The following error occurs when the master host remotely connects to the slaves via SSH

Second, re-execute SCP id_dsa.pub slaves:/root.ssh command on Master machine (execute in/root/.ssh directory)

Third, log into the slaves machine, enter into the ROOT/.SSH directory to execute the cat id_dsa.pub >>authorized_keys command

After you complete the above steps, the problem is resolved
