下面是在centos7 minial环境下测试通过的一段sh脚本,利用expect命令,对远端设备自动执行命令
首先要安装expect
远程执行 ssh -o
ssh -o 'StrictHostKeyChecking no' 'appdeploy@10.71.2.156' -a "uptime"
# yum install expect
#cat test.sh
#!/bin/bash
user=root
pass='远端设备口令'
ip=$1
/usr/bin/expect << FLAGEOF
set timeout 2
spawn ssh $user@$ip
expect {
"(yes/no)" {send "yes\r"; exp_continue}
"password:" {send "$pass\r"}
}
expect "root@*" {send "df -h\r"}
expect "root@*" {send "yum -y install wget\r";set timeout -1}
expect "root@*" {send "exit\r"}
expect eof
FLAGEOF
执行
#sh test.sh 远端设备ip地址
