[INS-06006] Passwordless SSH connectivity not set up
一、环境说明：
DB版本：Oracle 11.2.0.4
OS版本：Redhat 6.4
二、处理方法
1、使用ssh验证等效性
[grid@jzh03 ~]$ date;ssh jzh03 date
Wed Dec 10 17:06:23 CST 2014
Wed Dec 10 17:06:24 CST 2014
[grid@jzh03 ~]$ date;ssh jzh04 date
Wed Dec 10 17:06:51 CST 2014
Wed Dec 10 17:06:51 CST 2014
结果依然报错。
2、修改grid用户密码
[root@jzh03 Desktop]# passwd grid
Changing password for user grid.
New password:
BAD PASSWORD: it is too short
BAD PASSWORD: is too simple
Retype new password:
passwd: all authentication tokens updated successfully.
结果依然报错。
3、修改.ssh目录
[root@jzh03 grid]# chmod 700 .ssh
[root@jzh03 grid]# ls -la
total 44
drwxr-xr-x 5 grid oinstall 4096 Dec 11 10:48 .
drwxr-xr-x. 4 root root 4096 Dec 11 10:21 ..
-rw------- 1 grid oinstall 66 Dec 11 10:59 .bash_history
-rw-r--r-- 1 grid oinstall 18 Aug 29 2012 .bash_logout
-rw-r--r-- 1 grid oinstall 472 Dec 11 10:37 .bash_profile
-rw-r--r-- 1 grid oinstall 124 Aug 29 2012 .bashrc
drwxr-xr-x 2 grid oinstall 4096 Jul 14 2010 .gnome2
-rw-r--r-- 1 grid oinstall 124 Jun 28 2011 .mkshrc
drwxr-xr-x 4 grid oinstall 4096 Nov 13 06:37 .mozilla
drwx------ 2 grid oinstall 4096 Dec 11 10:55 .ssh
-rw------- 1 grid oinstall 646 Dec 11 10:37 .viminfo
结果依然报错。
4、删除手工配置的ssh,采用grid infrastructure配置--->依然报错。
5、上MOS查找相关文章，发现11.2.0.4 runInstaller: [INS-06006] Passwordless SSH connectivity not set up between the following nodes(s) (文档 ID 1597212.1)，描述如下：
Installing 11.2.0.4 Grid Infrastructure patch set, runInstaller reports error: [INS-06006] Passwordless SSH connectivity not set up between the following nodes(s): [racnode1].

- hostname is in mixed case (in this example upper case)
10.0.0.101 RACNODE1.US.ORACLE.COM RACNODE1
10.0.0.102 RACNODE2.US.ORACLE.COM RACNODE2
The workaround is to either allow OUI or manually (note 300548.1) setup ssh user equivalence for the installing user, then in command line window, ensure ssh doesn't prompt for password for both real hostname and lower case hostname.
For example:
Fri Nov 8 10:01:03 PST 2013
$ ssh racnode1 date ====>> lower case hostname for node1
Fri Nov 8 10:01:04 PST 2013
$ ssh RACNODE2 date
Fri Nov 8 10:01:05 PST 2013
$ ssh racnode2 date
Fri Nov 8 10:01:06 PST 2013
In the case of upgrade, the alternate workaround is to update inventory to set to lower case nodename instead of real hostname:
Note in above command it's racnode1,racnode2 in lower case despite the hostname is upper case.
原来是个bug，想不到第一次安装11.2.0.4就遇到bug，将主机名全部改为小写之后就顺利安装成功了。来自 “ ITPUB博客 ” ，链接：https://blog.itpub.net/21302630/viewspace-1590930/ ，如需转载，请注明出处，否则将追究法律责任。
