~ > cd .ssh ; ls

id_dsa  id_dsa.pub  id_rsa  id_rsa.pub

（3）建立信任关系

oracle@node1:~/.ssh > cat id_rsa.pub >> authorized_keys

oracle@node1:~/.ssh > cat id_dsa.pub >> authorized_keys

oracle@node1:~/.ssh > ssh node2 cat /home/oracle/.ssh/id_rsa.pub >> authorized_keys

oracle@node1:~/.ssh > ssh node2 cat /home/oracle/.ssh/id_dsa.pub >> authorized_keys

oracle@node1:~/.ssh > scp authorized_keys node2:/home/oracle/.ssh/

（4）测试信任关系

oracle@node1:~ > ssh node2 date

oracle@node2:~ > ssh node1 date 

均不用输入密码，则信任关系建立完毕！
