背景

linux7.6上搭建18cRAC

安装集群配置互信test时报错INS-44000

报错信息：passwordless ssh connectivity is not setup from the local node node1 to the following nodes node2

处理过程

1、无论是手工配置互信，还是在图形界面setup都是不行；手动执行ssh没有问题。
2、查看openssh版本

ssh -V
是 OpenSSH_8.1.p1的版本。

3、查看mos发现文档 ID 2555697.1 比较匹配
INS-06006 GI RunInstaller Fails If OpenSSH Is Upgraded to 8.x

原因是OpenSSH升级到了8.x版本。

4、根据文档处理过程：
–Before installation, as root user: (please change the path if the location of your “scp” is not the same with below)

1）Rename the original scp.
mv /usr/bin/scp /usr/bin/scp.orig

2）Create a new file </usr/bin/scp>.
vi /usr/bin/scp

3）Add the below line to the new created file </usr/bin/scp>.
/usr/bin/scp.orig -T $*

4）Change the file permission.
chmod 555 /usr/bin/scp

After installation:
mv /usr/bin/scp.orig /usr/bin/scp

根据mos文档处理后互信验证通过。
