这篇文章主要介绍Oracle Study在AIX环境下如何构建主机信任关系，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！

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@aix209The key's randomart p_w_picpath is:+--[ RSA 2048]----+|                 ||     . o         ||      + o        ||     o o         ||  . o E S        || o + o o         ||..=.o .          ||==o. .           ||X=o              |+-----------------+

[grid@aix209 ~]$cd .ssh
[grid@aix209 .ssh]$ls
id_dsa id_dsa.pub id_rsa id_rsa.pub
[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
[grid@aix209 ~]$ssh aix210 cat .ssh/id_rsa.pub >>.ssh/authorized_keys
