expect交互shell及一键部署服务

安装expect

yum install expect
expect -v

简单登陆命令

[root@localhost xxxx]# cat ssh.exp 
#!/usr/bin/expect 
set timeout 30
spawn ssh [email protected]
expect {
"*yes/no" {send "yes\r"; exp_continue}
"password:" {send "cc0214\r"}
}
interact   //放弃控制，可以手工操作

在shell脚本中执行

 expect -c   在命令行运行expect 脚本

 shell中使用expect -c "expect脚本内容"来完成嵌套。

[root@localhost xxxx]# cat jump.sh 
#!/bin/sh

echo "------------登陆···········"
expect -c "
   spawn ssh [email protected]
   expect {
                \"*(yes/no)?\"
                {
                        send \"yes\n\"
                        expect \"password:\" {
                                send \"cc0214\n\"
                        }
                }
                \"*password:\"
                {
                        send \"cc0214\n\"
                }
    }
interact "

只在另端执行命令（复制，或者执行他端shell）

echo "------------部署项目···········"

function exe()  //定义函数
{
expect -c "
        $1
        set timeout 300
        expect {
                \"*(yes/no)?\"
                {
                        send \"yes\n\"
                        expect \"password:\" {
                                send \"cc0214\n\"
                        }
                }
                \"*password:\"
                {
                        send \"cc0214\n\"
                }
        }
       expect eof
"
}

exe "spawn scp /home/wangdong/1.txt [email protected]:/home/wx/1.txt"  //传递执行命令参数

shell中多行expect命令的写法

expect<<-EOF
spawn xxxx
set timeout 10
expect "password"
expect eof
EOF


//*****或者

expect <
