oracle 11g r2 rac ssh两节点互信对等配置Permission denied (publickey,gssapi-with-mic,password)

问题：安装oracle 11g r2 RAC grid 时，配置两节点ssh互信对等配置不成功,具体错误信息如下：

------------------------------------------------------------------------

Verifying SSH connectivity has been setup from rac1 to rac1

------------------------------------------------------------------------

IF YOU SEE ANY OTHER OUTPUT BESIDES THE OUTPUT OF THE DATE COMMAND OR IF YOU ARE PROMPTED FOR A PASSWORD HERE, IT MEANS SSH SETUP HAS NOT BEEN SUCCESSFUL.

grid@rac1's password: 

Permission denied, please try again.

Permission denied, please try again.

Permission denied (publickey,gssapi-with-mic,password).

------------------------------------------------------------------------

配置ssh对等的时候的运用脚本如下：

./sshUserSetup.sh -user grid -hosts "rac1 rac2" -advanced -exverify -confirm -noPromptPassphrase

环境为 oracle linux 5.5,RAC两节点的主机名为：rac1 rac2。

原始配置/etc/ssh/sshd_config文件为：

# This sshd was compiled with PATH=/usr/local/bin:/bin:/usr/bin

# The strategy used for options in the default sshd_config shipped with

# OpenSSH is to specify options with their default value where

# possible, but leave them commented.  Uncommented options change a

# default value.

#Protocol 2,1

Protocol 2

# Authentication:

#RSAAuthentication yes

#PubkeyAuthentication yes

#AuthorizedKeysFile     .ssh/authorized_keys

# For this to work you will also need host keys in /etc/ssh/ssh_known_hosts

#RhostsRSAAuthentication no

# similar for protocol version 2

#HostbasedAuthentication no

# Change to yes if you don't trust ~/.ssh/known_hosts for

# RhostsRSAAuthentication and HostbasedAuthentication

#IgnoreUserKnownHosts no

# Don't read the user's ~/.rhosts and ~/.shosts files

#IgnoreRhosts yes

# To disable tunneled clear text passwords, change to no here!

#PasswordAuthentication yes

#PermitEmptyPasswords no

PasswordAuthentication yes

# Change to no to disable s/key passwords

#ChallengeResponseAuthentication yes

ChallengeResponseAuthentication no

#KerberosGetAFSToken no

# GSSAPI options

#GSSAPIAuthentication no

GSSAPIAuthentication yes

#GSSAPICleanupCredentials yes

GSSAPICleanupCredentials yes

# Set this to 'yes' to enable PAM authentication, account processing,

# and session processing. If this is enabled, PAM authentication will

# be allowed through the ChallengeResponseAuthentication mechanism.

# Depending on your PAM configuration, this may bypass the setting of

# PasswordAuthentication, PermitEmptyPasswords, and

# "PermitRootLogin without-password". If you just want the PAM account and

# session checks to run without PAM authentication, then enable this but set

# ChallengeResponseAuthentication=no

#UsePAM no

UsePAM yes

解决方案：

根据错误提示“Permission denied (publickey,gssapi-with-mic,password).“

于是打开/etc/ssh/sshd_config配置文件，将上述标红的配置修改

#RSAAuthentication yes

PubkeyAuthentication yes

AuthorizedKeysFile     .ssh/authorized_keys

启用publickey认证，同时必须保证PasswordAuthentication yes必须yes状态。

重启ssh服务

service sshd restart

然后再运行脚本，

./sshUserSetup.sh -user grid -hosts "rac1 rac2" -advanced -exverify -confirm -noPromptPassphrase

ssh 对等互信配置成功
