一、问题描述

[omm@opengauss03 ~]$ gs_check -i CheckCPU
Parsing the check items config file successfully
[GAUSS-53026]: ERROR: Execute SSH command on host 192.168.56.19 faild. The exception is:

二、问题原因

数据库所在主机之间没有实现SSH免密登录

三、解决方法

1. 切换到omm系统用户下，执行如下命令生成密钥对

   gs_sshexkey -h 192.168.56.19
   

   注意：-h 后面的IP地址换成你自己环境中数据库所在主机IP地址

   
   该命令执行成功后，会在omm用户家目录下生成一个隐藏目录.ssh，在该.ssh目录下生成了密钥对，如下所示：
   

2. 重新执行openGauss服务器端命令，如下所示，正常显示

   [omm@opengauss03 ~]$ gs_check -i CheckDBConnection
   Parsing the check items config file successfully
   Distribute the context file to remote hosts successfully
