线上服务器会对ssh服务改为非22端口，这时候，在服务器之间创建双机互信的状况下，若使用ssh-copy-id命令，不通过特定的语法，会报错。服务器

[root@localhost ~]# ssh-copy-id -i  /root/.ssh/id_rsa.pub  -p 10022 root@*.*.*.*
Bad port 'umask 077; test -d ~/.ssh || mkdir ~/.ssh ; cat >> ~/.ssh/authorized_keys && (test -x /sbin/restorecon && /sbin/restorecon ~/.ssh ~/.ssh/authorized_keys >/dev/null 2>&1 || true)'

对于非22端口状况下的ssh-copy-id的使用，须要这样用：ssh

[root@localhost ~]# ssh-copy-id -i  /root/.ssh/id_rsa.pub  '-p 20460 root@*.*.*.*'
Now try logging into the machine, with "ssh '-p 10022 root@*.*.*.*'", and check in:
 
  .ssh/authorized_keys
 
to make sure we haven't added extra keys that you weren't expecting.
