mkgroup id=303 hagsuser
2个节点上的oracle用户id必需相同
使用smitty user命令创建，这里用户id定义成500，由于之前设置了全局默认的limit，创建用户时不需要再设置。
* User NAME [oracle]
User ID [500] #
ADMINISTRATIVE USER false +
Primary GROUP [oinstall] +
Group SET [dba,hagsuser]
也可用命令修改：
mkuser id=500 pgrp=oinstall groups=dba,hagsuser oracle
使用passwd命令修改oracle密码
# passwd oracle
Changing password for "oracle"
oracle's New password:
Enter the new password again:
****配置SSH信任，该方案作为一个可选方案配置，如果客户有特别要求*****
AIX默认没有安装ssl和ssh的包，无法用ssh方式连接，需要到ibm网站上下载安装包
openssl的下载地址：https://www14.software.ibm.com/webapp/iwm/web/reg/download.do source=aixbp&S_PKG=openssl&lang=en_US
openssh的下载地址：https://www14.software.ibm.com/webapp/iwm/web/reg/download.do source=aixbp&lang=en_US&S_PKG=openssh&cp=UTF-8
在2个节点都需要进行步骤<1>至<5>
<1>切换到oracle用户下
su - oracle
<2>创建ssh目录
mkdir ~/.ssh
<3>修改ssh目录权限，该步骤很重要
chmod 700 ~/.ssh
<4>创建RSA KEY
$ /usr/bin/ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/oracle/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/oracle/.ssh/id_rsa.
Your public key has been saved in /home/oracle/.ssh/id_rsa.pub.
The key fingerprint is:
fb:d4:c7:e0:d9:d2:ef:ef:e8:2e:04:44:24:db:1b:11 oracle@node1
The key's randomart image is:
+--[ RSA 2048]----+
| .oE. |
| +.. |
| ..o |
| .o |
| S ... |
| . o.* |
| . ..= = |
| o .o o |
| . ++o*|
+-----------------+
<5>生成DSA KEY
$ /usr/bin/ssh-keygen -t dsa
Generating public/private dsa key pair.
Enter file in which to save the key (/home/oracle/.ssh/id_dsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/oracle/.ssh/id_dsa.
Your public key has been saved in /home/oracle/.ssh/id_dsa.pub.
The key fingerprint is:
ae:13:a1:45:c3:8e:10:2a:ba:8c:68:cf:a2:ac:8a:74 oracle@node1
The key's randomart image is:
+--[ DSA 1024]----+
| .. . |
| .. + |
|o . + . |
|o . + |
|. o .S |
|+. . .. |
|++ E .. |
|=.+ .. |
|O..o .. |
+-----------------+
以上步骤在2个节点都要完成，以下步骤只需要节点1完成。
<6>创建authorized key文件
touch ~/.ssh/authorized_keys
cd ~/.ssh
<7>用ssh命令将信息拷贝到authorized key文件中
ssh node1 cat /home/oracle/.ssh/id_rsa.pub >> authorized_keys
ssh node1 cat /home/oracle/.ssh/id_dsa.pub >> authorized_keys
ssh node2 cat /home/oracle/.ssh/id_rsa.pub >> authorized_keys
ssh node2 cat /home/oracle/.ssh/id_dsa.pub >> authorized_keys
<8>复制authorized key文件到节点2相同位置
scp authorized_keys node2:/home/oracle/.ssh/
<9>修改文件属性
chmod 600 ~/.ssh/authorized_keys
<10>激活用户等价
exec /usr/bin/ssh-agent $SHELL
/usr/bin/ssh-add
<11>测试ssh信任，不需要输入密码
ssh node1 date
ssh node2 date
ssh node1_prv date
ssh node2_prv date
遇到Are you sure you want to continue connecting (yes/no) 输入yes，再test一次
