start-slave.sh failed with ssh port other than 22

[ZhuGe]

Hi all:I am new to spark and i want to set up a cluster of 3 nodes( standalone 
mode)I can start the master and see the web ui.Because the ssh port of the 3 
nodes is configured to 58518, so when i use sbin/start-slave.sh, the log 
message shows ssh: connect to host node1 port 22: connection refused.What 
should i do to  start all the slaves without change the port 58518 to 22.
Thanks
