1、關於互信,可以手工配置互信,更改回rsa加密算法協議
--ssh-keygen 生成openssh協議秘鑰后,使用以下命令,將秘鑰變更為rsa協議
ssh-keygen -p -N "" -m pem -f /home/grid/.ssh/id_rsa
ssh-keygen -p -N "" -m pem -f /home/oracle/.ssh/id_rsa
2、關於互信中的ins-06006報錯
參考mos:INS-06006 GI RunInstaller Fails If OpenSSH Is Upgraded to 8.x (Doc ID 2555697.1)
本質上是openssh的scp引起,根據mos采用變通方式
3、安裝GI、DB軟件推送期間報錯 ins-10113
參考MOS:19c [INS-10113] And PRCF-2041 When Installing 3 Nodes RAC (Doc ID 2662954.1) To BottomTo Bottom
依然是openssh引起的問題,根據mos采取變通解決方式
export SRVM_DISABLE_MTTRANS=true
./gridSetup.sh
4、安裝RU補丁報錯 OPATCHAUTO-72030 Cannot execute in rolling mode, as CRS home is shared
原因,centos8版本對19c兼容性問題
解決方案:
export CV_ASSUME_DISTID=OEL8.1
Values like OEL7.6 to OEL7.8 are also workable。
