Still connect 22 ssh port when using gpinitsystem command of Greenplum withing different ssh port of-CodePudding

I want to install Greenplum in CentOS7.9 which is changed default ssh port to 10022. I changed 'gpssh-exkeys' script to add '-p 10022' for all of ssh command and add '-P 10022' for all of scp command. And run it is ok. Then I changed '/usr/local/greenplum-db/lib/python/gppylib/commands/base.py' script to add '-p 10022' in a ssh command line.

        # Escape " for remote execution otherwise it interferes with ssh
        cmd.cmdStr = cmd.cmdStr.replace('"', '\\"')
        cmd.cmdStr = "ssh -p 10022 -o StrictHostKeyChecking=no -o ServerAliveInterval=60 " \
                     "{targethost} \"{gphome} {cmdstr}\"".format(targethost=self.targetHost,
                                                                 gphome=". %s/greenplum_path.sh;" % self.gphome,
                                                                 cmdstr=cmd.cmdStr)

But I got the error that present still try to connent port 22 when run 'gpinitsystem'.

And I didn't find official documents, https://docs.greenplum.org/, for guiding how to install withing the different ssh port.

Thank you!

CodePudding user response：

Do not modify delivered utilities. Recommend leveraging ~gpadmin/.ssh/config specifying Port for your hosts. All Greenplum utilities should honor settings in that file.

Example ~gpadmin/.ssh/config where all hosts are known as sdw1-pri, sdw2-pri and so on:

Host sdw*-pri
    Port 10022

CodePudding user response：

Can you specify the 10022 port in /etc/sshd_config and try again.
