ssh远程执行命令方法和Shell脚本实例

-t      Force pseudo-tty allocation.  This can be used to execute arbitrary screen-based programs on a remote machine, which can be very useful, e.g. when implementing menu services.  Multiple -t options force tty allocation, even if ssh has no local tty.  

ssh -t -p $port $user@$ip  'cmd'  

#!/bin/bash  
  
#变量定义  
ip_array=("192.168.1.1" "192.168.1.2" "192.168.1.3")  
user="test1"  
remote_cmd="/home/test/1.sh"  
  
#本地通过ssh执行远程服务器的脚本  
for ip in ${ip_array[*]}  
do  
    if [ $ip = "192.168.1.1" ]; then  
        port="7777"  
    else  
        port="22"  
    fi  
    ssh -t -p $port $user@$ip "remote_cmd"  
done
