功能

主备集群配置互信并校验互信，方便主备集群容灾过程中免密执行命令、传送文件。

命令格式

python3 $GPHOME/script/ESLDoTrust.py -f <trustFile> [-l <logFile>]

参数说明

使用指南

• ESLDoTrust.py需要在主集群的主节点上登录账号执行，需要用户账号密码和root密码。命令包含配置互信、校验互信等操作。
• 互信文件格式如下：

  192.168.240.1
  192.168.240.2
  192.168.240.3
  192.168.240.4
  192.168.240.5
  192.168.240.6

命令示例

python3 $GPHOME/script/ESLDoTrust.py -f /home/omm/cluster_ssh
