基于CentOS与VmwareStation10搭建Oracle11G RAC 64集群环境：2.搭建环境-2.9. 配置用户等效性(可选项)

1.以下均以grid用户执行: 在两个节点的grid主目录分别创建.ssh目录，并赋予权限

linuxrac1

[grid@linuxrac1 ~]$mkdir ~/.ssh

[grid@linuxrac1 ~]$chmod 755 ~/.ssh

[grid@linuxrac1 ~]$ssh-keygen -t rsa

Generating public/private rsa key pair.

Enter file in which to save the key (/home/grid/.ssh/id_rsa):

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Your identification has been saved in /home/grid/.ssh/id_rsa.

Your public key has been saved in /home/grid/.ssh/id_rsa.pub.

The key fingerprint is:

7a:7b:62:31:da:07:88:0d:22:46:46:28:d1:cc:87:e1 grid@linuxrac1

[grid@linuxrac1 ~]$ssh-keygen -t dsa

Generating public/private dsa key pair.

Enter file in which to save the key (/home/grid/.ssh/id_dsa):

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Your identification has been saved in /home/grid/.ssh/id_dsa.

Your public key has been saved in /home/grid/.ssh/id_dsa.pub.

The key fingerprint is:

19:3b:fc:23:85:8d:f4:58:7d:f6:fd:80:99:ce:f8:52 grid@linuxrac1

linuxrac2

[grid@linuxrac2 ~]$ mkdir ~/.ssh

[grid@linuxrac2 ~]$ chmod 755 ~/.ssh

[grid@linuxrac2 ~]$ ssh-keygen -t rsa

Generating public/private rsa key pair.

Enter file in which to save the key (/home/grid/.ssh/id_rsa):

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Your identification has been saved in /home/grid/.ssh/id_rsa.

Your public key has been saved in /home/grid/.ssh/id_rsa.pub.

The key fingerprint is:

69:8c:94:2b:2b:a4:8d:33:82:8f:b0:49:03:a1:1a:b9 grid@linuxrac2

[grid@linuxrac2 ~]$ ssh-keygen -t dsa

Generating public/private dsa key pair.

Enter file in which to save the key (/home/grid/.ssh/id_dsa):

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Your identification has been saved in /home/grid/.ssh/id_dsa.

Your public key has been saved in /home/grid/.ssh/id_dsa.pub.

The key fingerprint is:

1f:4d:e7:3f:c7:4d:d8:f0:55:f0:eb:c1:ea:74:93:24 grid@linuxrac2

以上用默认配置,一路回车即可

linuxrac1

cat ~/.ssh/*.pub >> ~/.ssh/authorized_keys

ssh grid@linuxrac2 cat ~/.ssh/*.pub >> ~/.ssh/authorized_keys

或

ssh grid@linuxrac2 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

ssh grid@linuxrac2 cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

grid@linuxrac1 ~]$ cd .ssh

[grid@linuxrac1 .ssh]$ ll

total 48

或

ssh grid@linuxrac1 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

ssh grid@linuxrac1 cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

2.建立等效性 rac1,rac2双节点执行

[grid@linuxrac1 ~]$ exec ssh-agent $SHELL

[grid@linuxrac1 ~]$ ssh-add

Identity added: /home/grid/.ssh/id_rsa (/home/grid/.ssh/id_rsa)

[grid@linuxrac1 ~]$ ssh linuxrac1 date

[grid@linuxrac1 ~]$ ssh linuxrac1-priv date

[grid@linuxrac1 ~]$ ssh linuxrac2 date

[grid@linuxrac1 ~]$ ssh linuxrac2-priv date

ssh linuxrac1 date; ssh linuxrac2 date

[grid@linuxrac2 ~]$ exec ssh-agent $SHELL

[grid@linuxrac2 ~]$ ssh-add

Identity added: /home/grid/.ssh/id_rsa (/home/grid/.ssh/id_rsa)
