expect模块的使用

第一步首先下载expect 模块,yum list |grep expect ,安装下面的模块.

expect.x86_64                               5.44.1.15-5.el6_4           @base  
expect-devel.x86_64                         5.44.1.15-5.el6_4           @base

安装完成后,可以在程序which expect下面可以查看环境/usr/bin/expect,需要expect和tcl两个包

 rpm -qa tcl
tcl-8.5.7-6.el6.x86_64
[root@ob ~]# rpm -qa | grep expect
expect-5.44.1.15-5.el6_4.x86_64
expect-devel-5.44.1.15-5.el6_4.x86_64

贴两个代码

 cat test1.sh 
#!/usr/bin/expect

SERVERS="192.168.79.129  192.168.79.131"
PASSWORD=123456

auto_ssh_copy_id() {
    echo "2"
    expect -c "set timeout -1;
        spawn scp -r /root/app root@$1:/root/;
        expect {
            *(yes/no)* {send -- yes\r;exp_continue;}
            *assword:* {send -- $2\r;exp_continue;}
            eof        {exit 0;}
        }";
}

sh_copy_id_to_all() {
    echo "111"
    for SERVER in $SERVERS
    do
        auto_ssh_copy_id $SERVER $PASSWORD
        echo ${SERVER}
    done
}
sh_copy_id_to_all

　

next code

SERVER="192.168.79.129  192.168.79.131"

auto_zookp_cp() {
    expect {*yes/no* {send "yes\r"}
    expect {*password* {send "123456\r"}
}


for myserver in ${SERVER}
do
    scp -r /root/app root@${myserver}:/root/
    auto_zookp_cp
done

　　use sh to execute the shell,otherwise it wiil produce an error.
