节点1dbca创建rac实例导致ssh节点2：Connection reset by peer（Node 1dbca creates RAC instance, resulting in SSH n）

在节点1打开dbca创建一套rac实例，执行到先决条件检查步骤时出现大量报错，但是根据报错信息检查环境时没有发现问题。检查后发现dbca所在服务器ssh另一个节点服务器会报错：Connection reset by peer。此问题导致节点1无法ssh到节点2创建目录及文件，最终导致dbca建库失败。

In node 1, open DBCA to create a set of Rac instances. A large number of errors are reported when performing the prerequisite check step, but no problems are found when checking the environment according to the error information. After checking, it is found that the server where the DBCA is located SSH another node server will report an error ：connection reset by peer. This problem makes node 1 unable to SSH to node 2 to create directories and files, which eventually leads to the failure of DBCA database building.
