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

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

?

1 2 3 4 5 6 7 8 9 10 11 12 13

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.
