Oracle Study之-AIX6.1构建主机之间的信任关系(ssh)

   在AIX环境下构建主机信任关系首选rsh,但在构建Oracle 11g RAC时需要ssh支持,以下文档介绍如何在AIX6.1下构建ssh的信任关系。


   默认aix没有安装ssh软件包,首先要安装ssh软件包:

1、下载、解压软件包

[root@aix209 ssh]#ls
OpenSSH_5.8.0.6102.tar.Z  openssl-0.9.8.1802.tar.Z  ssh.txt

解压后通过smit installs安装:

[root@aix209 ssh]#uncompress OpenSSH_5.8.0.6102.tar.Z
[root@aix209 ssh]#uncompress openssl-0.9.8.1802.tar.Z

[root@aix209 ssh]#ls
OpenSSH_5.8.0.6102.tar  openssl-0.9.8.1802.tar  ssh.txt
[root@aix209 ssh]#tar xvf OpenSSH_5.8.0.6102.tar

2、通过smit installs安装:
[root@aix209 ssh]#smit installs


3、安装成功后,系统自动启动ssh service:
[root@aix209 ssh]#l***c -a |grep ssh
 sshd             ssh              6029368      active

4、配置信任关系(通过建立公钥和私钥)
[grid@aix209 grid]$ssh-keygen -t rsa

Generating public/private rsa key pair.
Enter file in which to save the key (/home/grid/.ssh/id_rsa): 
Created directory '/home/grid/.ssh'.
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:
46:8c:ac:aa:82:62:b1:5e:e2:ba:ed:d5:02:5e:f5:62 grid@aix209
The key's randomart image is:
+--[ RSA 2048]----+

|..=.o .          |
|==o. .           |
|X=o              |
+-----------------+

[grid@aix209 grid]$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:

[grid@aix209 .ssh]$ls

[grid@aix209 .ssh]$cd ..          

在另一个node(aix210)同样方式建立密钥对:

[grid@aix210 grid]$ssh-keygen -t rsa

[grid@aix210 grid]$ssh-keygen -t dsa                         

[grid@aix209 ~]$cat .ssh/id_rsa.pub >>.ssh/authorized_keys
[grid@aix209 ~]$cat .ssh/id_dsa.pub >>.ssh/authorized_keys
