Try this...
Code:
#!/bin/bash
password="password"
server1="10.251.222.51"
server=($server1)

for exp_server in ${server[@]}; 
do
        expect -c "
        spawn ssh $exp_server last reboot > /tmp/log
        expect \"*password* \" { send -- \"$password\n\" }
        interact; exit" 
done

We strongly advice you to use passwordless ssh!!!

       Use the stop-instance to stop the instance with the instance name specified. The stop-instance can be run both locally and  remotely.   The
