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/expectSERVERS="192.168.79.129  192.168.79.131"PASSWORD=123456auto_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_cpdone

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