19c GI互信报错 II [INS-06006] PRVG-2019 PRKN-1038

配置互信的时候报错，再一次，，这一次和前一次不一样，报错如下。 [INS-06006] Passwordless SSH connectivity not set up between the following node(s): [rac1, rac2] Cause - Either passwordless SSH connectivity is not setup between specified node(s) or they are not reachable. Refer to the logs for more details.  Action - Refer to the logs for more details or contact Oracle Support Services.  More Details PRVG-2019 : Check for equivalence of user "grid" from node "rac1" to node "rac2" failed PRKN-1038 : The command "/usr/bin/ssh -o FallBackToRsh=no  -o PasswordAuthentication=no  -o StrictHostKeyChecking=yes  -o NumberOfPasswordPrompts=0  rac2 -n /bin/true" run on node "rac1" gave an unexpected output: "sign_and_send_pubkey: signing failed: agent refused operationPermission denied (publickey,gssapi-keyex,gssapi-with-mic,password)." 其实根据日志和报错信息，我已经setup成功了，在grid 用户下执行 /usr/bin/ssh -o FallBackToRsh=no  -o PasswordAuthentication=no  -o StrictHostKeyChecking=yes  -o NumberOfPasswordPrompts=0  rac2 -n /bin/true 的时候，其实是不报错的。并且ssh node2 date也是成功的。无奈之下，mos上搜一把 mos上参考GI runInstaller Fails with INS-6006 in VNC During SSH test even though SSH Setup is successful (Doc ID 2070270.1) action: rac1:grid用户 export SSH_AUTH_SOCK=0 再跑图形界面安装GI，就成功了
