expect--自动批量分发公钥脚本

1.在使用之前，先安装epel源，yum install expect -y
2.写分发脚本，后缀为exp

?

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

#!/usr/bin/expect set host_ip [lindex $argv 0] spawn ssh-copy-id -i /root/.ssh/id_rsa.pub $host_ip expect {         -timeout 60         "(yes/no)?" { send "yes\n";exp_continue}         "password:" { send "Ak46\n"}         timeout {puts "Connect timeout!";return} } expect eof exit -onexit {         send_user "Job has finished!" }

注：set的作用是设置变量，spawn设置执行命令时，可以引用变量；变量的第一个参数为0
3.执行以下命令开始分发

?

1	for ip in `cat /root/ip.txt`;do expect /root/fenfa_sshkey.exp $ip ;done
